n8n-MCP

Descripción

n8n-MCP gives an AI assistant structured access to n8n node documentation, properties, operations and workflow templates. It can search nodes, validate node and workflow configurations, and, when connected to an n8n instance, create, update, test and manage workflows, executions, credentials and data tables.

It runs locally over stdio with npx n8n-mcp. Documentation tools work without credentials. Workflow management needs N8N_API_URL and N8N_API_KEY from your n8n instance. Set MCP_MODE=stdio for Claude Desktop. Anonymous telemetry is on by default and can be disabled. A hosted version also exists with a free tier. This is a community project, not made by n8n GmbH.
