What is the Paplume MCP server?

A free, standard Model Context Protocol server at https://pdfsuite.zalize.com/mcp that lets AI agents like Claude, Codex and Cursor merge, split, rotate, compress and edit PDFs directly — no API key or signup required.

Which tools are available over MCP?

merge_pdfs, split_pdf, rotate_pdf, remove_pages, compress_pdf, add_watermark, add_page_numbers, edit_metadata and flatten_pdf. Rendering-based conversions and AI features remain browser-only.

MCP Server · free & open

Merge, split, rotate, compress — a PDF MCP server your AI agent calls directly

Q: Is the PDF MCP server free?

Yes. Calls are anonymous with a small daily per-IP quota drawn from the same IP pool as the website (with a stricter cap on the MCP side); failed calls are automatically refunded.

Paplume ships a standard MCP (Model Context Protocol) server. Claude, Codex, Cursor and any MCP-capable agent can merge, split, compress and rotate PDFs with one line of config — anonymous, free, no API key.

Endpoint:POST https://pdfsuite.zalize.com/mcp

claude_desktop_config.json

{
  "mcpServers": {
    "pdf-suite": {
      "type": "http",
      "url": "https://pdfsuite.zalize.com/mcp"
    }
  }
}

Standard protocol

Built on the official MCP TypeScript SDK: a stateless Streamable HTTP endpoint that plugs into any MCP client.

Zero friction

Anonymous calls — no signup, no API key. Each tool has a daily free per-IP quota drawn from the same IP pool as the website (with a stricter cap on the MCP side).

Failures refunded

Only successful operations consume quota; failed calls are refunded automatically (up to a daily refund allowance). Quotas reset at 00:00 UTC.

Honest limits

Rendering-based conversions (PDF to image / OCR) and AI features stay browser-only — where files are processed locally on-device.

Why let your agent call MCP directly?

Stay in the conversation

Merge, split and compress right inside Claude / Cursor — no switching to a website, no upload/download round-trips.

Composable

Multi-step PDF pipelines (split → watermark → compress) are chained by the agent automatically — one sentence is enough.

Zero setup cost

No API key, no signup — one JSON snippet connects you; refund semantics match the website (quota draws from the same IP pool, with a stricter MCP cap).

Setup (Claude / Codex / Cursor)

Add this entry to your MCP client configuration:

{
  "mcpServers": {
    "pdf-suite": {
      "type": "http",
      "url": "https://pdfsuite.zalize.com/mcp"
    }
  }
}

Available tools (9)

Tool	Use when you want to…
merge_pdfs	combine 2–10 PDFs into one
split_pdf	extract a page range (1-based, inclusive)
rotate_pdf	rotate all or specific pages by 90/180/270°
remove_pages	delete specific pages
compress_pdf	shrink file size (lossless structural compression)
add_watermark	stamp diagonal Latin text on every page
add_page_numbers	number pages bottom-center
edit_metadata	read / set / clear title, author, subject, keywords
flatten_pdf	bake AcroForm field values into page content

Input conventions

Each PDF input accepts base64 (file content) or url (https, fetched server-side).
Limits: ≤10 MB per file, ≤200 pages. Non-PDF inputs are rejected.
Successful calls return a text summary plus the result PDF as base64 — decode and save it.

Not offered over MCP (honest boundaries)

Rendering-based conversions (PDF to images, grayscale, OCR) and AI translate/summarize/chat are browser-only, where files never leave your device.
compress_pdf does not downsample images; for stronger compression use the website’s target-size compressor.
edit_metadata clear mode resets standard info fields only; full XMP scrubbing is offered by the website’s metadata tool.
