AI agents invoke download_detector_tools to trigger actions in Memory Shell Detector MCP. What it does depends on the arguments the agent supplies, and its effects often reach beyond the immediate call — builds kicked off, notifications sent, workflows started.
The tool name implies downloading software/tools to a system, which is an external operation with potential side effects (fetching and installing executables). Given the server context (memory shell detection, SSH remote execution, execute_command sibling), downloading tools could introduce executables onto local or remote systems.
From the tool's definition Tool name 'download_detector_tools' on a server that includes 'execute_command' and 'remove_memory_shell' siblings; description is empty and uninformative.
Documented attack patterns abuse exactly the kind of access download_detector_tools 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 download_detector_tools:
{
"version": "1",
"default": "deny",
"tools": {
"download_detector_tools": {
"limits": [
{
"counter": "download_detector_tools_rate",
"window": "minute",
"max": 10,
"scope": "grant"
}
]
}
}
}download_detector_tools stays usable, but rate-capped — a runaway agent can't fire it dozens of times a minute. Everything else on the server is denied unless you say otherwise.

download_detector_tools. It is categorised as a Execute tool in the Memory Shell Detector MCP MCP Server, which means it can trigger actions or run processes. Use rate limits and argument validation.
Register the Memory Shell Detector MCP server in PolicyLayer and add a rule for download_detector_tools: 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.
download_detector_tools is a Execute tool with high risk. Execute tools should be rate-limited and have argument validation enabled.
Yes. Add a rate_limit block to the download_detector_tools 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 download_detector_tools. 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.
download_detector_tools 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.
