Nothing serious here today

Today is the operative word: we check TTSForFree every 15 minutes and re-read its code on every release. Watch it and you find out the day that stops being true.

Available tools 21

Read directly from the server with tools/list, grouped by what they act on. If a tool disappears, we record the date.

favorite

add_favorite_voice

Save a voice to the user's favorites (only when the user asks).

list_favorite_voices

List the voices the user marked as favorites, in their saved order. Check this first when the user did not name a voice.

remove_favorite_voice

Remove a voice from the user's favorites (only when the user asks).

job

get_job_detail

Get a multi_voice_to_speech or srt_to_speech job with every segment: text, voice and its own audio_url, plus the merged audio. Use it to build captions or a Remotion/NLE timeline (one <Sequence> per segment; measure each file's duration in the renderer).

get_job_status

Check a speech job created earlier. Returns status (PENDING | SUCCESS | ERROR) and audio_url once SUCCESS. Never guess or fetch an audio URL before SUCCESS.

account

get_account_status

Show the user's plan tier, remaining characters/credits, max characters per request, max blocks per multi-voice/SRT job and API rate limits. Call before large jobs.

custom

list_my_custom_voices

List the user's personal voices created with Voice Design (from a text prompt) or Voice Clone (from an audio sample), plus the remaining custom-voice quota. Use `voice` from the result in any speech tool.

design

design_custom_voice

Create a new personal AI voice from a natural-language description (Gemini Voice Design). Uses one slot of the user's custom-voice quota - confirm with the user first. Good for a unique narrator or a character voice in a video/podcast. Returns the new `voice` token.

estimate

estimate_video_localization

Estimate the credits to dub one video into one or more languages (speech-to-text + translation + voice + video merge) before running localize_video. Pass video_url (duration is measured) or duration_seconds.

languages

list_languages

List every language supported by TTSForFree text-to-speech. Returns language codes to pass to list_voices.

localization

get_localization_status

Status of localize_video jobs: current step, and when Completed the dubbed audio_url, final_video_url and translated SRT for each language.

localize

localize_video

Full automatic dubbing of an uploaded video: transcribe once, translate, voice every target language with its own voice and render a dubbed video per language. Each language returns an audio_url (voice track aligned to the original timeline - upload it to YouTube Studio as a multi-language audio track) and a final_video_url. Takes several minutes: returns job_guids immediately; poll get_localization_status. Confirm the cost with estimate_video_localization for long videos.

multi

multi_voice_to_speech

Render ordered segments, each with its own voice, into ONE merged MP3. Use for podcasts, dialogues, interviews, audio dramas or explainer videos with several speakers when there are no fixed timestamps. Consumes credits.

recent

list_recent_jobs

List the user's most recent speech jobs with status and audio URLs, to reuse earlier audio instead of paying again.

srt

srt_to_speech

Create ONE MP3 that follows a subtitle timeline: every cue starts at its timestamp and speech speed auto-fits the cue duration. Use for video voiceover, dubbing translated subtitles, YouTube localization, tutorials and any edit where audio must line up with existing video. Pass either raw `srt` (SRT or WebVTT text) or `segments` with start_ms/end_ms. For several speakers set `speaker_voices` and prefix cue text with '[Name]' or 'Name:'. The resulting MP3 starts at 00:00 of the video, so it can be muxed directly with ffmpeg (commands are returned). Consumes credits.

text

text_to_speech

Convert one text into one MP3 with one voice. Use for narration, voiceover scripts, articles, lessons, announcements or any audio whose length can follow the speech. Consumes credits (characters x voice rate). Returns job_id, status and audio_url when ready.

transcribe

transcribe_media

Speech-to-text for an uploaded video or audio file: returns timestamped SRT (the timeline to rewrite, translate or re-voice with srt_to_speech). Credits are charged per second of media, measured by the server. Use language = the spoken language code from list_languages.

transcription

get_transcription

Check a transcribe_media job and get its SRT once finished.

upload

create_upload_url

Get a one-time URL to upload a local video or audio file (mp4, mov, webm, mkv, mp3, wav, m4a...) up to 2 GB. Upload with HTTP PUT of the raw bytes, e.g. `curl -T video.mp4 "<upload_url>"` (valid 15 minutes), then pass `public_url` to transcribe_media or localize_video. Only files uploaded here (or on ttsforfree.com) are accepted; YouTube and other external links are never downloaded. If you cannot run commands, ask the user to upload the file on https://ttsforfree.com/en/video-localization/ and paste the file link.

voice

get_voice_details

Get full metadata for one voice token: persona, use case, accent, pitch, styles, preview audio and credit cost.

voices

list_voices

Search the AI voice catalog for one language. Each result has a `voice` token (v1:...) - pass it unchanged as `voice` to text_to_speech, multi_voice_to_speech or srt_to_speech. Results are sorted by popularity; `can_use=false` means the user's plan cannot use that voice. Prefer the user's favorite or custom voices when they exist.

TTSForFree — questions

Answers built from our own checks of this server.

What can TTSForFree do?

It exposes 21 tools, read directly from the server on our last check. Among them: add_favorite_voice, create_upload_url, design_custom_voice, estimate_video_localization, get_account_status, get_job_detail and 15 more. The full list with descriptions is on this page — we take it from the server itself via tools/list, not from a README. How MCP servers expose tools in the first place →

What is TTSForFree mostly used for?

Its tools cluster around favorite and job. That is what this server is built to work with — the grouping comes from the actual tool names, not from a category we assigned.

Is TTSForFree working right now?

We send a real MCP handshake every 15 minutes. Over the last 24 hours 92 of 92 checks got a reply (100.0%), average response time 880 ms. The bar chart above shows every period we have measured.

How do I connect TTSForFree?

Copy the ready config from this page. We generate it for Claude Code, Claude Desktop, Codex, Cursor and VS Code, each in the form that client actually reads. It is a remote server, so there is nothing to install — the client connects to the address.

Does TTSForFree need an API key?

No. TTSForFree completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 21 of them are readable on this page. This is what we observed, not what the docs claim.

How fast is TTSForFree?

It answers our handshake in 880 ms on average, which is faster than 9% of all working MCP servers we measure. That is on the slow side — worth knowing if the tool sits inside an interactive loop. The comparison comes from our own checks across the whole registry, every 15 minutes.

Is TTSForFree open source?

We cannot say either way: 0 stars on GitHub and 1 open issue, but we could not determine the licence, and without one the code is not open source by default.
