Get the call stack (backtrace) of the current thread. REQUIRES: state=
AI agents call get_call_stack to retrieve information from x64dbg 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 existing debugging information without creating, modifying, deleting, or executing any code. It performs a passive inspection of the call stack, which is a non-destructive read operation.
From the tool's definition Tool retrieves call stack information (backtrace) of the current thread with no modification of state or executable behavior. Name and description indicate read-only introspection of debugger state.
Attacks that exploit this kind of access
Get the call stack (backtrace) of the current thread. REQUIRES: state=. It is categorised as a Read tool in the x64dbg MCP Server MCP Server, which means it retrieves data without modifying state.
Register the x64dbg MCP Server MCP server in PolicyLayer and add a rule for get_call_stack: 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 x64dbg MCP Server. Nothing to install.
get_call_stack 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 get_call_stack 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 get_call_stack. 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.
get_call_stack is provided by the x64dbg MCP Server MCP server (ouonet/x64dbg-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
