## MCP tools (6)

### `generate_password` (~186 tokens)

Password generator

Generates a strong random password with a cryptographically secure generator.

WHEN TO USE: the user asks for a password or a random key.

HOW IT WORKS: always uses upper and lower case letters; numbers and symbols are optional. Each selected kind of character appears at least once. length: 8 to 64 (default 16).

RETURNS: password, the options used, and link — this tool's web page with the same options. The password is never in the link. Show the password to the user as it is; do not store it or repeat it elsewhere.

Input parameters:

- `length` (integer): Number of characters, 8 to 64. Default 16.
- `numbers` (boolean): Include digits 0-9. Default true.
- `symbols` (boolean): Include symbols such as !@#$%. Default true. Set false for systems that reject symbols.

### `compare_timezones` (~392 tokens)

Time zone comparison

Converts one moment across several time zones, daylight saving time included.

WHEN TO USE: "what time is it in…", scheduling a meeting across cities, checking whether a time falls at night or on another day somewhere.

HOW IT WORKS:
\- zones: IANA time zone names in Area/City form — America/Sao_Paulo, Europe/Lisbon, Asia/Tokyo, UTC. Not city names alone, abbreviations (EST, BRT) or offsets (GMT-3). The FIRST zone is the reference for date and hour. 1 to 12 zones.
\- date (YYYY-MM-DD) and hour (0–23) are read in the first zone. Without them: the current moment. Only hour: that hour today in the first zone. Only date: that day at the current hour.
\- format: 24h (14:00) or 12h (2:00 PM).

RETURNS: the moment in UTC and, for each zone, its local date, weekday, time, UTC offset and dayShift (+1 = next day, -1 = previous day, relative to the first zone). link: this tool's web page with the same comparison.

ERRORS name the unknown zone or the invalid date; fix it and call again.

Input parameters:

- `date` (string): The day, as YYYY-MM-DD, in the first time zone. Defaults to today there.
- `format` (string): How times are written: 24h (14:00) or 12h (2:00 PM).
- `hour` (integer): The hour, 0 to 23, in the first time zone. Defaults to the current hour there.
- `zones` (array): IANA time zone names, such as America/Sao_Paulo or Europe/London. The first one is the reference. 1 to 12.

### `data_to_chart` (~410 tokens)

CSV to chart

Draws a chart from a CSV table and returns it as an image.

WHEN TO USE: the user wants to see data as a chart, or needs a chart image for a document, a README, a slide or a chat.

HOW IT WORKS:
\- csv: a header row, then data rows. First column: the category (or x value); the next columns: numbers. Use a comma or semicolon as separator; decimals with a point, or with a comma when the separator is a semicolon. Up to 20,000 characters.
\- chartType, and what each one needs:
  bar, horizontalBar, line, area, pie, donut, funnel — one category column + one numeric column;
  multiline — one x column + one or more numeric columns (one line per column);
  scatter — two numeric columns (x, y);
  heatmap — three columns: row, column, value.
\- title: optional, drawn at the top.

RETURNS:
\- image: a PNG address that IS the chart (rendered on request) — put it straight into Markdown (![title](image)) or an <img>. imageSvg: the same as SVG, sharper where SVG is accepted. Both are null when the CSV is too long to fit in an address; then use svg.
\- svg: the chart as SVG markup.
\- link: this tool's web page with the same chart, to edit it.

ERRORS say what is wrong with the CSV (missing columns, non-numeric values, too many rows); fix the data and call again.

Input parameters:

- `chartType` (string): The kind of chart. See the tool description for the columns each kind needs.
- `csv` (string, required): The data as CSV with a header row. First column: category or x value; next columns: numbers. Up to 20,000 characters.
- `title` (string): Optional title drawn at the top of the chart. Empty for none.

### `text_to_speech` (~641 tokens)

Text to speech

Reads a text aloud with a Microsoft neural voice (the voices of Edge's "Read aloud") and returns an MP3.

WHEN TO USE: the user wants to hear a text or needs an audio file of it — narration, audiobook, lesson, voice-over, a message read aloud.

HOW IT WORKS:
\- Up to 50,000 characters per call. A text over 1,000 characters is split by sentence into parts of up to 1,000; each part is voiced in order and the parts are joined into ONE MP3. Progress is reported per part ("Gerando áudio... 3 de 18"), so keep waiting while it arrives.
\- It takes time: about 5 seconds per part. 5,000 characters ≈ 30 s; 16,000 ≈ 2 min; 50,000 ≈ 6 min.
\- Over 50,000 characters: split the text at paragraph boundaries into several calls with the same voice and speed, and give the user every link, in order.
\- Send the text as it should be HEARD: remove Markdown marks (**, #, list bullets), URLs, emojis and tables. Do not summarize, translate or reword unless the user asked — every word you send is read.
\- voice: choose one in the language of the text (the prefix is language-region: pt-BR, pt-PT, en-US, es-MX…). Brazilian Portuguese: pt-BR-FranciscaNeural (female, default) or pt-BR-AntonioNeural (male).
\- speed: 1 is the voice's natural pace; 0.9 suits calm narration, 1.2 a quick read.

