AI agents call backtrace 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 backtrace function retrieves debugging information about the call stack for inspection purposes only. This is a read-only diagnostic operation with no side effects—it does not modify data, execute arbitrary code, delete anything, or trigger external operations. The moderate confidence reflects standard debugging semantics where backtrace is universally a non-destructive introspection tool.
From the tool's definition Tool name 'backtrace' and description 'Display program function backtrace' indicate a passive inspection operation that reads and presents stack trace information without modifying program state or executing code.
Documented attack patterns abuse exactly the kind of access backtrace 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 backtrace:
{
"version": "1",
"default": "deny",
"tools": {
"backtrace": {}
}
}backtrace is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Display program function backtrace. 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 backtrace: 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.
backtrace 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 backtrace 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 backtrace. 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.
backtrace 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.
