README
๐ง Under active development. This extension is in
betastate and evolving fast. Tool signatures, settings keys, and the upcomingAbstractCustomToolAPI may still change between minor versions. Production deployments are possible (and encouraged for early feedback), but pin a version and review the changelog before upgrading. Join us on Slack โ #ai-suite on TYPO3 Slack โ to follow development, raise issues, or shape the roadmap.
MCP (Model Context Protocol) server integration for TYPO3's AI Suite extension. Connects Claude Desktop, Claude.ai, ChatGPT, MCP Inspector and other MCP-compatible clients directly to your TYPO3 backend โ and lets the model drive the same AI providers (Anthropic, OpenAI, Mittwald AI, DeepL, Midjourney, Flux, โฆ) that AI Suite already integrates.
What you can do with it
Once connected, your MCP client can drive the TYPO3 backend the same way an editor would โ but without leaving the chat.
- ๐งญ Walk the page tree, read pages, search content โ the model gets first-class access to every page, content element and FAL file the BE user can see.
- โ๏ธ Generate & optimize content โ full tt_content elements, landing pages, complete page trees from a single prompt, plus rewrite / shorten / simplify on existing copy.
- ๐ Translate anything โ single records, complete pages, file metadata, or whole folders in one batch. Includes Easy Language rewrites for accessible content.
- ๐ท๏ธ Fill in metadata at scale โ SEO titles, descriptions, OG / Twitter tags, alt texts, file metadata. Single record or bulk over a whole folder / page subtree.
- ๐ผ๏ธ Generate images straight into FAL โ the result lands as a real
sys_file, ready to be referenced. - ๐งฑ Edit records safely โ every CRUD tool runs through DataHandler with a mandatory preview / confirm step before anything is persisted.
- ๐งฐ Workspace-aware writes โ auto-routes changes through TYPO3 workspaces when EXT:workspaces is loaded; tokens can even be pinned to a specific workspace.
- ๐งฉ Works with EXT:container and your custom records โ container children, third-party tables (news, products, custom CTypes) are first-class.
- โฑ๏ธ Background batch jobs โ long-running translations / metadata generation get an async task ID; results come back as suggestions you approve.
- ๐ Production-grade auth โ OAuth 2.1 + PKCE with dynamic client registration, per-token rate limiting, full HTTPS enforcement, password-change revocation.
- ๐ค Respects TYPO3 BE-user permissions โ every tool call runs as the linked backend user; page mounts, file mounts, table/field access rights and AI Suite per-feature/per-model BE-group flags are enforced on every request.
- ๐ Reports + dedicated logs โ TYPO3 Reports module flags misconfigurations; two log streams (verbose + WARNING-only) keep ops monitoring simple.
AI capabilities & available models
MCP tools delegate the actual generation / translation work to the parent AI Suite extension โ so every model you've licensed there is also available to your MCP client. Permissions are still gated per BE-group feature flag and per AI model.
| Capability | MCP tools | Models available via AI Suite |
|---|---|---|
| Page metadata (SEO, OG, Twitter) | generateMetadata, batchGenerateMetadata |
ChatGPT, Anthropic, Mittwald AI, Meta Llama-3.3 (70B-Instruct) |
| File metadata (alt, title, description) | generateFileMetadata, batchGenerateFileMetadata, batchGenerateFolderMetadata |
ChatGPT Vision, Mittwald AI Vision, Meta Llama-3.3 (70B-Instruct) |
| Content generation (tt_content) | generateContent, optimizeContent |

Installation
composer require autodudes/ai-suite-mcp vendor/bin/typo3 extension:setup
Configuration
All settings live under Admin Tools โ Settings โ Extension Configuration โ ai_suite_mcp.
