## Tools
- list_feeds (List all feeds) - 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. Endpoint: https://oracles-production.up.railway.app/mcp
- preview_feed (Preview any feed) - 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. Endpoint: https://oracles-production.up.railway.app/mcp
- packagehealth_preview (PackageHealth — free preview) - 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. Endpoint: https://oracles-production.up.railway.app/mcp
- vendorrisk_preview (VendorRisk — free preview) - 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. Endpoint: https://oracles-production.up.railway.app/mcp
- depwatch_preview (DepWatch — dependency change preview) - 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. Endpoint: https://oracles-production.up.railway.app/mcp
- regwatch_preview (RegWatch — regulatory change preview) - 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. Endpoint: https://oracles-production.up.railway.app/mcp
- tariffwatch_preview (TariffWatch — tariff/HTS change preview) - 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. Endpoint: https://oracles-production.up.railway.app/mcp
