What adb_devices does on Ya Frida
AI agents call adb_devices to retrieve information from Ya Frida without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
Why adb_devices is rated Low
This tool performs a simple enumeration/listing of connected devices and their metadata. It has no side effects, does not modify state, does not execute code, and does not access sensitive data beyond what is already known to the user (device list). The blast radius of misuse is minimal—an agent could only gain visibility into connected devices, which is informational only.
From the tool's definition Tool name 'adb_devices' and description 'List all ADB-connected devices with their state and properties' indicate a read-only operation that retrieves device information without modification, deletion, or execution of code.
Attacks that exploit this kind of access
The rule that runs adb_devices 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_devices, this is the rule to start with:
adb_devices is read-only, so it stays allowed. 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_devices call is checked against it from then on.
Questions about adb_devices
List all ADB-connected devices with their state and properties. It is categorised as a Read tool in the Ya Frida MCP Server, which means it retrieves data without modifying state.
Register the Ya Frida MCP server in PolicyLayer and add a rule for adb_devices: 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_devices is a Read tool with low risk. Read-only tools are generally safe to allow by default.
Yes. Add a rate_limit block to the adb_devices 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_devices. 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_devices 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.
