Get current memory usage statistics
AI agents call memory_usage to retrieve information from Filopastry without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool queries and returns data about system memory usage with no side effects. It is purely informational and read-only. Severity is low because memory usage statistics pose minimal risk even if misused by an AI agent; they cannot cause data loss, code execution, or financial harm.
From the tool's definition Tool name is 'memory_usage' and description states 'Get current memory usage statistics' — this retrieves system information without modifying, deleting, or executing operations.
Attacks that exploit this kind of access
Get current memory usage statistics. It is categorised as a Read tool in the Filopastry MCP Server, which means it retrieves data without modifying state.
Register the Filopastry MCP server in PolicyLayer and add a rule for memory_usage: 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 Filopastry. Nothing to install.
memory_usage 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 memory_usage 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 memory_usage. 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.
memory_usage is provided by the Filopastry MCP server (youwenshao/filopastry). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
memory_usage is one line of Filopastry's registry record.
The record carries the whole server: verified identity, auth posture, risk grade, every tool classified, recommended policy — re-checked continuously.
