Lists all active SSH sessions with their details
AI agents call ssh_list_sessions to retrieve information from Mcp Ssh Tool without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves and displays information about active SSH sessions. It performs no modifications, deletions, code execution, or financial operations. While the broader SSH server enables potentially risky operations, this specific tool is purely informational and read-only, presenting minimal risk even if misused by an AI agent.
From the tool's definition Tool name 'ssh_list_sessions' and description 'Lists all active SSH sessions with their details' indicate a query/retrieval operation with no side effects.
Attacks that exploit this kind of access
Lists all active SSH sessions with their details. It is categorised as a Read tool in the Mcp Ssh Tool MCP Server, which means it retrieves data without modifying state.
Register the Mcp Ssh Tool MCP server in PolicyLayer and add a rule for ssh_list_sessions: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches Mcp Ssh Tool. Nothing to install.
ssh_list_sessions is a Read tool with low risk. Read-only tools are generally safe to allow by default.
Yes. Add a rate_limit block to the ssh_list_sessions rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.
Set action: deny in the PolicyLayer policy for ssh_list_sessions. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.
ssh_list_sessions is provided by the Mcp Ssh Tool MCP server (skot/mcp-ssh-tool). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