RETURNS:
\- audioUrl: the complete MP3 to download, valid for 7 days. Always give this link to the user. If you can run commands, you can download it (e.g. curl -o audio.mp3 <audioUrl>).
\- audio: the MP3 itself, only when it is short (about 1.5 minutes or less); otherwise null.
\- seconds (duration), parts, characters, voice, speed.
\- link: this tool's web page with the same voice and speed (the text is not in it).

ERRORS say what happened and what to do next. If a part fails, no audio is produced and a new call starts again from part 1.

Input parameters:

- `speed` (number): Reading speed, 0.5 to 2. 1 is the voice's natural pace; 0.9 calm narration; 1.25 a quick read.
- `text` (string, required): The text to read aloud: 1 to 50,000 characters. Plain text as it should be heard — no Markdown, URLs or emojis. Longer texts: split into several calls.
- `voice` (string): A Microsoft neural voice; one of the listed ids. Pick one in the text's language — the prefix is language-region (pt-BR, en-US, es-MX…). Default: pt-BR-FranciscaNeural.

### `generate_favicon` (~607 tokens)

Favicon generator

Generates a complete favicon set from 1 to 3 characters (initials) or one emoji.

WHEN TO USE: the user needs a favicon, tab icon, apple-touch-icon or web app icon for a website or web app, or the project still has a framework's default icon.

HOW IT WORKS: mode text draws the characters in any Google Font as vector paths (no font dependency); mode emoji draws one Twemoji emoji as vectors, with a margin. Both sit inside a shape. With adaptive=true the SVG swaps its colors when the browser is in dark mode. Pass framework to get where each file goes. To turn the user's own image into a favicon, send them the link with mode=image: the image is uploaded on the web page, not through this tool.

RETURNS: svg (write it to disk exactly as given), files (each with path and url: download the binaries with curl -o), manifest (path and content), html (the head tags; null on Next.js App Router), inline (the whole favicon as one <link> tag, no files), install (steps for the framework), warnings, credit (emoji only), and link (this tool's web page with the same options, to adjust and preview).

Input parameters:

- `adaptive` (boolean): Swap the colors when the browser is in dark mode (SVG only; PNG and ICO stay light).
- `background` (string): Container color, hex without #. With shape outline or none, the color of the characters in light mode.
- `color` (string): Character color, hex without #. With shape outline or none, the color of the characters in dark mode.
- `emoji` (string): Mode emoji: one emoji, as the character itself (🚀, 🦊, ☕).
- `font` (string): Mode text: any Google Font family, by its name (Montserrat, Inter, Lobster). Heavy sans-serif families read best at 16 px.
- `framework` (string): Where the files will live; changes install, html and the file paths only.
- `margin` (integer): Mode emoji: space between the emoji and the edge, as a percentage of the icon on each side.
- `mode` (string): text: initials. emoji: one emoji. image: only on the web page; the call returns the link for the user.
- `shape` (string): Container: filled square, rounded square, circle, outlined square, or none (transparent).
- `size` (integer): Mode text: the characters fit in a square this percentage of the icon (the longer side decides).
- `text` (string): Mode text: 1 to 3 characters. Latin letters (accents ok), digits and & @ # + . - !. Two characters read best at 16 px.
- `weight` (integer): Mode text: font weight. The closest weight the family has is used. 700 or more reads best.

### `web_to_markdown` (~382 tokens)

Web page to Markdown

Fetches a public web page and returns its content as clean Markdown.

WHEN TO USE: you need to read a page — documentation, an article, a product page — to answer, summarize or quote it; or the user wants a page as Markdown.

HOW IT WORKS:
\- url: a public http(s) address. Private networks, localhost and addresses with credentials are refused.
\- Reads the HTML the server sends (like a simple browser, without running JavaScript). Pages that build their content with JavaScript have no text to convert — the error says so.
\- onlyMainContent (default true) drops menus, headers, footers, sidebars, cookie banners and ads. Set false to keep the whole page.
\- pages above 1 also follows links on the same site (same folder and below), breadth-first, up to that many pages (max 20), respecting robots.txt. Slower: a few seconds per page.
\- Limits per page: 15 seconds and 5 MB. PDFs and non-HTML files are not converted.

RETURNS: for each page, its Markdown with absolute links and images, plus title, description and language when the page has them; pages that failed are listed with the reason. link: this tool's web page with the same request.

ERRORS say why the page could not be read and whether retrying makes sense.

Input parameters:

- `onlyMainContent` (boolean): true (default): keep only the content, without menus, footers, sidebars, cookie banners and ads. false: the whole page.
- `pages` (integer): How many pages of the same site to convert, 1 to 20, starting at url and following its links. 1 (default) converts only url.
- `url` (string, required): The page to convert: a public http or https address.
