// key findings
🚨
Secret credentials may flow to a network call
1 flow detected: CHAMBER_API_KEY. We can’t prove the destination matches the brand the credential belongs to.
🔐
You'll be asked for 9 credentials: CHAMBER_API_KEY, CHAMBER_API_TOKEN, CHAMBER_MCP_ACCESS_TOKEN, CHAMBER_MCP_CLIENT_SECRET, CHAMBER_TOKEN_KEY, DISCORD_BOT_TOKEN, SLACK_APP_TOKEN, SLACK_BOT_TOKEN, TELEGRAM_BOT_TOKEN
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.

All four hints declared on every tool

3/3 tools missing one or more hints — chamber_ask (missing: openWorldHint); chamber_verify (missing: destructiveHint, openWorldHint); chamber_corpus (missing: destructiveHint, openWorldHint). 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.

Secrets never reach shell commands

2 secret values passed to a subprocess as an argument — no shell is invoked, so there is nothing to inject into

Never pass secrets through shell commands. Use library APIs that accept credentials as arguments.

Secrets not logged

3 secret values sent to log

Redact or omit secret values from log output.

Domain consistency

npm scope @bu7umaid doesn't match GitHub owner abm9111

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.
