Connect Claude & ChatGPT to Writify
Ask your AI to send a handwritten card through one of your Writify campaigns. It looks up your active campaigns, then adds one or more cards with the recipient's name, address, country and your personal text. Writify writes and posts each card, and every card uses your Writify credits.
Free plan, no credit card. Takes about a minute.
Try asking
“Which Writify campaigns do I have running?”
The AI lists your active card campaigns with their IDs.
“Send a thank-you card to Anna Berg, Storgatan 12, 11455 Stockholm, Sweden, in the Thank you campaign.”
It finds the campaign ID and adds one card with Anna's name, address and country for Writify to write and post.
“Here are five new customers from this week. Send each of them a welcome card.”
It adds five cards to the welcome campaign in one call, one per recipient.
What your AI can do

Send handwritten cards
Add one or more cards to a campaign with recipient name, address, country and up to five personal text variables.
You stay in control
Sending uses your Writify credits, so you can require your approval before any cards go out.
“Send a card to Peter Holm and put 'see you at the fair in May' in the personal line.”
It adds the card and fills your text into one of the Variable1 to Variable5 fields your campaign uses.
“Before sending, show me the cards you are about to add.”
It lists each recipient, address and variable text so you can check them before the send goes through.
“Which campaign ID should I use for birthday cards?”
It lists your campaigns so you can pick the right one by name.

Questions
What can the AI do in Writify?
The AI can list your active card campaigns and add handwritten cards to a campaign, with the recipient's name, address, country and up to five personal text variables. Writify then writes and posts the cards.
Does the AI see my Writify API key?
No. Your Writify 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 only the campaign list. Sending cards uses your credits and results in real post, so it 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 Writify account, and each card you send uses your Writify credits.
How do I get a Writify API key?
Writify gives out API keys on request. Email [email protected] with your company name and the email address you want to register, and they send you a key. You paste it into PipMCP once.
