Read CPU register values of the active thread. REQUIRES: state=
AI agents call get_registers 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 only queries and retrieves the current state of CPU registers from the debugged process. It performs no modifications, does not execute code or trigger external operations, and cannot delete or alter data. The read-only nature and lack of destructive capability place it firmly in the Read category with low severity, as exposing register values carries minimal risk even in an uncontrolled debugging context.
From the tool's definition Tool name 'get_registers' and description 'Read CPU register values' explicitly indicate a read-only operation that retrieves current processor state without modification or side effects.
Attacks that exploit this kind of access
Read CPU register values of the active 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_registers: 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_registers 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_registers 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_registers. 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_registers 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.
