APIs.guru MCP — keyless directory of 2,500+ public APIs and their OpenAPI specs. https://apis.guru

Installation

Ajoutez ceci à la configuration MCP de votre client (Claude Desktop : claude_desktop_config.json ; Cursor : .cursor/mcp.json ; VS Code et les autres utilisent la même forme « mcpServers »).

Remote (streamable-http)
Claude Code
claude mcp add --transport http apis-guru 'https://gateway.pipeworx.io/apis-guru/mcp'
Configuration JSON (Claude Desktop, Cursor, VS Code)

APIs.guru MCP — keyless directory of 2,500+ public APIs and their OpenAPI specs. https://apis.guru

Part of Pipeworx — an MCP gateway connecting AI agents to 1872+ live data sources. This is an independent, unofficial integration — not affiliated with, endorsed by, or published by the upstream provider.

Tools

ToolDescription
search_apisSearch the APIs.guru directory of 2,500+ public APIs by free-text query. Matches against the API's name/key, its title, description, and categories. Returns a list of matching APIs each with name (the directory key, e.g. "stripe.com" or "googleapis.com:calendar"), title, truncated description, provider, categories, preferred version, last-updated date, docs link, and OpenAPI/Swagger spec URL. Use this to discover which public APIs exist for a given domain (payments, weather, maps, etc.) and to get the exact name to pass to get_api.
get_apiGet the full directory entry for one API by its exact APIs.guru name/key (e.g. "stripe.com" or "googleapis.com:calendar"). Returns every version of that API with its info (title, description, provider, categories), last-updated date, docs link, and OpenAPI/Swagger spec URLs (swaggerUrl JSON + swaggerYamlUrl YAML), plus which version is preferred. Use this once you know the exact name (from search_apis) to fetch the spec URLs for an API.
list_providersList all API providers (domains like "googleapis.com", "azure.com", "amazonaws.com") tracked in the APIs.guru directory. Returns { count, providers }. Use this to browse the directory by organization before drilling into a specific provider or API.
get_metricsGet aggregate statistics for the entire APIs.guru directory, e.g. total number of APIs, providers, endpoints, and specs (numAPIs, numEndpoints, numSpecs, ...). Use this for a high-level summary of how much public-API coverage the directory has.

Quick Start

Add to your MCP client (Claude Desktop, Cursor, Windsurf, etc.):

{
  "mcpServers": {
    "apis-guru": {
      "url": "https://gateway.pipeworx.io/apis-guru/mcp"
    }
  }
}
What this endpoint actually serves

tools/list at https://gateway.pipeworx.io/apis-guru/mcp returns the tools in the table above plus the shared Pipeworx meta-tools — ask_pipeworx, discover_tools, search_within, remember/recall and the rest of the gateway-wide set. So the tool count you see is larger than this table: a single-pack endpoint currently lists roughly 30 shared tools alongside the pack's own. The connection's initialize response states its exact scope, and is the authoritative answer for a given day.

This is deliberate, not multiplexing by accident. The meta-tools are what let a scoped connection answer a question this pack does not cover — via ask_pipeworx, which routes across the whole catalog — without you adding a second MCP server. There is currently no way to mount a pack endpoint without them; if the extra schemas cost you more context than the routing is worth, connect to the full gateway once rather than to several pack endpoints.

Or connect to the full Pipeworx gateway to get every pack's tools listed directly, instead of just this one's:

{
  "mcpServers": {
    "pipeworx": {
      "url": "https://gateway.pipeworx.io/mcp"
    }
  }
}

Both URLs reach the same gateway and the same 1872+ data sources. The only difference is which pack's tools are listed directly; ask_pipeworx reaches all of them from either one.

No MCP client? Call it over HTTP

curl -X POST https://gateway.pipeworx.io/v1/tools/search_apis \
  -H 'Content-Type: application/json' \
  -d '{"query":"payments"}'

No account needed for the first calls. Inspect any tool: GET https://gateway.pipeworx.io/v1/tools/search_apis. Find one: POST https://gateway.pipeworx.io/v1/tools/search_packs with {"query":"..."}.

Standalone (no gateway account)

This package also runs as a local stdio MCP server — no Pipeworx account, no gateway round-trip:

{
  "mcpServers": {
    "apis-guru": {
      "command": "npx",
      "args": ["-y", "@pipeworx/mcp-apis-guru"]
    }
  }
}

Or run it directly to confirm it starts:

npx -y @pipeworx/mcp-apis-guru

It speaks MCP over stdin/stdout and answers initialize/tools/list/tools/call for only this pack's tools — none of the shared meta-tools the gateway connection above adds. Same source, same tools, no ask_pipeworx routing.

Using with ask_pipeworx

Instead of calling tools directly, you can ask questions in plain English — this works on the pack endpoint above as well as on the full gateway:

ask_pipeworx({ question: "your question about Apis Guru data" })

The gateway picks the right tool and fills the arguments automatically.
