chrome-debugger-mcp Execute Risk 3/5

AI agents invoke waitForPause to trigger processes or run actions in Chrome Debugger MCP. Execute operations can have side effects beyond the immediate call -- triggering builds, sending notifications, or starting workflows. Rate limits and argument validation are essential to prevent runaway execution.

waitForPause can trigger processes with real-world consequences. An uncontrolled agent might start dozens of builds, send mass notifications, or kick off expensive compute jobs. Intercept enforces rate limits and validates arguments to keep execution within safe bounds.

Execute tools trigger processes. Rate-limit and validate arguments to prevent unintended side effects.

What does the waitForPause tool do? +

[STEP 5b — FALLBACK] BLOCKING call — waits until ANY debugger pause occurs (breakpoint, debugger; statement, or exception). Before blocking, sends a notification to the user to trigger the page action. Must be called IMMEDIATELY after reloadPage() in the SAME AI turn — do NOT end your turn before calling this. Prefer waitForSpecificPause when you know the exact file and line — it uses smarter two-tier matching. Use this only when the target location is unknown or when setBreakpoint is used without a specific line.. It is categorised as a Execute tool in the Chrome Debugger MCP MCP Server, which means it can trigger actions or run processes. Use rate limits and argument validation.

How do I enforce a policy on waitForPause? +

Add a rule in your Intercept YAML policy under the tools section for waitForPause. You can allow, deny, rate-limit, or validate arguments. Then run Intercept as a proxy in front of the Chrome Debugger MCP MCP server.

What risk level is waitForPause? +

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

Can I rate-limit waitForPause? +

Yes. Add a rate_limit block to the waitForPause rule in your Intercept 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 waitForPause completely? +

Set action: deny in the Intercept policy for waitForPause. 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 waitForPause? +

waitForPause is provided by the Chrome Debugger MCP MCP server (chrome-debugger-mcp). Intercept sits as a proxy in front of this server to enforce policies before tool calls reach the server.
