What performance_report does on Claude Flow
AI agents call performance_report to retrieve information from Claude Flow without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
Why performance_report is rated Low
The tool generates a performance report, which is a read/query operation that collects and presents timing and metrics data without modifying or deleting anything. The description is truncated ('Use when native shell timing ('), which slightly lowers confidence, but the core action is reporting/reading. Severity is low as misuse would at most expose performance data.
From the tool's definition 'Generate performance report' — reads and aggregates performance metrics/timing data into a report
Attacks that exploit this kind of access
The rule that runs performance_report safely
PolicyLayer is an MCP gateway: it sits between your AI agents and Claude Flow, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For performance_report, this is the rule to start with:
performance_report is read-only, so it stays allowed. Everything else on the server is denied unless you say otherwise.
The button opens the PolicyLayer dashboard: create your workspace, connect Claude Flow, apply this rule, and every performance_report call is checked against it from then on.
Questions about performance_report
Generate performance report Use when native shell timing (. It is categorised as a Read tool in the Claude Flow MCP Server, which means it retrieves data without modifying state.
Register the Claude Flow 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 Claude Flow. 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 Claude Flow MCP server (claude-flow). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
