What adb_cat does on Deepadb
AI agents call adb_cat 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.
Why adb_cat is rated Low
This tool retrieves file contents from an Android device without side effects. It is a query operation analogous to Unix 'cat' command. The lowest severity applies since reading files has minimal blast radius unless the device contains highly sensitive data, but the operation itself is non-destructive and non-modifying.
From the tool's definition Tool name 'adb_cat' and description 'Read a text file from the device' both indicate file reading with no modification.
Attacks that exploit this kind of access
The rule that runs adb_cat 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_cat, this is the rule to start with:
adb_cat is read-only, so it stays allowed. Everything else on the server is denied unless you say otherwise.
The button opens the PolicyLayer dashboard: create your workspace, connect Deepadb, apply this rule, and every adb_cat call is checked against it from then on.
Questions about adb_cat
Read a text file from the device. It is categorised as a Read tool in the Deepadb MCP Server, which means it retrieves data without modifying state.
Register the Deepadb MCP server in PolicyLayer and add a rule for adb_cat: 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 Deepadb. Nothing to install.
adb_cat 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_cat 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_cat. 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_cat is provided by the Deepadb MCP server (deepadb). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
