[DISCOVERY] Get information about an official Arch repository package (Core, Extra, etc.). Uses local pacman if available, otherwise queries archlinux.org API. Always prefer official packages over AUR when available. Example query:
AI agents call get_official_package_info to retrieve information from Arch Linux without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool performs informational queries about packages—fetching metadata from repositories. It has no side effects, does not modify system state, execute code, or delete data. It is a straightforward read operation that poses minimal risk if misused by an AI agent, as the worst outcome would be returning information about legitimate packages.

Documented attack patterns abuse exactly the kind of access get_official_package_info gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Arch Linux, and nothing reaches the server without passing your rules. This is the rule we recommend for get_official_package_info:
{
"version": "1",
"default": "deny",
"tools": {
"get_official_package_info": {}
}
}get_official_package_info is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Register the Arch Linux MCP server in PolicyLayer and add a rule for get_official_package_info: 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 Arch Linux. Nothing to install.
get_official_package_info 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_official_package_info 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_official_package_info. 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_official_package_info is provided by the Arch Linux MCP server (nihalxkumar/arch-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
