Handwrytten MCP Server

What it does

Handwrytten MCP Server lets AI assistants send real, pen-written notes on physical cards through the Handwrytten service. Robots with real pens write your message on premium stationery and mail it to any address. The app renders interactive UI panels inside Claude Desktop and VS Code Copilot — live card previews, handwriting animations, and basket summaries — so you can see exactly what will be sent before confirming.

Key features

• Card preview panel — Interactive HTML preview of selected card designs with handwriting style visualization before sending
• Writing animation — Live Lottie-based animation showing how your message will appear in the chosen handwriting font
• Basket summary — Review all pending orders in a single interactive panel before checkout
• Full order lifecycle — Send single or bulk handwritten notes, track orders, and check delivery status
• Custom card designer — Upload logos and images, create custom card designs with QR codes and gift card attachments
• Address book management — Create, update, and delete recipient and sender addresses; supports international shipping
• Remote OAuth support — Connect directly via https://mcp.handwrytten.com/mcp with zero local setup
