# n8n API Limitation: Schedule Triggers Not Testable via API
|
|
|
|
## Observation
|
|
The n8n MCP `n8n_test_workflow` tool (and the underlying n8n API) only works with externally-triggerable workflows. 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)
