• magg/server/manager.py:508-535 (handler)

  The primary handler function for the 'magg_load_kit' MCP tool. Accepts a kit name, loads the kit configuration using KitManager, saves the config, and mounts any new enabled servers.

  Registers the 'magg_load_kit' tool (and other kit tools) by including self.load_kit in the tools list and applying the MCP tool decorator via self.mcp.tool.
