### Description (declared)

# Cartesia MCP Server

[![PyPI version](https://img.shields.io/pypi/v/cartesia-mcp)](https://pypi.org/project/cartesia-mcp/)

The Cartesia MCP server exposes [Cartesia](https://cartesia.ai/) APIs over the [Model Context Protocol (MCP)](https://modelcontextprotocol.io/) so clients such as **Cursor**, **Claude Desktop**, and **OpenAI Agents** can list voices, run **TTS** and **STT**, manage pronunciation dictionaries, clone voices, and more—without one-off scripts.

**Documentation:** [Cartesia docs — MCP](https://docs.cartesia.ai/tools/ai/mcp)

## Setup

**Hosted (recommended)** — connect to `https://mcp.cartesia.ai/mcp` and sign in when prompted. A Cartesia MCP API key is created for your organization if one does not exist yet. You can also connect from [API Keys](https://play.cartesia.ai/keys) in the Playground.

**Cursor** — [Install Cartesia MCP](cursor://anysphere.cursor-deeplink/mcp/install?name=cartesia-mcp&config=eyJ1cmwiOiJodHRwczovL21jcC5jYXJ0ZXNpYS5haS9tY3AifQ==), then sign in to the Playground when your browser opens.

**Claude Code:**

```bash
claude mcp add --transport http --scope user cartesia-mcp https://mcp.cartesia.ai/mcp
```

Run `/mcp`, select **cartesia-mcp**, and sign in when prompted.

Or add to `.cursor/mcp.json` / your client’s MCP config:

```json
{
  "mcpServers": {
    "cartesia-mcp": {
      "url": "https://mcp.cartesia.ai/mcp"
    }
  }
}
```

### Local (`uvx`)

Run the published package on your machine with an API key. Requires **[uv](https://docs.astral.sh/uv/)** (Python 3.13+ is installed by `uvx`) and a **[Cartesia API key](https://play.cartesia.ai/keys)**. Optionally set an **[admin API key](https://play.cartesia.ai/keys)** (Keys → Admin) for `get_credit_usage`. Admin keys and standard keys are separate credentials; each only works on its own route class.

**CLI** — `npx add-mcp "uvx cartesia-mcp" --name cartesia --env 'CARTESIA_API_KEY=${CARTESIA_API_KEY}'`

**Cursor** — [Install local Cartesia MCP](cursor://anysphere.cursor-deep…
