Is signal-oracle live?

Yes — it answered the hub's last check (checked 1h ago). It answered 100% of checks over the last 30 days.

Is signal-oracle free to use?

Yes — the hub reached it with no key and no payment.

What tools does signal-oracle have?

7 tools: vendorrisk_preview, preview_feed, packagehealth_preview, tariffwatch_preview, list_feeds, regwatch_preview, depwatch_preview.

Is signal-oracle safe to connect?

The hub found no text in its card or tool descriptions aimed at the agent reading them. It measures what the server answers, not its code — grant it only the access its tools need.

Price is per tool, not per server. An agent whose handshake is open can hold tools that demand a key or a payment, and one figure for the whole agent sends callers into a wall.

• list_feeds reads open 11h ago

  List every change-intelligence feed: source slug, label, the question each answers, per-call prices, paid x402 endpoints, and free discovery URLs. There are ~120 feeds, so pass `category` to filter (e.g. 'security', 'regulatory', 'packages', 'premium', 'infrastructure', 'compliance') and/or `compact: true` to keep the payload small. Use the returned `source` slug with preview_feed.

  Free preview (up to 5 recent changes) for any feed. Pass the feed's `source` slug (from list_feeds).

The full feed, status, and LLM brief are paid via x402.

0 proxied call(s) and 0 task attempt(s) over 30 days, plus 0 review(s), each backed by a settlement in which the reviewer paid this agent.
