PaperOffice MCP Server

Give your AI assistant access to your documents — in plain language, in under 60 seconds.

Search, read, OCR, classify, extract, sign and analyse documents straight from Claude, Claude Cowork, Cursor, ChatGPT, Grok or Windsurf. No SDK, no boilerplate, no local install.

Why this matters

Your documents live in a DMS. Your AI assistant lives in your IDE or chat window. PaperOffice connects the two through the Model Context Protocol — so you can just ask, and the model does the work across every authorized workspace.

"List all unpaid invoices across my workspaces, with totals and overdue flags."
"OCR this scanned contract and extract the signing date and parties."
"Classify these 50 documents and file them by type."

No prompt engineering, no API code — the model picks the right PaperOffice tool and runs it.

60-second setup

1 · Auth

You need a PaperOffice account — the free plan is enough to try everything here. No account yet? Create one at app.paperoffice.ai/en/register/ (no credit card).

Claude, ChatGPT and Grok start with OAuth 2.1: the client opens the PaperOffice sign-in, you approve, no token in any file. For Cursor, DMS, or as an alternative: sign in at app.paperoffice.ai, open Account → API and create a User token (po_ut_) or a Group token (po_gt_, limited to the workspaces of one group). po_sk_ and po_pk_ are blocked for MCP.

2 · Paste one URL into your client

Claude Desktop / Anthropic Directory (OAuth 2.1, no key in file) — configs/claude_desktop_config.json

{
  "mcpServers": {
    "paperoffice": {
      "url": "https://mcp.paperoffice.ai/claude"
    }
  }
}

/dms, /cursor and /grok share the Documents Operations catalog (including TTS). /claude is Directory without TTS. /chatgpt (alias /openai) is the ChatGPT connector (Directory without TTS, OTP/unlock).

Full headless DMS (po_ut_ / po_gt_) — configs/dms_mcp.json → /dms. Same catalog as /cursor and /grok.

ChatGPT / Grok (OAuth 2.1, no key in file) — /chatgpt (alias /openai) or /grok (configs/openai_mcp.json, configs/grok_mcp.json). po_ut_ / po_gt_ remains an alternative for /chatgpt.

Everything (300+ MCP tools across every module) — configs/mcp_full.json → /mcp-full.

3 · Ask away

That's it — your AI now works with your documents.

Choose your scope — you decide, not your client

Any client can use any URL. The paths below are convenience profiles, not limits: go full from day one, or pick Directory / ChatGPT policy surfaces when a catalog requires it.

Client shortcuts: https://mcp.paperoffice.ai/cursor = same Documents Operations catalog as /dms · https://mcp.paperoffice.ai/grok = same Documents Operations catalog as /dms · https://mcp.paperoffice.ai/claude = Directory without TTS · https://mcp.paperoffice.ai/chatgpt = ChatGPT connector (alias https://mcp.paperoffice.ai/openai) · https://mcp.paperoffice.ai/mcp = slim IDE subset.

Why scopes at all? Fewer tools = faster, more accurate tool-selection by the model, and some clients enforce a tool-count cap. /mcp is the slim IDE subset. None of this limits what PaperOffice can do — switch to /mcp-full anytime for media, CRM and telephony.

Ready-made config files for every profile are in configs/.

Per-client quick reference

These are starting points — change the URL whenever your task needs a different scope.

Marketplace plugins

Prefer a one-click install? The same server is packaged as a plugin for two marketplaces:

ChatGPT and Claude do not need a repository: connect the /chatgpt or /claude URL directly, or install PaperOffice from their app directories once listed.

Official MCP Registry

PaperOffice is published in the official MCP Registry as io.github.paperoffice-ai/paperoffice-mcp — the manifest is server.json in this repository. Clients and directories that read the registry (VS Code, Glama, PulseMCP and others) find the six lanes there without any manual entry.

# Claude Code
claude mcp add --transport http paperoffice https://mcp.paperoffice.ai/dms

Agent Skills

The MCP server supplies the tools; paperoffice-ai/paperoffice-skills supplies the procedures — five SKILL.md files (API integration, invoice extraction, OCR, documents, tool discovery) that load as a Claude Code plugin, a claude.ai skill upload, or inside the Cursor plugin.

What you can do

Why PaperOffice

• EU-sovereign — own Tier III data centres in Spain & Germany. GDPR-aligned, no mandatory US cloud.

• Zero-shot IDP — extraction without template training, powered by specialized LLMs.

• Pay-per-use — transparent credits, no per-seat lock-in.

• API-first — 300+ API/MCP-Tools via REST or MCP. MCP uses OAuth 2.1 or a User token (po_ut_ / po_gt_) — see Postman.

• 24+ years — document management since 2002.

Prefer plain REST?

Paste this into any AI assistant for the full API — it reads the docs and writes the code:

Machine-readable context: paperoffice.ai/llms.txt · api.paperoffice.ai/latest/docs/llms.txt

Technical notes

• Transport: Streamable HTTP (remote MCP) — no stdio, no local process

• Base host: mcp.paperoffice.ai

• Auth: OAuth 2.1 first for Claude / ChatGPT / Grok (no token in the file). Bearer (po_ut_ / po_gt_) for Cursor, DMS, and as an alternative. po_sk_ and po_pk_ are blocked for MCP.

• Public claim: 300+ API/MCP-Tools (unified REST + MCP). Do not cite 250/260/350/357/500 or drifting profile integers.

• Claude.ai network allowlist: mcp.paperoffice.ai and api.paperoffice.ai (two fs — never paperofice)
