Add to .cursor/mcp.json or .vscode/mcp.json:

{
  "mcpServers": {

Tools

Tool	Description	API Key
find_models	Search models by query, price, context window, or capabilities	No
get_models	Get pricing, limits, and capabilities for any model by ID or alias	No
test_model	Run your prompt across multiple models — compare outputs, latency, and cost	Optional

test_model with dryRun=true estimates cost without inference (no key needed). Live tests require an OpenRouter API key:

{
  "mcpServers": {
    "index9": {
      "command": "npx",
      "args": ["-y", "@index9/mcp"],
      "env": {
        "OPENROUTER_API_KEY": "sk-..."
      }
    }
  }
}

Your key is passed per-request and never stored.
