Get countries that start with a specific letter (case insensitive).
AI agents call get_countries to retrieve information from Country 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 information about countries based on a filter criterion (starting letter). It has no side effects, does not modify any data, and does not execute arbitrary code or external operations. This is a straightforward read operation with minimal risk.
