What is the Fastn MCP Server?
Connect your Fastn account to any AI agent to orchestrate complex backend workflows and real-time API flows through natural language.
What you can do
- Flow Execution — Trigger Fastn flows instantly with custom JSON payloads and receive real-time responses via the API sync layer.
- Workflow Management — List, create, update, and publish flow definitions across different tenants to maintain your business logic.
- Execution Monitoring — Track execution history and drill down into step-by-step traces to debug or audit automated processes.
- Credential Handling — Securely store, retrieve, and rotate credentials for your various connectors and third-party integrations.
- Platform Insights — Monitor your platform usage, including daily quotas, summary metrics, and active space configurations.
How it works

Frequently asked questions
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.
How do I add an MCP server to Claude Code?
Run claude mcp add <name> --transport http "<url>" in your terminal. Claude Code registers the server and discovers all tools immediately.
Can Claude Code run MCP tools in headless mode?
Yes. Claude Code supports non-interactive execution, making it ideal for scripts, cron jobs, and CI/CD pipelines that need MCP tool access.
How do I list all connected MCP servers?
Run claude mcp in your terminal to see all registered servers and their status, or type /mcp inside an active Claude Code session.
