AI agents call vmmap 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.
This is a passive information-gathering tool used in debugging workflows. It retrieves memory layout information (virtual memory maps) from the debugged process similar to /proc/[pid]/maps on Linux. This is a standard Read category operation—no side effects, no code execution, no data modification.
From the tool's definition The tool "Display current program memory layout or pages match pattern" performs read-only retrieval of memory mapping information from a debugged process. It queries and returns data about the target binary's memory layout without modifying or executing code.
Documented attack patterns abuse exactly the kind of access vmmap 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 vmmap:
{
"version": "1",
"default": "deny",
"tools": {
"vmmap": {}
}
}vmmap is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Display current program memory layout or pages match pattern. 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 vmmap: 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.
vmmap 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 vmmap 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 vmmap. 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.
vmmap 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.
