Coverage

Not started: dependency install failed; the server itself was not observed.
Tested
the dependency install step · every file read, file written and host contacted by what ran
Not tested
server startup · the tool list · tool behavior

What this means for the label: Caution here covers what ran. The server's tools were not exercised with a real credential, so nothing about their behavior is asserted; the credential summary below says what to do with that.

Before you give it your token

It will ask for
MCP_JWT_SECRETMIN_JWT_SECRET_LENGTHMJ_API_KEYWEB_CLIENT_SECRETConfiguration, not credentials: DB_DATABASE, WEB_CLIENT_ID
Where it talks to
no vendor host named in the codeAlso microsoftonline.com, windows.net, evil.example — not the publisher's domain; check what for before connecting.
What the honeypot saw
no credential files read · no network
What we could not test
server startup · the tool list · tool behavior

Connect it with a scoped credential, under the guard, and read the third-party hosts first. The code names microsoftonline.com, windows.net, evil.example as well as its own vendor. The guard injects MCP_JWT_SECRET, MIN_JWT_SECRET_LENGTH, MJ_API_KEY, WEB_CLIENT_SECRET only into requests to the host you bind (and its subdomains) and refuses the rest.

Never paste a credential into a chat, a ticket or a report, including ours. How the guard holds it.

KillerSkills ran it in the KillerSkills honeypot sandbox (2 scenarios; not started: dependency install failed; the server itself was not observed) on 2026-11-11 and scored it 77/100 (Caution). It is not known to be malicious, but it has behaviour or code a security policy should decide on before install. Notable findings: Credential pass-through configuration; Access to sensitive file paths; Credential pass-through configuration. Summary: no network, touches nothing outside the project, writes no memory.
