Check health status of all connections, detect if any were closed by remote host
AI agents call ssh_check_connections to retrieve information from Ssh Mcp Server Secured without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool performs a read-only health check on existing SSH connections, retrieving status information about connection state. It does not execute commands, create/modify connections, delete connections, or perform financial operations. The severity is low because even if misused by an agent, checking connection health status poses minimal risk—it cannot alter system state, execute arbitrary code, or delete data.
From the tool's definition The tool 'check health status of all connections' and 'detect if any were closed' indicates a passive inspection operation that queries connection state without modifying, executing commands, or causing side effects.
Attacks that exploit this kind of access
Check health status of all connections, detect if any were closed by remote host. It is categorised as a Read tool in the Ssh Mcp Server Secured MCP Server, which means it retrieves data without modifying state.
Register the Ssh Mcp Server Secured MCP server in PolicyLayer and add a rule for ssh_check_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 Secured. Nothing to install.
ssh_check_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 ssh_check_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 ssh_check_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.
ssh_check_connections is provided by the Ssh Mcp Server Secured MCP server (marian-craciunescu/ssh-mcp-server-secured). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
