List installed packages, optionally filtered
AI agents call list_packages to retrieve information from Enhanced ADB MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool queries and returns information about installed packages on an Android device. It performs no write, destructive, execute, or financial operations—it is purely an informational read operation. The optional filtering is a query parameter, not a state-changing action. Blast radius is minimal; listing packages cannot harm device integrity or data.
From the tool's definition Tool name 'list_packages' and description 'List installed packages, optionally filtered' indicates data retrieval with no modification or side effects.
Attacks that exploit this kind of access
List installed packages, optionally filtered. It is categorised as a Read tool in the Enhanced ADB MCP Server MCP Server, which means it retrieves data without modifying state.
Register the Enhanced ADB MCP Server MCP server in PolicyLayer and add a rule for list_packages: 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 Enhanced ADB MCP Server. Nothing to install.
list_packages 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 list_packages 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 list_packages. 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.
list_packages is provided by the Enhanced ADB MCP Server MCP server (rahulkr/r_adb_mcp_server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
