在 Stata GUI 中显示上一次命令的 r() 或 e() 存储结果
AI agents call stata_get_results to retrieve information from Stata without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
The tool retrieves result values that have already been computed by prior Stata commands. It displays stored results (r() and e() macros in Stata terminology) without executing new code, modifying data, or triggering side effects. This is a pure data retrieval operation, fitting the Read category. Severity is low because accessing stored numerical or statistical results poses minimal risk even if misused by an agent.
From the tool's definition Tool name 'stata_get_results' and description indicate retrieval of previously computed r() or e() stored results from Stata—a read-only operation that queries existing results without modification, deletion, or code execution.
Documented attack patterns abuse exactly the kind of access stata_get_results gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Stata, and nothing reaches the server without passing your rules. This is the rule we recommend for stata_get_results:
{
"version": "1",
"default": "deny",
"tools": {
"stata_get_results": {}
}
}stata_get_results is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

在 Stata GUI 中显示上一次命令的 r() 或 e() 存储结果. It is categorised as a Read tool in the Stata MCP Server, which means it retrieves data without modifying state.
Register the Stata MCP server in PolicyLayer and add a rule for stata_get_results: 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 Stata. Nothing to install.
stata_get_results 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 stata_get_results 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 stata_get_results. 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.
stata_get_results is provided by the Stata MCP server (shichengg/stata-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from Stata, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
