Papyrio PDF Tools

What Papyrio PDF Tools does

Papyrio PDF Tools exposes the Papyrio PDF API through the Model Context Protocol. It lets an MCP-compatible assistant work with files on the local machine using absolute paths. Operations include reducing PDF size, joining documents, separating pages, extracting existing text, converting between PDF and common document or image formats, adding OCR, rendering webpages, and applying or removing password protection.

The tool set supports workflows that combine several operations. For example, an assistant can OCR scanned invoices, merge the resulting PDFs, and compress the combined file as a sequence of tool calls. Output files are written locally, with most tools deriving a name from the input and adding a -papyrio suffix when output_path is omitted.

How it works

The MCP process receives tool requests from the assistant and makes corresponding requests to the Papyrio PDF API. Input and output locations are local absolute paths. Although the workflow is controlled from the local machine, the files are uploaded to the Papyrio API for processing in memory. The API discards them after returning the result.

The server can run without an API key through a guest tier limited to three operations per day per IP address. A RapidAPI key enables the paid API path; the free RapidAPI tier allows 50 requests per month and does not require a payment card.

Setup and configuration

For Claude Desktop, download the latest papyrio-mcp.mcpb release and open it to install the extension. The API key can be left empty for guest access or added later in the extension settings.

For a manual installation, configure the server with npx:

{
  "mcpServers": {
    "papyrio": {
      "command": "npx",
      "args": ["-y", "papyrio-mcp"]
    }
  }
}

Set PAPYRIO_API_KEY in the server's env object when using a RapidAPI key. The package can also be built locally with npm install and npm run build; a client can then launch dist/index.js with Node.js.

Tools and capabilities

• compress_pdf reduces PDF size, particularly for image-heavy documents.
• merge_pdfs joins between two and ten PDFs in the supplied order.
• split_pdf places each PDF page into a ZIP archive.
• extract_pdf_text returns the document's existing text layer as UTF-8.
• pdf_to_word creates an editable DOCX reconstruction.
• pdf_to_jpg renders PDF pages into a ZIP of JPG images.
• ocr_pdf adds searchable text to scans and accepts English, Russian, Spanish, Italian, Uzbek, or Kazakh language selection.
• office_to_pdf converts Word, PowerPoint, and Excel files to PDF.
• image_to_pdf places JPG, PNG, or WebP input into a PDF page.
• webpage_to_pdf renders a public URL with a headless browser.
• protect_pdf encrypts a PDF with AES-256, while unlock_pdf removes a password that is already known.

Limitations and notes

OCR handles up to 15 pages per call. webpage_to_pdf requires an explicit output_path because it has no input filename from which to derive one. Guest access is rate-limited, so multi-step testing may exhaust the daily allowance. The service is intended for public webpage URLs, and all file-processing operations send the files to the Papyrio API.
