AI agents call get_aur_info to retrieve information from Cachyos without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
get_aur_info queries the AUR (Arch User Repository) database to return package metadata such as dependencies, votes, popularity, and flags. This is purely informational retrieval with no side effects, no code execution, and no data modification. It falls squarely into the Read category.
From the tool's definition Tool retrieves 'Full AUR metadata for one package (deps, votes, popularity, flags)' — a read-only query operation with no modification or execution of system state.
Attacks that exploit this kind of access
Full AUR metadata for one package (deps, votes, popularity, flags). It is categorised as a Read tool in the Cachyos MCP Server, which means it retrieves data without modifying state.
Register the Cachyos MCP server in PolicyLayer and add a rule for get_aur_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 Cachyos. Nothing to install.
get_aur_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_aur_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_aur_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_aur_info is provided by the Cachyos MCP server (raindancer118/cachyos-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
