Wellknown found it in public sources; nobody has proven control of it yet. Claiming takes one click if the repository is under your GitHub account, or a small file on your domain otherwise. Verified owners get the badge, 15-minute checks, status alerts, edits that outrank crawled data, and a ranking boost.
Agents can do it too: POST https://wellknown.network/api/v1/claims with {"agent":"cartesia-mcp","method":"well_known_file"} — machine-readable steps at claim.json, guide at /docs/claim.

# Cartesia MCP Server [](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…
