List every SSH-capable machine this server knows about (but is NOT yet connected).
AI agents call get_available_connections 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.
This tool only queries and returns a list of available SSH connections without creating, modifying, executing commands on, or deleting any resources. However, severity is elevated to medium because the information disclosed (inventory of SSH-capable machines and their network accessibility) could inform a follow-up attack using sibling tools like execute_command or secure_execute_command, reducing the attacker's…
From the tool's definition Tool description states 'List every SSH-capable machine' — a retrieval operation with no side effects. The verb 'list' is a classic Read operation.

Attacks that exploit this kind of access
List every SSH-capable machine this server knows about (but is NOT yet connected). It is categorised as a Read tool in the SSH MCP Server MCP Server, which means it retrieves data without modifying state.
Register the SSH MCP Server MCP server in PolicyLayer and add a rule for get_available_connections: 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 SSH MCP Server. Nothing to install.
get_available_connections 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 get_available_connections 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 get_available_connections. 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.
get_available_connections is provided by the SSH MCP Server MCP server (vilasone455/ssh-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
