ModelRadar MCP

An MCP server that turns the curated ModelRadar catalog into a model router between OpenRouter and your CLI / agent.

• 🔎 Discover — search the catalog, read the latest releases straight from the RSS feed

• 🧭 Route — given a need (coding, cheap, open-weights, long-context, multimodal…), get the best OpenRouter-routable model with live pricing and a rationale

• ⚡ Execute — optionally run the completion through OpenRouter on the chosen model (recommend → route → answer + cost)

Dependency-free. One file, Node ≥ 18, no build step.

// → Granite 4.1 8B  ibm-granite/granite-4.1-8b  $0.05/MTok in  …

// route + run in one call

How it works

ModelRadar curates the model catalog (/api/models) and publishes new releases via RSS (/feed.xml). This server reads both, enriches routable models with live OpenRouter pricing, scores them against your request, and (optionally) executes the chosen model through the OpenRouter chat API. ModelRadar is the map; OpenRouter is the road; this MCP is the router in between.
