Click on "Deploy Server".
Wait a few minutes for the server to deploy. Once ready, it will show a "Started" state.
In the chat, type @ followed by the MCP server name and your instructions, e.g., "@Formatika MCP Convert all HEIC files to JPEG in this folder"
That's it! The server will respond to your query, and you can continue using it as needed.
Here is a step-by-step guide with screenshots.
Convert, resize, compress, crop and rotate files straight from your agent, using formatika.app.
Your agent gets the tools; the files stay on your machine until a job needs them and come back as soon as it is done.
No installation and no account needed to start:
npx @formatika/mcpclaude mcp add formatika -- npx -y @formatika/mcpAdd this to the MCP servers section of the client configuration:
{
"mcpServers": {
"formatika": {
"command": "npx",
"args": ["-y", "@formatika/mcp"]
}
}
}On Windows, Claude Desktop launches the server without a shell and cannot find
npx directly. Use this instead:
{
"mcpServers": {
"formatika": {
"command": "cmd",
"args": ["/c", "npx", "-y", "@formatika/mcp"]
}
}
}Fully restart the client after editing the configuration.

The tool list comes from the service at start-up, so it never lags behind what formatika can actually do — this README does not have to be updated for a new tool to appear in your agent.
Today that is images, audio, video, PDF, archives, subtitles and tables: over thirty tools. The current list, with what each one does, is at formatika.app/mcp.
Every tool takes paths — one or more files — and an optional outputDir.
Results are written next to the source file unless you say otherwise, and
existing files are never overwritten: a name that is taken gets a number.
Without a key you get a daily allowance, which is enough for occasional work. For volume, create a key at formatika.app/account and pass it in:
{
"mcpServers": {
"formatika": {
"command": "npx",
"args": ["-y", "@formatika/mcp"],
"env": { "FORMATIKA_API_KEY": "fk_..." }
}
}
}FORMATIKA_URL points the server somewhere else — useful if you run formatika
yourself.
Files are processed and deleted: two hours without an account, twenty-four hours with one. They are not looked at, not shared and not used to train anything. See the privacy policy.

This is a read-only mirror of the packages/mcp directory of the formatika
monorepo, published so that the package has a public home: catalogues link to
it, and people who read code before installing it can do so.
Pull requests here cannot be merged — the next sync would overwrite them. Issues, however, are read and welcome: bugs, missing tools, awkward APIs.

Unzip files. Get the files out of an archive. Paths like "../.." are defused, and an archive that expands out of all proportion to its size is refused. Accepts application/zip, application/x-zip-compressed, .zip; up to 100 MB per file.
Inputs: paths (required), outputDir.
Create a ZIP. Put several files into one archive so you can send them as a single attachment. Packed in the browser — the files never reach a server. Accepts /; up to 100 MB per file.
Inputs: paths (required), level, outputDir.
Audio converter. Convert audio between MP3, AAC, OPUS, FLAC, WAV and OGG. Pick a bitrate, drop it to mono, change the sample rate. Accepts audio/*, .m4a, .opus, .aac, .wma; up to 200 MB per file.
Inputs: paths (required), format (required), mono, outputDir, +2 more.
Extract audio from video. Pull the soundtrack out of a video file. When the track can be lifted as is, nothing is re-encoded and nothing is lost. Accepts video/*, .mkv, .webm, .mov, .avi, .m4v; up to 500 MB per file.
Inputs: paths (required), format, outputDir, bitrateKbps.
Merge audio. Join several recordings into one, in the order you picked. Matching files are joined without re-encoding — instantly and with no quality lost. Accepts audio/*, .m4a, .opus, .aac; up to 200 MB per file.
Inputs: paths (required), format, outputDir, bitrateKbps.
Normalize loudness. Even out loudness to the EBU R128 broadcast standard, in two passes — so the recording does not breathe. Accepts audio/*, .m4a, .opus, .aac; up to 200 MB per file.
Inputs: paths (required), target, truePeak, outputDir.
Trim silence. Cut the silence at the start and the end of a recording. Pauses inside are left alone — in speech they carry meaning. Accepts audio/*, .m4a, .opus, .aac; up to 200 MB per file.
Inputs: paths (required), keepMs, outputDir, thresholdDb.
Edit audio tags. Change the title, artist and album. The audio itself is copied untouched, so nothing is lost and it takes no time. Accepts audio/*, .m4a, .opus, .aac; up to 200 MB per file.
Inputs: paths (required), year, album, clear, +3 more.
Trim audio. Cut a fragment out of a recording by timecodes. By default the stream is copied, so the cut costs no quality. Accepts audio/*, .m4a, .opus, .aac; up to 200 MB per file.
Inputs: paths (required), end, fade, start, +2 more.
CSV, JSON and YAML. Convert a table from one format to another. Commas and line breaks inside fields do not break the parser. Runs in the browser — the data stays with you. Accepts text/csv, text/tab-separated-values, application/json, application/yaml, text/yaml, .csv, .tsv, .json, .yaml, .yml; up to 20 MB per file.
