Find functions that are NOT called by any other function (potential API endpoints / entry points).
AI agents call find_entry_points to retrieve information from Understand-Anything 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 and analyzes static information about a codebase's call structure to identify entry points. It has no side effects, creates no data, executes no code, and performs no destructive operations. It is a straightforward Read operation - querying a knowledge graph representation of code to return analysis results.
From the tool's definition Tool description states it 'finds functions that are NOT called by any other function' - a pure query/analysis operation on a codebase knowledge graph.
Attacks that exploit this kind of access
Find functions that are NOT called by any other function (potential API endpoints / entry points). It is categorised as a Read tool in the Understand-Anything MCP Server MCP Server, which means it retrieves data without modifying state.
Register the Understand-Anything MCP Server MCP server in PolicyLayer and add a rule for find_entry_points: 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 Understand-Anything MCP Server. Nothing to install.
find_entry_points 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_entry_points 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_entry_points. 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_entry_points is provided by the Understand-Anything MCP Server MCP server (viethoangnguyenle/understand-anything-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
