AI agents call mcp_file_get_info to retrieve information from ShowDoc MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This is a read-only operation that queries and returns information about files or directories. It has no side effects, does not modify data, execute code, or delete anything. The blast radius of misuse is minimal — an AI agent could only learn about file/directory structure on the host system.
