ExMCP.MessageProcessor.Dispatcher (ex_mcp v0.10.0)

View Source

Unified message dispatcher that eliminates duplication between different handler modes.

This module provides a single dispatch mechanism that can handle:

  • Direct handler calls (DSL servers)
  • GenServer-based handlers
  • Handler module calls

All business logic is delegated to the Handlers module, while this module handles routing and response adaptation based on the calling mode.
