The grade above is for the source repository. Registries can serve a different version, so we mark the ones we were not able to read.

// key findings
✅
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 1 credential: MOO_PASS
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.
configMOO_MCP_LOG
configMOO_USERWizard character name
🔐 secretMOO_PASSWizard password
configMOO_HOSTHostname or IP of the MOO admin port
configMOO_PORTTCP port (e.g. 7777, 3500)
configMOO_TIMEOUTSeconds to wait for a response (default 15)
configMOO_RECONNECTtrue/false, auto-reconnect on drop (default true)
configMOO_TLStrue/false, wrap the connection in TLS (default false). Use this when the MOO is fronted by stunnel or otherwise serves the admin port over TLS.
configMOO_TLS_INSECUREtrue/false, skip TLS certificate validation (default false). Only enable for self-signed certs on a MOO you control.

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

18/18 tools missing one or more hints — eval_moo (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); list_verb (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); program_verb (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint), +15 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

8/18 tools referenced in tests (44%)

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

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