Get US states that start with a specific letter (case insensitive).
AI agents call get_states 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 state information based on a filter parameter (starting letter). It performs a simple lookup and returns data without creating, modifying, deleting, executing code, or committing financial obligations. The operation is read-only with minimal blast radius.
