# Text to speech MCP server: give your AI assistant a voice

Updated 2026-11-01

MCP (Model Context Protocol) lets an AI assistant use outside tools. The SuperClonica MCP server gives it a voice: the assistant finds a voice, voices your text and sends back a link to the audio file.

It works with the same API key and the same plan as the SuperClonica speech API, so a free key is enough to start.

## What the server does

The server lives at https://superclonica.com/mcp and offers three tools. list_voices searches the stock voices and every catalog voice (characters, narrators, announcers) by name in any language, tags and description. speak voices a text with one voice and returns a link to an MP3, OGG or WAV file that works for an hour. get_usage tells the plan and how many seconds of audio are left.

## Connect Claude Code

Create a free key on the speech API page, then run one command in a terminal: claude mcp add --transport http superclonica https://superclonica.com/mcp --header "Authorization: Bearer sc_YOUR_KEY". Replace sc_YOUR_KEY with your key. Claude Code lists the three tools in /mcp, and the assistant calls them when you ask for speech.

## Connect Cursor or VS Code

In Cursor, add the server to ~/.cursor/mcp.json: {"mcpServers": {"superclonica": {"url": "https://superclonica.com/mcp", "headers": {"Authorization": "Bearer sc_YOUR_KEY"}}}}. In VS Code, the file is.vscode/mcp.json: {"servers": {"superclonica": {"type": "http", "url": "https://superclonica.com/mcp", "headers": {"Authorization": "Bearer sc_YOUR_KEY"}}}}. Any other MCP client that supports remote HTTP servers with a custom header works the same way: the address plus the Authorization header.

## What to ask

Ask in plain words, for example: voice the sentence "Welcome to the dark side" in Darth Vader’s voice; find a calm female narrator and read this paragraph in English; how many seconds do I have left today. A voice can be named or given by its id; when several voices share a name, the assistant gets a short list to choose from. Clients that play audio can ask for the sound itself inside the answer.

## Limits and plans

The MCP server is part of the speech API plans. A free key voices 3 minutes of audio a day with any catalog voice; paid plans start at $5 a month for up to 216 hours of audio. One call takes up to 20,000 characters, and when a limit is reached the assistant gets a plain message with the time to retry instead of a failure.

## Frequently asked questions

### Is the text to speech MCP server free?

Yes, with a free key: 3 minutes of audio a day, no card. Paid plans raise the limit.

### Which AI assistants can use it?

Clients that connect to remote MCP servers over HTTP with a custom header, such as Claude Code, Cursor and VS Code. Clients that only accept OAuth sign-in cannot pass the key yet.

### Can the assistant play the audio?

It always gets a link to the file. Clients that play audio can also receive the sound inside the answer, up to 3 MB.

### Does it speak Chinese?

No. The voices speak 31 languages, and Chinese is not among them yet.

### Is there a local TTS MCP server?

The SuperClonica MCP server is hosted. For fully offline speech, install the free engine (python -m pip install superclonica-cpu): an assistant that can run terminal commands, such as Claude Code, can voice files with it on your computer.
