The address
For assistants that use MCP:
https://paperagent.dev/mcpWhere it goes
Settings → Connectors → Advanced → Developer mode
- Open ChatGPT in a browser and go to Settings → Connectors → Advanced.
- Switch on Developer mode.
- Back in Connectors, choose Create, and paste the address above as the MCP server URL.
- ChatGPT signs you in by email the first time it calls a tool that needs an account. get_pricing and validate_address answer before that.
The listed app
PaperAgent is also built as a ChatGPT app — the letter preview, the status timeline and the payment sheet, in the chat rather than in a settings screen. It is running and waiting on review by OpenAI. When it is listed, this is where the link will be, and none of the above will be necessary.
The MCP tools, pricing and mailing restrictions are on the docs page.
