WHAT IT DOES

What network_rtt_measure does on Jshookmcp

AI agents invoke network_rtt_measure to trigger actions in Jshookmcp. What it does depends on the arguments the agent supplies, and its effects often reach beyond the immediate call: builds kicked off, notifications sent, workflows started.

RISK

Why network_rtt_measure is rated High

Triggers external network requests to arbitrary URLs, constituting an external operation.

RECOMMENDED RULE

The rule that runs network_rtt_measure safely

PolicyLayer is an MCP gateway: it sits between your AI agents and Jshookmcp, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For network_rtt_measure, this is the rule to start with:

network_rtt_measure Rate-limited

network_rtt_measure stays usable, but rate-capped: a runaway agent can't fire it dozens of times a minute. Everything else on the server is denied unless you say otherwise.

The button opens the PolicyLayer dashboard: create your workspace, connect Jshookmcp, apply this rule, and every network_rtt_measure call is checked against it from then on.

FAQ

Questions about network_rtt_measure

What does the network_rtt_measure tool do? +

Measure round-trip time to a target URL. It is categorised as a Execute tool in the Jshookmcp MCP Server, which means it can trigger actions or run processes. Use rate limits and argument validation.

How do I enforce a policy on network_rtt_measure? +

Register the Jshook MCP server in PolicyLayer and add a rule for network_rtt_measure: 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 Jshookmcp. Nothing to install.

What risk level is network_rtt_measure? +

network_rtt_measure is a Execute tool with high risk. Execute tools should be rate-limited and have argument validation enabled.

Can I rate-limit network_rtt_measure? +

Yes. Add a rate_limit block to the network_rtt_measure 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.

How do I block network_rtt_measure completely? +

Set action: deny in the PolicyLayer policy for network_rtt_measure. 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.

What MCP server provides network_rtt_measure? +

network_rtt_measure is provided by the Jshook MCP server (@jshookmcp/jshook). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
