WHAT IT DOES

What search_hn_jobs does on Jobs

AI agents call search_hn_jobs to retrieve information from Jobs without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

RISK

Why search_hn_jobs is rated Low

This tool retrieves or queries data from Hacker News job listings with no side effects, state changes, or destructive actions. It is a straightforward read operation consistent with other search tools on this server (search_upwork_jobs, search_github_jobs, search_remote_jobs). Low severity reflects minimal risk even if misused—an AI agent can only retrieve job data, which is already public.

From the tool's definition search_hn_jobs with description 'Search Hacker News' performs a query operation that retrieves job listings without modifying, deleting, or executing any code.
