salacoste/mcp-n8n-workflow-builder — reverse-engineered prompt

Build me a small MCP server for n8n so I can use Claude Desktop or Cursor to create and manage n8n workflows just by chatting. I want to be able to say things like create a webhook flow, list active workflows, inspect one workflow, update it, turn it on or off, run it, and check failed runs without digging through the n8n UI or editing raw JSON by hand.

Please support both one n8n instance and multiple environments like development, staging, and production, with a simple config file and a sensible default environment. It should also help with organizing workflows using tags and handling credentials in a safe way so secrets are not exposed in logs.

Make it feel ready to use, with clear setup instructions, example config files, examples for Claude Desktop and Cursor, and enough validation and error messages that a normal person can understand what went wrong. Add tests for the main workflow, execution, tag, and credential actions. Look up current MCP and n8n docs online if you need to.
