Perplexity

Automate physical gifting from your Claude Desktop chat

The `send_shipment` tool lets Claude Desktop dispatch physical greeting cards and customized gifts directly to your customers' doorsteps. When you tell your local desktop client to send a follow-up gift, this MCP server initiates the order through your MailboxPower account instantly, translating your chat prompt into a real-world delivery. You can check which campaigns are active by having the desktop agent run `list_automations`. If you want to trigger a multi-step mailing sequence for a new lead, the desktop app calls `add_contact_to_automation` to queue up the physical mailings without you opening a browser.

Sync CRM contacts using this MCP Server

The `create_contact` tool enables Claude Desktop to write new recipient details directly into your MailboxPower address book during your conversations. If you paste a raw email signature into your desktop chat window, the agent parses the physical address and runs this tool to build a clean contact record. To keep things organized, the desktop agent uses `add_contact_to_group` to segment your new contacts right away. It can also pull existing records using `get_contact` to verify shipping addresses before you authorize a package delivery.

Organize mailing groups locally inside Claude Desktop

The `create_group` tool lets Claude Desktop build targeted mailing lists for your seasonal gift campaigns. You tell the desktop client who should receive your holiday cards, and it creates the segment and populates it in one go. The desktop agent keeps track of your distribution lists by running `list_groups` to see what is already configured. It can also run `list_contacts` to filter recipients, ensuring you never double-ship a physical package to the same person.
