What ssh_list_servers does on SSH MCP Server

AI agents call ssh_list_servers to retrieve information from SSH MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

Why ssh_list_servers needs a policy

This tool only retrieves and displays existing configuration data (list of server names, count, and status). It performs no write, delete, execute, or financial operations. The impact is limited to information disclosure about which servers are configured, which is a read-only operation with minimal risk in an SSH management context.

From the tool's definition Tool name 'ssh_list_servers' and description 'List all configured SSH servers from the configuration file' indicates a query operation that retrieves and returns a list of server names and configuration metadata without modification.
