Why people use Fastn
Fastn for Debugging Complex Backend Workflows
This Connector changes that. You stay in your editor and just tell your agent to run the flow. If it hits a snag, you ask for the trace. You get the answer immediately without ever leaving your workspace.
What Vinkius changes
You get a natural language interface for your entire Fastn backend.
Use it from Claude, ChatGPT, Cursor or another AI client you already have.

Before you connect
Questions about Fastn.
The practical details behind the request, access and result.
Can the Fastn MCP run my backend flows using natural language?
Yes. You can tell your agent to trigger specific flows by describing the action or providing the necessary data. It handles the API communication for you.
How does the Fastn MCP help with debugging?
It allows your agent to pull detailed, step-by-step execution traces. You can ask why a specific run failed and get a breakdown of every step instantly.
Is it safe to manage API keys with the Fastn MCP?
Yes. The Connector includes capabilities to store and rotate credentials securely. This keeps your secrets out of your prompts and your agent's conversation history.
Can I use Fastn MCP to see my platform usage?
Absolutely. You can ask your agent for a summary of your usage, your daily breakdown, or your current plan limits without leaving your chat.
Does Fastn MCP support deploying new flows?
Yes. You can use the agent to publish new flow definitions to your production environment or archive old ones to keep your backend organized.
Can I stop a flow that is currently hanging?
Yes. If a process is stuck, you can ask your agent to cancel the execution immediately to free up your resources.
Can I trigger a flow and get the result immediately?
Yes. Use the execute_flow capability 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 capability allows you to modify the JSON definition of any flow. Remember to use publish_workflow afterwards to deploy your changes to the live environment.
