UUTOOLS converter in Claude and other AI assistants
An MCP connector: ask your assistant to convert a picture or a document, and it gives you a download link – free, with a daily limit.
Connector address
Set it up
Claude (web, desktop and mobile apps)
- Open Settings → Connectors and choose “Add custom connector” (offered on Claude plans with custom connectors).
- Name it “UUTOOLS” and paste the connector address below.
- Click Connect: our page opens – sign in or create a free account and allow access. No key to copy.
- Done. In a chat, attach a file or paste a link and ask, e.g. “Convert this to JPG”.
Claude Code (terminal)
Create a key on your account page, then run:
Other MCP clients and your own code
Any client that talks to remote MCP servers over HTTP can use the connector address with your key as “Authorization: Bearer uut_…”. Apps that cannot send a header can put the key at the end of the address: /mcp/convert/uut_…
What it does
- Pictures: JPG, PNG, WebP, HEIC, AVIF, GIF, BMP, TIFF, ICO and SVG to other picture formats – also resized, rotated, flipped or compressed to a size in KB.
- Documents, e-books and spreadsheets: Word, PDF, ODT, RTF, TXT, Markdown, HTML, EPUB, MOBI, AZW3, XLSX, CSV, PowerPoint, Keynote and more – the same pairs as our document converters.
- Audio: WAV, MP3, M4A, FLAC, OGG, OPUS, WMA, AAC, AIFF and more to other audio formats – with bitrate, mono/stereo or a cut.
- The result comes as a link to our download page; the file is deleted automatically after a few hours.
- Free, with a daily number of files per key and small files (up to 10 MB each).
What you can ask
- “Convert this HEIC photo from my iPhone to JPG.”
- “Make this PNG a WebP, at most 1200 pixels wide.”
- “Compress this picture to under 200 KB.”
- “Turn this DOCX into a PDF/A.”
- “Convert this EPUB to MOBI for my Kindle.”
Tools of the connector
- list_formats
- Which formats can become which, and the limits left today.
- convert_image
- A picture to another format, optionally resized, rotated or compressed.
- convert_document
- A document, e-book, spreadsheet or drawing to another format.
- convert_audio
- A sound file to another audio format, optionally with a bitrate, mono/stereo or cut.
- get_conversion
- The state of a running conversion, then the download link.
Limits and privacy
Each key may send 100 files a day, up to 10 MB each. Files are converted on our server like every server conversion on the site and deleted automatically after a few hours; for each file we only count its format, size and time – never its name or contents. We do not see your chat with the assistant.
Frequently asked questions
What is MCP?
The Model Context Protocol is an open standard that lets AI assistants such as Claude use outside tools. Our connector is such a tool: the assistant sends it a file and gets back a download link.
Does it cost anything?
No. The account and the connector are free; each key has a daily number of files and a maximum file size.
Do I need an API key?
Not in Claude’s apps: there you sign in once and allow access. A key is only needed for Claude Code, other clients and your own code – you create it on your account page.
Why do I get a link instead of the file?
The assistant passes the file to our server, and you save the result from our download page – like every other download on the site. The link works until the file is deleted after a few hours.
Can it convert videos?
Not through the connector – video files are too large to pass through an assistant. Audio works; videos are converted on the site itself.
