AI agents call list_java_processes to retrieve information from Memory Shell Detector MCP without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
Listing Java processes is a read-only operation that gathers system information without modifying, deleting, or executing anything. While the server handles memory shell detection/removal (which includes destructive operations), this specific tool only enumerates processes, fitting the 'Read' category.
From the tool's definition Tool name 'list_java_processes' and server context indicate this retrieves information about running Java processes. No description provided, but the function name clearly denotes a query/listing operation with no side effects.
Documented attack patterns abuse exactly the kind of access list_java_processes gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Memory Shell Detector MCP, and nothing reaches the server without passing your rules. This is the rule we recommend for list_java_processes:
{
"version": "1",
"default": "deny",
"tools": {
"list_java_processes": {}
}
}list_java_processes is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

list_java_processes. It is categorised as a Read tool in the Memory Shell Detector MCP MCP Server, which means it retrieves data without modifying state.
Register the Memory Shell Detector MCP server in PolicyLayer and add a rule for list_java_processes: 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 Memory Shell Detector MCP. Nothing to install.
list_java_processes 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 list_java_processes 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 list_java_processes. 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.
list_java_processes is provided by the Memory Shell Detector MCP server (ruoji6/memory-shell-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from Memory Shell Detector MCP, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
