Connect Papero to Claude or ChatGPT

The Papero connector lets Claude or ChatGPT use Papero from the chat. Once you add it, the assistant can search scholarly papers, look up and format references, and read your Papero documents.

The connector is read-only. It cannot change or delete anything in Papero, and it does not run Papero's AI features. It works on Free and Plus.

The connector address

Every assistant needs the same address:

https://app.papero.ai/mcp

To copy it from Papero, open Settings > Integrations. On the Claude and ChatGPT card, press Copy.

Add it to Claude

1. In claude.ai or Claude Desktop, open Settings, then Connectors, and choose Add custom connector.
2. Name it Papero, paste the address and add it.
3. Click Connect. A Papero page opens in your browser.
4. Sign in to Papero if you are asked, then press Allow.

On a Team or Enterprise plan, an owner adds the connector for the organisation first.

Add it to ChatGPT

1. Turn on developer mode in ChatGPT's settings.
2. Create an app named Papero, with the address above and OAuth as its authentication.
3. Sign in to Papero when ChatGPT asks, then press Allow.

Developer mode depends on your ChatGPT plan and, in a workspace, on what its admin allows.

Add it to Claude Code

Run this command:

claude mcp add --transport http papero https://app.papero.ai/mcp

Then type /mcp in Claude Code, choose papero and sign in.

Sign in and allow

You sign in on Papero's own page, so the assistant never receives your password or an API key. The page names the app that asks, as in "Connect Claude to Papero", and says what it will be able to do. Check the app's name and the address you will return to, then press Allow. Press Cancel to stop.

If you are not signed in, press Sign in to Papero. When you have signed in, press I have signed in, continue. If you are new to Papero, you can sign up first. On a phone, the link in the confirmation email opens outside the assistant, so start the connection again from the assistant once your email is confirmed.

Papero asks you every time an app connects, even one you connected before.

What the assistant can do

• Search papers: find scholarly works on a topic in OpenAlex, sorted by relevance, date or citations, with filters for year, times cited and preprints. Each search counts toward your paper search allowance, and toward the daily paper search limit every plan has. A pasted DOI does not.
• Look up a paper: give it a DOI, PMID, arXiv ID or ISBN and get the paper's details back, including whether it was retracted.
• Format references: turn identifiers into a reference list in APA, MLA, Chicago (author-date), Harvard, IEEE, Vancouver, AMA, Nature or ACS. Nothing is saved to Papero.
• List your documents: see your own Papero documents, most recently changed first. Archived documents are left out unless you ask for them.
• Read a document: read a document's text and its reference list, in the document's citation style. A very long document is cut short.
• Check your plan: see your plan and how much of each allowance you have left.

Things to ask:

• "Turn these three DOIs into an APA 7 reference list."
• "Read my Papero document on climate migration and list the sentences that make a claim without a citation."
• "How many paper searches do I have left in Papero?"

The assistant cannot write into your document. To use something it wrote, paste it into your document yourself.

See and revoke connected apps

Open Settings > Integrations. Under Connected apps, each app shows when it was connected and when it was last used.

1. Press Revoke next to the app.
2. Papero asks whether to disconnect it. Press Disconnect.

The app loses access to your Papero documents straight away, and its next request is refused. To use it again, connect it again.

Access also ends on its own after a while, even when you use the app. When that happens, connect the app again. Deleting your Papero account deletes every connection.

Your data

Papero sends nothing to the assistant on its own. The assistant receives only the answers to the tools it calls, which can include the text of a document you ask it to read. What the assistant's provider, such as Anthropic or OpenAI, does with them is covered by that provider's own terms and privacy policy.

Papero records each connection and each tool call: which app, which tool, whether it worked, and when. It does not record what the assistant asked or what the tool answered. These records are in your data download. The Privacy Policy has the details, and the connector page on papero.ai shows the setup.
