AI agents call find_mp to retrieve information from GovUK 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 publicly available information about MPs without modifying, executing operations, or producing financial or destructive effects. It is a straightforward query/search function that returns data about elected officials based on provided search parameters. The low severity reflects the minimal risk from misuse—returning public information about MPs poses no security, privacy, or operational threat.
