Before you start
- You need a PaperOffice account with at least one workspace and credits.
- Your Claude plan must allow connectors (Pro, Max, Team or Enterprise; Team/Enterprise admins may need to enable the connector for the organisation first).
- Connector URL:
https://mcp.paperoffice.ai/claude
Option A — from the Connectors Directory
- In claude.ai open Settings → Connectors.
- Find PaperOffice in the directory and choose Connect.
- A PaperOffice sign-in window opens. Sign in with your PaperOffice account.
- Review the requested access and confirm.
- Back in Claude, enable the PaperOffice tools for the conversation (tools icon in the chat input).
Option B — as a custom connector
- Settings → Connectors → Add custom connector.
- Name:
PaperOffice, URL:https://mcp.paperoffice.ai/claude. Leave client ID and secret empty — OAuth 2.1 starts automatically. - Choose Add, then Connect and sign in as above.
Claude Desktop and Claude Code
Claude Desktop uses the same connector list as claude.ai — connect once, it is available everywhere you are signed in.
Claude Code (terminal):
claude mcp add --transport http paperoffice https://mcp.paperoffice.ai/claude
Then run /mcp inside Claude Code to complete the OAuth sign-in.
First test
Ask Claude: "Which PaperOffice workspaces can I access?" — it should list your workspaces. Then try "Find the latest invoice from Muster GmbH and summarise it."
Notes
- One connection per Claude account and PaperOffice user. Team members connect individually with their own PaperOffice login.
- Access can be removed at any time — see Disconnect Claude and revoke access.
- Something not working? See Troubleshooting Claude.
