Generate an MCP server from what you already have
Start free with your API, documentation, website or files. InstantMCP.io turns your source into a hosted MCP endpoint that AI clients can use.
Your source already explains the product. Let it define the tools.
Building an MCP server from scratch usually means translating routes, schemas and documentation into a second interface. That work is important, but it should not delay the first useful connection.
InstantMCP.io reads the source you choose, extracts the structure agents need and creates a working MCP server without asking you to maintain another adapter repository. Start with the free workflow, then refine the result as your product evolves.
The result is a real endpoint for Claude, Cursor, ChatGPT, Windsurf and other MCP-compatible clients. You get a practical first version quickly, with a path to production when usage grows.
A useful MCP foundation without the setup tax.
The free generator is designed to prove the value of your source, not hide the important details behind a demo.
Source-aware generation
Turn the structure in your docs, API or files into tool definitions that agents can understand.
Preview before connecting
Review the generated surface before you paste an endpoint into Claude, Cursor or another client.
A live endpoint
Move from an idea to a reachable MCP URL without provisioning a separate server first.
From source to first tool in a few focused steps.
Keep the first experiment small, then expand it when the use case proves itself.
