Search for a team member by ID or email (team owners/admins only).
AI agents call search_team_member to retrieve information from CustomGPT MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves or queries team member information without side effects. It performs a lookup operation that returns existing data. The severity is low because: (1) it only reads data, (2) blast radius is limited to team member metadata visibility, and (3) access is restricted to authorized roles. No data is created, modified, deleted, or financial actions are taken.
From the tool's definition Tool name is 'search_team_member' with description stating it 'Search[es] for a team member by ID or email'. The verb 'search' and lack of any modification, deletion, or execution language indicate a read-only retrieval operation.
