# Cartesia MCP Server The Cartesia MCP server provides a way for clients such as Cursor, Claude Desktop, and OpenAI agents to interact with Cartesia's API. Users can localize speech, convert text to audio, infill voice clips etc. ## Cartesia Setup Ensure that you have created an account on [Cartesia](https://play.cartesia.ai/sign-in), there is a free tier with 20,000 credits per month. Once in the Cartesia playground, create an API key under API Keys --> New. ## Installation ```sh pip install cartesia-mcp which cartesia-mcp # absolute path to executable ``` ## Claude Desktop Integration Add the following to `claude_desktop_config.json` which can be found through Settings --> Developer --> Edit Config. ``` { "mcpServers": { "cartesia-mcp": { "command": "<absolute-path-to-executable>", "env": { "CARTESIA_API_KEY": "<insert-your-api-key-here>", "OUTPUT_DIRECTORY": // directory to store generated files (optional) } } } } ``` Try asking Claude to - List all available Cartesia voices - To convert a text phrase into audio using a particular voice - To localize an existing voice into a different language - To infill audio between two existing audio segments (specify absolute paths to audio files) - To change an audio file to use a different voice ## Cursor Integration Create either a `.cursor/mcp.json` in your project or a global `~/.cursor/mcp.json`. The same config as for Claude can be used.