| Setting | Default | Description |
|---|---|---|
enableMcp |
0 |
Master switch for the MCP endpoint. While disabled, all /aisuite-mcp* requests return 404 mcp_disabled. |
mcpTokenLifetimeDays |
30 |
OAuth access-token lifetime in days. |
mcpAllowedOrigins |
(empty) | Comma-separated CORS origin allowlist. In production an empty value means "no CORS headers" (same-origin only). In development an empty value means "any origin allowed". |
mcpAllowedClientIds |
(empty) | Comma-separated allowlist of OAuth client_id values. Empty = all clients allowed. |
mcpAllowHttp |
0 |
Allow the MCP endpoint over unencrypted HTTP. Never enable this in production โ Bearer tokens would travel in clear text. Localhost and *.ddev.site are always exempted from HTTPS enforcement. |
mcpWriteMode |
auto |
How write tools persist data โ see Write modes. |
mcpSessionTimeoutSeconds |
1800 |
Drop idle MCP sessions after N seconds. 0 = SDK default (3600). Lower values free PHP workers and reduce session-store bloat. |
mcpAllowedRedirectUris |
(empty) | Comma-separated allowlist of external OAuth redirect URIs. Matched by prefix (str_starts_with). http://localhost, http://127.0.0.1 and http://[::1] are always accepted regardless of this setting. |
mcpExcludedTables |
(empty) | Comma-separated list of tables that MCP tools must not read or write. Applied on top of TYPO3 backend permissions and also blocks admins โ use to hide sensitive tables (e.g. be_users, fe_users, sys_log) from MCP clients regardless of the user's TYPO3 role. |
mcpTrustedProxies |
(empty) | Comma-separated reverse-proxy IPs / CIDRs (e.g. 10.0.0.0/8,192.168.0.0/16). When set, OAuth audit-log entries resolve the real client IP from X-Forwarded-For instead of the proxy peer IP. Empty = X-Forwarded-For is ignored and the raw peer IP is logged. See Reverse proxy & load balancer. |
Logging settings (mcpLogVerbose, mcpLogRedactionPatterns) are documented under Logging & retention; the media-upload settings (mcpMediaDefaultFolder, mcpMediaMaxSizeMb, mcpMediaAllowedExtensions, mcpMediaAllowUrlFetch, mcpMediaHostDenylist) under the uploadMedia tool.
Known MCP client callback URLs
Copy these into mcpAllowedRedirectUris / mcpAllowedOrigins for every client you want to support.
| Client | redirect_uri โ mcpAllowedRedirectUris |
Browser origin โ mcpAllowedOrigins |
|---|---|---|
| Claude.ai / Claude Desktop (remote connector) | https://claude.ai/api/mcp/auth_callback |
https://claude.ai |
| ChatGPT (MCP connector) | https://chatgpt.com/connector_platform_oauth_redirect |
https://chatgpt.com |
| MCP Inspector (dev tool) | http://localhost:6274/oauth/callback, http://localhost:6274/oauth/callback/debug |
http://localhost:6274 |
| Claude Code CLI | http://localhost:<ephemeral-port>/callback โ covered by the localhost exception, no entry needed |
โ (no browser) |
| Open WebUI (self-hosted) | https://<your-openwebui-host>/oauth/oidc/callback |
https://<your-openwebui-host> |
Notes
- Entries in
mcpAllowedRedirectUrisare matched by prefix, so e.g.https://claude.ai/covers any sub-path Claude may send (seeAuthorizationEndpoint::validateRedirectUri). - In a development context (non-production
TYPO3_CONTEXT) an empty allowlist permits anyredirect_uri/ origin. In production an empty allowlist restricts to localhost-only redirect URIs and same-origin requests. mcpAllowedOriginsonly affects browser-based clients (CORS). CLI and desktop-native clients ignore it.
Write modes
mcpWriteMode controls how every write-capable tool (writeRecords, copyRecords, moveRecords, localizeRecord, deleteRecords, savePageTree, โฆ) persists its changes. It can be set globally in the extension configuration and overridden per token at issue time (token-bound workspaces always win).
| Mode | What happens | When to use it |
|---|---|---|
auto (default) |
If EXT:workspaces is loaded, writes go to the BE user's default workspace; if the user hasn't picked one, the first accessible non-live workspace is used; otherwise live. | The safe default โ workspaces stay workspaces, plain installs keep working. |
workspace |
Forces every write into the BE user's workspace (be_users.workspace_id). Fails the request if the user has no workspace access. |
Editorial environments where AI changes must always go through review. |
live |
Bypasses workspaces entirely and writes live records. | Small sites without workspaces, or low-stakes automation where review isn't worth the friction. |
Resolution order (see AiSuiteMcpEndpoint):
- Token-bound workspace (set when issuing the token) โ always wins.
mcpWriteMode = liveโ live (0).mcpWriteMode = workspaceโ BE user's default workspace.mcpWriteMode = auto+ext:workspacesloaded โ user's default, falling back to the first accessible non-live workspace.- Otherwise โ live.
