Over the last week it answered 0.0% of our checks. We check every 15 minutes, so you hear about the next outage within the hour — not from your users.

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

missing

missing_changes

For a whole project's outdated report — npm/pnpm outdated --json (current → from, wanted, latest), ncu --format installedVersion, pip or uv pip list --outdated --format json (version → from, latest_version → latest), go list -m -u -json all (Version → from, Update.Version → latest), cargo outdated, dotnet list package --outdated, a Gradle versions report — pass each package with the version installed and, where the tool gives them, wanted and latest. Answers what the project is missing, most exposed first: per package, the security releases, CVE ids and fixes it does not have, split into toWanted (from → wanted: reachable by an update within the declared range, no manifest edit) and toLatest (→ latest: needs the range changed), with the cost of moving beside them (major bump, breaking mentions, removed/deprecated) and a few of the fixes themselves. Counts are deterministic over every tracked release; no model judged anything. Up to 100 packages a call. Pass repository (from the package's own package.json) for scoped or renamed packages; a Maven, Go or NuGet package goes by its purl. For the vendor's own breaking-change and migration sections, call upgrade_notes on the packages worth moving. A Maven, Go or NuGet package this server does not track is checked against deps.dev after the answer and counted; pass recordMisses: false for private packages.

products

list_products

The products What's New tracks release notes for, with slugs, categories and platforms. Filter by category and/or a name query.

releases

search_releases

Full-catalog search across product names and release history. Returns matching products and releases with permalinks.

upgrade

upgrade_notes

Before or after upgrading dependencies — package.json / lockfile / requirements changes, npm update, pip install -U, a Gradle version catalog, go.mod, a workflow's actions — pass each package with the version you run and the version you are moving to. Returns every tracked release in between with the vendor's own breaking-change, deprecation, migration and security sections verbatim, the categorized change list, CVE ids and deterministic signals (major bump, removed/deprecated items, breaking mentions) — including breaking changes shipped in minor or patch versions. Pass repository (from the package's own package.json) for scoped or renamed packages; it makes the match exact. A Maven/Gradle, Go, NuGet or GitHub Actions package goes by its purl (e.g. pkg:maven/com.squareup.okhttp3/okhttp), or by its own coordinate as the name (group:artifact, a module path, owner/repo@ref), and is matched exactly or not at all. A Maven, Go or NuGet package this server does not track is checked against deps.dev after the answer and counted, to decide what to track next; pass recordMisses: false for private packages.

whats

whats_new

A product's newest releases with notes. Pass since_version (the version you run) to get only what shipped after it, with per-category change counts.

What's New — questions

Answers built from our own checks of this server.

What can What's New do?

It exposes 5 tools, read directly from the server on our last check. Among them: list_products, missing_changes, search_releases, upgrade_notes, whats_new. 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 What's New working right now?

We send a real MCP handshake every 15 minutes. Over the last 24 hours 0 of 92 checks got a reply (0.0%), average response time 53 ms. The bar chart above shows every period we have measured.

The registry lists What's New as active — why does it not respond?

The official MCP registry stores what the author submitted; it does not verify that the server still runs. We check the endpoint ourselves, and this one does not answer. Catalogues that copy the registry without checking will show it as working.

How do I connect What's New?

Copy the ready config from this page. We generate it for Claude Code, Claude Desktop, Codex, Cursor and VS Code, each in the form that client actually reads. It is a remote server, so there is nothing to install — the client connects to the address.

Does What's New need an API key?

No. What's New completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 5 of them are readable on this page. This is what we observed, not what the docs claim.
