Why it is in this group
- Nothing in its name or description says what it does, so it is counted as a write.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.
Description, as the server wrote it
For a whole project's outdated report — npm/pnpm outdated --json (current → from, wanted, latest), ncu --format installedVersion, pip or uv pip list --outdated --format json (version → from, latest_version → latest), go list -m -u -json all (Version → from, Update.Version → latest), cargo outdated, dotnet list package --outdated, a Gradle versions report — pass each package with the version installed and, where the tool gives them, wanted and latest.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.

Description, as the server wrote it
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.

Why it is in this group
- Nothing in its name or description says what it does, so it is counted as a write.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.
Description, as the server wrote it
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.

Why it is in this group
- The name "search_releases" says "search": a word for reading.
Description, as the server wrote it

This is not a safety rating, and no finding is not a safety guarantee. The groups and findings come from fixed checks of the tool definitions the server returned on the date shown, not from its code or what it does when called. How the checks work.

Anlyon alternative

3 of these tools change something. Run those as governed actions.

Declare what an action changes, and Anlyon puts it under a shared limit, binds every approval to the exact request, and grades the outcome. It works on any HTTPS API you can describe as an action.

Anlyon does not run, proxy or govern this MCP server. A tool your own code calls directly is not routed through Anlyon and is not governed by it.
