Connect Claude to PaperOffice (MCP)

Set up PaperOffice as an MCP connector in Claude — from the connector URL to authorizing with your user token. Afterwards, Claude answers questions directly from your documents.

What you will set up

  • Add PaperOffice as a custom connector in Claude
  • Authorize MCP access securely with your user token
  • Set tool permissions for the full feature set

Prerequisites

  • Claude account (web or desktop) with connector support
  • PaperOffice account with a user token (po_ut_ / po_gt_) from the API section

With the PaperOffice MCP server, Claude becomes an assistant for your document archive: search documents, summarize content, query workspaces — all in chat. The connection takes only a few minutes.

Get your user token ready

In PaperOffice, open PaperOffice Account → API and copy your user token (starts with po_ut_ or po_gt_). You will paste this token during authorization. Secret keys (po_sk_) are blocked for MCP and will not work.

Open “Customize” in the Claude sidebar

In Claude, select Customize at the bottom left of the sidebar.

Open Connectors and add a connector

Under “Customize”, choose Connectors, click + at the top right, and select Add custom connector.

Fill in the connector dialog

Enter the name and MCP URL — leave “Advanced settings” closed; no OAuth client ID is needed. Then click Add.

Name:               PaperOffice AI
Remote MCP server:  https://mcp.paperoffice.ai/claude

Authorize on the PaperOffice page

Claude opens a window on mcp.paperoffice.ai. Paste your user token (po_ut_ / po_gt_) there and click Authorize — not in Claude’s OAuth fields.

Review tool permissions

Back in Claude, review the tool permissions of the new connector. For the full feature set, choose Always allow for all tool groups.

Chat with Claude

PaperOffice is connected. Ask Claude, for example:

Show me the last five invoices from my workspace and summarize the amounts.
