   Hi @skunkwerk,

   I've submitted a PR that addresses this feature request: #728

   The PR adds enable() and disable() methods to tools, which allows temporarily disabling tools and re-enabling them when needed.

   Would this solution work for your use case?

   I can't speak for @skunkwerk, but for our use case (a multi-tenant MCP server), no, we need to actually remove the tool, not just disable it.

   Right now, we are doing some hackery like

       def _remove_tool_from_mcp(self, tool_name: str) -> bool:
           """Remove a tool from the MCP server.
   
           NOTE: There is no API available for tool removal, so we edit private members ourselves.
           """
           if tool_name in mcp._tool_manager._tools:  # noqa: SLF001
               del mcp._tool_manager._tools[tool_name]  # noqa: SLF001
               return True
           return False
