What would fix thisWatchDispute verdict

Coverage

Startup only; authenticated tool behavior not tested.
Tested
server startup over stdio (initialize sent) · every file read, file written and host contacted by what ran
Not tested
the tool list (the server exited before answering) · what the tools do when called with real credentials

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
CORTEX_TOKENConfiguration, not credentials: AGNOCLAST_CLIENT, AGNOCLAST_TURN_CHECK, BUG_REPORTS_PATH, CLAUDE_CODE_SESSION_ID, CLAUDE_SESSION_ID, CLAUDECODE, CORTEX_AUTOFILE, CORTEX_CAPTURE_DETACHED, CORTEX_CAPTURE_SYNC, CORTEX_CLIENT_ROLE, CORTEX_HTTP_TIMEOUT_MS, CORTEX_REPORT_SPOOL_DIR, CORTEX_REVIEW_DISABLED, CORTEX_REVIEW_MODEL, CORTEX_SUMMARIZE_DISABLED, CORTEX_SUMMARIZING, CORTEX_SUMMARY_MODEL, CORTEX_SUMMARY_TIMEOUT_MS, CORTEX_SUMMARY_WINDOW, CORTEX_TYPED, CORTEX_URL, NEW_KEY, OLD_KEY
Where it talks to
no vendor host named in the codeAlso agnoclast.com, apple.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
the tool list (the server exited before answering) · 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 agnoclast.com, apple.com as well as its own vendor. The guard injects CORTEX_TOKEN only into requests to the host you bind (and its subdomains) and refuses the rest.

$vet-skills run --net declared -- npx -y @theronap/agnoclast-mcp

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

Is [email protected] safe to install?

KillerSkills ran it in the KillerSkills honeypot sandbox (2 scenarios; startup only; authenticated tool behavior not tested) on 2026-11-13 and scored it 69/100 (Caution). It is not known to be malicious, but it has behaviour or code a security policy should decide on before install. Notable findings: HTTP URL with a raw public IP address; Access to sensitive file paths; Access to sensitive file paths. Summary: no network, touches nothing outside the project, writes no memory.
