Implementation Reference
- server_monitor/main.py:67-70 (handler)Registration and execution handler for the '_list_available_tools' MCP tool. This is a wrapper function decorated with @mcp.tool() that calls the helper list_available_tools(mcp) since the helper requires the MCP instance.
# 特殊处理list_available_tools，因为它需要mcp实例 @mcp.tool() def _list_available_tools(): return list_available_tools(mcp) - server_monitor/tools/utils.py:6-141 (helper)Helper function list_available_tools that implements the core logic for listing available tools by introspecting MCP tools or falling back to a hardcoded list of tool descriptions including schemas.
