What adb_unroot does on Ya Frida
AI agents invoke adb_unroot to trigger actions in Ya Frida. 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_unroot is rated High
This tool executes a command that restarts a system service (adbd) on a connected Android device, changing its privilege level. While not destructive (the change is reversible by calling adb_root or restarting the device), it is an active operation that modifies system state and triggers external execution on the target device.
From the tool's definition Tool name 'adb_unroot' and description 'Restart adbd without root permissions' indicate this triggers a restart operation on the Android Debug Bridge daemon, which is an external system operation with side effects.

The rule that runs adb_unroot safely
PolicyLayer is an MCP gateway: it sits between your AI agents and Ya Frida, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For adb_unroot, this is the rule to start with:
adb_unroot 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 Ya Frida, apply this rule, and every adb_unroot call is checked against it from then on.
Questions about adb_unroot
Restart adbd without root permissions. It is categorised as a Execute tool in the Ya Frida MCP Server, which means it can trigger actions or run processes. Use rate limits and argument validation.
Register the Ya Frida MCP server in PolicyLayer and add a rule for adb_unroot: 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 Ya Frida. Nothing to install.
adb_unroot 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_unroot 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_unroot. 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_unroot is provided by the Ya Frida MCP server (1shin-7/ya-frida-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
