AI agents call get_xrefs_from to retrieve information from GhidraMCP without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
Cross-reference retrieval is a read-only operation that queries the binary analysis database without modifying, executing, or deleting anything. It returns analytical metadata useful for reverse engineering but produces no side effects. Low severity because misuse reveals only structural information about a binary, not financial, destructive, or code execution risks.
From the tool's definition Tool name 'get_xrefs_from' indicates retrieval of cross-references (xrefs) from a location in binary analysis.
Attacks that exploit this kind of access
get_xrefs_from. It is categorised as a Read tool in the GhidraMCP MCP Server, which means it retrieves data without modifying state.
Register the Ghidra MCP server in PolicyLayer and add a rule for get_xrefs_from: 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 GhidraMCP. Nothing to install.
get_xrefs_from 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_xrefs_from 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_xrefs_from. 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_xrefs_from is provided by the Ghidra MCP server (pr0cf5/ghidramcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
