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.
