README

Read-only HTTP API exposing local Sulu template XML files (pages, articles, blocks, snippets, properties) for use by an MCP (Model Context Protocol) server.

What it does

Provides two authenticated endpoints mounted under the project's admin API prefix (typically /admin/api):

Method	Path	Returns
GET	/admin/api/mcp/templates/{type}	JSON list of template names available for a type
GET	/admin/api/mcp/templates/{type}/{name}	Raw XML body of a single template

Auth is handled entirely by the Sulu admin firewall: the endpoints live under /admin/api/*, so the standard admin firewall (^/admin) applies. A request without a valid admin session (cookies) is rejected with 401 before reaching the controller.

Installation

composer require alengo/sulu-mcp-server-bundle

Register the bundle in config/bundles.php:

Alengo\SuluMcpServerBundle\McpServerBundle::class => ['all' => true],

Import the routing in config/routes/alengo_mcp_server.yaml:

alengo_mcp_server:
    resource: "@McpServerBundle/Resources/config/routing_admin_api.yaml"
    prefix: /admin/api

The MCP client must send the admin session cookies obtained after authenticating against /admin/login with a Sulu admin user. The standard Sulu admin firewall (^/admin) protects the path; no PUBLIC_ACCESS exception is required in security.yaml.

Configuration

The bundle ships with sensible defaults — no configuration file is required.

To override defaults, create config/packages/alengo_mcp_server.yaml:

alengo_mcp_server:
    # Template type => directory mapping (paths relative to %kernel.project_dir%).
    template_dirs:
        page:     config/templates/pages
        article:  config/templates/articles
        block:    config/templates/blocks/content
        snippet:  config/templates/snippets
        property: config/templates/properties

You can add additional template types by extending template_dirs — the controller will resolve any configured type.

Security model

• Admin firewall. The path lives under /admin/api/*, so the standard Sulu admin firewall (^/admin) applies. Requests without a valid admin session are rejected with 401 and never reach the controller.
• Read-only. No write endpoints.

Requirements
