AI agents call get_memory to retrieve information from HomeLab Monitor without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
No description provided, but the naming pattern ('get_'), server context ('read-only'), and sibling tools (all non-destructive queries like get_gpu, get_host, get_containers) strongly indicate this retrieves memory data. This is a retrieval operation with no side effects, matching the Read category. Low severity due to limited blast radius of exposing memory statistics.
From the tool's definition Tool name 'get_memory' and sibling tools all prefixed with 'get_' or 'list_', consistent with read-only query operations. Server description explicitly states 'read-only MCP server'. Tool retrieves host memory metrics without modification capability.
Documented attack patterns abuse exactly the kind of access get_memory gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and HomeLab Monitor, and nothing reaches the server without passing your rules. This is the rule we recommend for get_memory:
{
"version": "1",
"default": "deny",
"tools": {
"get_memory": {}
}
}get_memory is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

get_memory. It is categorised as a Read tool in the HomeLab Monitor MCP Server, which means it retrieves data without modifying state.
Register the HomeLab Monitor MCP server in PolicyLayer and add a rule for get_memory: 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 HomeLab Monitor. Nothing to install.
get_memory 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 get_memory 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 get_memory. 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.
get_memory is provided by the HomeLab Monitor MCP server (sikamikanikobg/homelab-monitor). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
