Convert Fleet MCP Server

Describe a file job in plain English and get the Convert Fleet tools that do it, ranked, each with example arguments you can send straight back.

The Convert Fleet manual as Markdown: overview, per-tool reference, multi-step recipes, error handling and connection setup.

Convert a file between any of Convert Fleet's 178+ supported formats (documents, images, audio, video, e-books, archives, fonts, spreadsheets). Provide the input as a public file_url (preferred) or inline file_base64 + filename, and the target_format (e.g. 'pdf', 'mp3', 'docx', 'webp'). Returns a short-TTL signed download URL for the converted file. Use list_supported_formats first if unsure a target is valid.

Reduce a file's size while keeping its format and reasonable quality. Best for images (png/jpg/jpeg/webp/gif) and media (mp4/mp3/wav) — the file is re-encoded at a smaller size. Provide file_url or file_base64 + filename.

Run a PDF operation: merge several PDFs, split into pages, rotate, delete-pages, extract-pages, number-pages, watermark, or protect. For 'merge' pass file_urls[] or file_base64s[]; for everything else pass a single file_url or file_base64. 'split' returns the pages as base64; the other operations return a signed download URL.

Run FFmpeg on a media file (transcode, trim, scale, extract audio, change frame rate, make a thumbnail, etc.). Pass the input as file_url or file_base64 + filename, the FFmpeg arguments that go AFTER the input in 'args' (e.g. '-vf scale=1280:720 -c:v libx264' or '-vn -ab 192k'), and the output_format (e.g. 'mp4', 'mp3', 'gif'). The server runs: ffmpeg -i <input> <args> output.<output_format>. Shell metacharacters and network/file protocols are blocked.

Blur, pixelate or black out part of a video — or all of it. Pass the input as file_url or file_base64 + filename. Set mode='regions' (default) with 'regions' to cover only certain areas, mode='whole' to blur every pixel of every frame, or mode='whole-except' to blur everything BUT the listed areas. 'regions' is a JSON array string of boxes measured as fractions of the frame: [{"x":0.35,"y":0.12,"w":0.2,"h":0.25}] puts a box 35% across and 12% down, a fifth of the frame wide. Per area you can also set shape (rect|ellipse), style (blur|pixelate|fill), strength (1-100), feather (0-100), start/end in seconds, and track — [{"t":0,"x":0.1,"y":0.4},{"t":6,"x":0.7,"y":0.4}] — so the area follows a subject that moves. Values above 1 are read as pixels instead of fractions. Returns an mp4 at the source size, frame rate and duration with the audio kept.

Trim a video or audio file: keep the part between a start and an end time and drop the rest. Use it to cut off an intro, cut off an ending, or pull one clip out of the middle. Pass the input as file_url or file_base64 + filename. 'start' is where the kept part begins and 'end' is where it stops — both accept seconds (12.5) or a clock time ('1:05', '00:01:05.250'). Omit start to keep from the very beginning; omit end to keep through to the end of the file; give at least one of them. 'duration' is an alternative to end (keep that many seconds from start) and is ignored if end is given. An end past the file length is clamped to the real end rather than failing. When the cut starts at 0 — or the input is audio-only — nothing is re-encoded: the result is bit-for-bit the source, produced almost instantly, and keeps the container that was uploaded. A cut starting between keyframes is re-encoded so it begins on exactly the requested frame, and a video re-encode comes back as MP4. A lossless cut ends on a packet boundary, so it can run up to ~0.15s longer than asked.

Return the catalogue of input/output formats Convert Fleet supports, grouped by category, so you can choose a valid target_format for convert_file. Optionally pass 'from' to echo whether a given source format is recognised.

Return the caller's Convert Fleet plan (free/premium/enterprise) and remaining credits for the current period.

Split a PDF into one file per page. Each page comes back as its own short-TTL signed download URL.

Break a long HTML document into separate files — by heading level, by a custom delimiter, or by page break. Each section comes back as its own signed download URL.

Render a live web page (by URL) or a string of HTML into a PDF, the way a browser would draw it.

Extract the picture from the END of a video as an image — the very last frame, or a chosen number of seconds before the end.

Make a video last an exact number of seconds. New in-between frames are synthesised by motion interpolation, so a stretched clip still moves smoothly instead of stuttering on held frames; audio is tempo-stretched at its original pitch.