Read tools transparently follow whatever workspace the request resolved to โ so previews show what the model would see after the write lands.
Connectors
Each supported MCP client has its own dedicated setup guide under Connectors/. The guides cover prerequisites (extension settings, BE-group permissions, host reachability), the per-client UI / CLI / config-file steps to register the connector, smoke-test prompts, and a troubleshooting matrix.
| Client | Setup guide | Auth flow | Reach |
|---|---|---|---|
| Claude Desktop | Connectors/claude-desktop.md |
Static bearer token (default) or OAuth 2.1 | Local โ can reach localhost, *.ddev.site, internal hosts |
| Claude.ai (web) | Connectors/claude-ai.md |
OAuth 2.1 with DCR | Public HTTPS only โ Anthropic-hosted |
| ChatGPT | Connectors/chatgpt.md |
OAuth 2.1 with DCR | Public HTTPS only โ OpenAI-hosted |
| Claude Code (CLI) | Connectors/claude-code.md |
Static bearer token or OAuth 2.1 (localhost callback) | Local โ can reach private hosts |
| MCP Inspector | Connectors/mcp-inspector.md |
OAuth 2.1 (localhost:6274 callback) | Local debug tool, browser-based |
| Open WebUI (self-hosted) | Connectors/openwebui.md |
OAuth 2.1 with DCR | Wherever your OpenWebUI lives |
For a quick reference of the OAuth redirect_uri and browser origin values each client expects, see the Known MCP client callback URLs table above.
Connector setup essentials
The per-client guides under Connectors/ all share a few foundational requirements and common failure modes. They are documented once here to avoid repetition; each connector guide cross-references this section.
BE-group permissions
The TYPO3 backend user the token / OAuth consent is issued for needs the following feature flags on their BE group:
enable_mcp_accessโ mandatory; required for themcp:managescope (token / dashboard access)enable_metadata_generationโ forgenerateMetadata,batchGenerateMetadata,generateFileMetadata, โฆenable_translationโ for all translation toolsenable_image_generationโ forgenerateImageenable_content_element_generationโ forgenerateContentenable_pages_generationโ forgeneratePageTree,generateLandingPageenable_massaction_generationโ for batch / background-task toolsenable_translation_deepl_syncโ for DeepL glossary sync (mcp:glossaryscope)enable_rte_aieasylanguagepluginโ for the Easy Language tool (mcp:easy-languagescope)
Without enable_mcp_access the connector connects but every tool call returns "no permission". Without the feature-specific flags the affected tools simply don't appear in the model's tool list.
Common troubleshooting
Issues that can happen with any client, regardless of transport:
| Symptom | Cause | Fix |
|---|---|---|
MCP responds with "state parameter is required and must be at least 32 characters" during the OAuth flow |
Historical 32-character minimum on the OAuth state parameter |
In AuthorizationEndpoint.php, change < 32 to < 22 (OAuth 2.1 BCP / RFC 9700 ยง4.7) โ applies to any OAuth client whose default state length is below 32 |
MCP responds with "ArgumentCountError: Too few arguments to RateLimiter::__construct" |
DI container cache is stale after a code update to the RateLimiter class |
Flush the TYPO3 cache + DI container cache (typically by removing the generated DI container under var/cache/code/di/ and clearing caches in the backend) |
Persistent 401 on /aisuite-mcp after a fresh token, with the request reaching PHP |
Apache + mod_php / FCGI strips the Authorization header before it reaches PHP. Token endpoints still work (they read the body); the MCP endpoint requires the Bearer header and never sees it |
Add the rewrite rule to the web-root .htaccess: RewriteCond %{HTTP:Authorization} ^(.*) / RewriteRule .* - [E=HTTP_AUTHORIZATION:%1] (TYPO3's default .htaccess ships this โ verify it has not been removed) |
| Tools list is empty after a successful connect | The BE user has no AI Suite feature permissions, so all scope filtering returns empty | Grant enable_mcp_access plus the relevant feature permissions on the BE group (see BE-group permissions above), then re-authenticate from the connector |
Connector reports auth / connection failure after a successful OAuth dance, and the webserver access log shows 404 on a path like /<site-prefix>/aisuite-mcp |
The connector URL contains a TYPO3 site prefix. McpServerMiddleware only matches /aisuite-mcp at the domain root, so requests with a prefix fall through TYPO3 routing and 404. Editors are often more affected than admins, because the backend URL they see already contains the site prefix and they paste that into the connector |
