Get silent installation arguments for an application. Can look up by Winget package ID, installer type, or installer URL.
AI agents call get_silent_install_args to retrieve information from Packager-MCP 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 installation argument data for applications. It retrieves pre-existing information without creating, modifying, deleting, or executing anything. While the arguments themselves might later be used in destructive operations, the tool itself only performs read/lookup operations. The context of Windows application packaging does not change the fundamental nature of this retrieval function.
From the tool's definition Tool description states it 'Get[s] silent installation arguments' and performs lookups 'by Winget package ID, installer type, or installer URL' — purely retrieval operations with no modification of system state or execution of commands.
Attacks that exploit this kind of access
Get silent installation arguments for an application. Can look up by Winget package ID, installer type, or installer URL. It is categorised as a Read tool in the Packager-MCP MCP Server, which means it retrieves data without modifying state.
Register the Packager- MCP server in PolicyLayer and add a rule for get_silent_install_args: 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 Packager-MCP. Nothing to install.
get_silent_install_args 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 get_silent_install_args 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 get_silent_install_args. 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.
get_silent_install_args is provided by the Packager- MCP server (kkaminsk/packager-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
