Connect Claude & ChatGPT to MailMergic
Ask your AI to produce a contract, letter or certificate from one of your MailMergic templates. It reads the template's placeholders, fills them with the values you give it and starts the merge. It can then check the job status, fetch the generated document and cancel a merge that is still running.
Free plan, no credit card. Takes about a minute.
Try asking
“Which fields does template 4812 need?”
The AI reads the template and lists the placeholder fields it expects.
“Generate the service agreement for Nordic Foods ApS, signed by Anna Holm.”
It checks the template's placeholders, fills them with the details you gave and starts a merge that produces a Word or PDF document.
“Is the merge I just started finished?”
It reads the merge job and tells you its status, with the generated document when it is ready.
What your AI can do

Stay in control
Cancelling a merge can require your approval, and you choose which tools the AI can use.
“Show me the last merges for our offer letter template.”
It lists the merge jobs for that template with their status.
“Make one certificate each for these five course participants.”
It runs one merge per person on the certificate template, with each name and date filled in.
“Stop the merge I started by mistake.”
It cancels the merge job while it is still running.

Questions
What can the AI do in MailMergic?
The AI can read a template's placeholder fields, generate a merged Word or PDF document from a template, list the merges for a template, read one merge with its status and generated document, and cancel a merge that is still running.
Does the AI see my MailMergic credentials?
No. Your MailMergic 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 let the AI read templates and merges without generating documents. Cancelling a merge can require your approval before it runs. 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 MailMergic account.
Which MailMergic plan do I need?
