• src/mcp_panther/panther_mcp_core/tools/roles.py:17-105 (handler)

  The complete implementation of the 'list_roles' tool, including the @mcp_tool decorator for registration, input schema via Annotated Fields with Pydantic Field descriptions, and the full handler logic that queries the Panther REST API for roles, filters the response, and returns formatted results with pagination info.
