AI agents call heap to retrieve information from Pwndbg without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
The tool examines (reads/queries) heap memory in a debugged process. It retrieves heap state information without modifying or executing anything. Severity is medium because heap inspection in a debugger context can expose sensitive memory contents and is part of an exploit development workflow, but the tool itself only reads data.

Documented attack patterns abuse exactly the kind of access heap gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Pwndbg, and nothing reaches the server without passing your rules. This is the rule we recommend for heap:
{
"version": "1",
"default": "deny",
"tools": {
"heap": {}
}
}heap is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Examine heap with pwndbg. It is categorised as a Read tool in the Pwndbg MCP Server, which means it retrieves data without modifying state.
Register the Pwndbg MCP server in PolicyLayer and add a rule for heap: 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 Pwndbg. Nothing to install.
heap 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 heap 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 heap. 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.
heap is provided by the Pwndbg MCP server (rocketmadev/pwndbg-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
