// key findings
🚨
Secret credentials may flow to a network call
1 flow detected: SHIELD_API_KEY. We can’t prove the destination matches the brand the credential belongs to.
🔐
You'll be asked for 2 credentials: SHIELD_AGENT_KEY, SHIELD_API_KEY
These are read from process.env at runtime. Make sure you trust where they’ll be sent.
// environment variables
To run this server yourself, you supply these values. They go in your own MCP client configuration and stay on your machine. The secret label means the value is sensitive, not that the server mishandles it.
configAUTHZ_MODEeither put an auth gateway in front or set =off and let a policy
configDEFAULT_ROLE2. (Optional) Variables: AUTHZ_MODE (header default, or off), .
configDEFAULT_TENANT_IDTenant sent to Shield when the client does not send X-Tenant-ID
configSHIELD_AGENT_ID
🔐 secretSHIELD_AGENT_KEYAgent key/id sent to Shield tool guard endpoints
🔐 secretSHIELD_API_KEYTenant API key sent as X-API-Key
configSHIELD_BASE_URLShield API base URL, e.g. https://api.guardrails.votal.ai

configSHIELD_POST_CHECKSComma-separated endpoints called after tool execution
configSHIELD_PRE_CHECKSComma-separated endpoints called before tool execution

All four hints declared on every tool

12/12 tools missing one or more hints — search_flights (missing: idempotentHint, openWorldHint); search_hotels (missing: idempotentHint, openWorldHint); search_trains (missing: idempotentHint, openWorldHint), +9 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.

License file

Add a LICENSE file (MIT, Apache-2.0, etc.).

No test files found

Add tests that exercise each declared tool.

Secrets stay with their owner

1 secret sent to a request target we could not resolve (SHIELD_API_KEY → dynamic) — often a configured endpoint, not necessarily third-party

Audit where credentials are sent. A NOTION_TOKEN should only reach api.notion.com — never a third-party host.

// 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.
