# Is `npm:negotiator` safe to install? (snapshot)

**This page is a snapshot, not clearance, and not a safety guarantee.**
Advisories, registry data and KarmaDue answers change.
**Recheck live immediately before you install.** Do not treat `no_known_issues` or a missing record as approval.

## Recheck live before install

One-line MCP call:

    check {"target":"npm:negotiator","action":"install"}

curl:

```bash
curl -s -X POST https://ogogoizwsfaduzehkshb.supabase.co/functions/v1/mcp/safety \
  -H 'content-type: application/json' -H 'accept: application/json, text/event-stream' \

```

This snapshot was produced with the header `X-KD-Via: kd-founder-test` so KarmaDue can exclude founder test traffic from usage counts when that tagging is in place. You do not need that header.
