What this server can do
7 functions, named and described by the server itself. Parameter names are shown because they say more about what a function does than its name usually does.
depwatch_preview(repo, since, package)- Free preview of breaking changes / new releases for a software dependency. Pass an npm/PyPI `package` (resolved and fetched live if not already tracked) or a GitHub `repo` (owner/repo). Returns up to 5 recent changes plus the package's current version. Full history, significance filtering, and the LLM brief are paid via x402.
list_feeds(compact, category)- 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.
packagehealth_preview(package, ecosystem)- FREE preview of a dependency's health: current version, deprecation flag, OpenSSF Scorecard, SPDX license, and known-advisory count (via deps.dev). The full ship/avoid verdict — per-advisory CISA-KEV active-exploit cross-reference, license-fit judgement, and LLM recommendation — is the paid /v1/packagehealth/check. Required: package.
preview_feed(repo, scope, since, source, package, ecosystem)- Free preview (up to 5 recent changes) for any feed. Pass the feed's `source` slug (from list_feeds). Optionally: `since` (ISO-8601) to window; `scope` to filter to an entity-id prefix on feeds that support it (e.g. an HTS code); or `package`/`repo`/`ecosystem` on feeds that resolve arbitrary entities live (e.g. dependency feeds). The full feed, status, and LLM brief are paid via x402. Required: source.
regwatch_preview(since)- Free preview of recent Federal Register regulatory actions in the tracked industry vertical. Returns up to 5 recent items. The full windowed feed and the LLM brief are paid via x402.
tariffwatch_preview(hts, since)- Free preview of recent US import-tariff changes. Optionally scope to an HTS code prefix (e.g. '6109' or '8471.30'). Returns up to 5 recent changes plus current duty-rate state for a scoped code. Full feed and the LLM brief are paid via x402.
vendorrisk_preview(name)- FREE preview of counterparty risk: tracked OFAC designations + product recalls we monitor for the name. The authoritative sanctions/denied-party (CSL) + federal debarment (SAM) screening and the CLEAR→PROHIBITED risk verdict are the paid /v1/vendorrisk/check. Required: name.

These are separate measurements of different things. They are deliberately not combined into one score, because a popularity number that mixes website traffic with saves and stars cannot be checked or acted on.
