WHAT IT DOES

What browser_cpu_profile_stop does on Jshookmcp

AI agents invoke browser_cpu_profile_stop 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 browser_cpu_profile_stop is rated High

Stops an active browser profiling session and writes artifacts to disk.

From the tool's definition stop CDP CPU profiling, rank hot functions, persist raw profile

RECOMMENDED RULE

The rule that runs browser_cpu_profile_stop 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 browser_cpu_profile_stop, this is the rule to start with:

browser_cpu_profile_stop Rate-limited

browser_cpu_profile_stop 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 browser_cpu_profile_stop call is checked against it from then on.

FAQ

Questions about browser_cpu_profile_stop

What does the browser_cpu_profile_stop tool do? +

Atomic primitive: stop CDP CPU profiling, rank hot functions by sample count, and persist the raw profile to artifacts/profiles/ (or a custom path). The hot function list is derived from the samples array — modern Chrome profiles do not populate hitCount. Fails clearly if profiling was never started. 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 browser_cpu_profile_stop? +

Register the Jshook MCP server in PolicyLayer and add a rule for browser_cpu_profile_stop: 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 browser_cpu_profile_stop? +

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

Can I rate-limit browser_cpu_profile_stop? +

Yes. Add a rate_limit block to the browser_cpu_profile_stop 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 browser_cpu_profile_stop completely? +

Set action: deny in the PolicyLayer policy for browser_cpu_profile_stop. 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 browser_cpu_profile_stop? +

browser_cpu_profile_stop 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.