Re-create the connector with the root URL (no site prefix): <host>/aisuite-mcp |
Connector misbehaves (401 / 404 / no response), but var/log/aisuite_mcp.log has no entry for the request |
The request never reached the MCP middleware at all โ the dedicated log only records requests that hit McpServerMiddleware |
Inspect the webserver access log for the actual URL that was hit. Typical root causes: site prefix in the connector URL (see previous row), enableMcp = 0 (returns a generic 404 mcp_disabled without writing to the MCP log), TLS / firewall rejection at the webserver layer |
401 on every MCP / OAuth request, with no entry in aisuite_mcp.log |
The site is behind HTTP Basic Auth (.htaccess). Basic Auth and the MCP Bearer token share the Authorization header, so the webserver rejects the request before PHP runs |
Carve the MCP paths out of Basic Auth โ see Systems behind HTTP Basic Auth (.htaccess) |
External connector (claude.ai / ChatGPT) reports "Couldn't register with โฆ sign-in service", and curl shows /.well-known/oauth-* returning 403 while /aisuite-mcp works |
The site is behind an HTTP Basic Auth / env-flag guard (e.g. Deny from env=SECURED) that catches dot-paths. The client cannot complete OAuth discovery, so dynamic client registration fails before it starts |
Exempt the discovery + MCP paths from the guard, keyed on %{THE_REQUEST} โ see Systems behind HTTP Basic Auth (.htaccess), step 2 |
Calling tools manually
When using a debug client like the MCP Inspector, tools can be invoked directly with hand-built JSON arguments instead of going through an LLM. The right-hand pane shows the raw JSON-RPC request and response for every call โ invaluable for diagnosing schema mismatches and permission issues.
A useful starter sequence:
| Tool | Arguments | Expected result |
|---|---|---|
getServerInfo |
(none) | JSON with TYPO3 version, AI Suite version, MCP version |
getTables |
(none) | List of accessible TYPO3 tables for the BE user |
getPageTree |
{ "rootPageId": 0, "depth": 2 } |
Nested JSON of the page tree |
generateMetadata |
{ "pageId": 1, "preview": true } |
Preview payload, requires explicit confirmation before write |
OAuth scopes
Each tool requires a scope, and each scope is only granted to users whose BE group has at least one of the matching AI Suite feature flags. See McpPermissionService::SCOPE_PERMISSION_MAP.
| Scope | Required BE-group permission(s) | Covers |
|---|---|---|
mcp:read |
none (baseline) | All read-only / discovery tools |
mcp:write |
none (preview + explicit confirmation is enforced per tool) | Record CRUD via DataHandler |
mcp:generate |
enable_metadata_generation, enable_content_element_generation, enable_pages_generation |
AI content / metadata / page-tree / landing-page generation |
mcp:translate |
enable_translation |
All translation tools |
mcp:image |
enable_image_generation |
AI image generation |
mcp:workflow |
enable_massaction_generation |
Batch / background task tools |
mcp:glossary |
enable_translation + enable_translation_deepl_sync |
DeepL glossary sync |
mcp:easy-language |
enable_rte_aieasylanguageplugin |
Easy Language writing |
mcp:manage |
enable_mcp_access |

|---|---|
uploadMedia |
Upload one or more existing images/videos into FAL โ by remote http(s) URL (downloaded), inline base64 (content), or a YouTube/Vimeo link (stored as an online-media reference). No AI, no credits. |
uploadMedia takes a media array; each item carries exactly one source (url or content) plus optional fileName, targetFolder and metadata (title, alternative, description). Items are processed independently โ one failing item does not abort the batch.
Security. Remote URL fetching is the sensitive part and is SSRF-guarded by RemoteMediaService: only http/https, every resolved IP must be public (private, loopback, link-local incl. the 169.254.169.254 cloud-metadata endpoint, and reserved ranges are rejected, IPv4 + IPv6), redirects are followed manually and re-validated per hop, and the download is streamed with a hard size cap. Blocked targets are logged at WARNING. Beyond the OAuth scope + enable_mcp_media_upload flag, FAL filemount permissions on the target folder still apply. Tunables (ext_conf): mcpMediaDefaultFolder, mcpMediaMaxSizeMb, mcpMediaAllowedExtensions (SVG excluded by default โ XSS), mcpMediaAllowUrlFetch (kill-switch for URL downloads), mcpMediaHostDenylist. Large videos should be supplied via url or an online-media link rather than base64.
