Verified Safeby spences10
Overview
Programmatic creation and management of n8n workflows by AI assistants via the Model Context Protocol (MCP).
Installation
npx -y mcp-n8n-builderEnvironment Variables
- N8N_HOST
- N8N_API_KEY
Security Notes
The source code does not contain 'eval' or obvious obfuscation. Secrets (N8N_API_KEY) are correctly handled via environment variables. Network requests are made to a configurable n8n host. A critical functional note: The N8N_HOST environment variable configuration examples in the README are contradictory to the code's API client implementation. If N8N_HOST is set to include '/api/v1' (e.g., 'http://localhost:5678/api/v1') as per README examples, the client will incorrectly construct URLs as 'http://localhost:5678/api/v1/api/v1/...' causing API calls to fail. N8N_HOST should ideally be set without '/api/v1' (e.g., 'http://localhost:5678') as the client appends it.
