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.

Tools

Tool	What it does
modelradar_search	Filter the catalog by type / country / open-weights / min-context / query
modelradar_get	Full details for one model (id, name, or OpenRouter id)
modelradar_latest	Latest releases from the ModelRadar RSS feed
modelradar_recommend	Rank the best routable models for a need (live OpenRouter pricing + why)
modelradar_run	Route and execute: pick a model and run a completion via OpenRouter (needs OPENROUTER_API_KEY)

Install / run

npx modelradar-mcp           # or: git clone … && node server.mjs

The server speaks MCP over stdio.

// "cheapest open-weight coding model"
modelradar_recommend { "task": "coding", "open_weights": true, "prefer": "cheap" }
// → Granite 4.1 8B  ibm-granite/granite-4.1-8b  $0.05/MTok in  …

// route + run in one call
modelradar_run { "prompt": "Refactor this function…", "task": "coding", "prefer": "cheap" }
// → routed_to: ibm-granite/granite-4.1-8b · text: … · estimated_cost_usd: 0.0000x

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.
