MCP server
Connect Claude, ChatGPT or another AI assistant to your readyink.ai account. Ask it which documents are waiting on a signature, find a signed copy, or prepare and send a document. It shows you the cost and asks before anything is sent.
https://mcp.readyink.ai/mcpConnect your assistant
- Copy the address above.
- Add it to your assistant:
- Claude: Settings › Connectors › Add custom connector. Works on the web, desktop and mobile.
- ChatGPT: Settings › Apps › Advanced settings, turn on developer mode, then Create app.
- Other assistants: anything that supports remote MCP servers. Look for "Add connector", "MCP server" or "Custom app".
- Sign in to readyink.ai when the assistant asks, choose what it may do, and choose Live or Test.
You can see, change and disconnect every connected assistant on the Integrations page in readyink.ai.
A Test connection uses the sandbox: sends cost 0 tokens, emails and texts go to your test inbox under Settings › Developers, and the text code is always 000000. Nothing reaches real people.
Try asking
- Which documents are still waiting on a signature?
- Who hasn't signed the 2027 Transfer of Ownership yet?
- Find the signed copy of the Acme Roofing NDA.
- Create a draft called Mutual NDA for Ana Diaz at ana@example.com, place the fields, and tell me what it costs to send.
What an assistant may do
When you connect, you choose permissions. Send for signature starts off; turn it on there or later on the Integrations page. Changes apply to the assistant's next request.
| Permission | Lets the assistant |
|---|---|
| See documents, signed copies and token balance | Always on. Read titles, recipients, statuses, signed copies, certificates and your balance. |
| Prepare drafts | Upload PDFs, add recipients and place fields. Nothing is sent. |
| Send for signature | Send, remind and cancel. Sends use tokens, 1 per signer. It asks you first. |
| Make links to buy tokens | Give you a link to buy tokens. It never buys them. |
Assistants can never sign for anyone, buy tokens or change your account settings.
How sending works
- The assistant prepares the draft and calls
quote_send, which shows the signers, the tokens it costs and your balance after. - It shows you the cost and asks you to confirm. Claude and ChatGPT also ask before any tool that sends, reminds or cancels.
- Only then does it call
send_documentwith that quote. If a signer was added or removed since, the send is refused and it quotes again.
Owners and admins can turn assistant sending off, and set a daily token limit for all assistants (25 by default), on the Integrations page.

Privacy and security
- Sign-in: OAuth 2.1 with PKCE. Assistants never see your password. Access tokens last an hour, and disconnecting stops them straight away.
- What we keep: for each request, which tool was used, which document it concerned, and when, so you can see recent activity. We keep these for 90 days. We don't receive or store your conversation with the assistant.
- Your account only: an assistant sees the same documents you can see in readyink.ai, in one workspace.
- Activity history: anything an assistant does to a document, like sending it, is recorded in its history and certificate as done through that assistant.
