MCP.Pizza Chef: janwilmake

Most web services publish a long technical reference that nobody wants to read end to end. This hosted helper finds the right document, boils it down to simple language, then explains only the specific commands you asked about. It is tested with Claude Desktop and Cursor, runs on the maintainer's own servers, and needs no key and no install — you point your assistant at one web address and start asking. Coverage comes from the linked OpenAPISearch directory.

OpenAPI MCP Server

janwilmake/openapi-mcp-server context

A Model Context Protocol (MCP) server for Claude/Cursor that enables searching and exploring OpenAPI specifications through oapis.org.

The MCP works by applying a 3 step process:

  1. It figures out the openapi identifier you need
  2. It requests a summary of that in simple language
  3. It determines which endpoints you need, and checks out how exactly they work (again, in simple language)

Features

  • Get an overview of any OpenAPI specification
  • Retrieve details about specific API operations
  • Support for both JSON and YAML formats
  • Tested with Claude Desktop and Cursor

openapi-mcp-server FAQ

Which apps does this work in?
Tested with Claude Desktop and Cursor; any assistant that accepts a hosted address should work.
Do I need a key or an install?
Neither. It runs on the maintainer's servers, so you paste one address and you are finished.
Can I use this to figure out a service I have never touched before?
Yes — it locates the reference, summarises it in plain language, then walks through only the commands you need.
Which services are covered?
Whatever is listed through the linked OpenAPISearch directory, which is where it looks things up on your behalf.
How hard is setup?
The easiest kind — one hosted address, nothing to install, no account to create.
Does anything of mine get sent away?
Your questions go to the maintainer's hosted service, so treat it like any other public web tool.
