WHAT IT DOES

What adb_file_chmod does on Deepadb

AI agents invoke adb_file_chmod to trigger actions in Deepadb. What it does depends on the arguments the agent supplies, and its effects often reach beyond the immediate call: builds kicked off, notifications sent, workflows started.

RISK

Why adb_file_chmod is rated High

chmod modifies file permission bits on a remote Android device via ADB. While it doesn't delete data, it executes a privileged system operation that can expose sensitive files (e.g., chmod 777 on /data files) or lock out legitimate access. This is an Execute-category action with high blast radius if misused by an AI agent.

RECOMMENDED RULE

The rule that runs adb_file_chmod 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_file_chmod, this is the rule to start with:

adb_file_chmod Rate-limited

adb_file_chmod stays usable, but rate-capped: a runaway agent can't fire it dozens of times a minute. 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_file_chmod call is checked against it from then on.

FAQ

Questions about adb_file_chmod

What does the adb_file_chmod tool do? +

Change file permissions on the device. Mode must be a valid octal string (e.g.,. It is categorised as a Execute tool in the Deepadb MCP Server, which means it can trigger actions or run processes. Use rate limits and argument validation.

How do I enforce a policy on adb_file_chmod? +

Register the Deepadb MCP server in PolicyLayer and add a rule for adb_file_chmod: 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.

What risk level is adb_file_chmod? +

adb_file_chmod is a Execute tool with high risk. Execute tools should be rate-limited and have argument validation enabled.

Can I rate-limit adb_file_chmod? +

Yes. Add a rate_limit block to the adb_file_chmod 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.

How do I block adb_file_chmod completely? +

Set action: deny in the PolicyLayer policy for adb_file_chmod. 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.

What MCP server provides adb_file_chmod? +

adb_file_chmod 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.
