AI agents call listBackgroundTasks to retrieve information from Mcp Ssh without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves or queries the state of background tasks with no side effects. It falls squarely into the Read category. Severity is low because information about running tasks poses minimal risk—it does not execute commands, delete data, or modify system state. The confidence is high because the intent is unambiguous from both the name and description.
From the tool's definition Tool name 'listBackgroundTasks' and description 'Lists all background tasks currently running' indicate a read-only operation that retrieves information about running tasks without modifying, deleting, or executing anything.
Documented attack patterns abuse exactly the kind of access listBackgroundTasks 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 listBackgroundTasks:
{
"version": "1",
"default": "deny",
"tools": {
"listBackgroundTasks": {}
}
}listBackgroundTasks is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Lists all background tasks currently running. It is categorised as a Read tool in the Mcp Ssh MCP Server, which means it retrieves data without modifying state.
Register the Mcp Ssh MCP server in PolicyLayer and add a rule for listBackgroundTasks: 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.
listBackgroundTasks 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 listBackgroundTasks 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 listBackgroundTasks. 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.
listBackgroundTasks 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.
