Perplexity

Run Handwrytten in your CI pipeline

Use `send_card` as part of your deployment or notification scripts. Claude Code triggers the mailing the moment your build finishes or a bug is resolved. This integrates physical mail into your dev loop. It ensures your team gets a physical thank you note for major contributions.

Fetch Handwrytten data in the shell

Pipe the output of `list_categories` or `get_credit_balance` directly into other CLI tools. It allows you to build custom dashboards for your mail volume. You get real-time stats in your terminal. It turns the Handwrytten MCP Server into a source of truth for your physical outreach metrics.

Automate Handwrytten font selection

Use `list_fonts` to dynamically set the handwriting style for your cards. Claude Code selects the font based on the type of message it is sending. This keeps your mail consistent. It removes the need for manual configuration when you change your message templates.
