AI agents call adb_pull to retrieve information from Adb without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
adb_pull retrieves/copies a file from the Android device to the host machine without modifying or deleting the source. This is a read/fetch operation. Severity is medium because it can exfiltrate sensitive files from the device (credentials, private data, etc.) if misused.
From the tool's definition Pull a file from the device to the host. Returns the local path and file size.
Attacks that exploit this kind of access
Pull a file from the device to the host. Returns the local path and file size. Files are saved to /tmp/ by default. It is categorised as a Read tool in the Adb MCP Server, which means it retrieves data without modifying state.
Register the Adb MCP server in PolicyLayer and add a rule for adb_pull: 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. Nothing to install.
adb_pull 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_pull 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_pull. 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_pull is provided by the Adb MCP server (sfaizi24/adb-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
adb_pull is one line of Adb's registry record.
The record carries the whole server: verified identity, auth posture, risk grade, every tool classified, recommended policy — re-checked continuously.
