A free Model Context Protocol (MCP) server that lets Claude, Cursor, VS Code, Windsurf and other AI agents convert, compress, merge, split and edit PDFs — and convert between 100+ file formats (Word, Excel, PowerPoint, JPG, PNG, HEIC, ebooks, and more), right on your own machine. Powered by GuruPDF.

- 🗂️ 126 tools — PDF ⇄ Word/Excel/PowerPoint, images, ebooks, OCR, compress, merge, split, rotate, protect, watermark, and more.
- 💻 Works on your local files — reads and writes files on disk, no manual upload/download.
- 🆓 Free to start — every account gets daily credits. No credit card required.

| Tool | What it does |
|---|
convert_file | Convert/process a local file (or URL). Give it an input and a target format (pdf, png, docx…) or a tool slug (compress-pdf, merge-pdf…). Saves the result to disk. |
get_status | Check a conversion job by id and download the result when ready (for long jobs like video). |
list_conversions | List supported conversions/tools, optionally filtered by an input format. |
check_credits | Show remaining credits and how to get more. |
Examples
"Compress ~/Documents/report.pdf."
→ convert_file(input: "~/Documents/report.pdf", to: "compress-pdf")
"Convert invoice.docx to PDF."
→ convert_file(input: "invoice.docx", to: "pdf")
"Merge a.pdf and b.pdf into one."
→ convert_file(input: ["a.pdf", "b.pdf"], to: "merge-pdf")
"Password-protect this PDF with hunter2."
→ convert_file(input: "secret.pdf", to: "protect-pdf", options: { password: "hunter2" })
"Save this web page as a PDF: https://example.com"
→ convert_file(input: "https://example.com", to: "url-to-pdf")
Free tier & credits
Each tool costs a few credits. Free accounts get daily credits (refreshed every day) and 2 conversions/minute, 10/day. When you run out, the assistant will tell you — you can wait for the daily refresh or top up / upgrade. Conversions run on GuruPDF's servers; files are deleted automatically within an hour.
