Pbx MCP Overview

The pbx-mcp MCP server connects AI assistants to Asterisk through AMI and FreeSWITCH through ESL. It exposes tools for inspecting switch health, channels, endpoints, registrations, SIP profiles, dialplans, and command output, with optional call origination and hangup actions. Read-only operation is the default, while write tools appear only when explicitly enabled. Use it when an agent needs live PBX diagnostics or controlled call management rather than static configuration advice.

Primary Use Cases for Pbx MCP:
  • Inspect active calls and channel state
  • Check offline Asterisk endpoints
  • Diagnose FreeSWITCH gateway registration
  • Review an Asterisk dialplan context
