n1mem-mcp@0.6.1

VERIFIED· install only

Publisher claims: "N1Mem MCP server (BYOK, zero dependencies) — long-term memory for Claude / Cursor / OpenClaw, including one-call import of your existing agent memory and local value telemetry (~/.n1mem/events.jsonl)" Observed in sandbox: no network, touches nothing outside the project, writes no memory.

Coverage

Nothing executable in the bundle ran; the trace covers the install step only.
Tested
every file read, file written and host contacted by what ran
Not tested
use of the skill by an agent

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
N1MEM_API_KEYConfiguration, not credentials: N1MEM_AGENT_ID, N1MEM_BASE_URL, N1MEM_DEVICE_ID, N1MEM_HOME, N1MEM_INSTANCE, N1MEM_MCP_RETRIES, N1MEM_MCP_RETRY_BACKOFF, N1MEM_MCP_TIMEOUT, N1MEM_SUBJECT, N1MEM_TELEMETRY, N1MEM_TELEMETRY_MAX_MB, N1MEM_TELEMETRY_PREVIEW
Where it talks to
n1mem.com (its own)Also microsoft.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
use of the skill by an agent

Connect it with a scoped credential, under the guard, and read the third-party hosts first. The code names microsoft.com as well as its own vendor. The guard injects N1MEM_API_KEY only into requests to n1mem.com (and its subdomains) and refuses the rest.

$vet-skills run --secrets N1MEM_API_KEY=n1mem.com -- uvx n1mem-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 (1 scenario; nothing executable in the bundle ran; the trace covers the install step only) on 2026-11-13 and scored it 86/100 (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.
