WHAT IT DOES

What adb_farm_matrix does on Deepadb

AI agents call adb_farm_matrix to retrieve information from Deepadb without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

RISK

Why adb_farm_matrix is rated Low

This tool queries Firebase Test Lab infrastructure to retrieve information about available testing devices and API levels. While it is fundamentally a Read operation (no data creation, modification, deletion, or code execution), the severity is elevated to 'high' because: (1) it exposes organizational testing infrastructure details that could inform attack planning, (2) it reveals which device/OS combinations are…

From the tool's definition Tool description states it 'List[s] available device models and API levels on Firebase Test Lab', which is a retrieval operation with no side effects. The verb 'List' is a classic Read operation pattern.

Attacks that exploit this kind of access

RECOMMENDED RULE

The rule that runs adb_farm_matrix safely

PolicyLayer is an MCP gateway: it sits between your AI agents and Deepadb, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For adb_farm_matrix, this is the rule to start with:

adb_farm_matrix Allowed

adb_farm_matrix is read-only, so it stays allowed. Everything else on the server is denied unless you say otherwise.

View as policy code

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "adb_farm_matrix": {}
  }
}

ALLOW ONLY THIS TOOL → Instant setup, no code required.

The button opens the PolicyLayer dashboard: create your workspace, connect Deepadb, apply this rule, and every adb_farm_matrix call is checked against it from then on.
