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.

Exfil surface

Which tools read private data, which read text someone else can write, and which can send data out. One of each is a path a prompt injection can use.

No private-data, untrusted-input, outbound path in this server alone: no tool is tagged private-data.

Reads private data0: Reads files, mail, messages, databases, secrets, calendars or repositories.
Reads text others write7: Brings in text someone else can write: web pages, inbound email, messages, issues and comments.; dependency_upgrade_plan
npm_breaking_changes
npm_changelog
npm_versions
pypi_breaking_changes
pypi_changelog
pypi_versions
Can send data out4: Can carry data to people or systems: it sends, posts or publishes, or takes a recipient, channel or URL.; npm_breaking_changes
npm_changelog
pypi_breaking_changes
pypi_changelog

Other servers in the same agent add their own tools to these paths. Audit your whole setup to see them together.

Install

Pinned to version 0.3.0. Values in angle brackets are yours to fill in.

claude mcp add --transport http upgrade-brief https://upgrade-brief.shopttyass-85f.workers.dev/mcp

Run in a terminal.

Claude Code permissions

Allow the reads, ask before a change or a way out, deny the deletes. Paste into .claude/settings.json.

.claude/settings.json

{
  "permissions": {
    "allow": [],
    "ask": [
      "mcp__upgrade-brief__npm_breaking_changes",
      "mcp__upgrade-brief__npm_changelog",
      "mcp__upgrade-brief__pypi_breaking_changes",
      "mcp__upgrade-brief__pypi_changelog",
      "mcp__upgrade-brief__dependency_upgrade_plan",
      "mcp__upgrade-brief__npm_versions",
      "mcp__upgrade-brief__pypi_versions"
    ],
    "deny": []
  }
}

Tools that only read are allowed, tools that change things ask first, tools that delete or cancel are denied. A read that can send data out (it takes a URL, say) asks first too. It assumes the server is installed as upgrade-brief. Review it before you use it.

Anlyon alternative

7 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.
