What adb_qemu_setup does on Deepadb
AI agents invoke adb_qemu_setup to trigger actions in Deepadb. 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 adb_qemu_setup is rated High
This tool can install software (QEMU) on the device via a package manager, which is a system-modifying operation. Installing software triggers external operations and modifies device state. While the read/check portions are benign, the install capability elevates this to Execute since it runs package manager commands and installs virtualization software on the device.
From the tool's definition 'install QEMU via Termux package manager' and 'Check and install QEMU for on-device virtualization'
Attacks that exploit this kind of access
The rule that runs adb_qemu_setup safely
PolicyLayer is an MCP gateway: it sits between your AI agents and Deepadb, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For adb_qemu_setup, this is the rule to start with:
adb_qemu_setup 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 Deepadb, apply this rule, and every adb_qemu_setup call is checked against it from then on.
Questions about adb_qemu_setup
Check and install QEMU for on-device virtualization. Verifies KVM availability, checks if QEMU is installed, reports version info, and can install QEMU via Termux package manager. Only available in on-device mode. It is categorised as a Execute tool in the Deepadb MCP Server, which means it can trigger actions or run processes. Use rate limits and argument validation.
Register the Deepadb MCP server in PolicyLayer and add a rule for adb_qemu_setup: 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 Deepadb. Nothing to install.
adb_qemu_setup is a Execute tool with high risk. Execute tools should be rate-limited and have argument validation enabled.
Yes. Add a rate_limit block to the adb_qemu_setup 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 adb_qemu_setup. 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.
adb_qemu_setup is provided by the Deepadb MCP server (deepadb). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
