The OpenWeb Ninja MCP Server

One connection gives any MCP-compatible AI agent (Claude, Cursor, Cline, Windsurf, and more) live access to 50+ OpenWeb Ninja APIs as tools. Add the server once with your API key, then just ask in plain language.

Set it up in seconds

The server runs via npx. There's nothing to install globally. Add it to your client's MCP config with your OpenWeb Ninja API key, and every API becomes a tool your agent can call.

How it works

Each tool maps to one OpenWeb Ninja API and exposes that API's operations. Your agent reads the tool descriptions, chooses the operation and parameters, and calls it with no per-request wiring. Schemas are generated directly from our live OpenAPI specs, so the tools always match the APIs.

If your agent reaches for an API your key isn't subscribed to, it can subscribe to that API's free tier on the spot and continue, so it can expand its own capabilities mid-task without you touching the portal.
