What performance.measure_response_latency does on ContextForge MCP Gateway
AI agents call performance.measure_response_latency to retrieve information from ContextForge MCP Gateway without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
Why performance.measure_response_latency is rated Low
This tool passively measures and reports on response latency metrics. It performs statistical analysis on existing timing data, which is a read-only monitoring activity. There is no code execution, data modification, deletion, or financial impact. The sibling tools (trackers, content/graph builders) reinforce that this is part of an observability/instrumentation suite.
From the tool's definition Tool name includes 'measure' and description states 'Track generation speed and response times with statistical analysis' — these are observational/monitoring operations that retrieve performance metrics without modifying, executing external code, or…
Attacks that exploit this kind of access
The rule that runs performance.measure_response_latency safely
PolicyLayer is an MCP gateway: it sits between your AI agents and ContextForge MCP Gateway, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For performance.measure_response_latency, this is the rule to start with:
performance.measure_response_latency 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 ContextForge MCP Gateway, apply this rule, and every performance.measure_response_latency call is checked against it from then on.
Questions about performance.measure_response_latency
Track generation speed and response times with statistical analysis. It is categorised as a Read tool in the ContextForge MCP Gateway MCP Server, which means it retrieves data without modifying state.
Register the ContextForge MCP Gateway MCP server in PolicyLayer and add a rule for performance.measure_response_latency: 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 ContextForge MCP Gateway. Nothing to install.
performance.measure_response_latency 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.measure_response_latency 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.measure_response_latency. 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.measure_response_latency is provided by the ContextForge MCP Gateway MCP server (jrmatherly/mcp-context-forge). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
