Why clear_all_breakpoints needs a policy

This tool modifies the debugging state by removing all breakpoints, but this is a reversible action — breakpoints can be re-added. It doesn't execute code, delete data, or have financial impact. The blast radius is low: misuse disrupts a debugging session but causes no lasting harm.

From the tool's definition Remove all active JavaScript breakpoints on the current page

POLICY

How to control clear_all_breakpoints

PolicyLayer is an MCP gateway — it sits between your AI agents and ReverseCraft DevTools MCP, and nothing reaches the server without passing your rules. This is the rule we recommend for clear_all_breakpoints:

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "clear_all_breakpoints": {
      "limits": [
        {
          "counter": "clear_all_breakpoints_rate",
          "window": "minute",
          "max": 30,
          "scope": "grant"
        }
      ]
    }
  }
}

clear_all_breakpoints stays usable, but capped — an agent stuck in a loop can't make hundreds of changes a minute. Everything else on the server is denied unless you say otherwise.
