Turn an API into an MCP Tool | Free Sandbox
An MCP server on SchemaBridge is just a workflow. This template shows the shape: a request arrives on an entry point, which is the tool surface an AI agent calls, and a gateway step calls the API you already have (here, the GitHub API). On the canvas you see the same two-step topology an MCP client invokes as a tool: the entry point is the tool, the gateway is your API. Nothing runs on arrival because the point is the wiring, which you can edit, extend with more steps, and deploy as a hosted MCP server once you sign in.
How to test API to MCP Tool
This sandbox opens with a real example payload already loaded into a live workflow. Run it to watch the event move through every node, inspect the JSON at each step, and edit the mapping logic in place — no sign-up, no setup, no local tunnel. Create a free account when you are ready to point your own webhooks at a live endpoint and keep the workflows you build here.
- Start the sandbox to load a real API to MCP Tool example payload into a live workflow.
- Run the workflow and watch the event move through each node on the canvas.
- Edit the mapping, add a destination, and re-run to see your changes immediately.
