debugger_step_out · CDP-MCP Server MCP: Risk & Policy

WHAT IT DOES

What debugger_step_out does on CDP-MCP Server

AI agents invoke debugger_step_out to trigger actions in CDP-MCP Server. 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.

WHY IT NEEDS A POLICY

Why debugger_step_out needs a policy

This tool controls debugger execution flow by stepping out of the current function, which directly manipulates a running program's execution state. It falls under Execute because it triggers an external operation (resuming/changing execution in the attached browser/process) whose effects depend on the current debugging context.

debugger_step_out Rate-limited

debugger_step_out 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.

What risk level is debugger_step_out? +

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

Can I rate-limit debugger_step_out? +

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

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