// key findings

⚠️

Known vulnerabilities in dependencies: 13 high

Affects packages this MCP installs at runtime. Upgrade or remove the affected dependency.

✅

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 10 credentials: OPENAI_API_KEY, OPENROUTER_API_KEY, STRIPE_SECRET_KEY, STRIPE_WEBHOOK_SECRET, UPSTASH_REDIS_REST_TOKEN, ZKSHARE_API_KEY, ZKSHARE_ENCLAVE_JWT_SECRET, ZKSHARE_ENCRYPTION_SECRET, ZKSHARE_PROOF_SECRET, ZKSHARE_TEST_API_KEY

These are read from process.env at runtime. Make sure you trust where they’ll be sent.

// tools this server exposes6 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.

zkshare_store

Encrypt and store a fact (server-sealed). Same as REST operation store with value.

zkshare_prove

Produce a yes/no answer and signed proof envelope for a stored server-sealed fact.

zkshare_share

Like prove, plus issue a time-bound share token for a recipient agent id.

zkshare_search

Semantic search over stored server-sealed facts for this API key.

zkshare_sandbox

Run an allow-listed sandbox action (e.g. calculate_travel_budget, calculate_budget, analyze_spending).

zkshare_verify_proof

Verify a zkshare proof envelope (from prove/share) without reading fact plaintext.

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

6/6 tools missing one or more hints — zkshare_store (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); zkshare_prove (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); zkshare_share (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint), +3 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.

Tests exist

No test files found

Add tests that exercise each declared tool.

Production dependencies are patched

0 critical, 11 high severity in production deps — next@16.2.4 (high), next@16.2.4 (high)

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

Dev dependencies

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

Upgrade dev dependencies when convenient.

Claim the listing to review these findings one by one and send us a correction where you disagree, straight to the team. Claiming also means we tell you when the grade moves, and reach you first if we find anything urgent.

// 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 5 concrete improvements we can share with the publisher of this MCP. Each comes with specific guidance to raise the trust score.
