What adb_root does on Ya Frida
AI agents invoke adb_root 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_root is rated High
Restarting adbd (Android Debug Bridge daemon) with root permissions is an Execute action that triggers a critical system operation. While it doesn't permanently delete data (Destructive) or move money (Financial), it executes a command that grants root-level access to a device, fundamentally altering its security state and enabling subsequent operations with maximum privileges.
From the tool's definition Tool description states 'Restart adbd with root permissions' - this triggers restart of the Android debug daemon with elevated privileges, a system-level operation that fundamentally changes the device's security posture and enables unrestricted access to…

The rule that runs adb_root 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_root, this is the rule to start with:
adb_root 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_root call is checked against it from then on.
Questions about adb_root
Restart adbd with 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_root: 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_root 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_root 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_root. 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_root 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.
