Configure TYPO3 MCP via STDIO

Copy-paste prompt​

Set up TYPO3 MCP for my mittwald TYPO3 app using STDIO transport.

Tasks:
1) identify the correct TYPO3 installation ID,
2) verify TYPO3 MCP server package availability,
3) provide a working local command and MCP config block,
4) explain current runtime limitations before execution.

Ask before changing dependencies or running write operations.

Prerequisites​

  • A TYPO3 installation running on mittwald
  • Local access to the mw CLI
  • TYPO3 MCP server package hn/typo3-mcp-server installed in the TYPO3 instance

Local STDIO transport command​

Use mw app exec to run the TYPO3 MCP server inside your app container:

user@local $ mw app exec --quiet --installation-id=a-XXXXX "vendor/bin/typo3 mcp:server"

Replace a-XXXXX with your TYPO3 app installation ID.

Find the installation ID​

List app installations and pick the TYPO3 installation ID:

user@local $ mw app list

Use the returned ID in --installation-id=....

Composer dependency note​

If vendor/bin/typo3 mcp:server is not available, install the package inside the TYPO3 installation:

user@local $ mw app exec --installation-id=a-XXXXX "composer require hn/typo3-mcp-server"

MCP configuration example​

Use this command-based server configuration in MCP-capable tools:

{
  "mcpServers": {
    "typo3": {
      "command": "mw",
      "args": [
        "app",
        "exec",
        "--quiet",
        "--installation-id=a-XXXXX",
        "vendor/bin/typo3 mcp:server"
      ]
    }
  }
}
