Supported trigger types: +- Webhook +- Form +- Chat + +## Limitation +Schedule-triggered workflows (e.g., cron, interval) **cannot** be executed on-demand via the API or MCP tools. + +## Workarounds +- Wait for the next scheduled run +- Manually test the SSH command chain outside n8n +- Temporarily add a webhook trigger node to test, then remove it +- Use the n8n UI "Execute Workflow" button (manual run from the editor)
