Get performance metrics and statistics.
AI agents call ruvector_metrics to retrieve information from Claude Flow without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves performance metrics and statistics—a read-only operation with no side effects, no code execution, and no data modification. The verb 'Get' confirms data retrieval. While it operates in an AI orchestration context with swarms and neural networks, the tool itself only observes and reports performance data, making it a Read operation with low severity and low blast radius if misused.
From the tool's definition Tool name 'ruvector_metrics' and description 'Get performance metrics and statistics' indicate retrieval of observability data with no modification or execution.
Attacks that exploit this kind of access
Get performance metrics and statistics. 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 ruvector_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 Claude Flow. Nothing to install.
ruvector_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 ruvector_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 ruvector_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.
ruvector_metrics 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.