Workflow (mcp:workflow / mcp:generate)
Batch tools run asynchronously and return a task ID. Poll via getTaskStatus, retrieve results via getTaskResults.
| Tool | Purpose |
|---|---|
batchGenerateMetadata |
Page metadata in bulk |
batchGenerateFileMetadata |
File metadata for an explicit list of files |
batchGenerateFolderMetadata |
File metadata for every file in a folder |
batchTranslatePage |

Translate file metadata for an explicit list of files |
batchTranslateFolderMetadata |
Translate file metadata for every file in a folder |
getTaskStatus |
Status of a background task |
getTaskResults |
Fetch paginated results (for translations: pass apply: true to persist) |
Operating guidelines
The server advertises a strict two-approach flow to clients (see OperatingGuidelines.php):
- External AI-powered tools (
generate*,translate*,optimize*) โ first call returns available models; second call returns a preview; client must display the preview, obtain explicit user approval, then persist viawriteRecords. - Manual tools โ discover fields via
getRecordSchema/getContentTypes/getColumnPositions; never guess; always preview + confirm beforewriteRecords.
Batch tools never auto-persist: results are suggestions that require user approval.
Custom tools
Need a tool that doesn't exist yet โ pulling data from a project-specific table, kicking off a domain workflow, exposing a sitepackage helper to the model? You can extend the MCP server from your own extension.
Anatomy of a tool
Every tool implements AutoDudes\AiSuiteMcp\Mcp\ToolInterface:
public function getName(): string; // unique tool name, used by the LLM public function getDescription(): string; // shown to the model when picking tools public function getSchema(): array; // JSON Schema for the input arguments public function execute(array $params): CallToolResult; public function getRequiredScope(): ?string; // null = no scope check
ToolInterface carries #[AutoconfigureTag('aisuite.mcp.tool')], so any service implementing it is picked up automatically by ToolRegistry โ no manual Services.yaml wiring needed, just make sure your extension's Configuration/Services.php autowires + autoconfigures the namespace.
Trust boundary
ToolRegistry::validateToolOrigin() enforces a hard rule:
- Tools under
AutoDudes\AiSuiteMcp\Mcp\Tool\may extendAbstractTooldirectly (full backend access, full DataHandler). - Tools under any other namespace must extend
AbstractCustomToolโ itsfinal doExecute()routes calls through the AI Suite Server so credit accounting and the central security policy stay in place.
Third-party tools that try to extend AbstractTool directly are silently rejected at boot time and logged as a warning to aisuite_mcp.log. Don't bypass this โ it's there to prevent custom code from siphoning AI provider calls outside the credits pipeline.
โ ๏ธ Status:
AbstractCustomToolis the planned public extension API and currently a stub (Classes/Mcp/CustomTool/). Until it ships, third-party tools cannot register. If you have a use case that doesn't fit any of the built-in tools, open a feedback issue โ we'd like to know what shape the API needs to take before we freeze it.
Adding a tool inside this extension
For tools that legitimately belong here (built-in tools), the pattern is:
- Create a class under
Classes/Mcp/Tool/<Category>/MyNewTool.phpextendingAbstractTool(orAbstractAiTool/AbstractTranslateToolfor AI-powered tools that need credit accounting and model routing). - Add
#[AutoconfigureTag('aisuite.mcp.tool')]if your class doesn't pick it up viaToolInterface(in practice it does automatically). - Implement
getName(),getDescription(),getSchema(),getRequiredScope(), anddoExecute()โ neverexecute(), which isfinalonAbstractTooland runs the validation / permissions / error-handling pipeline. - Inject any extra services through your own constructor; the bundled context (
McpToolContext) already covers the common ones (McpUserContext,McpPermissionService, logger,LocalizationService,BackendUserService, โฆ). - Map your scope to the right BE-group flag in
McpPermissionService::SCOPE_PERMISSION_MAPif you introduce a new scope.
Run the test suite (phpunit -c Tests/UnitTests.xml, phpunit -c Tests/FunctionalTests.xml) and verify the tool shows up in getServerInfo and on a connector smoke test.