Inputs: paths (required), format, outputDir.
Documents to PDF. Word, Excel and PowerPoint to PDF so the layout survives the trip. Takes docx, xlsx, pptx as well as older doc, xls, ppt and open odt, ods, odp. Accepts application/vnd.openxmlformats-officedocument.wordprocessingml.document, application/vnd.openxmlformats-officedocument.spreadsheetml.sheet, application/vnd.openxmlformats-officedocument.presentationml.presentation, application/msword, application/vnd.ms-excel, application/vnd.ms-powerpoint, application/vnd.oasis.opendocument.text, application/vnd.oasis.opendocument.spreadsheet, application/vnd.oasis.opendocument.presentation, application/rtf, .docx, .xlsx, .pptx, .doc, .xls, .ppt, .odt, .ods, .odp, .rtf, .txt; up to 50 MB per file.
Inputs: paths (required), archival, outputDir.
Document for sending. Word, Excel or a deck becomes a PDF and is compressed right away — so the attachment fits through mail and the layout survives the trip. Accepts application/vnd.openxmlformats-officedocument.wordprocessingml.document, application/vnd.openxmlformats-officedocument.spreadsheetml.sheet, application/vnd.openxmlformats-officedocument.presentationml.presentation, application/msword, application/vnd.ms-excel, application/vnd.ms-powerpoint, application/vnd.oasis.opendocument.text, application/vnd.oasis.opendocument.spreadsheet, application/vnd.oasis.opendocument.presentation, application/rtf, .docx, .xlsx, .pptx, .doc, .xls, .ppt, .odt, .ods, .odp, .rtf, .txt; up to 50 MB per file.
Inputs: paths (required), outputDir.
Compress image. Make a photo lighter — down to a size limit or by quality. Handy when a form refuses a large file. Accepts image/*, .heic, .heif, .avif; up to 50 MB per file.
Inputs: paths (required), format, quality, maxWidth, +2 more.
Image converter. Convert images between JPG, PNG, WebP, AVIF and HEIC. Resize and strip EXIF along the way. Accepts image/*, .heic, .heif, .avif; up to 50 MB per file.
Inputs: paths (required), format (required), resize, quality, +2 more.
Crop image. Cut a photo to a ratio — square for an avatar, 16:9 for a cover. Nothing gets scaled down. Accepts image/*, .heic, .heif, .avif; up to 50 MB per file.
Inputs: paths (required), aspect, format, quality, +2 more.
Photo for a website. Strips the geotag and camera data, fits the long side into 1600 pixels and encodes WebP. One step instead of three settings. Accepts image/*, .heic, .heif, .avif; up to 50 MB per file.
Inputs: paths (required), outputDir.
Remove EXIF and location. Strip the camera model, the date and — most importantly — the coordinates from a photo. JPEG and PNG are cleaned byte by byte, so the picture itself is not touched. Accepts image/*, .heic, .heif, .avif; up to 50 MB per file.
Inputs: paths (required), keepIcc, outputDir.
Colour palette from an image. Pull the main colours out of a picture and get ready-made CSS variables. Runs in your browser: the photo never leaves it. Accepts image/*, .heic, .heif, .avif; up to 50 MB per file.
Inputs: paths (required), colors, outputDir.
Resize image. Change the dimensions of a photo or picture. Fits within your numbers without enlarging. Accepts image/*, .heic, .heif, .avif; up to 50 MB per file.
Inputs: paths (required), fit, width, format, +3 more.
Rotate image. Turn a photo by 90, 180 or 270 degrees, or mirror it. Sideways phone shots get fixed. Accepts image/*, .heic, .heif, .avif; up to 50 MB per file.
Inputs: paths (required), angle, format, outputDir, +2 more.
Compress PDF. Make a PDF lighter by re-encoding the images inside it. If the result is not meaningfully smaller, you get the original back — untouched. Accepts application/pdf, .pdf; up to 100 MB per file.
Inputs: paths (required), preset, grayscale, outputDir.
Images to PDF. Turn photos and scans into one PDF, in the order you picked. HEIC from an iPhone works too. Accepts image/*, .heic, .heif, .avif; up to 50 MB per file.
Inputs: paths (required), quality, marginMm, pageSize, +1 more.
Merge PDF. Join several PDF files into one, in the order you picked. Nothing is re-rendered: pages are copied as they are. Accepts application/pdf, .pdf; up to 100 MB per file.
Inputs: paths (required), outputDir, keepMetadata.
Rotate and delete PDF pages. Turn pages that were scanned sideways and drop the ones you do not need — in one pass over the document. Accepts application/pdf, .pdf; up to 100 MB per file.
Inputs: paths (required), remove, rotate, outputDir, +1 more.
Split PDF. Pull pages out of a PDF — a range, a few ranges, or every page as its own file. Accepts application/pdf, .pdf; up to 100 MB per file.
