Retrieve system performance metrics including RAM usage, CPU usage, active sessions, event loop latency, and garbage collection stats.
AI agents call get_system_metrics to retrieve information from Monti APM MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This is a pure data retrieval operation that queries existing APM metrics without side effects. No data is created, modified, deleted, or executed. The blast radius of misuse is minimal—an agent could only gain visibility into system performance characteristics, which is informational rather than harmful.
From the tool's definition Tool description states 'Retrieve system performance metrics' with no modification, deletion, or execution capabilities. Returns observational data only: RAM usage, CPU usage, active sessions, event loop latency, and garbage collection stats.
Attacks that exploit this kind of access
Retrieve system performance metrics including RAM usage, CPU usage, active sessions, event loop latency, and garbage collection stats. It is categorised as a Read tool in the Monti APM MCP Server MCP Server, which means it retrieves data without modifying state.
Register the Monti APM MCP Server MCP server in PolicyLayer and add a rule for get_system_metrics: 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 Monti APM MCP Server. Nothing to install.
get_system_metrics 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_system_metrics 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_system_metrics. 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_system_metrics is provided by the Monti APM MCP Server MCP server (quavedev/montiapm-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