Console commands
# Create a test token (bypasses OAuth flow โ development only) vendor/bin/typo3 ai-suite-mcp:create-token --user=1 vendor/bin/typo3 ai-suite-mcp:create-token --user=admin --scopes="mcp:read mcp:write mcp:generate" vendor/bin/typo3 ai-suite-mcp:create-token --user=1 --client=mcp-inspector # Clean up expired OAuth state, session files and completed task files vendor/bin/typo3 ai-suite-mcp:cleanup # Run a local MCP server over stdio (trusted local CLI clients only โ see "Local stdio transport") vendor/bin/typo3 ai-suite-mcp:server --user=1 vendor/bin/typo3 ai-suite-mcp:server --user=editor --scopes="mcp:read mcp:write"
ai-suite-mcp:cleanup removes:
- authorization codes older than 10 min
- access tokens older than the token lifetime + 7-day buffer (37 days by default)
- session files under
var/aisuite_mcp_sessions/older than 7 days - background task files under
var/mcp_tasks/older than 30 days
Schedule it via the TYPO3 Scheduler or cron.
Local stdio transport
ai-suite-mcp:server exposes the same tools as the HTTP endpoint, but over stdio
(JSON-RPC on stdin/stdout) instead of HTTP. It is intended for local, trusted CLI clients
(Claude Desktop / Claude Code on the same host) that prefer launching a command over an OAuth
connector.
# The client launches this command and talks JSON-RPC over the pipe: vendor/bin/typo3 ai-suite-mcp:server --user=<uid|username> # --scopes="mcp:read mcp:write โฆ" # default: all scopes the BE user is entitled to # --workspace=<uid> # default: resolved from mcpWriteMode
Example Claude Desktop / Claude Code config entry:
{
"mcpServers": {
"typo3-ai-suite": {
"command": "vendor/bin/typo3",
"args": ["ai-suite-mcp:server", "--user=1"]
}
}
}
Security model. stdio runs the tools as the given backend user with the scope + BE-group
double gate fully enforced (identical to HTTP). But because the transport is a local pipe, it
bypasses OAuth, the HTTPS gate, per-token rate limiting and the request-body cap โ those are
HTTP-surface protections. Run it only as a locally launched process, never wired to a network
socket. Anyone who can run the command can act as the chosen --user, so treat command access as
equivalent to that user's backend credentials. For remote / multi-user access, use the OAuth HTTP
endpoint instead.
Diagnostics are written to stderr (stdout is reserved for the JSON-RPC channel); tool calls are
logged to var/log/aisuite_mcp.log as usual.
Database tables
| Table | Purpose |
|---|---|
tx_aisuite_oauth_codes |
Short-lived authorization codes (PKCE challenge + redirect URI) |
tx_aisuite_oauth_tokens |
Access + refresh tokens, client metadata, last-used IP, credit usage |
tx_aisuite_oauth_consents |
Remembered per-user / per-client scope consents |
Security
Enforced by McpServerMiddleware and the OAuth endpoints:
- HTTPS required in production (localhost +
*.ddev.siteexempted; override withmcpAllowHttp=1โ not for production). - Request-body cap of 1 MB per MCP request.
- Rate limiting โ 100 requests / minute per Bearer token (responds
429withRetry-After: 60). - OAuth 2.1 with PKCE, no implicit / password grants.
- Dynamic Client Registration is permitted but constrained by
mcpAllowedClientIds/mcpAllowedRedirectUris. - Password change revokes all tokens for that BE user (
PasswordChangeHookonprocessDatamapClass). - Live backend-user status check on every request โ disabled / deleted users are rejected even if their token is still valid.

Production deployment
The settings, security gates, and connector flows above are sufficient to run the MCP server. Operating it stably in production additionally requires getting the topics in this section right โ none of them are enforced by the code, but ignoring any one of them tends to cause silent failures (lost session state, stale tokens, audit-log gaps, โฆ) rather than loud errors.
Reverse proxy & load balancer
- HTTPS detection:
McpServerMiddleware::enforceHttps()honorsX-Forwarded-Proto: httpsin addition to the request scheme. If your CDN or load balancer terminates TLS and forwards plain HTTP to the origin, set this header on the proxy. - HTTPS-gate trust boundary:
X-Forwarded-Protois accepted from any upstream โ the HTTPS gate does not consult themcpTrustedProxieslist (that setting only governs audit-log IP resolution, see below). A direct client that sendsX-Forwarded-Proto: httpswould bypass the HTTPS gate. Make sure your proxy strips the header from inbound traffic before re-setting it, or restrict access to the origin to the proxy IPs only (firewall / VPC). - Client IP in audit logs: OAuth audit entries (
token issued,token revoked, โฆ) record the client IP resolved byClientIpService. By default that is the peer IP (REMOTE_ADDR), which behind a proxy is the proxy IP, not the end-user IP. SetmcpTrustedProxiesto your proxy IPs / CIDRs and the service walks theX-Forwarded-Forchain from the right, skipping trusted hops, and logs the first untrusted address (the real client). WhenmcpTrustedProxiesis empty,X-Forwarded-Foris ignored entirely โ so a client cannot spoof its IP in the audit log by sending the header itself.
