// key findings

✅

73 tools verified — handlers match their declared behaviour

28 read-only tools verified — handlers contain no write/delete/exec

✅

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: ANTHROPIC_API_KEY, DEEPSEEK_API_KEY, OPENAI_API_KEY, VOKO_MCP_TOKEN

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

Tool annotations

66/73 tools have annotations

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

All four hints declared on every tool

73/73 tools missing one or more hints — voko_a2a_discover_agent (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); voko_a2a_send_message (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); voko_a2a_get_task (missing: destructiveHint, idempotentHint, openWorldHint), +70 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 test coverage

Only 13/73 tools referenced in tests (18%)

Write tests that reference each tool by name so every tool has at least one test.

Dependency freshness

3/14 production deps abandoned (no release in 2+ years): curve25519-js@2022-04-28 (4.4y), md5-typescript@2023-01-02 (3.7y), json5@2023-03-04 (3.5y)

Domain consistency

npm scope @voko doesn't match GitHub owner laoyudashu

Use the same org name across GitHub, npm, and your homepage so users can verify the publisher.

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