Text to speech in 149 languages: MP3 links from any assistant. Free without an account.
FreeTTS turns text into spoken audio: an assistant can pick a voice, generate an MP3 download link, and, with a PRO account, build dialogues and transcribe.
Web executable via Streamable HTTP. Remote servers run from the web runtime once configured in a workspace.
Paste this prompt into Claude Code, Codex, Cursor or another agent — or into SourceWeft chat. The agent reads this server's install guide, shows you its publisher, endpoint and sign-in, and adds it to your client once you agree. Keys never go into a command.
Read https://sourceweft.com/mcp/org.freetts%2Fmcp/install.md and connect the MCP server it describes to my client. Before changing any config, show me its publisher, endpoint and sign-in method and wait for my OK. Never put an API key in a command or in a file I would commit; ask me where it should come from.Add this to your client's mcpServers config.

}Text to speech inside Claude, ChatGPT, Cursor, VS Code, Codex, Windsurf, Gemini CLI and any other MCP client. One remote server, nothing to install:
Ask your assistant to read something aloud, and it calls FreeTTS and hands you an MP3 link.
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).
Claude Code
With a key: add --header "Authorization: Bearer ft_live_...", 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:
VS Code: Install in VS Code, or in .vscode/mcp.json:
Codex CLI and ChatGPT desktop
ChatGPT (web): Settings, Apps (Developer Mode), add https://mcp.freetts.org/mcp.
Windsurf, ~/.codeium/windsurf/mcp_config.json:
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 ft_live_... or x-api-key: ft_live_....

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.
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.
The same server also runs on your own machine, for clients that start local servers or when you would rather keep a key in a local config. It talks to the public FreeTTS API with your own key. Get one at freetts.org/dashboard (API keys; a free account has one).
Claude Desktop, Cursor, Cline, Windsurf and similar clients:
Without a key it still starts: list_voices, suggest_voice, the prompts and the resources work, and making audio asks for a key. The hosted server at https://mcp.freetts.org/mcp needs no key at all.
From source: npm install && npm run build && node dist/stdio.js. Node.js 20 or later.
The hosted server itself (dist/index.js) runs next to the FreeTTS API on FreeTTS's own machines and is not meant to be self-hosted; the code is here so you can read exactly what it does.

List FreeTTS voices
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.
limitgendersearchlanguagefree_onlySuggest a FreeTTS voice
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.
usegenderlanguagerequiredText to speech (FreeTTS)
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).
textrequiredspeedvoiceformatlanguageinclude_audioCheck FreeTTS usage and plan
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.
Takes no parameters.
Dialogue to speech (two or more voices)
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.
scriptrequiredvoiceslanguagepause_msScript to timed tracks (Script mode)
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.

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.

How complete this listing is, computed from the registry entry, the endpoint and public sources. Not a rating of the server and not a statement that it is safe or working today: reachability is a dated check, and no installs or reviews go into the score.
