README

🚧 Under active development. This extension is in beta state and evolving fast. Tool signatures, settings keys, and the upcoming AbstractCustomTool API 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 — #ai-suite on TYPO3 Slack — 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 — and lets the model drive the same AI providers (Anthropic, OpenAI, Mittwald AI, DeepL, Midjourney, Flux, …) that AI Suite already integrates.

• Extension key: ai_suite_mcp
• Composer package: autodudes/ai-suite-mcp
• PSR-4 namespace: AutoDudes\AiSuiteMcp\ → Classes/

What you can do with it

Once connected, your MCP client can drive the TYPO3 backend the same way an editor would — but without leaving the chat.

• 🧭 Walk the page tree, read pages, search content — the model gets first-class access to every page, content element and FAL file the BE user can see.
• ✍️ Generate & optimize content — full tt_content elements, landing pages, complete page trees from a single prompt, plus rewrite / shorten / simplify on existing copy.
• 🌍 Translate anything — single records, complete pages, file metadata, or whole folders in one batch. Includes Easy Language rewrites for accessible content.
• 🏷️ Fill in metadata at scale — SEO titles, descriptions, OG / Twitter tags, alt texts, file metadata. Single record or bulk over a whole folder / page subtree.
• 🖼️ Generate images straight into FAL — the result lands as a real sys_file, ready to be referenced.
• 🧱 Edit records safely — every CRUD tool runs through DataHandler with a mandatory preview / confirm step before anything is persisted.
• 🧰 Workspace-aware writes — auto-routes changes through TYPO3 workspaces when EXT:workspaces is loaded; tokens can even be pinned to a specific workspace.
• 🧩 Works with EXT:container and your custom records — container children, third-party tables (news, products, custom CTypes) are first-class.
• ⏱️ Background batch jobs — long-running translations / metadata generation get an async task ID; results come back as suggestions you approve.
• 🔐 Production-grade auth — OAuth 2.1 + PKCE with dynamic client registration, per-token rate limiting, full HTTPS enforcement, password-change revocation.
• 👤 Respects TYPO3 BE-user permissions — 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.
• 📊 Reports + dedicated logs — 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 — 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	ChatGPT, Anthropic, Mittwald AI, Meta Llama-3.3 (70B-Instruct)
Page-tree / landing pages	generatePageTree, generateLandingPage, savePageTree	ChatGPT, Anthropic, Mittwald AI, Meta Llama-3.3 (70B-Instruct)
Translation (records, pages, file metadata)	translateRecord, translatePage, translateFileMetadata, batchTranslatePage, batchTranslate*Metadata	DeepL, Google Translate, ChatGPT, Anthropic, Mittwald AI
Easy Language (accessibility rewrites)	exposed via optimizeContent / translation tools	ChatGPT, Anthropic, Meta Llama-3.3 (70B-Instruct)
DeepL glossary sync	(via AI Suite — gated by mcp:glossary scope)	DeepL
Image generation	generateImage	DALL·E / GPT-Image (OpenAI), Midjourney, Flux

The exact model list available to a given BE user depends on the AI-model permissions configured on their BE group in AI Suite. The model picks itself up automatically from the AI Suite settings — no extra config in MCP.

Requirements

• TYPO3 12.4.11 – 14.3.1
• PHP 8.2+
• autodudes/ai-suite ^12.19 | ^13.13 | ^14.1
• typo3/cms-reports
• logiscape/mcp-sdk-php ^1.2

Installation

composer require autodudes/ai-suite-mcp
vendor/bin/typo3 extension:setup

Configuration

All settings live under Admin Tools → Settings → Extension Configuration → 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 — Bearer tokens would travel in clear text. Localhost and *.ddev.site are always exempted from HTTPS enforcement.
mcpWriteMode	auto	How write tools persist data — 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 — use to hide sensitive tables (e.g. be_users, fe_users, sys_log) from MCP clients regardless of the user's TYPO3 role.

Known MCP client callback URLs

Copy these into mcpAllowedRedirectUris / mcpAllowedOrigins for every client you want to support.

Client	redirect_uri → mcpAllowedRedirectUris	Browser origin → 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 — covered by the localhost exception, no entry needed	— (no browser)
Open WebUI (self-hosted)	https://<your-openwebui-host>/oauth/oidc/callback	https://<your-openwebui-host>

Notes

• Entries in mcpAllowedRedirectUris are matched by prefix, so e.g. https://claude.ai/ covers any sub-path Claude may send (see AuthorizationEndpoint::validateRedirectUri).
• In a development context (non-production TYPO3_CONTEXT) an empty allowlist permits any redirect_uri / origin. In production an empty allowlist restricts to localhost-only redirect URIs and same-origin requests.
• mcpAllowedOrigins only affects browser-based clients (CORS). CLI and desktop-native clients ignore it.

Write modes

mcpWriteMode controls how every write-capable tool (writeRecords, copyRecord, moveRecord, localizeRecord, deleteRecords, savePageTree, …) 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 — 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):

1. Token-bound workspace (set when issuing the token) — always wins.
2. mcpWriteMode = live → live (0).
3. mcpWriteMode = workspace → BE user's default workspace.
4. mcpWriteMode = auto + ext:workspaces loaded → user's default, falling back to the first accessible non-live workspace.
5. Otherwise → live.

