n8n Manager for AI Agents

A Model Context Protocol (MCP) server that enables Claude Desktop and other AI agents to manage n8n workflow automation instances through the n8n API.

This MCP server provides AI agents with tools to manage n8n workflows programmatically. It implements the core n8n API operations with intelligent workarounds for API limitations.

- Workflow Management: Create, read, update, and delete workflows
- Execution Monitoring: List and view execution details, delete execution records
- Webhook Triggers: Execute workflows via webhook endpoints
- Health Monitoring: Check n8n instance connectivity and configuration

- Workflow Activation: Cannot activate/deactivate workflows via API (manual UI activation required)
- Direct Execution: Not available - must use webhook triggers
- Tags & Credentials: Read-only fields, cannot be set via API

- Workflow Operations: Full CRUD operations for n8n workflows
- Execution Management: View, list, and delete execution records
- Webhook-Based Execution: Trigger workflows via webhook URLs
- Smart Error Handling: Automatic removal of read-only fields, method fallbacks
- AI-Friendly Descriptions: Enhanced tool descriptions with examples and clear limitations
- Cursor-Based Pagination: Efficient handling of large result sets
- Health Monitoring: Built-in connectivity and configuration checks

- Workflow Activation: Theactivefield is read-only - workflows must be activated manually in the UI
- Tags Field: Read-only during creation and updates
- PATCH Method: Some n8n instances don't support PATCH for workflow updates
- Direct Execution: Must use webhook triggers (no direct execution API)
- Settings Field: Required but undocumented - we provide sensible defaults

- User Management: No public API endpoints
- Credential Management: Limited API, schemas not exposed
- Stop Execution: Cannot stop running executions via API
- Variables: Only available through source control API
- Import/Export: Planned but not yet implemented
