Coverage

Server started and answered tools/list.
Tested
MCP initialize and tools/list · every tool description, for hidden instructions · every file read, file written and host contacted by what ran
Not tested
what the tools do when called with real credentials

Before you give it your token

It will ask for
MANTIS_API_KEYConfiguration, not credentials: CACHE_ENABLED, CACHE_TTL_SECONDS, ENABLE_FILE_LOGGING, LOG_DIR, MANTIS_API_URL, MANTIS_FORCE_HTTPS
Where it talks to
no vendor host named in the codeAlso mantisbt.org — 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
what the tools do when called with real credentials

Connect it with a scoped credential, under the guard, and read the third-party hosts first. The code names mantisbt.org as well as its own vendor. The guard injects MANTIS_API_KEY 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) on 2026-11-09 and scored it 89/100 (Verified). It did what it claims and nothing else we could detect: no undeclared network egress, no credential reads, no persistent instruction writes. Summary: no network, touches nothing outside the project, writes no memory.
