Search for specific classes, functions, or constants across Endstone modules
AI agents call search_exports to retrieve information from Endstone 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 information about code exports (classes, functions, constants) from the Endstone development framework. It performs a search query across module definitions and returns matching results. No side effects, data modification, code execution, or resource consumption occurs.
From the tool's definition Tool description explicitly states it 'Search[es] for specific classes, functions, or constants across Endstone modules' — a pure query/search operation with no modification or execution capability.
Attacks that exploit this kind of access
Search for specific classes, functions, or constants across Endstone modules. It is categorised as a Read tool in the Endstone MCP Server MCP Server, which means it retrieves data without modifying state.
Register the Endstone MCP Server MCP server in PolicyLayer and add a rule for search_exports: 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 Endstone MCP Server. Nothing to install.
search_exports 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_exports 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_exports. 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_exports is provided by the Endstone MCP Server MCP server (mcayear/mcp-server-endstone). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