Webserver setup
Apache (mod_php / FCGI): TYPO3's default .htaccess ships the Authorization-header rewrite the MCP endpoint needs. Verify the rule is intact (the exact rule is in Common troubleshooting).
Nginx (php-fpm): the equivalent rewrite is per-location in your nginx config. The MCP endpoint requires the Authorization header to be forwarded to PHP explicitly:
location ~ \.php$ { fastcgi_param HTTP_AUTHORIZATION $http_authorization; # ... your existing fastcgi_params include }
Also raise client_max_body_size to at least the MCP body cap (1 MB) plus margin for batch payloads โ 8m is a safe default.
Systems behind HTTP Basic Auth (.htaccess)
Sites are often shielded with HTTP Basic Auth (.htaccess / AuthType Basic) โ staging environments, internal instances, not-yet-launched sites, and so on. This collides with the MCP server, because Basic Auth and the MCP endpoint both use the same Authorization request header โ Basic Auth sends Authorization: Basic โฆ, while the MCP endpoint requires Authorization: Bearer <token>. A request can carry only one Authorization header, so a connector placed behind Basic Auth fails: the webserver answers 401 before PHP ever runs (the request never reaches McpServerMiddleware, so there is also no entry in aisuite_mcp.log).
You can run MCP on a Basic-Auth-protected system, but the MCP paths must be carved out. The server's own OAuth 2.1 + Bearer-token auth then provides the protection on those paths.
Which paths must be reachable without Basic Auth:
/.well-known/oauth-authorization-serverand/.well-known/oauth-protected-resourceโ OAuth discovery (RFC 8414 / 9728); the client fetches these first./aisuite-mcp/oauth/*โ the OAuth flow. The interactive login on/aisuite-mcp/oauth/authorizeis the TYPO3 backend login (the actual "log in" step), so Basic Auth must not mask it./aisuite-mcp(and sub-paths) โ the MCP endpoint itself; its Bearer-token auth already protects it (every token is bound to a concrete BE user with enforced permissions).
โ ๏ธ Do not use
<Location>/<LocationMatch>for this โ they are only valid in the server / vhost configuration. Placing them in.htaccesstriggers500 Internal Server Error(<Location> not allowed herein the Apache error log). Use theRequire expr/SetEnvIfforms below.
1. Match on %{THE_REQUEST}, not Request_URI. On TYPO3, the front-controller rewrite rewrites the request to index.php before the authorization phase runs, so SetEnvIf Request_URI โฆ / <If "%{REQUEST_URI} โฆ"> no longer see the original path and silently fail to match. %{THE_REQUEST} is the verbatim original request line (e.g. GET /.well-known/oauth-authorization-server HTTP/1.1) and stays stable across internal rewrites โ always key the exemptions off it.
In the web-root .htaccess, combine your existing Basic Auth with <RequireAny> and exempt the MCP paths via Require expr. Adjust AuthUserFile to your setup and replace your current Require valid-user line with this block:
AuthType Basic AuthName "Restricted" AuthUserFile /path/to/.htpasswd <RequireAny> Require expr %{THE_REQUEST} =~ m#\s/\.well-known/oauth-# Require expr %{THE_REQUEST} =~ m#\s/aisuite-mcp# Require valid-user </RequireAny>
A request to an MCP path matches one of the Require expr lines and passes without Basic Auth; everything else falls back to Require valid-user.
