FreeTTS tools (7)

write = sends, deletes, buys or posts
  • check_usageFree

    Show the FreeTTS plan behind this connection and what is left: characters today or this month, requests a minute, HD voices, watermark. Use it when the user asks about limits, their plan, or why a request was refused.

  • dialogue_to_speechFree

    Turn a script with several speakers into one audio file, a different FreeTTS voice per speaker, with a pause between lines. Write each line as 'Name: text'. Use it for two-host shows, interviews, scenes, language lessons with two speakers. Needs a connected FreeTTS PRO account.

  • list_voicesFree

    List FreeTTS voices for a language or a search word, with the voice id to pass to text_to_speech. Says which voices are free and which need a FreeTTS PRO key (HD and Signature). Use it when the user names a language, accent or gender, or asks what voices exist.

  • script_to_tracksFree

    Record a script with exact timing, the way FreeTTS Script mode does: (pause 2) is exactly 2 seconds of silence, (beep), (ding) and (click) play a sound, 'CUE:' lines are read in a second voice, 'TRACK: name' starts a new audio file, 'NAME: line' makes a scene with a voice per character. Returns one file with everything plus one file per track. Use it for ear prompter tracks, voiceovers timed to footage, rehearsal tracks, workout or recipe step audio. Needs a connected FreeTTS PRO account.

  • suggest_voiceFree

    Suggest three FreeTTS voices for a language and a use (audiobook, tutorial, ad, news, children's story, meditation, podcast), with a short reason each. Use it when the user has not named a voice.

  • text_to_speechFree

    Convert text to spoken audio with a FreeTTS voice and return a download link to the MP3 (or WAV with a FreeTTS PRO key). Use it when the user wants text read aloud, narrated, or saved as an audio file. Without a FreeTTS key: standard voices, up to 2,000 characters a call, a short spoken "FreeTTS" tag at the end, file kept one hour. With a key: the account's plan (PRO: HD and Signature voices, no tag, 10,000 characters a call, files kept 30 days).

  • transcribe_audioFree

    Turn a recording into text with FreeTTS speech to text. Give a public https URL to an audio file (mp3, wav, m4a, ogg, webm). Needs a connected FreeTTS PRO account.

What the publisher says

From the FreeTTS repository's README, as published. We do not edit it. Read it on GitHub

FreeTTS MCP server

Text to speech inside Claude, ChatGPT, Cursor, VS Code, Codex, Windsurf, Gemini CLI and any other MCP client. One remote server, nothing to install:

https://mcp.freetts.org/mcp

Ask your assistant to read something aloud, and it calls FreeTTS and hands you an MP3 link.

What it does

Free without a key: standard voices, 2,000 characters a call and a day per connection, 10 requests a minute, a short spoken "FreeTTS" tag at the end, files kept one hour.

With a FreeTTS key (free account or PRO): the account's plan. PRO: HD and Signature voices, no tag, 10,000 characters a call, 1,000,000 a month, WAV, files kept 30 days, and the dialogue, Script mode and transcription tools. Keys: freetts.org/dashboard (API keys).

Add it to your client

Claude Code

claude mcp add --transport http freetts https://mcp.freetts.org/mcp

With a key: add --header "Authorization: Bearer ftlive...", or run /mcp inside a session to connect with the sign-in flow.

Claude (web, desktop, mobile): Settings, Connectors, Add custom connector, paste https://mcp.freetts.org/mcp. Free tools work at once; when a tool needs your account Claude shows Connect.

Cursor: Install in Cursor, or in ~/.cursor/mcp.json:

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

VS Code: Install in VS Code, or in .vscode/mcp.json:

{ "servers": { "freetts": { "type": "http", "url": "https://mcp.freetts.org/mcp" } } }

Codex CLI and ChatGPT desktop

codex mcp add freetts --url https://mcp.freetts.org/mcp

ChatGPT (web): Settings, Apps (Developer Mode), add https://mcp.freetts.org/mcp.

Windsurf, ~/.codeium/windsurf/mcp_config.json:

{ "mcpServers": { "freetts": { "serverUrl": "https://mcp.freetts.org/mcp" } } }

Any other client: use https://mcp.freetts.org/mcp as the server URL (Streamable HTTP). To use your account without the sign-in flow, send your key as Authorization: Bearer ftlive... or x-api-key: ftlive....

Full guide with copy buttons: freetts.org/developers/mcp.

Sign-in (OAuth)

The server is an OAuth 2.1 authorization server (PKCE, dynamic client registration, client ID metadata documents, RFC 9728 and 8414 metadata). Free tools need no sign-in. When a client calls a tool that needs your account, the server answers 401 and the client shows its Connect flow; the page asks for a FreeTTS API key from your dashboard and binds the connection to it. Delete the key in the dashboard to disconnect every assistant that used it.

Privacy

The text you send is sent to FreeTTS and its speech providers exactly as from the website, under the FreeTTS privacy policy. Calls without a key are metered by the caller's IP address. The server logs tool name, plan, character count, client name and outcome, never the text.
