Connect Claude & ChatGPT to Blueink

Ask your AI to send a document for e-signature, check which envelopes are still waiting, or get the signed PDF from Blueink. It can create signature requests from a file or a template, save them as drafts, remind signers and fix a signer's email or phone. It also reads what signers filled in and the certificate of evidence for each signer.

Questions

What can the AI do in Blueink?

The AI can create signature requests from files or templates, send drafts, update or cancel requests, tag them, remind signers and fix signer details. It can search and read bundles, signers, templates, envelope templates and contacts, read field values, activity history, signed files and certificates of evidence, and save or update contacts.

Does the AI see my Blueink credentials?

No. Your Blueink API key and account details 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 search and tracking only. Sending a request is legally binding and billable, reminders email or text the signer, and cancelling cannot be undone. All of them can require your approval before they run. Every tool call is logged.

Does it work with ChatGPT?

Yes. In ChatGPT go to Settings › Apps & Connectors › Advanced and turn on Developer mode, then 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 Blueink account with an API plan or trial.

Can the AI prepare a request without sending it?

Yes. When it creates a request, it can save it as a draft instead of sending it. You can check the draft in Blueink, and the AI sends it later when you ask. Without the draft setting, Blueink sends the request to the signers at once.
