n8n API MCP Server

Search the local API spec database for endpoints matching a query (path, summary, description, tags).

Retrieve detailed information (parameters, request body, responses) for a specific endpoint (path and method) from the local API spec database.

Execute an API call to the configured n8n instance. Checks Fast Memory first; if not found, prompts to save the call to Fast Memory upon success.

Search for API calls using natural language. Checks Fast Memory first, then falls back to searching the API spec database based on the query.

Manually save an API call (path, method, params, data) along with its original natural language query and a description to the Fast Memory database.

List entries currently stored in the Fast Memory database, optionally filtering by a search term.

Delete a specific entry from the Fast Memory database by its ID.

Remove all entries from the Fast Memory database.

Load or update the API Specification database (`api_spec.db`) by parsing an OpenAPI/Swagger JSON file.

Execute an API call using a raw request string (e.g., "GET /workflows?limit=5"). Uses the same underlying logic as `execute_api_call`, including Fast Memory checks and save prompts.
