WHAT IT DOES

What unidbg_emulate does on Jshookmcp

AI agents invoke unidbg_emulate to trigger actions in Jshookmcp. 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.

RISK

Why unidbg_emulate is rated High

Emulating native functions enables arbitrary code execution with unpredictable side effects and system access.

From the tool's definition Emulate native function with Unidbg; arbitrary code execution capability.

Attacks that exploit this kind of access

RECOMMENDED RULE

The rule that runs unidbg_emulate safely

PolicyLayer is an MCP gateway: it sits between your AI agents and Jshookmcp, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For unidbg_emulate, this is the rule to start with:

unidbg_emulate Rate-limited

unidbg_emulate 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.

The button opens the PolicyLayer dashboard: create your workspace, connect Jshookmcp, apply this rule, and every unidbg_emulate call is checked against it from then on.
