```json
{
  "mcpServers": {
    "index9": {
      "command": "npx",
      "args": ["-y", "@index9/mcp"]
    }

## 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](https://openrouter.ai/keys):

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

Your key is passed per-request and never stored.
