You'll be asked for 8 credentials: ADMIN_PASSWORD, MCP_AUTH_TOKEN, SESSION_SECRET, SLIP_API_KEY, STRIPE_SECRET_KEY, STRIPE_WEBHOOK_SECRET, UEX_ACCESS_KEY, UEX_LICENSE_KEY
These are read from process.env at runtime. Make sure you trust where they’ll be sent.

// quality suggestions

All four hints declared on every tool

1/2 tools missing one or more hints — slip_checker_status (missing: destructiveHint, idempotentHint). 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

No license file

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

Secrets stay with their owner

1 secret sent to a request target we could not resolve (UEX_LICENSE_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.

Domain consistency

npm scope @workspace doesn't match GitHub owner overflowget

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

// 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.
