211+ MCP tools for AI agents behind one API key: PDF (merge, split, compress, redact, fill forms), documents, text and developer utilities, 55 finance, tax and health calculators, plus image, audio and video conversion. Files are processed in memory and nothing is stored. Trial key with 20,000 calls/month at freedailypro.com/developers.
Scored across 240 tools
There are many overlapping tools: eight PDF compression variants, four PPTX compression levels, multiple unit converters (converters_units, converters_units_list, convert_length/temperature/weight), and several finance calculators that cover similar ground. The toolset prefixes help, but with 240 tools an agent faces a high risk of selecting the wrong near-duplicate.
Almost all names are snake_case and grouped with predictable toolset prefixes such as pdf_, image_, pptx_, audio_, business_, converters_, and validate_. A few vague or noun-only names (base64, hashtags, percentage, text_csv, converters_roman) and mixed verb/noun styles are minor deviations rather than a chaotic scheme.
240 tools is far beyond an appropriate single-server scope, even for a broad utility suite. The toolsets and search/list helpers mitigate this somewhat, but the count is an extreme mismatch and includes many redundant compression and calculator variants.
Coverage is very broad across PDF, PPTX, image, audio, video, finance, business documents, planning, validation, and text utilities. Some gaps remain, such as PDF text extraction/OCR, PDF-to-image, spreadsheet tools, and archive handling, but most core workflows have a tool.

Add page numbers to a PDF
Inputs: position (required), fileBase64 (required), format, prefix, +4 more.
Shrink a PDF. Default aims for about 50% smaller: tidies structure first (text untouched), then shrinks pictures only as much as needed. level: auto (default), medium, strong. targetFileSize (such as 2MB or 500KB) is the size to end at, for auto; default is half the original.
Inputs: fileBase64 (required), level, targetFileSize.
Shrink a PDF harder (the site's Aggressive mode): Balanced steps, then pages become pictures at finer and finer steps, converting a page only when that is clearly smaller. Text on converted pages is no longer selectable (textSelectable says which). Slow: several seconds per page; returns the best level finished (truncated: true) if the time budget runs out. Errors if the PDF is unreadable, password-protected, over 100 pages or cannot be made smaller.
Inputs: fileBase64 (required).
Shrink a PDF the gentle way (the site's Balanced mode): tidy the file, empty blank pages, and re-save the pictures inside at about 140 dpi. Text stays selectable; links, bookmarks, form fields and page sizes are kept. Returns the smaller file plus the levels applied. Errors if the PDF is unreadable, password-protected, over 100 pages, or if nothing gets smaller (for example a PDF that is already mostly text); in that case try pdf_compress_aggressive.
Inputs: fileBase64 (required).
Shrink a PDF as far as it will go (the site's Extreme mode): Aggressive steps, then every page as 70 dpi greyscale and as black-and-white JBIG2, keeping the smallest. Colour is lost and text is no longer selectable; in tiny print a letter can rarely be swapped for a look-alike, so check important numbers in the original. Slow; returns the best level finished (truncated: true) on timeout. Errors if the PDF is unreadable, password-protected, over 100 pages or cannot be made smaller.
Inputs: fileBase64 (required).
Shrink a scanned PDF by turning pages into 100 dpi greyscale JPEG pictures: shading and photos are kept, colour is dropped, text on converted pages is no longer selectable. Larger than the black-and-white files but nothing is thresholded to pure black and white. A page is converted only when that makes it at least 10% smaller. Errors (nothing is returned) if the result would not be smaller than the original, or if the PDF is unreadable, password-protected or over 100 pages.
Inputs: fileBase64 (required), dpi.
Shrink a scanned PDF by turning pages into pure black-and-white JBIG2 pictures, each page coded exactly as read (no letter is ever swapped; safe for contracts and numbers). Colour and shading are lost and text on converted pages is no longer selectable. A page is converted only when that makes it at least 10% smaller; other pages (for example real-text pages) are copied untouched. Errors if the PDF is unreadable, password-protected, over 100 pages or cannot be made smaller.
Inputs: fileBase64 (required), dpi.
Shrink a PDF to a size you need, for example under 2 MB (the site's File size mode). Runs Balanced, Aggressive and Extreme gentlest first and stops at the first that fits; otherwise returns the smallest file with targetMet: false and limitReason. limit caps how far it goes (balanced keeps text selectable). Slow at stronger limits; returns the best level so far (truncated: true) on timeout. A PDF already under the goal comes back unchanged.
