Connect Claude & ChatGPT to D4Sign

Ask your AI which contracts are still waiting for signatures, who has not signed yet, or to send a document out for signing in D4Sign. It can browse safes and folders, upload documents, add and remove signers, send and resend signing links, and download signed files. Signature follow-up gets done without opening each document.

Set up in three steps

1
Pick the app
Create a free HeyMyApps account and choose D4Sign from the app list.
2
Paste your key
Paste your D4Sign API key (tokenAPI). Log in to D4Sign and open the 'Dev API' menu to find it. This connection sends only the tokenAPI, so it works when the extra cryptKey is not enabled on your account.
3
Add the link to your AI
You get a personal MCP link. Add it to Claude, ChatGPT or Cursor:
1. Click your name, then Settings › Connectors › Add custom connector.
2. Paste your link as the Remote MCP server URL.
3. Switch it on from the + menu in a chat.

Questions

What can the AI do in D4Sign?

The AI can read safes, folders, documents, document status, signers, observers, users and your account balance. It can create folders, upload documents, add and remove signers, send documents for signature, resend signing links, add observers, download documents and cancel documents.

Does the AI see my D4Sign credentials?

No. Your D4Sign API key is encrypted at rest and never shown to the AI. After you save it, it is 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 status checks only. Sending for signature and resending links reach other people, and cancelling a document 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 go to Settings › Apps & Connectors › Advanced and turn on Developer mode, then add your HeyMyApps 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?

HeyMyApps has a free plan with no credit card required. Paid plans bill per completed task. You also need your own D4Sign account.

Does it work if my D4Sign account uses a cryptKey?

Not yet. D4Sign can ask for a second key, the cryptKey, when it is enabled on the account. This connection sends only the tokenAPI, so it works on accounts where cryptKey is not enabled. D4Sign's documentation also sets a default limit of 10 API requests per hour.
