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

- HN Thread: https://news.ycombinator.com/item?id=43447278
- OpenAPISearch: https://github.com/janwilmake/openapisearch
- OAPIS: https://github.com/janwilmake/oapis
The MCP works by applying a 3 step process:
- It figures out the openapi identifier you need
- It requests a summary of that in simple language
- 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
Installation
For other clients, use MCP URL: https://openapi-mcp.openapisearch.com/mcp
Local testing
First run the server
wrangler dev
Then run the mcp inspector:

FAQ
- What is the OpenAPI Proxy MCP server?
- OpenAPI Proxy is a Model Context Protocol (MCP) server profile on explainx.ai. MCP lets AI hosts (e.g. Claude Desktop, Cursor) call tools and resources through a standard interface; this page summarizes categories, install hints, and community ratings.
- How do MCP servers relate to agent skills?
- Skills are reusable instruction packages (often SKILL.md); MCP servers expose live capabilities. Teams frequently combine both—skills for workflows, MCP for APIs and data. See explainx.ai/skills and explainx.ai/mcp-servers for parallel directories.
- How are reviews shown for OpenAPI Proxy?
- This profile displays 10 aggregated ratings (sample rows for discoverability plus signed-in user reviews). Average score is about 4.5 out of 5—verify behavior in your own environment before production use.

OpenAPI Proxy has been reliable for tool-calling workflows; the MCP profile page is a good permalink for internal docs.
- ★★★★★Rahul Santra· Mar 3, 2024
According to our notes, OpenAPI Proxy benefits from clear Model Context Protocol framing — fewer ambiguous “AI plugin” claims.
- ★★★★★Pratham Ware· Feb 2, 2024
We wired OpenAPI Proxy into a staging workspace; the listing’s GitHub and npm pointers saved time versus hunting across READMEs.
- ★★★★★Yash Thakker· Jan 1, 2024
