http_request · LuzzyTool MCP: Risk & Policy

WHAT IT DOES

What http_request does on LuzzyTool

AI agents invoke http_request to trigger actions in LuzzyTool. What it does depends on the arguments the agent supplies, and its effects often reach beyond the immediate call — builds kicked off, notifications sent, workflows started.

WHY IT NEEDS A POLICY

Why http_request needs a policy

This tool can trigger arbitrary external HTTP operations including destructive DELETE requests, data-modifying PUT/PATCH/POST requests, and interactions with third-party APIs. Because it spans multiple categories (Read for GET, Write for POST/PUT, Destructive for DELETE), the most severe applicable category is Execute — it runs externally-directed operations whose effects depend entirely on the arguments supplied.

From the tool's definition 发送 HTTP 请求，支持 GET/POST/PUT/DELETE/PATCH/HEAD/OPTIONS — supports arbitrary HTTP methods including DELETE and PUT, plus API calls, file downloads, and external service interactions

Verdict

http_request Rate-limited

http_request stays usable, but rate-capped — a runaway agent can't fire it dozens of times a minute. Everything else on the server is denied unless you say otherwise.
