n8n-MCP

A Model Context Protocol (MCP) server that provides AI assistants with comprehensive access to n8n node documentation, properties, and operations. Deploy in minutes to give Claude and other AI assistants deep knowledge about n8n's 3,135 workflow automation nodes (840 core + 2,295 community).

Overview

n8n-MCP serves as a bridge between n8n's workflow automation platform and AI models, enabling them to understand and work with n8n nodes effectively. It provides structured access to:

• 3,135 n8n nodes - 840 core nodes + 2,295 community nodes (1,878 verified) • Node properties - 99% coverage with detailed schemas • Node operations - 66.5% coverage of available actions • Documentation - 86% coverage from official n8n docs (including AI nodes) • AI tools - 267 AI-capable tool variants detected with full documentation • Real-world examples - 156 ranked configurations extracted from popular templates • Template library - 2,352 workflow templates with 99.96% AI metadata coverage • Community nodes - Search verified community integrations with source filter

Support This Project

n8n-mcp started as a personal tool but now helps tens of thousands of developers automate their workflows efficiently. Maintaining and developing this project competes with my paid work. Your sponsorship helps me dedicate focused time to new features, respond quickly to issues, keep documentation up-to-date, and ensure compatibility with latest n8n releases. Become a sponsor

Important Safety Warning

NEVER edit your production workflows directly with AI! Always: • Make a copy of your workflow before using AI tools • Test in development environment first • Export backups of important workflows • Validate changes before deploying to production

AI results can be unpredictable. Protect your work!

Quick Start

The fastest way to try n8n-MCP - no installation, no configuration:

Cloudflare Access Authentication

If your n8n instance sits behind Cloudflare Access (Zero Trust), provide your service token so n8n-MCP can authenticate:

• N8N_CF_CLIENT_ID - Cloudflare Access Client ID • N8N_CF_CLIENT_SECRET - Cloudflare Access Client Secret

When set, these are sent as CF-Access-Client-Id / CF-Access-Client-Secret headers on n8n API requests, version/health probes, and webhook executions. The token is confined to the N8N_API_URL origin — webhook calls to a different host (e.g. a split WEBHOOK_URL origin) do not receive it, to avoid leaking the token.

n8n Agents and Instance-Level MCP (Optional)

To use n8n_manage_agents, n8n_explore_node_resources, and the project fallback in n8n_list_catalog, set:

• N8N_MCP_ACCESS_TOKEN - MCP API key from n8n Settings → Instance-level MCP → set MCP status to Enabled. This is a separate secret from N8N_API_KEY and should be stored the same way. The MCP endpoint is derived from N8N_API_URL; instances that serve MCP from a split host (N8N_MCP_BASE_URL) are not supported.

See Connecting n8n-mcp to n8n's instance-level MCP server for the full setup walkthrough, including how to get the token from the n8n UI, prerequisites, and troubleshooting.

Claude Project Setup

For the best results when using n8n-MCP with Claude Projects, use these enhanced system instructions:

json // FAILS at runtime {resource: "message", operation: "post", text: "Hello"}

// WORKS - all parameters explicit {resource: "message", operation: "post", select: "channel", channelId: "C123", text: "Hello"}

[Silent tool execution in parallel]

Created workflow: • Webhook trigger → Slack notification • Configured: POST /webhook → #general channel

Validation: All checks passed

[Silent tool execution]

Updated workflow: • Added error handling to HTTP node • Fixed required Slack parameters…
