List all breakpoints currently set in the debugger.
AI agents call list_all_breakpoints to retrieve information from Dap without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool queries and returns information about existing breakpoints. It performs no mutations, does not execute code, and does not delete or modify any state. It is purely informational—a read operation with no side effects, making it the least risky category.
From the tool's definition Tool name 'list_all_breakpoints' and description 'List all breakpoints currently set in the debugger' indicate a query operation that retrieves breakpoint data without modifying, executing, or affecting debugger state.
Documented attack patterns abuse exactly the kind of access list_all_breakpoints gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Dap, and nothing reaches the server without passing your rules. This is the rule we recommend for list_all_breakpoints:
{
"version": "1",
"default": "deny",
"tools": {
"list_all_breakpoints": {}
}
}list_all_breakpoints is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

List all breakpoints currently set in the debugger. It is categorised as a Read tool in the Dap MCP Server, which means it retrieves data without modifying state.
Register the Dap MCP server in PolicyLayer and add a rule for list_all_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 Dap. Nothing to install.
list_all_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_all_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_all_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_all_breakpoints is provided by the Dap MCP server (kashuncheng/dap_mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from Dap, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
Free to start. No card required.
