list_candidate_list_items
AI agents call list_candidate_list_items to retrieve information from CATS MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
The tool name strongly suggests enumeration or retrieval of candidate list items, consistent with the Read category. The 'list' pattern is a standard query operation in API design. Empty description lowers confidence slightly, but the naming convention and position among sibling tools (many of which are attachment/authorization/status operations) reinforces that this is a read operation.
From the tool's definition Tool name 'list_candidate_list_items' contains 'list' verb, which is a query operation that retrieves data without side effects. The absence of modify, delete, create, or execute keywords indicates read-only functionality.
