WHAT IT DOES

What adb_multi_shell does on Deepadb

AI agents invoke adb_multi_shell 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_multi_shell is rated High

This tool runs arbitrary shell commands on Android devices, which can perform any operation the shell permits. The parallel execution across multiple devices amplifies the blast radius. While not inherently destructive (depends on the command), shell execution is classified as Execute per the rules.

From the tool's definition Tool description states: 'Execute a shell command on multiple (or all) connected devices in parallel.' The verb 'Execute' combined with 'shell command' directly indicates code execution capability.

Attacks that exploit this kind of access

RECOMMENDED RULE

The rule that runs adb_multi_shell 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_multi_shell, this is the rule to start with:

adb_multi_shell Rate-limited

adb_multi_shell 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.

RATE-LIMIT THIS TOOL → Instant setup, no code required.

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

FAQ

Questions about adb_multi_shell

What does the adb_multi_shell tool do? +

Execute a shell command on multiple (or all) connected devices in parallel. Returns results grouped by device. 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_multi_shell? +

Register the Deepadb MCP server in PolicyLayer and add a rule for adb_multi_shell: 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_multi_shell? +

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

Can I rate-limit adb_multi_shell? +

Yes. Add a rate_limit block to the adb_multi_shell 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_multi_shell completely? +

Set action: deny in the PolicyLayer policy for adb_multi_shell. 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_multi_shell? +

adb_multi_shell 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.