Read tools transparently follow whatever workspace the request resolved to — 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 — can reach localhost, *.ddev.site, internal hosts
Claude.ai (web)	Connectors/claude-ai.md	OAuth 2.1 with DCR	Public HTTPS only — Anthropic-hosted
ChatGPT	Connectors/chatgpt.md	OAuth 2.1 with DCR	Public HTTPS only — OpenAI-hosted
Claude Code (CLI)	Connectors/claude-code.md	Static bearer token or OAuth 2.1 (localhost callback)	Local — 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_access — mandatory; required for the mcp:manage scope (token / dashboard access)
• enable_metadata_generation — for generateMetadata, batchGenerateMetadata, generateFileMetadata, …
• enable_translation — for all translation tools
• enable_image_generation — for generateImage
• enable_content_element_generation — for generateContent
• enable_pages_generation — for generatePageTree, generateLandingPage
• enable_massaction_generation — for batch / background-task tools
• enable_translation_deepl_sync — for DeepL glossary sync (mcp:glossary scope)
• enable_rte_aieasylanguageplugin — for the Easy Language tool (mcp:easy-language scope)

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 §4.7) — 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 — 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 — 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

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 — 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	Global instructions, prompt templates, token / dashboard access

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):

1. External AI-powered tools (generate*, translate*, optimize*) — first call returns available models; second call returns a preview; client must display the preview, obtain explicit user approval, then persist via writeRecords.
2. Manual tools — discover fields via getRecordSchema / getContentTypes / getColumnPositions; never guess; always preview + confirm before writeRecords.

Batch tools never auto-persist: results are suggestions that require user approval.

Custom tools

Need a tool that doesn't exist yet — 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 — 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 extend AbstractTool directly (full backend access, full DataHandler).
• Tools under any other namespace must extend AbstractCustomTool — its final 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 — it's there to prevent custom code from siphoning AI provider calls outside the credits pipeline.

⚠️ Status: AbstractCustomTool is 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 — 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:

1. Create a class under Classes/Mcp/Tool/<Category>/MyNewTool.php extending AbstractTool (or AbstractAiTool / AbstractTranslateTool for AI-powered tools that need credit accounting and model routing).
2. Add #[AutoconfigureTag('aisuite.mcp.tool')] if your class doesn't pick it up via ToolInterface (in practice it does automatically).
3. Implement getName(), getDescription(), getSchema(), getRequiredScope(), and doExecute() — never execute(), which is final on AbstractTool and runs the validation / permissions / error-handling pipeline.
4. Inject any extra services through your own constructor; the bundled context (McpToolContext) already covers the common ones (McpUserContext, McpPermissionService, logger, LocalizationService, BackendUserService, …).
5. Map your scope to the right BE-group flag in McpPermissionService::SCOPE_PERMISSION_MAP if 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 — 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

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.

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.site exempted; override with mcpAllowHttp=1 — not for production).
• Request-body cap of 1 MB per MCP request.
• Rate limiting — 100 requests / minute per Bearer token (responds 429 with Retry-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 (PasswordChangeHook on processDatamapClass).
• Live backend-user status check on every request — disabled / deleted users are rejected even if their token is still valid.
• Scope + permission double check — an OAuth scope alone is not sufficient; the BE user group must also carry the matching AI Suite feature flag.
• Reports module surfaces misconfigurations: HTTP allowed, empty allowlists in production. Check System → Reports → AI Suite MCP Security.

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 — 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, …) rather than loud errors.

Reverse proxy & load balancer

• HTTPS detection: McpServerMiddleware::enforceHttps() honors X-Forwarded-Proto: https in 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.
• Trust boundary: the header is currently accepted from any upstream — the middleware does not maintain a trusted-proxy list. A direct client that sends X-Forwarded-Proto: https would 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, …) record $_SERVER['REMOTE_ADDR'], which behind a proxy is the proxy IP, not the end-user IP. X-Forwarded-For is currently not parsed; if real client IPs in the audit log matter for compliance, that is a code change, not a setting.

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 — 8m is a safe default.

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 — hard-deleted from tx_aisuite_oauth_tokens to 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.log — INFO+ (verbose, full trace). Useful for forensic debugging and per-request audit replay. Toggleable via the mcpLogVerbose extension setting (default: on). Disable in mature production deployments to reduce I/O and PII surface — the WARNING+ alert log stays active either way.
• var/log/aisuite_mcp_warnings.log — 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 — point your log shipper or tail -F here 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 — 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, …)
• 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.

Feedback

We're actively shaping this extension and the upcoming public custom-tool API. If you try it out — especially against a real editorial workflow — we'd love to hear from you:

• 🐛 Bugs / regressions → please file an issue with the relevant aisuite_mcp_warnings.log excerpt and the connector you used.
• 💡 Tool gaps → if you reached for a tool that doesn't exist (a third-party table you'd like discoverable, a workflow not covered by the built-ins), tell us what the LLM should have been able to do. This is the most valuable feedback for the AbstractCustomTool API design.
• 🔌 New connectors → if your favourite MCP client isn't in Connectors/, share the redirect URI / origin / auth flow it expects and we'll add a guide.
• 🔒 Security findings → please contact us directly rather than opening a public issue.

The fastest way to reach us is the #ai-suite channel on TYPO3 Slack. You can also reach us via [e-mail].