Inputs: paths (required), mode, pages, outputDir.
PDF to images. Turn PDF pages into JPG or PNG — one image per page. Handy when the document has to be shown where PDF is not opened. Accepts application/pdf, .pdf; up to 100 MB per file.
Inputs: paths (required), dpi, pages, format, +1 more.
Convert subtitles. Turn SRT into VTT and back, and shift the timings while you are at it. Runs in your browser — it is text, nothing needs a server. Accepts .srt, .vtt, text/vtt, text/plain, application/x-subrip; up to 5 MB per file.
Inputs: paths (required), format, shiftMs, outputDir.
File to base64 and back. Encode a file as base64 — to paste an image straight into CSS, say — or decode a base64 string back into a file. The direction is worked out for you. Accepts /; up to 20 MB per file.
Inputs: paths (required), dataUri, outputDir, lineBreaks.
File checksum. Work out the MD5, SHA-1, SHA-256 or SHA-512 of a file to check that what you downloaded is what was published. The file never leaves your device. Accepts /; up to 500 MB per file.
Inputs: paths (required), algorithm, outputDir.
Compress video. Fit a recording into a given number of megabytes — to send by email or messenger. We work out the bitrate for your limit and encode in two passes to hit it. Accepts video/*, .mp4, .mov, .mkv, .webm, .avi, .m4v; up to 500 MB per file.
Inputs: paths (required), targetMb, audioKbps, outputDir.
Convert video. Turn a video into MP4, WebM or MKV. MP4 plays everywhere, WebM is for the web, MKV is what you usually need to open somewhere else. Accepts video/*, .mp4, .mov, .mkv, .webm, .avi, .m4v; up to 500 MB per file.
Inputs: paths (required), speed, format, quality, +1 more.
Video for a messenger. Squeezes the recording to 24 megabytes — a size that passes both mail and messengers. The bitrate is computed for your file; the audio stays. Accepts video/*, .mp4, .mov, .mkv, .webm, .avi, .m4v; up to 500 MB per file.
Inputs: paths (required), outputDir.
Remove audio from video. Drop the sound track. The picture is copied as is — no quality loss and no waiting. Accepts video/*, .mp4, .mov, .mkv, .webm, .avi, .m4v; up to 500 MB per file.
Inputs: paths (required), outputDir.
Resize video. Convert a recording to 1080p, 720p, 480p or 360p. Width follows the original proportions, so nothing gets stretched. Upscaling is refused: it adds no detail and only inflates the file. Accepts video/*, .mp4, .mov, .mkv, .webm, .avi, .m4v; up to 500 MB per file.
Inputs: paths (required), height, quality, outputDir.
Add subtitles to video. Burn subtitles into the picture or attach them as a track. Burned-in subtitles show everywhere, even where nobody turns them on; attached ones the viewer can switch off, and the picture is not re-encoded. Accepts video/*, .mp4, .mov, .mkv, .webm, .srt, .vtt, .ass, .ssa; up to 500 MB per file.
Inputs: paths (required), mode, fontSize, outputDir.
Video thumbnail. Grab a frame for a cover or preview. Exactly one frame is decoded, so an hour of video costs no more than a minute. Accepts video/*, .mp4, .mov, .mkv, .webm, .avi, .m4v; up to 500 MB per file.
Inputs: paths (required), at, width, format, +1 more.
Video to GIF. Build a GIF from a fragment. The palette is generated for your specific video in a separate pass — without that you get noise instead of a picture. Accepts video/*, .mp4, .mov, .mkv, .webm, .avi, .m4v; up to 500 MB per file.
Inputs: paths (required), fps, from, width, +2 more.
Trim video. Cut out a fragment by timecodes. The stream is copied without re-encoding, so it is fast and lossless. If the cut cannot land on a keyframe, we re-encode and say so. Accepts video/*, .mp4, .mov, .mkv, .webm, .avi, .m4v; up to 500 MB per file.
Inputs: paths (required), to, from, precise, +1 more.

Scored across 38 tools
Most tools have clearly distinct purposes, but some overlap exists between compound workflows like video_compress and video_for-messenger, or image_compress and image_for-web. Descriptions help clarify the differences, so ambiguity is low overall.
The naming pattern is mostly category_action (video_convert, pdf_merge), but inconsistency arises with dashes in names like video_to-gif, pdf_from-image, and audio_silence-trim, plus a few noun-noun names like pdf_pages and video_subtitles. This mixed style is still readable but not fully consistent.
38 tools is excessive for an MCP server, even if the domain spans multiple media types. The count feels overwhelming, especially with several compound workflow tools (e.g., video_for-messenger, image_for-web) that could be composed from existing primitives.
The tool set provides broad coverage across video, audio, image, PDF, document, archive, and data transformations, with useful utilities like hash and base64. Minor gaps exist, such as lack of video merging or video rotation, but the surface is largely comprehensive for common file conversion tasks.
