n8n-MCP

by czlonkowski

n8n-MCP turns your AI coding assistant into an n8n workflow automation expert. It bridges the Model Context Protocol with n8n's entire node ecosystem: 1,396 nodes (812 core + 584 community), 2,700+ workflow templates, and 265 AI-capable tool variants.The practical difference: before n8n-MCP, asking Claude Code to build an n8n workflow was a coin flip. The model would hallucinate node names, invent non-existent parameters, and produce workflows that failed validation. n8n-MCP eliminates that by feeding the AI comprehensive, accurate documentation for every node, operation, and property.The creator, Romuald Czlonkowski, claims it reduces workflow creation time from 45 error-prone minutes to 3 flawless minutes. That number comes from community reports, not formal benchmarks. But the architecture supports it: 99% property coverage, 87% documentation availability, and 2,646 pre-extracted real-world configurations from popular templates.How It WorksThe MCP server exposes n8n documentation as structured tools that AI assistants can query. When you ask Claude Code to "build a workflow that triggers on a new Stripe payment and sends a Slack notification," the server provides exact node configurations, credential schemas, and expression syntax. The AI does not guess. It looks up the correct parameters.A Chat Agent feature lets you describe automations in plain language and receive production-ready workflows. Diff-based updates allow modifying existing workflows without rebuilding from scratch. Real-time monitoring and auto-validation catch errors before deployment.Setup OptionsThe fastest path is the hosted dashboard at dashboard.n8n-mcp.com (free tier: 100 tool calls/day, 5 chat prompts/day). For self-hosting: npx, Docker, Railway, or local installation. The Supporter plan at 19 EUR/month gives 200 daily prompts and unlimited tool calls.Compatible AI ToolsWorks with Claude Code, Claude Desktop, Cursor, Windsurf, VS Code with GitHub Copilot, Gemini CLI, Kiro, Codex, and 15+ other AI development tools. The companion n8n-skills repository provides 7 Claude Code skills for deeper integration.LimitationsOperation coverage sits at 63.6%, meaning some node operations lack full documentationFree tier limits (100 calls/day) may be tight for heavy automation buildersCommunity nodes (584) have less reliable documentation than core nodesThe server provides documentation only. It does not execute workflows or manage n8n instances directly (use n8n-manager-for-ai-agents for that)Critical safety note from the maintainers: never edit production workflows directly with AI. Always test in development environments first and export backups before deployment.For more MCP servers, browse repos.skila.ai/servers. For AI workflow automation tools, check tools.skila.ai.
