This commit adds a new MCP tool, run_webhook, which allows executing n8n workflows via webhooks instead of using the API directly. This implementation:
1. Creates a new RunWebhookHandler class that:
- Takes a workflowName parameter and automatically prepends "webhook/" to create the full path
- Uses basic authentication from environment variables
- Makes HTTP requests to the webhook endpoints and returns the responses
2. Adds new environment variables:
- N8N_WEBHOOK_USERNAME: Username for webhook basic authentication
- N8N_WEBHOOK_PASSWORD: Password for webhook basic authentication
3. Updates server configuration and handlers to register and expose the new tool
4. Adds comprehensive documentation in:
- execution-tools.md with examples and schema
- README.md with configuration and usage information
This provides a simpler alternative to the API-based workflow execution, allowing Claude to trigger n8n webhooks directly.
