AI agents call get_package_dependencies 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.
This tool queries and returns package dependency metadata without side effects. Both forward dependency resolution and reverse dependency lookup (who-needs-it) are read operations. The use of pactree, a standard informational utility, confirms this is data retrieval only.
From the tool's definition Tool retrieves dependency information using pactree, a query-only tool. Description indicates it 'gets' dependency tree data with optional reverse lookup. No modification, execution, deletion, or financial impact.
Attacks that exploit this kind of access
Dependency tree of a package (pactree). reverse=True for who-needs-it. 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_package_dependencies: 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_package_dependencies 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_package_dependencies 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_package_dependencies. 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_package_dependencies 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.
