FAQ from n8n-server MCP Server

What does this server do compared to a full note‑taking app?

This server is a minimal MCP demonstration: it stores notes only in memory and provides basic CRUD via tools and resource access. It does not include search, categorization, or persistence.

What are the runtime requirements?

Node.js and npm. The server is TypeScript‑based and requires building before use.

Where are notes stored?

Notes are held in the server’s in‑memory state; they are lost when the process stops. No external database or file storage is used.

How is the server invoked?

It communicates over stdio and is launched by an MCP host (e.g., Claude Desktop) via the command path specified in claude_desktop_config.json.

Does it require authentication?

The README does not describe any authentication mechanism. It runs locally as a subprocess of the MCP host.
