Run real-time campaign checks inside your Claude Desktop chat.

The `list_campaigns` tool lets Claude Desktop pull active outreach sequences straight into your chat panel. Your agent reads live metrics via `get_campaign_stats` to pinpoint exactly which sequences are performing and which ones are stalling out. You don't need to log into the web dashboard to see what's happening. Just ask Claude Desktop to check campaign performance, and the MCP server returns hard numbers instantly.

Control prospect status without leaving Claude Desktop.

The `pause_person` and `resume_person` tools give your Claude Desktop agent direct control over individual prospect schedules. If a prospect replies with a negative sentiment, you can tell Claude Desktop to pause them immediately before the next automated email fires. This local execution keeps your domain reputation safe. Claude Desktop processes the status change locally through your config file, letting you handle outreach triage during active chat sessions.

Add new leads to sequences through Claude Desktop.

The `add_person` tool lets you inject new prospect records directly into active Reply.io campaigns from your Claude Desktop interface. When you feed Claude Desktop a list of raw contacts, it validates the data and pushes them into the sequence. You can also run `list_email_accounts` to verify which sender profile has the bandwidth to handle the new volume. This prevents sender fatigue and keeps your daily outbound volume balanced.
