List all active breakpoints
AI agents call debugger_list_breakpoints to retrieve information from CDP-MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool queries the current state of breakpoints in the Chrome DevTools Protocol debugger. It performs no side effects, makes no modifications to code or data, and does not execute operations. It is purely a diagnostic query operation, falling squarely into the Read category.
From the tool's definition Tool name 'debugger_list_breakpoints' and description 'List all active breakpoints' indicate a read-only operation that retrieves debugging state without modifying or executing anything.
Attacks that exploit this kind of access
List all active breakpoints. It is categorised as a Read tool in the CDP-MCP Server MCP Server, which means it retrieves data without modifying state.
Register the CDP-MCP Server MCP server in PolicyLayer and add a rule for debugger_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 CDP-MCP Server. Nothing to install.
debugger_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 debugger_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 debugger_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.
debugger_list_breakpoints is provided by the CDP-MCP Server MCP server (jekyll-001/cdp-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
