get_competition_by_id
AI agents call get_competition_by_id to retrieve information from Unofficial WCA 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 competition information by ID from the WCA database. It performs a simple lookup with no side effects, data modification, or external operations. The blast radius of misuse is minimal since WCA competition data is public and read-only access poses no security risk.
