Get performance metrics and bottlenecks
AI agents call performance_report 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.
The tool fetches performance metrics and bottleneck information, which is a read-only operation. It does not modify, execute, or delete anything. Misuse potential is minimal as it only returns observational data about system performance.
From the tool's definition 'Get performance metrics and bottlenecks' — purely retrieves/queries diagnostic data with no side effects
Attacks that exploit this kind of access
Get performance metrics and bottlenecks. 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 performance_report: 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.
performance_report 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 performance_report 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 performance_report. 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.
performance_report 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.
