Find function definition in project
AI agents call find_function to retrieve information from Local Code 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 function definition information from a codebase without modifying, executing, or deleting anything. It is a pure read operation that enables code exploration. The broader server design confirms read-only semantics. Risk is low because the worst outcome is that an AI agent learns about function definitions, which cannot harm the system.
From the tool's definition Tool is described as 'Find function definition in project' and is explicitly part of a 'read-only access' server that provides 'searching, reading files, and finding function definitions'.
Attacks that exploit this kind of access
Find function definition in project. It is categorised as a Read tool in the Local Code MCP Server MCP Server, which means it retrieves data without modifying state.
Register the Local Code MCP Server MCP server in PolicyLayer and add a rule for find_function: 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 Local Code MCP Server. Nothing to install.
find_function 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 find_function 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 find_function. 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.
find_function is provided by the Local Code MCP Server MCP server (udittripathi/mcpserver). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
