What list_breakpoints does on Js Reverse
AI agents call list_breakpoints to retrieve information from Js Reverse without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
Why list_breakpoints is rated Low
This tool queries and returns information about existing breakpoints—a passive inspection of debugger state. It has no side effects, does not execute code, modify data, or trigger external operations. The broader server context (browser control, debugging, reverse engineering) carries execution risk, but this specific tool is a safe information retrieval operation typical of debugging interfaces.
From the tool's definition Tool name 'list_breakpoints' and description 'Lists all active breakpoints in the current debugging session' indicate a read-only operation that retrieves debugging state without modifying or executing code.
Attacks that exploit this kind of access
The rule that runs list_breakpoints safely
PolicyLayer is an MCP gateway: it sits between your AI agents and Js Reverse, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For list_breakpoints, this is the rule to start with:
list_breakpoints is read-only, so it stays allowed. Everything else on the server is denied unless you say otherwise.
The button opens the PolicyLayer dashboard: create your workspace, connect Js Reverse, apply this rule, and every list_breakpoints call is checked against it from then on.
Questions about list_breakpoints
Lists all active breakpoints in the current debugging session. It is categorised as a Read tool in the Js Reverse MCP Server, which means it retrieves data without modifying state.
Register the Js Reverse MCP server in PolicyLayer and add a rule for list_breakpoints: 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 Js Reverse. Nothing to install.
list_breakpoints is a Read tool with low risk. Read-only tools are generally safe to allow by default.
Yes. Add a rate_limit block to the list_breakpoints 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.
Set action: deny in the PolicyLayer policy for list_breakpoints. 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.
list_breakpoints is provided by the Js Reverse MCP server (1600822305/js-reverse-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
