Find all cross-references (xrefs) to or from an address.
AI agents call get_cross_references 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 the debugger's internal cross-reference graph to locate references between addresses. It performs no modifications, executions, or side effects — it only retrieves and returns analysis data already computed by the debugger. The capability is informational only, suitable for understanding code structure during reverse engineering.
From the tool's definition Tool description states 'Find all cross-references (xrefs) to or from an address' — a query operation that retrieves existing analysis data without modifying or executing code. Cross-reference analysis is a standard read-only reverse engineering operation.
Attacks that exploit this kind of access
Find all cross-references (xrefs) to or from an address. 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_cross_references: 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_cross_references 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_cross_references 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_cross_references. 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_cross_references 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.
