unorouter-mcp

MCP server for UnoRouter, an open-source OpenAI-compatible gateway serving 200+ models (Claude, GPT, Gemini, DeepSeek, Kimi, GLM, Qwen and more) behind a single API key. Models with a :free suffix cost nothing.

Gives any MCP client (Claude Desktop, Claude Code, Cursor, Windsurf, and friends) three tools:

  • search_models: filter the live catalog, optionally free models only
  • get_pricing: USD per-1M-token list prices from the public pricing endpoint
  • chat: send a prompt to any model and get the reply with token usage

Setup

Create an API key at unorouter.com/token (Discord or GitHub sign-in, no card required).

Notes

  • Free models run on shared pools with a light per-model rate limit (about 1 request per minute per model); rotate between free models or use paid ones for throughput.
  • The whole UnoRouter stack is open source: github.com/unorouter.