Inputs: fileBase64 (required), targetSize (required), limit.
Shrink a scanned PDF to the smallest black-and-white file with JBIG2 symbol mode (letter shapes stored once, typically 3x smaller than lossless black-and-white). A letter can rarely be swapped for a look-alike (6 and 8 in tiny print): check important numbers. Colour is lost and text on converted pages is no longer selectable. A page converts only if it gets at least 10% smaller. Errors if the PDF is unreadable, password-protected, over 100 pages or no smaller file results.
Inputs: fileBase64 (required), dpi, threshold.
Extract specific pages from a PDF into a new PDF
Inputs: pages (required), fileBase64 (required).
Fill a PDF form's fields — sets text, checkbox, dropdown, radio and option-list values and returns the filled PDF as base64 in the first text item, optionally flattened so it can no longer be edited.

Inputs: fileBase64 (required).
Permanently redact areas of a PDF. Boxes are fractions (0 to 1) of the page as displayed, measured from the top-left corner, pages numbered from 0. Text characters, picture pixels, vector art and annotations under a box are removed from the file itself and an opaque black bar is drawn; everything outside the boxes stays real, selectable text in its original fonts. A page that cannot be edited exactly (for example a curved drawing partly under a box) is turned into a picture with the boxes painted black instead. Pages without boxes are not touched
Inputs: boxes (required), fileBase64 (required).

Find and replace text across every slide of a PowerPoint (.pptx), and get the edited .pptx back (base64). Matches inside a paragraph are replaced even when PowerPoint split the words into several runs; the formatting of the first run is kept. Speaker notes are searched too (includeNotes, default true); the slide master and layouts only when includeTemplate is true. Errors with 422 when nothing matches, so a wrong spelling is noticed.
Inputs: find (required), fileBase64 (required), replace, matchCase, +4 more.
List every font a PowerPoint (.pptx) uses, as JSON: name, how many places use it, which slides, whether the master/layouts/theme use it, whether it is the theme's heading or body font and whether it is embedded. Use it before pptx_replace_fonts.
Inputs: fileBase64 (required).
Turn a PowerPoint (.pptx) into ONE self-contained HTML file (returned as text): the slides as readable text with their pictures inlined, arrow-key navigation, a grid (G) and optional speaker notes (N). No external files or scripts. Charts, SmartArt, video, audio and animations are not carried over (notCarried lists them). Speaker notes are off unless includeNotes is true; hidden slides are left out unless includeHidden is true.
Inputs: fileBase64 (required), look, title, includeNotes, +1 more.
Merge two or more PowerPoint (.pptx) files into one editable presentation (base64), slides in the order the files are given. Each deck keeps its own master, layouts and theme (several masters in one file), so slides keep the look they came with; set useFirstDesign true to put later decks on the first deck's layouts when they match by name. All decks must have the SAME slide size: otherwise it errors (422) naming the decks and their sizes, so fix the size first (in PowerPoint: Design, Slide Size). Comments of the second and later decks are left out. Up to 10 decks and 100 MB in all.
Inputs: files (required), useFirstDesign.
Reorder, delete and duplicate the slides of a PowerPoint (.pptx), returning a new editable .pptx (base64); the slide master, layouts and theme stay as they were and every slide keeps its notes, pictures, charts and tables. order: the final order as 1-based slide numbers, for example [3,1,2] (a number twice makes a copy). remove: slides to delete. duplicate: slides to copy, the copy placed right after the original. removeHidden: delete every hidden slide. Slide numbers always refer to the ORIGINAL deck. Errors when a number does not exist or every slide would be removed.
Inputs: fileBase64 (required), order, remove, duplicate, +1 more.
Black out sensitive text in a .pptx and get the redacted file (base64). Covers slides, notes, master and layouts, charts, SmartArt, comments, alt text and link targets. presets: email, phone, ssn, card, url, ip, money, date; also terms, regexes, imageSlides and imageByAlt; stripNotes, stripComments and stripMetadata remove those entirely. The result is re-read and any remaining match is reported (remaining, remainingWhere). Text inside pictures, video and audio cannot be found; warnings say what was not checked.
Inputs: fileBase64 (required), notes, terms, presets, +9 more.
Try to repair a damaged PowerPoint (.pptx) that PowerPoint reports as needing repair or will not open, and get a new .pptx (base64) plus what was fixed and what was lost. Mends a missing or wrong file list, a missing or inconsistent slide list, dead links to pictures, charts and layouts, duplicate slide ids and a damaged zip index; pieces that cannot be saved are dropped and listed. A healthy file is returned unchanged with changed false. Cannot open password-protected files or old .ppt files.
