Connect Claude & ChatGPT to Addo Sign

Ask your AI to send a contract for signing, check who is still missing a signature, or remind a recipient. It works from your Addo Sign signing templates, which hold the documents, and can follow every signing through its flow, recipients, files and rejections. You can also correct a recipient's details or cancel a signing.

Try asking

“Send our NDA template to Mette Hansen, [email protected], for MitID signing.”
The AI finds the template in your group and starts a signing with Mette as recipient. Addo Sign emails her the signing link.
“Which signings did we start this week?”
It lists signings created in the date range with their status and reference numbers.
“Who has not signed the lease agreement yet?”
It reads the recipients of the signing and shows who has signed and who is still missing.

Questions

What can the AI do in Addo Sign?

It can list groups, users and signing templates, start a signing from a template, and read signings, flows, recipients, files and rejections. It can update a signing or recipient, resend messages, and cancel or reactivate a signing. Uploading a new PDF is not supported, so documents come from your templates.

Does the AI see my Addo Sign access token?

No. Your Addo Sign credentials are encrypted at rest and never shown to the AI. After you save them, they are not shown again, not even to you. The AI only sees the results of the tools it calls.

Can I control what the AI is allowed to do?

Yes. You choose which tools are switched on, so you can start with read-only tracking. Starting a signing and resending messages contact your recipients, and cancelling cannot be undone, so these can require your approval before they run. Every tool call is logged.

Does it work with ChatGPT?

Yes. In ChatGPT, open Settings › Apps & Connectors › Advanced, turn on Developer mode and add your PipMCP link. Developer mode needs a paid ChatGPT plan: Plus, Pro, Business or Enterprise. The same link also works in Claude (Settings › Connectors › Add custom connector), Cursor and other MCP clients.

What does it cost?

PipMCP has a free plan with no credit card required. Paid plans bill per completed task. You also need your own Addo Sign account. PipMCP is an independent service and is not affiliated with Addo Sign.

Which signing methods can recipients use?

The methods enabled on your Addo Sign account, such as MitID, BankID or touch signature. The AI can list them and set the method per recipient when it starts a signing.
