This is a gateway to APIs.guru's collection of 2,500+ public API specifications, all available without API keys. It gives Claude direct access to OpenAPI specs from hundreds of services, which means you can query metadata about REST APIs, discover endpoints, or pull schema definitions on the fly. The Pipeworx implementation adds an ask_pipeworx tool that handles natural language queries instead of forcing you to call specific tools directly. Useful when you're prototyping integrations, need to look up API documentation programmatically, or want Claude to help you explore what's available in a particular API category without leaving your editor.
APIs.guru MCP — keyless directory of 2,500+ public APIs and their OpenAPI specs.
Part of Pipeworx — an MCP gateway connecting AI agents to 776+ live data sources.
| Tool | Description |
|---|
Add to your MCP client (Claude Desktop, Cursor, Windsurf, etc.):
{
"mcpServers": {
"apis-guru": {
"url": "https://gateway.pipeworx.io/apis-guru/mcp"
}
}
}
Or connect to the full Pipeworx gateway for access to all 776+ data sources:
{
"mcpServers": {
"pipeworx": {
"url": "https://gateway.pipeworx.io/mcp"
}
}
}
Instead of calling tools directly, you can ask questions in plain English:
ask_pipeworx({ question: "your question about Apis Guru data" })
The gateway picks the right tool and fills the arguments automatically.