Inputs: fileBase64 (required).
Swap fonts across a PowerPoint (.pptx) and get the new .pptx (base64): slides, notes, layouts, masters, the theme's heading and body fonts, charts and SmartArt. mapping is {"Old font": "New font"}. Embedded copies of replaced fonts are removed. Errors (422) when none of the named fonts is used. Text is not resized, so a wider font can make a line wrap.
Inputs: mapping (required), fileBase64 (required).
Change the slide size of a PowerPoint (.pptx) and scale the content to match, returning the new .pptx (base64). preset 16x9, 4x3, 16x10, a4 or letter, or width and height with a unit. mode fit (default) keeps the shape of the content and centres it; fill covers the new area; stretch changes the shape. Fonts, line widths and spacing scale with the content unless scaleText is false. The result lists how many shapes now reach outside the slide. Errors (422) when the slides are already that size.
Inputs: fileBase64 (required), mode, unit, width, +3 more.
Add slide numbers to a PowerPoint (.pptx), or remove them, and get the new .pptx (base64). The numbers are real slide-number fields, so they follow when slides move. Slides that already have a number are left alone. 'of-total' writes the total as plain text (PowerPoint has no total field). mode remove takes off the numbers the slides themselves carry (not those on the master).
Inputs: fileBase64 (required), mode, size, color, +4 more.
Split a PowerPoint (.pptx) into several presentations, returned as ONE ZIP (base64) of .pptx files, each a complete editable deck keeping its own slides' notes, pictures, charts and tables. mode: each (one file per slide; default), every (every N slides, give every), or range (ranges such as '1-3,5,8-': one file per range, or one file with all of them when rangesAsFiles is false). At most 100 files. Errors name the slide numbers that do not exist.
Inputs: fileBase64 (required), mode, every, ranges, +2 more.
Turn a PowerPoint (.pptx) into a .potx template (base64) and optionally change its theme: colors is {dk1, lt1, dk2, lt2, accent1..accent6, hlink, folHlink} as six-digit hex, plus headingFont, bodyFont and the theme name. keepSlides all, first or none. format pptx gives a re-themed deck instead. Shapes with their own fixed colour or font do not follow the theme; fixedColorShapes and fixedFontRuns count them. The .potx has been checked in LibreOffice, not in desktop PowerPoint.
Inputs: fileBase64 (required), name, colors, format, +4 more.
Stamp a text watermark (such as DRAFT or CONFIDENTIAL) or a picture on the slides of a PowerPoint (.pptx), or remove the watermarks this tool made, and get the new .pptx (base64). Give text, or pictureBase64 (PNG or JPEG) for a picture. It sits behind the slide content by default.

55 stateless calculators for AI agents: loans and mortgage amortization, income and sales tax, retirement and FIRE, BMI and health, date and planning, and unit conversions, returned as clean JSON. Nothing is stored. Part of FreeDailyPro's 211+ MCP tools; trial key with 20,000 calls/month at freedailypro.com/developers.
111 tools for AI assistants, so an answer comes from a rule instead of a guess. 84 deterministic utilities. IBAN and VAT validation, cron parsing, regex testing, hashing, JWT decoding, conversion between JSON, CSV, XML and YAML, units, number bases, timezones and date arithmetic. Eleven of them encode Dutch rules that a model tends to get wrong: AOW pension age, inheritance and gift tax, unemployment benefit duration, notice period, severance, the 30 percent ruling, holiday allowance, mileage allowance, and public and school holidays. Five more generate test data that is structurally valid and belongs to nobody: BSN, IBAN, BRP person records, UPA pension files and document numbers. 14 render tools that return a hosted file. HTML or a live URL to PDF, full page screenshots, QR codes, PDF merge and split, images to PDF, image resize, convert and compress, metadata stripping, PDF to DOCX and back. Plus read_page, which returns the readable content of a JavaScript rendered page as Markdown. 4 memory tools give an agent key-value state that survives between sessions, scoped to its own API key. 3 workflow tools list and run saved multi-step workflows on the caller's account. 6 AI tools for the jobs where a model is the right instrument rather than the wrong one: check a message for scam patterns, write a spreadsheet formula, turn a question into SQL, translate code between languages, improve a prompt, draft an email. Utilities and memory are free. Renders and AI tools have a free tier and credit packs. Workflows need an API key, because a workflow belongs to an account rather than to a key.
