• src/agents_mcp_server/server.py:296-389 (handler)

  The complete handler function for the 'multi_tool_agent' MCP tool. It registers the tool via @mcp.tool decorator and implements the logic by constructing a multi-tool orchestrator agent that delegates to web search, file search, or computer action sub-agents based on enabled features and the user query.
