获取所有 CPU 寄存器
AI agents call get_registers to retrieve information from WinDbg GUI MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves CPU register values from a running or paused debuggee process in WinDbg. It has no side effects—it only reads and returns register state. Even in the context of a debugger, reading registers is a diagnostic read-only operation. The worst-case misuse is information disclosure (register contents might include sensitive pointers or data), but no modification, execution, or destruction is possible.
From the tool's definition Tool name 'get_registers' and description '获取所有 CPU 寄存器' (get all CPU registers) indicate pure data retrieval.
Attacks that exploit this kind of access
获取所有 CPU 寄存器. It is categorised as a Read tool in the WinDbg GUI MCP Server MCP Server, which means it retrieves data without modifying state.
Register the WinDbg GUI 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 WinDbg GUI 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 WinDbg GUI MCP Server MCP server (jianqiaojia/windbg-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