2. If the host gates access via an env flag (e.g. Deny from env=SECURED), exempt the MCP paths from that flag too. Some managed hosts (and TYPO3's own staging recipe) protect the site with a pattern like:
SetEnvIf Host staging\.example\.com$ SECURED=yes # โฆ later, inside the auth block: Order allow,deny Allow from all Deny from env=SECURED
This host-based Deny is evaluated independently of the <RequireAny> above and will still 403 the MCP/discovery paths (often only the dot-paths visibly fail, while /aisuite-mcp appears to work โ an artifact of mixing legacy Satisfy/Order/Allow/Deny with Require). Unset the flag for the MCP paths, right after it is set:
SetEnvIf Host staging\.example\.com$ SECURED=yes # Exempt OAuth discovery + MCP endpoint from the staging guard: SetEnvIfExpr "%{THE_REQUEST} =~ m#\s/(\.well-known/oauth-|aisuite-mcp)#" !SECURED
(Again THE_REQUEST, not Request_URI โ and SetEnvIfExpr because SetEnvIf cannot match THE_REQUEST.)
3. Make sure the Authorization-header rewrite is present (see Webserver setup above):
RewriteCond %{HTTP:Authorization} ^(.*) RewriteRule .* - [E=HTTP_AUTHORIZATION:%1]
TYPO3's default .htaccess ships it, but verify it survived customisation โ without it the Bearer header never reaches PHP and the MCP endpoint returns 401 even though discovery and the OAuth flow work.
The rest of the site stays behind Basic Auth; only the MCP surface is opened up, and it remains protected by OAuth. To verify, curl the discovery URLs and the endpoint:
curl -i https://<host>/.well-known/oauth-protected-resource # expect 200 JSON curl -i https://<host>/.well-known/oauth-authorization-server # expect 200 JSON curl -i https://<host>/aisuite-mcp/health # expect 200 JSON
A 403 here means an env-flag guard (step 2) or a host-level dot-path block is still catching the path; a 401 with WWW-Authenticate: Basic means the Basic-Auth exemption (step 1) is not matching โ check that it keys off THE_REQUEST.
Scheduled maintenance
ai-suite-mcp:cleanup is required in production, not optional. Run it via TYPO3 Scheduler or system cron at least hourly. It removes:
- authorization codes older than 10 min
- access tokens older than the token lifetime + 7-day buffer (37 days at default
mcpTokenLifetimeDays = 30) - revoked tokens older than 30 days โ hard-deleted from
tx_aisuite_oauth_tokensto meet GDPR right-to-erasure expectations. Soft-deleted entries (deleted = 1) are kept for 30 days so refresh-token theft detection (S24) can still recognise reuse of a rotated token; after that window the signal is moot - session files under
var/aisuite_mcp_sessions/older than 7 days - background-task files under
var/mcp_tasks/older than 30 days
Without it, the authorization-code table grows unbounded, on-disk session and task directories balloon, and revoked or expired tokens accumulate in tx_aisuite_oauth_tokens. For high-volume sites (>100 concurrent users) monitor row counts in tx_aisuite_oauth_tokens and tighten mcpTokenLifetimeDays if growth outpaces the cleanup cycle.
Logging & retention
Two dedicated log files are configured for the AutoDudes.AiSuiteMcp namespace in ext_localconf.php:
var/log/aisuite_mcp.logโ INFO+ (verbose, full trace). Useful for forensic debugging and per-request audit replay. Toggleable via themcpLogVerboseextension setting (default: on). Disable in mature production deployments to reduce I/O and PII surface โ the WARNING+ alert log stays active either way.var/log/aisuite_mcp_warnings.logโ WARNING+ only. Always active. Stays small; if it is non-empty, something is worth investigating (rate-limit hits, tool execution failures, OAuth misconfigurations). Designed for monitoring / paging โ point your log shipper ortail -Fhere in production.
What gets logged:
- OAuth events (
token issued, refreshed, revoked) with client_id, BE-user UID, and (real) client IP - MCP request method, path, status code, and the first ~300 characters of the request body โ which routinely contains user prompts, page content snippets, file metadata, etc.
- Tool execution errors with full exception traces
Outbound network egress
MCP tools that call AI providers (generate*, translate*, optimize*, generateImage) inherit the network configuration of the parent autodudes/ai-suite extension. Outbound HTTPS is required to:
- the API host(s) of every provider you have enabled in AI Suite (Anthropic, OpenAI, Mittwald AI, Midjourney, Flux, DeepL, โฆ)
- the AutoDudes credit-accounting backend, if licensed via AutoDudes
In hardened environments with strict egress firewalls, allowlist the provider hosts that are actually configured in your AI Suite settings. The MCP endpoint itself does not introduce additional outbound destinations beyond what AI Suite already uses.
