Get clipboard text (Android 10+).
AI agents call adb_clipboard to retrieve information from ADB MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool only retrieves data from the device's clipboard without creating, modifying, deleting, or executing any operations. It is a read-only query that returns existing information. While clipboard contents could theoretically contain sensitive data, the risk is passive data access rather than active harm.
From the tool's definition Tool description explicitly states "Get clipboard text" — a retrieval operation with no modification or side effects. The tool queries the clipboard state of an Android device.
Attacks that exploit this kind of access
Get clipboard text (Android 10+). It is categorised as a Read tool in the ADB MCP Server MCP Server, which means it retrieves data without modifying state.
Register the ADB MCP Server MCP server in PolicyLayer and add a rule for adb_clipboard: 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 ADB MCP Server. Nothing to install.
adb_clipboard 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_clipboard 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_clipboard. 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_clipboard is provided by the ADB MCP Server MCP server (lll-404/adb-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
