Frequently asked questions about the Fastn MCP Server

Can I trigger a flow and get the result immediately?

Yes. Use the execute_flow tool with the flow name and input data. It performs a real-time sync execution and returns the response directly to the agent.

How can I debug a failed flow execution?

You can use list_executions to find the ID of the failed run, then use get_execution to retrieve a full step-by-step trace of what happened during that specific execution.

Is it possible to update an existing workflow definition?

Absolutely. The update_workflow tool allows you to modify the JSON definition of any flow. Remember to use publish_workflow afterwards to deploy your changes to the live environment.
