Get all members of a board
AI agents call get_board_members to retrieve information from Trello MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

The operation is read-only and has minimal security impact; the worst case is information disclosure about board members, which is typically low-severity. Confidence is high because the name and description are explicit and unambiguous.
