n8n instance-level MCP server

Was er kann

The MCP server built into n8n itself. An instance owner or admin switches it on under Settings, and any MCP client can then connect over HTTP to the instance's /mcp-server/http address, signing in with OAuth or a personal access token. Through it an assistant can look up workflows, run the ones that have been made available to MCP, and, on recent n8n 2.x versions, build and edit workflows and data tables. Workflows are not exposed by default; each one, or a whole project or folder, has to be enabled first, and every connected client sees the same set. Self-hosted instances can turn the feature off entirely.
