Read raw bytes from the debuggee
AI agents call read_memory 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 retrieves memory contents from a debugged process without modifying, deleting, or executing anything. While it operates in a debugger context and could reveal sensitive information (lowering confidence slightly below perfect), the action itself is fundamentally a read operation.
From the tool's definition Tool name is 'read_memory' and description states it 'Read raw bytes from the debuggee' — a query operation with no side effects.
Attacks that exploit this kind of access
Read raw bytes from the debuggee. 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 read_memory: 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.
read_memory 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 read_memory 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 read_memory. 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.
read_memory 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.
