Notes

Handwrytten runs an official hosted MCP server at mcp.handwrytten.com/mcp (source and setup in github.com/handwrytten/mcp-server, MIT licensed). Claude connects with OAuth using a Handwrytten login; ChatGPT uses mcp.handwrytten.com/chatgpt/mcp; gateways and custom agents can send a Handwrytten API key in an X-API-Key header instead. Tools send single or bulk handwritten notes, browse cards and handwriting styles, manage recipient and sender addresses, build custom cards with logos, QR codes, gift cards and inserts, and track orders. Sending a note mails a physical card, so treat it as a write action that needs a person's approval. Dealers use it for sold, service and lease-end follow-up.
