# MCP

The **`cartesia-mcp`** package exposes Cartesia through the **Model Context Protocol (MCP)** so MCP-capable clients—**Cursor**, **Claude Desktop**, **OpenAI Agents**, and similar—can list voices, run **TTS**, and use other Cartesia-backed tools via the protocol instead of custom scripts.

You need a [Cartesia API key](https://play.cartesia.ai/keys). The [PyPI package](https://pypi.org/project/cartesia-mcp/) currently requires **Python 3.13 or newer** as its minimum; confirm the supported version on PyPI before you install.

**Installation**, the **uvx** shortcut, and **MCP client configuration** (executable path, environment variables, Claude Desktop or Cursor) are documented in the **[cartesia-mcp](https://github.com/cartesia-ai/cartesia-mcp)** README so setup stays in sync with releases.
