Available tools 7

Read directly from the server with tools/list, grouped by what they act on. If a tool disappears, we record the date.

depwatch
depwatch_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.
feeds
list_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.
packagehealth
packagehealth_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.
preview
preview_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.
regwatch
regwatch_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.
tariffwatch
tariffwatch_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.
vendorrisk
vendorrisk_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.

Signal Oracle — questions

Answers built from our own checks of this server.

What can Signal Oracle do?
It exposes 7 tools, read directly from the server on our last check. Among them: depwatch_preview, list_feeds, packagehealth_preview, preview_feed, regwatch_preview, tariffwatch_preview and 1 more. The full list with descriptions is on this page — we take it from the server itself via tools/list, not from a README. How MCP servers expose tools in the first place →
Is Signal Oracle working right now?
We send a real MCP handshake every 15 minutes. Over the last 24 hours 91 of 91 checks got a reply (100.0%), average response time 359 ms. The bar chart above shows every period we have measured.
Is Signal Oracle still maintained?
The linked repository no longer exists on GitHub — it was deleted or made private. We show this because it changes what you can expect: an unmaintained server may keep answering for months and then stop without warning.
How do I connect Signal Oracle?
Copy the ready config from this page — we generate it for Claude Code, Claude Desktop, Codex, Cursor and VS Code, each with the file path that client actually reads. It is a remote server, so there is nothing to install — the client connects to the address.
Does Signal Oracle need an API key?
No. Signal Oracle completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 7 of them are readable on this page. This is what we observed, not what the docs claim.
How fast is Signal Oracle?
It answers our handshake in 359 ms on average, which is faster than 39% of all working MCP servers we measure. The comparison comes from our own checks across the whole registry, every 15 minutes.
