Why mcp-n8n?

Other n8n MCPs cover workflows and executions. mcp-n8n covers everything — including Data Tables, the only MCP to do so.

✨ Features

• 43 tools — the most comprehensive n8n MCP available

• Credential data is redacted in list responses (n8n API behavior)
• All IDs are sanitized with encodeURIComponent to prevent path traversal
• No sensitive data is logged or exposed in error messages
