Pick your app above. We remember it, so next time the button says “Install in …”.

Open Claude Desktop → Settings → Developer → Edit Config, and paste this into claude_desktop_config.json

{
  "mcpServers": {
    "superclonica": {
      "command": "uvx",
      "args": [
        "superclonica-mcp"
      ],
      "env": {
        "SUPERCLONICA_API_KEY": "your-value",
        "SUPERCLONICA_DEVICE": "your-value"
      }
    }
  }
}

Run this in your terminal

claude mcp add superclonica --env SUPERCLONICA_API_KEY=your-value --env SUPERCLONICA_DEVICE=your-value -- uvx superclonica-mcp

Fill in the empty values before running it.

Open in Cursor

Or copy the settings yourself

Paste into .cursor/mcp.json in your project, or ~/.cursor/mcp.json

{
  "mcpServers": {
    "superclonica": {
      "command": "uvx",
      "args": [
        "superclonica-mcp"
      ],
      "env": {
        "SUPERCLONICA_API_KEY": "your-value",
        "SUPERCLONICA_DEVICE": "your-value"
      }
    }
  }
}

Your browser asks to open the app, then the app shows the settings and asks you to confirm. Key values are left empty for you to fill in.

Open in VS Code

Or copy the settings yourself

Paste into .vscode/mcp.json in your project

{
  "servers": {
    "superclonica": {
      "type": "stdio",
      "command": "uvx",
      "args": [
        "superclonica-mcp"
      ],
      "env": {
        "SUPERCLONICA_API_KEY": "your-value",
        "SUPERCLONICA_DEVICE": "your-value"
      }
    }
  }
}

Your browser asks to open the app, then the app shows the settings and asks you to confirm. Key values are left empty for you to fill in.

This one runs on your computer, and ChatGPT can only connect to servers on the internet. Pick another app.

Common questions

Is SuperClonica text to speech safe?

It passed 1 of 1 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.

What keys or codes does it need?

You need to fill in: SUPERCLONICA_API_KEY

Does it run on my computer or in the cloud?

It runs on your computer. Your AI app starts it when needed, and data does not pass through the maker’s servers (unless it calls an online service itself).

Is it still maintained?

The GitHub repo last changed –, and the latest version (0.1.1) reached the registry 6 days ago.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. You also need Python (uv) on your computer.

What can I use instead?

SuperClonica MCP server

Text to speech for Claude and other MCP clients, running on your own computer: offline after the first run, no limits, 31 languages. It is the local sibling of the cloud server at https://superclonica.com/mcp, with the same tool names. Voices come from the SuperClonica catalog.

Works on Windows, macOS and Linux with Python 3.10 or newer. Chinese is not supported.

Set it up

You need uv, which gives the uvx command. The first start installs the engine, which takes a minute or two. The first speak downloads the voice model (about 400 MB) once.

Claude Desktop. Add this to claude_desktop_config.json and restart the app:

"mcpServers": { "superclonica": { "command": "uvx", "args": ["superclonica-mcp"], "env": { "SUPERCLONICA_API_KEY": "sc_..." } } } }

If the app cannot find uvx, put the full path to it in command. On Windows where uvx prints it, on macOS and Linux which uvx.

Claude Code:

claude mcp add superclonica -e SUPERCLONICA_API_KEY=sc_... -- uvx superclonica-mcp

Cursor (~/.cursor/mcp.json) takes the same JSON as Claude Desktop. VS Code (.vscode/mcp.json) takes the same entry under "servers", with "type": "stdio" added.

Without uvx, these start the same server: pipx run superclonica-mcp, or python -m superclonica_mcp after pip install superclonica-mcp.

The API key is optional. Stock and free catalog voices need none. Installing a bought or your own voice does; creating a key is free.

Tools

Tool	What it does
`list_voices(query?, limit?)`	Voices on this computer and, when online, the catalog. Shows for each whether it is installed, yours, free or must be bought, with its page.
`speak(text, voice, language, format?, output_path?, include_audio?)`	Voices the text on this computer and saves mp3, wav or ogg. Gives the file's path and length, and the audio itself if asked. Up to 20000 characters per call. An existing file is never overwritten.
`install_voice(voice)`	Downloads a voice you may use to this computer. A version you already have is not downloaded again.
`buy_voice(voice)`	Gives the link to the voice's page. It never pays: you buy in your browser, then tell the assistant to install it.
`play(path)`	Plays an mp3, wav or ogg file with the system player.
`get_usage()`	Whether the model is loaded and on what device, and which folders are used. The local engine has no limits.

voice is an id from list_voices, a stock name (F1–F5, M1–M5) or an exact name. When a name fits several voices you get the candidates to choose from, never a guess.

To use your own voice file, put its JSON in the voices folder. It goes by its file name.

Buying a voice

Ask for a voice, for example "find a calm narrator". The assistant calls list_voices.
If it must be bought, the assistant calls buy_voice and gives you a link that opens the purchase window.
Confirm the purchase in your browser. Only your click can buy.
Say "install it". After that the voice works offline.

Settings

All are optional environment variables.

Variable	Meaning	Default
`SUPERCLONICA_API_KEY`	Key for installing bought and your own voices	none
`SUPERCLONICA_VOICES_DIR`	Folder of voices	Windows `%APPDATA%\SuperClonica\voices`; macOS `~/Library/Application Support/SuperClonica/voices`; Linux `~/.local/share/superclonica/voices`
`SUPERCLONICA_OUTPUT_DIR`	Folder for audio	`audio` beside the voices folder
`SUPERCLONICA_DEVICE`	`cpu` or `gpu`	GPU if the GPU engine is installed, else CPU

Faster on an NVIDIA GPU

uvx superclonica-mcp installs the CPU engine, and the CPU and GPU engines cannot share one environment. For the GPU engine (Windows or Linux x86-64, Python 3.11+), make an environment of its own:

uv venv superclonica-gpu --python 3.12

uv pip install --python superclonica-gpu superclonica-gpu-cuda uv pip install --python superclonica-gpu --no-deps superclonica-mcp uv pip install --python superclonica-gpu "mcp>=2.3,<3" "truststore>=0.10"

Then use the Python of that environment as the command, with -m superclonica_mcp as the arguments and SUPERCLONICA_DEVICE=gpu in env.

When something goes wrong

"The voice model is still loading": the first run is downloading the model, and that goes on in the background. Ask again in a minute.
The client shows no tools: look at the server's log (Claude Desktop: *Settings → Developer*). The server writes its log only to stderr.
A long text times out: on a CPU, voice long texts in parts.
