Equalang MCP server

Read from the package source without running it. The installed server may list more.

• cancel_jobwrite action

  Stop a queued or running job. A cancelled job is not charged; one that had already finished is left as it is.

• check_job

  Look a job up by id and, if it has finished, save its results. Use after a tool answered before its job was done.

• estimate_costwrite action

  Upload a local file without starting anything, and answer with the most a job on it can cost in credits. Free. Pass the returned file_id to translate_file or transcribe_recording so the file is not uploaded twice; kept_until says how long it is held. A recording is charged for the speech actually heard, usually less than the estimate.

• get_credit_balance

  How many credits the account has. Credits are bought at …/pricing; the same balance serves the website and this server.

• list_languages

  The language codes Equalang takes, with their names, read from the live API. Needs no key. Use it to turn a language's name into its code.

• transcribe_recordingwrite action

  Write down what is said in an audio or video file (mp3, m4a, wav, flac, ogg, aac, opus, mp4, mov, webm, mkv) as timed text, in the language spoken, and save it. For a translation of the recording use translate_file instead. Charged for the speech actually heard: silence and music are not.

• translate_file

  Translate a whole file into another language and save the result, keeping its layout, tables, images and formulas. Documents (pdf, docx, pptx, xlsx, epub, html, txt), subtitles (srt, vtt), pictures (jpg, png, webp, bmp), and recordings (mp3, m4a, wav, flac, ogg, aac, opus, mp4, mov, webm, mkv), which come back as translated subtitles. Answers with the paths written, never the contents.

• translate_text

  Translate plain text and answer with the translation. Pass texts for separate strings -- labels, messages: each translated on its own, answered in order, at most 50 texts of 5,000 characters, 20,000 characters per call. Pass text for one long text -- an article, a chapter, up to 100,000 characters: it is cut at sentences by Equalang, so do not split it yourself. For anything that is a file, use tr
