Team-wide mail automation with VS Code Copilot

This MCP Server lets your development team build physical mail pipelines without leaving their workspace. By sharing the config, every engineer using VS Code Copilot can run `create_letter` and `create_postcard` to test templates. The agent helps your team write reliable handlers for physical mailings. It eliminates the need for individual developers to manage separate API sandboxes or manually curl endpoints.

Live address validation in your shared workspace

Keep your user database accurate from the moment of ingestion. VS Code Copilot runs this MCP Server to debug address form issues during active development. When building search interfaces, the agent uses `autocomplete_address` to inspect the suggested payloads. This ensures your front-end components match the exact structure the mail API expects.

Verify check issuance and track deliveries

Prevent payment errors by testing check workflows in your IDE. VS Code Copilot calls `create_check` to verify your financial automation routing and metadata formatting. Your team can also debug delivery webhooks easily. The agent uses `get_mail_tracking` to pull live transit statuses, making it simple to verify that your app processes delivery notifications correctly.
