AI agents call lichess_get_puzzle to retrieve information from Lichess MCP without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool purely retrieves and queries existing puzzle data from Lichess without creating, modifying, executing operations, or deleting anything. It has no capability to affect game state or user data beyond passive information retrieval. The blast radius of misuse is negligible—an agent could only spam requests or retrieve puzzles, neither of which causes harm.
From the tool's definition Tool retrieves a specific chess puzzle by ID and returns static puzzle data (board position, moves, theme, difficulty rating). The description uses "Get" and "Returns" indicating a query operation with no side effects or state changes.
