AI agents call deleteConnection to permanently remove resources in Mcp Ssh — typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.
This tool permanently removes a stored SSH connection configuration, which cannot be automatically recovered. While not as critical as deleting live system data, it is irreversible and causes loss of saved connection state. The high severity reflects that an AI agent inadvertently deleting connection configurations could disrupt workflows and require manual reconfiguration.
From the tool's definition Tool name 'deleteConnection' and description 'Deletes a saved SSH connection' explicitly indicate irreversible deletion of configuration data.
Documented attack patterns abuse exactly the kind of access deleteConnection gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Mcp Ssh, and nothing reaches the server without passing your rules. This is the rule we recommend for deleteConnection:
{
"version": "1",
"default": "deny",
"hide": [
"deleteConnection"
]
}deleteConnection disappears from the agent's tool list entirely, and any attempt to call it is denied. The rest of the server keeps working.

Deletes a saved SSH connection. It is categorised as a Destructive tool in the Mcp Ssh MCP Server, which means it can permanently delete or destroy data. Block by default and require explicit approval.
Register the Mcp Ssh MCP server in PolicyLayer and add a rule for deleteConnection: 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. Nothing to install.
deleteConnection is a Destructive tool with critical risk. Critical-risk tools should be blocked by default and only enabled with explicit human approval.
Yes. Add a rate_limit block to the deleteConnection 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 deleteConnection. 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.
deleteConnection is provided by the Mcp Ssh MCP server (shuakami/mcp-ssh). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
