UnoRouter MCP: search, price and query 200+ AI models

UnoRouter puts 200+ AI models behind one OpenAI-compatible key, most of them free. Its MCP server lets your AI app search that catalog, look up per-token pricing and send a prompt to any model for a second opinion. It's public, and ContextGate connects its three tools to Claude, ChatGPT and Cursor with a policy check on every prompt.

Plug UnoRouter's model catalog into your AI app

  1. 1Click Connect UnoRouter free. There's no sign-in, so its tools are ready at once.
  2. 2All three tools are on. `search_models` and `get_pricing` only read the catalog, while `chat` sends your prompt to another model; switch off `chat` if prompts shouldn't go to third-party models.
  3. 3Add ContextGate to your AI app as a connector or MCP server. The steps for each app are on the Works with page.
  4. 4Ask your AI app which free models UnoRouter lists and what a paid one costs per million tokens, then open Activity to see the calls.

Model shopping from your AI app

  • Search the live catalog of 200+ models with `search_models`; model IDs ending in :free cost nothing.
  • Look up USD list prices per million tokens with `get_pricing`.
  • Send one prompt to another model with `chat` and compare its answer with your AI app's own.

Prompts that leave, checked

  • Workspace policies check every `chat` call, so a secret pasted into a prompt can be blocked before another model sees it.
  • Switch off `chat` and your AI app can browse models and prices but not send prompts.
  • Activity records each prompt sent through UnoRouter.
