List all connected Android devices with model, Android version, and screen size.
AI agents call adb_devices to retrieve information from Claude Pascal MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool performs a read-only operation that queries and returns metadata about connected devices. There are no side effects, no code execution, no data modification, and no destructive actions. The blast radius of misuse is minimal — an attacker gains only informational inventory of connected devices, which is low-risk compared to other tools on this server (adb_install, adb_push, adb_launch_app, etc.).
From the tool's definition Tool description states it 'List all connected Android devices with model, Android version, and screen size' — a query operation that retrieves device information without modifying or executing anything.
Documented attack patterns abuse exactly the kind of access adb_devices gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Claude Pascal MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for adb_devices:
{
"version": "1",
"default": "deny",
"tools": {
"adb_devices": {}
}
}adb_devices is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.
Free to start. No card required.
List all connected Android devices with model, Android version, and screen size. It is categorised as a Read tool in the Claude Pascal MCP Server MCP Server, which means it retrieves data without modifying state.
Register the Claude Pascal MCP Server 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 Claude Pascal MCP Server. 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 Claude Pascal MCP Server MCP server (tina4stack/claude-pascal-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from Claude Pascal MCP Server, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
Free to start. No card required.
