Trigger calls and view logs in Claude Desktop

Stop switching between your browser tabs just to check who called your business. With this MCP server running in your Claude Desktop app, your agent scans your call history using `list_calls` to pull up-to-the-minute logs without lag. If you need to dial out, the agent triggers `make_call` directly inside your chat interface. It handles the connection instantly, letting you run your communications from a single sidebar.

Keep your contacts updated automatically

Managing clients shouldn't require manual database entries. When you receive a message or query, tell Claude Desktop to run `create_contact` to save the new lead details to your MightyCall account on the spot. You can also query your entire directory using `list_contacts`. This MCP integration retrieves names, phone numbers, and notes, giving your agent the exact context it needs to draft personalized follow-ups.

Never miss a voicemail lead again

Voicemails often sit unread in crowded inboxes. This integration lets Claude Desktop fetch audio transcripts and audio details via `list_voicemails` so you can read what your clients need. You can pair this with `list_business_numbers` to see which of your virtual phone lines is getting the most off-hours traffic. It gives you a clear picture of your inbound communication channels without opening a single dashboard.
