mcpknight@0.1.0
CAUTION· not startedPublisher claims: "Active Runtime Security Firewall & Interceptor Gateway for Agent Tools & MCP Servers" Observed in sandbox: no network, touches nothing outside the project, writes no memory.
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
ANTHROPIC_API_KEYGEMINI_API_KEYGOOGLE_API_KEYGROQ_API_KEYOLLAMA_API_KEYOPENAI_API_KEYConfiguration, not credentials: ALMIGHT_DB_PATH, ALMIGHT_MODEL, ENVIRONMENT, INTENT_ANALYZER_MODEL, LOKI_URL, MCPSENTINEL_DB_PATH, MCPSENTINEL_LOG_DIR, MCPSENTINEL_LOG_LEVEL, MCPSENTINEL_LOKI_URL, MCPSENTINEL_MODEL, OLLAMA_HOST- Where it talks to
- no vendor host named in the codeAlso groq.com — 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 groq.com as well as its own vendor. The guard injects ANTHROPIC_API_KEY, GEMINI_API_KEY, GOOGLE_API_KEY, GROQ_API_KEY, OLLAMA_API_KEY, OPENAI_API_KEY only into requests to the host you bind (and its subdomains) and refuses the rest.

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 70/100 (Caution). It is not known to be malicious, but it has behaviour or code a security policy should decide on before install. Notable findings: Reads credential paths from the home directory; Access to sensitive file paths; Access to sensitive file paths. Summary: no network, touches nothing outside the project, writes no memory.
