# model-version-mcp

MCP server that provides up-to-date AI model names and pricing from [models.dev](https://models.dev).

Solves the problem of AI models hallucinating outdated model names by providing a live-fetched, filtered list of recently released models.

## Tool

### `get_ai_models`

Returns AI models released within the last 4 months with pricing data.

**Parameters:**
- `provider` (optional): Filter by provider name, e.g. `"anthropic"`, `"openai"`, `"google"`

**Returns:** JSON with model id, name, provider, release_date, cost ($/1M tokens), context window, and capabilities.
