build_apk · APK Security Guard MCP Suite MCP: Risk & Policy

WHAT IT DOES

What build_apk does on APK Security Guard MCP Suite

AI agents invoke build_apk to trigger actions in APK Security Guard MCP Suite. 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 build_apk needs a policy

Building an APK involves executing a build process (compilation, packaging) that runs external tools/commands to produce a binary artifact. It is not merely reading or writing data—it triggers an execution pipeline. The blast radius is medium: it can produce modified APKs but does not directly delete data or move money.

build_apk Rate-limited

build_apk 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.
