novyx-mcp@2.9.0

VERIFIED· not started

Publisher claims: "MCP tools for Novyx governed actions, shared memory, audit, rollback, and evidence workflows. Local SQLite memory works zero-config; hosted governance and approvals use Novyx Cloud." 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: Verified 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
NOVYX_API_KEYNOVYX_CONTROL_API_KEYConfiguration, not credentials: NOVYX_CONTROL_URL, NOVYX_DATA_DIR
Where it talks to
novyxlabs.com (its own)Also fly.dev — 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 fly.dev as well as its own vendor. The guard injects NOVYX_API_KEY, NOVYX_CONTROL_API_KEY only into requests to novyxlabs.com (and its subdomains) and refuses the rest.

$vet-skills run --secrets NOVYX_API_KEY=novyxlabs.com,NOVYX_CONTROL_API_KEY=novyxlabs.com -- uvx novyx-mcp

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 2026-11-13 and scored it 90/100 (Verified). In what ran, nothing we could detect went wrong: no undeclared network egress, no credential reads, no persistent instruction writes. What it does with a real credential was not observed; the static findings and the publisher carry the rest of the score. Summary: no network, touches nothing outside the project, writes no memory.
