AI agents call search_functions_by_name 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.
This tool retrieves information about functions matching a search criteria. It has no side effects—it only queries and returns data from the reverse engineering analysis. It does not execute code, modify binaries, delete data, or trigger external operations.
From the tool's definition Tool 'search_functions_by_name' performs a substring search query across function definitions to retrieve matching results. The description indicates retrieval/query functionality with no modification, deletion, or execution of code.
Attacks that exploit this kind of access
Search for functions whose name contains the given substring. 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 search_functions_by_name: 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.
search_functions_by_name 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 search_functions_by_name 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 search_functions_by_name. 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.
search_functions_by_name 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.
