Get all WCA countries.
AI agents call get_wca_countries 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 public WCA reference data (countries). It performs a simple read operation with no capability to modify, delete, or execute operations. The blast radius of misuse is minimal—an AI agent could only retrieve already-public country information. This is consistent with other read-only tools on the server like 'get_person_by_wca_id' and 'search_competitions'.
From the tool's definition Tool named 'get_wca_countries' with description 'Get all WCA countries' indicates a query/retrieval operation that returns a static list of country data with no modifications, deletions, or external side effects.
