Enables GitHub OAuth authentication for APIs, allowing the MCP server to turn any API into a GitHub OAuth Client & Provider.
Transforms serverless server handlers into MCP endpoints, allowing serverless functions to be exposed as MCP-compatible APIs.
Click on "Deploy Server".
Wait a few minutes for the server to deploy. Once ready, it will show a "Started" state.
In the chat, type
@followed by the MCP server name and your instructions, e.g., "@With-MCPconvert my OpenAPI spec for the user management API into an MCP endpoint"
That's it! The server will respond to your query, and you can continue using it as needed.
Here is a step-by-step guide with screenshots.
A simple middleware that turns your serverless server handler + OpenAPI spec + config into a exposed MCP endpoint following the new stateless MCP principles
See example for how to use this.

Disclaimer: Please only use this for APIs that are compliant to the MCP Authorization spec, or have no authorization. Also follow good MCP practices for choosing how to shape your tools, prompts, and resources. Do NOT Blindly turn a complex API into an MCP, this is a bad idea.
Work in progress: I'm working on a simpler auth plugin for your handler as well to turn any API into a GitHub Oauth Client & Provider. Eventually it will be MCP compatible. See library here
