MCP-native escalation for AI agents

When your agent needs a human,
we make the call.

redphonr gives AI agents a direct line to you — via phone, SMS, Slack, or email. Configure escalation flows once and get contacted exactly when it matters.

Three steps to reach you

From zero to your agent having a direct line to you in under 5 minutes.

Step 1

Configure your flow

Define who gets contacted and how — email first, SMS after 5 min, voice call after 10. Set it once.

Step 2

Add the MCP tool

Add redphonr's MCP server to your agent. It gets an alert_human() tool with full escalation support.

Step 3

Get the call

When the agent triggers the tool, your escalation chain fires. Acknowledge from any channel.
