// tools this server exposes9 tools

These names and descriptions are the publisher's own, read from the source code. We print them as written. Our assessment is the findings above, not this list.

search_deep

Perform deep research on a topic. Searches multiple sources, extracts citations, and synthesizes a comprehensive answer. Requires LLM sampling capability.

get_engines

Check currently configured default search engines

get_sampling

Check whether LLM sampling is currently enabled. When enabled, results are filtered by relevance using an LLM. Disabled by default.

search_web

Search the web using multiple engines (e.g., Google, Bing, Brave), merge results, and optionally filter by relevance using an LLM (sampling).

set_engines

Update default search engines and persist to .env

set_sampling

Enable or disable LLM-based relevance filtering for search results. When enabled, an LLM evaluates each result for relevance to the query. Requires either: (1) IDE/client with sampling support, OR (2) LLM_BASE_URL set (LLM_API_KEY optional for local models). Persists setting to .env

wait_for_timeout_notifications

Test tool: Waits for up to 10 minutes, sending progress notifications every 5 seconds. Logs behavior.

wait_for_timeout_silent

Test tool: Waits silently for up to 10 minutes to observe MCP client timeout behavior. Logs when cancelled.

visit_webpage

Dependencies

25 dependencies, 1 flagged: playwright-chromium

Tool annotations

No tools have read-only/destructive annotations

Add readOnlyHint or destructiveHint annotations to every tool so hosts can warn users before invoking.

All four hints declared on every tool

9/9 tools missing one or more hints — search_deep (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); get_engines (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); get_sampling (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint), +6 more. OpenAI's directory rejects tools where any of the four hints are missing or non-boolean.

For every tool, set all four hints (readOnlyHint, destructiveHint, idempotentHint, openWorldHint) to explicit true/false values that match the handler’s actual behaviour.

Tool inputs are validated

5/9 tool handlers declare input schemas (56%)

Declare an inputSchema with zod/joi/yup on every tool definition.

Tool handlers catch errors

5/9 tool handlers wrap calls in try/catch (56%)

Wrap each tool handler body in try/catch and return a structured error response.

Tests exist

No test files found

Add tests that exercise each declared tool.

Production dependencies are patched

0 critical, 3 high severity in production deps — @modelcontextprotocol/sdk@1.11.2 (high), @modelcontextprotocol/sdk@1.11.2 (high)

Run npm audit fix, or upgrade the affected packages to a non-vulnerable version.

Dev dependencies

1 critical/high in dev-only deps (does not ship to users)

Upgrade dev dependencies when convenient.

// full audit trail
The findings above are the summary. The full trail, every check we ran, each deduction, the network hosts observed and the dependency advisories, goes to verified publishers, along with an alert whenever a new one lands. Verified publishers can also review each finding and dispute it in one click. Publisher corrections have sharpened several of our checks this month, because the maintainer knows the codebase better than any scanner.
// improvement guidance — verified publishers only
We have 7 concrete improvements we can share with the publisher of this MCP. Each comes with specific guidance to raise the trust score.
