⚠ Security warnings

Found during our hands-on test. Read before letting an agent use this tool unattended.

Very new project (repository created Oct 18, 2026).
The project publicly lists its own unresolved request-forgery and resource-limit findings in page fetching; keep page fetching off or contained if that matters to you.
It has a self-update command that replaces its own executable.
The default DEBUG log level records search terms and upstream request addresses.

What an agent would use this for

Gives an agent web search without an API key: run your own metasearch server and query it over a JSON API or MCP, with result limits, engine and domain filters, and optional page text for results it found.

How we tested

Method: Lab run of the release binary in a sandbox with a throwaway home, bound to loopback, with network on so it could reach public search engines: health check, JSON searches with filters, the page-text option, the stdio MCP server, and edge cases. Filed as field report r_f1de2295fb774982.. Tester: Lab Tester (lab account). Date: 2026-11-03T22:28:38-08:00.

Test log (from our notes)

What works

The release binary started on loopback with a working health check. JSON searches returned relevant results in about 3 seconds
and the result limit
single-engine filter and domain filter worked. The MCP server (stdio) listed two read-only tools
search and read_page
and a real search returned sensible results. MCP errors are clear: empty queries
out-of-range limits and unknown fields are rejected with helpful messages
and read_page refuses pages that search didn't return in the session.

What breaks

The HTTP API silently ignores bad parameters: an unknown engine name falls back to all default engines
max_results outside the documented 1-200 range is clamped without warning
and an invalid time_range is ignored. Errors aren't JSON even when JSON is requested (an HTML 400 page for a missing query
plain text for a non-numeric max_results). Failed page-text fetches just omit the field with no error. MCP uses limit (1-10) while HTTP uses max_results
and MCP can't choose engines. Many upstream engines failed on every query (CAPTCHAs
rate limits
access denied)
so results came from roughly half a dozen engines. The default log level is DEBUG and logs search terms.

Quality score

3/5 — our hands-on rating on a 1–5 scale, scored by the published rubric.

Partial 3/5: search over JSON and MCP works with clear MCP errors, but the HTTP API ignores bad parameters silently, returns non-JSON errors, and many upstream engines were blocked.
