Measured tools (6)

• count_text read-only

  Use this when the user asks how long a text is, for example "how many words is this", "character count for this tweet", "will this fit in one SMS", "how long does this take to read". Input tips: pass text exactly as written, up to 20,000 characters (about 3,500 words); do not trim or fix it. Returns: characters, characters without spaces, graphemes (user-perceived characters), words, sentences, paragraphs, lines, UTF-8 bytes, SMS encoding, units and segments, reading minutes, and Flesch reading ease and grade (English only, null otherwise), with the rule used for each count. Not for: counting text inside a file, PDF or spreadsheet the tool cannot see (paste the text instead), or counting tokens for a model. Errors: a text over the limit is refused; split it and add the counts. The text is not stored.

  Parameters:

  • text (required) — string — The text to count, exactly as the user wrote it (at most 20000 characters, about 3,500 words).

• make_calendar_file

  Use this when the user wants a calendar file to import, for example "make a calendar file for this meeting", "create an .ics for my weekly class", "export these dates so I can import them". Input tips: pass 1 to 50 events, each with a title, a start (2026-11-02 for all day, or 2026-11-02T09:30) and an end or duration_minutes, plus timezone (IANA name such as Europe/Paris) for a time without Z or an offset; ask the user for the time zone, never guess it. Example event: {"title":"Sprint review","start":"2026-11-02T09:30","duration_minutes":45,"timezone":"Europe/Paris"}. Optional: location, description, reminder_minutes and recurrence (freq daily, weekly, monthly or yearly, with interval, until or count, and byday). Returns: the .ics text, a download link that works for 24 hours, its expiry and the event count. Not for: adding, changing or reading events in Google Calendar, Outlook or any calendar account; it only makes a file. Errors: status invalid with a message naming the event and field to fix.

  Parameters:

  • events (required) — array — 1 to 50 events, such as [{"title":"Sprint review","start":"2026-11-02T09:30","duration_minutes":45,"timezone":"Europe/Paris"}].
  • filename — string — File name in letters and digits, such as sprint-review; .ics is added.

• make_csv_file

  Use this when the user wants a new CSV file from a table, for example "put this table in a CSV", "make a spreadsheet file from these rows", "export this list as CSV for Excel". Input tips: pass columns (header names) and rows, where each row has exactly one cell per column (text, number, true, false or null for empty). Example: columns ["name","city"], rows [["Ada","London"],["Linus","Helsinki"]]. Up to 2,000 rows and 100 columns. Optional: filename, excel_bom (true when the user opens it in Excel and the text has accents) and escape_formulas (show cells starting with = + - or @ as text). Returns: the CSV text, a download link that works for 24 hours, its expiry, the row count and byte size. Not for: opening, reading, editing or adding up an existing spreadsheet or .xlsx file; it only writes a new CSV. Errors: status invalid with a message naming the row and cell to fix.

  Parameters:

  • columns (required) — array — Header names in order, such as ["name","city","note"].
  • rows (required) — array — Up to 2000 rows, such as [["Ada","London","first program"]]. Each row has exactly one cell per column. An empty list gives a header-only file.
  • filename — string — File name in letters and digits, such as contacts; .csv is added.
  • excel_bom — boolean — Start the file with a UTF-8 byte order mark so Excel opens accents correctly. Default false.
  • escape_formulas — boolean — Prefix text cells that start with = + - or @ with an apostrophe so a spreadsheet shows them as text. Default false.

• translate_page read-only

  Use this when the user wants to translate a public webpage, documentation or public-domain text that they own or have the rights to translate. Input tips: url of the page (http or https), target_lang as a language code such as vi, es, fr, de, ja, zh, pt, ko, and confirm_rights true only after the user confirms the rights. Returns: clean Markdown with headings, lists and code kept, usually in 5 to 15 seconds for a page of up to 8,000 characters, plus characters left today. Not for: copyrighted fiction, manga, manhwa or commercial comics, pasted text, local files or pages behind a login. Errors and next step: rights_not_confirmed (ask the user, then set confirm_rights true); page_too_large over 12,000 characters (offer a shorter page, such as one chapter on its own URL); fetch_failed or no_content (check the URL opens without a login, or pick a page whose text is in the HTML); daily_translation_spent (the daily character limit is used up; try again after 00:00 UTC); translation_failed (try again in a minute).

  Parameters:

  • url (required) — string — Public webpage URL to fetch and translate, such as https://example.com/docs/start (http or https; local and private addresses are blocked).
  • target_lang (required) — string — ISO 639-1 code of the language to translate into, such as vi (Vietnamese), es, fr, de, ja, zh, pt, ko, ru, ar or hi. A few are 3 letters: ast, ceb, ilo.
  • confirm_rights (required) — boolean — Set true only after the user has confirmed they own this page or have the rights to translate it (docs, public domain, or user-owned content). Must not be used for copyrighted fiction or comics.
  • source_lang — string — Optional ISO 639-1 code of the page language, such as en. Read from the page HTML (or en) when omitted.

• submit_feedback

  Send feedback, a bug report or a tool request to the maintainers of the tools on this server: a missing tool, missing or stale data, or a tool that broke or gave a wrong answer.

  • message (required) — string — What you need or what broke, in plain words, at most 1000 characters. Links, email addresses and phone numbers are removed. Never include secrets or personal details.
  • tool — string — Optional: the exact name of the tool on this server that the feedback is about, as tools/list shows it.
