n8n Manager MCP Server

🇩🇪 [Deutsche Version](README_de.md)

Part of the [ellmos-ai](https://github.com/ellmos-ai) family.

MCP (Model Context Protocol) server for managing n8n workflows via AI assistants like Claude, Cursor, and Windsurf.

Directory Status

• npm package: published as n8n-manager-mcp
• Glama listing: public directory page for the ellmos-ai repo
• Enterprise DNA directory: additional public directory entry for ellmos-ai/n8n-manager-mcp
• PulseMCP listing: indexed as ellmos-ai-n8n-manager
• MCP namespace status: this repo contains server.json and mcpName metadata for io.github.ellmos-ai/n8n-manager-mcp; some ecosystem directories still expose the legacy io.github.lukisch/n8n-manager-mcp name until their indexes refresh.
• Search context: best matched by n8n MCP server, n8n workflow management MCP, AI assistant n8n workflows, and ellmos-ai n8n-manager-mcp.

Features

• 18 Tools for complete n8n workflow management
• List, create, update, delete, and activate/deactivate workflows
• Safety controls: read-only mode, backup-before-delete/update, local restore, and audit log
• Multi-server support (connect to multiple n8n instances)
• Export/Import workflows between servers
• View execution history and status
• Built-in node catalog with descriptions
• Zero dependencies on Python -- connects directly to n8n REST API

Installation

Claude Desktop

Add to claude_desktop_config.json:

{
  "mcpServers": {
    "n8n-manager": {
      "command": "npx",
      "args": ["-y", "n8n-manager-mcp"]
    }
  }
}

Claude Code

claude mcp add --scope user n8n-manager npx -y n8n-manager-mcp

Manual

npm install -g n8n-manager-mcp

Quick Start

After installation, use these commands in your AI assistant:

1. Add your n8n server:

"Add my n8n server at http://localhost:5678 with API key abc123"

1. List workflows:

"Show me all workflows on my n8n server"

1. Create a workflow:

"Create an n8n workflow that triggers on a webhook, fetches data from an API, and sends a Slack message"

1. Check executions:

"Show me the last 10 workflow executions"

Available Tools

Configuration

Server connections and safety settings are stored in ~/.n8n-manager-mcp/servers.json.

Safety defaults:

• backup_before_mutations: true saves workflow JSON before update, delete, activate/deactivate, and overwrite-restore operations.
• audit_log: true appends mutation outcomes to ~/.n8n-manager-mcp/audit.log.
• read_only: false can be enabled with n8n_set_safety_mode or N8N_MANAGER_READ_ONLY=1.
• Backups are stored under ~/.n8n-manager-mcp/backups/ and can be listed/restored with the backup tools.

Development

npm install
npm run build    # One-time build
npm run dev      # Watch mode
npm start        # Start server
npm test         # Run test suite (vitest)
npm run smoke    # Start the built MCP server and verify tool discovery

Testing

The project includes 89 tests covering URL building, server management, safety settings, backup path handling, workflow JSON construction, export/import validation, i18n language packs, and error handling.

npm test              # Run all tests
npx vitest run        # Same as above
npx vitest --watch    # Watch mode
npm run smoke         # Manual stdio MCP smoke test (requires npm run build first)

Tests are verified on Windows, macOS, and Linux. GitHub Actions additionally runs build, test, and npm package checks on Node.js 20, 22, and 24. The smoke runner starts dist/index.js through the MCP SDK client, verifies all 18 tool registrations, and calls the safe n8n_describe_nodes catalog tool without requiring n8n credentials.
