List all configured Trello boards
AI agents call list_boards to retrieve information from Trello Knowledge MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool queries and returns information about available Trello boards without modifying, creating, deleting, or executing any operations. It has minimal blast radius—an AI agent misusing this tool could at most enumerate boards but cannot alter data or trigger external actions.
