## Findings

No check matched anything in these tool definitions.


## Changes things (3)

Creates or changes something that can be changed back. Claude Code: ask.

### `missing_changes`

- 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:

```untrusted-server-text
For a whole project's outdated report — npm/pnpm outdated --json (current → from, wanted, latest), ncu --format installedVersion, pip or uv pip list --outdated --format json (version → from, latest_version → latest), go list -m -u -json all (Version → from, Update.Version → latest), cargo outdated, dotnet list package --outdated, a Gradle versions report — pass each package with the version installed and, where the tool gives them, wanted and latest.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.
```

### `upgrade_notes`

- 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:

```untrusted-server-text
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_new`

- 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:

```untrusted-server-text
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.
```

## Only reads (2)

Looks things up and changes nothing. Claude Code: allow.

### `list_products`

- The name "list_products" says "list": a word for reading.

Description, as the server wrote it:

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

### `search_releases`

- The name "search_releases" says "search": a word for reading.

Description, as the server wrote it:

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

## Claude Code permissions

For `.claude/settings.json`, assuming the server is installed as `changelogs`:

```json
{
  "permissions": {
    "allow": [
      "mcp__changelogs__list_products",
      "mcp__changelogs__search_releases"
    ],
    "ask": [
      "mcp__changelogs__whats_new",
      "mcp__changelogs__upgrade_notes",
      "mcp__changelogs__missing_changes"
    ],
    "deny": []
  }
}
