Cursor FreeTTS batch_text_to_speech

How to: Cursor FreeTTS batch_text_to_speech

client:Cursor transport:streamable-http tool:batch_text_to_speech

Add FreeTTS to Cursor

  1. 01

    Open ~/.cursor/mcp.json and merge this in. Keep any servers already there.

{
  "mcpServers": {
    "mcp": {
      "url": "https://mcp.freetts.org/mcp"
    }
  }
}
  1. 02

    Save the file and restart Cursor.

  2. 03

    Ask for something batch_text_to_speech does. Cursor lists the server's tools on connect and calls batch_text_to_speech itself — you do not invoke it by name.

  3. 04

    If nothing happens, check the server is running and that FreeTTS's identifier in your config matches the one above exactly.

Use .cursor/mcp.json in a project root instead to scope it to that project. Cursor merges both. Cursor docs

Set these first

FreeTTS will not start until these are set, so batch_text_to_speech never becomes available.

Same tool, other clients

This list was read from the server itself, by connecting to it and calling tools/list on 14 November 2026. It is what the server actually exposes, not what its listing claims.

Mutating and Read-only are read off each tool's name, not its schema — a hint, not a guarantee. The registry stores tool names only; connect the server for its live schemas.
