Get proxy server performance metrics
AI agents call proxy_get_performance_metrics to retrieve information from Web Proxy MCP Server 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 performance metrics from the proxy server. It is a read-only operation that retrieves system telemetry data without creating, modifying, deleting, or executing any actions. The blast radius of misuse is minimal; an attacker could gather information about proxy performance but cannot alter configuration, delete logs, or trigger external operations.
From the tool's definition Tool name contains 'get' and description states 'Get proxy server performance metrics' — retrieves performance data with no modification or side effects.

Register the Web Proxy MCP Server MCP server in PolicyLayer and add a rule for proxy_get_performance_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 Web Proxy MCP Server. Nothing to install.
proxy_get_performance_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 proxy_get_performance_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 proxy_get_performance_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.
proxy_get_performance_metrics is provided by the Web Proxy MCP Server MCP server (mako10k/mcp-web-proxy). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
