Chat with your documents in your AI assistant

Paperarchive connects to AI assistants as an MCP connector. Once linked, you can ask things like "Find my phone contract", "How much was the electricity bill in March?", or "List my latest bank statements" - and your assistant looks it up in your archive for you. The connector works with any assistant that supports custom MCP connectors, including Claude, ChatGPT, and Grok.

What your assistant can do

  • Search your documents by content, sender, category, or tag.
  • Read document details like amounts, dates, and extracted text.
  • Look up transactions from processed bank statements.
  • Answer "What is open or due?" using the events Paperarchive extracts - invoices, contracts, and policies with state, amount, and due date.
  • Give you a short-lived download link for the original file.

The connection is read-only: a connected assistant can never create, change, or delete documents in your archive.

What you need

  • A Paperarchive Premium plan (or an active trial) - the same requirement as for API keys.
  • An assistant plan that supports custom connectors (all three assistants require a paid plan for this).

How connecting works

The flow is the same everywhere: add this URL as a custom connector in your assistant, and you will be sent to Paperarchive to approve the connection.

https://api.paperarchive.io/mcp
  1. Add the URL in your assistant (exact steps per assistant below).
  2. You are redirected to Paperarchive. Log in if needed.
  3. Review the permissions, choose which Spaces the assistant may access, and click Allow access.
  4. Back in your assistant, enable the connector in a chat and start asking questions.

You can also find the URL with a copy button in the app under Settings > API Keys > Connected Apps.

Claude

In Claude (claude.ai or the desktop app), open Settings > Connectors, click Add custom connector, and paste the URL. On Team/Enterprise plans an admin adds the connector in the organization settings.

ChatGPT

In ChatGPT on the web, enable Developer mode under Settings > Apps > Advanced settings (on some accounts the toggle is under Settings > Connectors > Advanced). Then add a new connector with the URL and complete the approval flow.

Grok

Open grok.com/connectors, click New Connector, choose Custom, and paste the URL.

Choosing Spaces

During approval you decide which Spaces the connection can see, for example only your business Space. Everything outside the selected Spaces stays invisible to the assistant - this is enforced on the server, not just in the interface.

Privacy

  • A connected assistant only receives what its tools request: search results, document details, and statement data from the Spaces you approved.
  • Document content that an assistant reads becomes part of your conversation with that assistant. Treat conversations with the same care as the documents themselves.
  • You stay in control: disconnecting stops all access immediately.

Disconnecting

Go to Settings > API Keys > Connected Apps in Paperarchive and click Disconnect next to the app. The assistant immediately loses access. You can reconnect at any time.

Troubleshooting

  • The assistant asks to re-authenticate: the login expired after longer inactivity. Just run the connect flow again.
  • The assistant cannot find a document: check that the document's Space was selected when you connected, and that processing has finished.
  • Upgrade notice during connect: the connector needs an active Premium or trial plan.

Developers find the technical details (OAuth, tools, Claude Code setup) in the API documentation.
