AI agents call dump_image 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.
The name 'dump_image' suggests capturing or reading image/screen data from an Android device, which would be a Read operation. In ADB context, this likely captures a screenshot or dumps a disk/partition image. If it's a screen capture, it's a Read with medium severity due to potential privacy implications. However, the empty description significantly lowers confidence.
From the tool's definition Tool name 'dump_image' on an ADB server; description is empty and uninformative.
Documented attack patterns abuse exactly the kind of access dump_image gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and ADB MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for dump_image:
{
"version": "1",
"default": "deny",
"tools": {
"dump_image": {}
}
}dump_image is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

dump_image. 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 dump_image: 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.
dump_image 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 dump_image 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 dump_image. 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.
dump_image is provided by the ADB MCP Server MCP server (srmorete/adb-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
