// key findings
✅
Up to 9 tools verified — handlers match their declared behaviour
8 read-only tools verified — handlers contain no write/delete/exec 9 tools are registered in this MCP's source. You may see fewer than that, currently 2, depending on how the server is configured and which version you install. Some MCPs keep part of their tool surface behind a setting, and some ship more than one server.
✅
No credential exfiltration, no sensitive file access, no obfuscation
Static analysis found nothing flowing your secrets to unexpected places.
✅
Open source with a license and README
Anyone can audit the code, the license is declared, and the publisher documents what it does.
🔐
You'll be asked for 4 credentials: EXA_API_KEY, KV_REST_API_TOKEN, OPENAI_APPS_CHALLENGE_TOKEN, UPSTASH_REDIS_REST_TOKEN
These are read from process.env at runtime. Make sure you trust where they’ll be sent.
// known CVEs in dependencies2 low

All four hints declared on every tool

8/9 tools missing one or more hints — agent_run (missing: openWorldHint); company_research_exa (missing: openWorldHint); deep_researcher_check (missing: openWorldHint), +5 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

Only 4/9 tool handlers declare input schemas (44%)

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

// 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 2 concrete improvements we can share with the publisher of this MCP. Each comes with specific guidance to raise the trust score.
