WHAT IT DOES

What ssh_list_sessions does on SSH MCP Server

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

RISK

Why ssh_list_sessions is rated Low

This tool performs a passive enumeration of active sessions and available resources. It has no side effects, does not execute code, does not modify state, and does not delete or move money. The blast radius of misuse is minimal—an agent could only learn about what sessions exist, which is informational. Classified as Read with low severity.

From the tool's definition Tool name 'ssh_list_sessions' and description 'List all active SSH sessions and remaining connection slots' indicate a read-only query operation that retrieves status information about existing sessions without modifying or executing anything.

RECOMMENDED RULE

The rule that runs ssh_list_sessions safely

PolicyLayer is an MCP gateway: it sits between your AI agents and SSH MCP Server, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For ssh_list_sessions, this is the rule to start with:

ssh_list_sessions Allowed

ssh_list_sessions is read-only, so it stays allowed. Everything else on the server is denied unless you say otherwise.

{
  "version": "1",
  "default": "deny",
  "tools": {
    "ssh_list_sessions": {}
  }
}

ALLOW ONLY THIS TOOL → Instant setup, no code required.

The button opens the PolicyLayer dashboard: create your workspace, connect SSH MCP Server, apply this rule, and every ssh_list_sessions call is checked against it from then on.
