Your outreach data,
inside your AI tools.
MailQueue exposes a full MCP server with 34 tools. Connect it to Claude, Cursor, or any MCP-compatible agent and work with your contacts, sequences, inbox, and tasks through natural language.
What you can do with it
AI-assisted prospecting
Ask Claude to find contacts who opened but never replied, then enroll them in a follow-up sequence. No manual CSV exports, no switching tabs.
"Find contacts in workspace 1 who opened my Q3 sequence but didn't reply, and enroll them in the follow-up sequence."Automated reporting
Pull sequence analytics, reply categories, and task completion rates into a single conversation. Get a summary without building a dashboard.
"Show me open rates and reply rates for all active sequences in workspace 1, sorted by reply rate."Bulk operations via natural language
Create contacts, update task statuses, or enroll lists into sequences by describing what you want. The MCP server handles the API calls.
"Mark all overdue tasks in workspace 1 as skipped and create a new task to review them next Monday."Build on top of MailQueue
Use the MCP server as a backend for custom AI agents. Any tool that supports MCP can read and write your outreach data with full OAuth 2.1 authentication.
