Nothing serious here today

Today is the operative word: we check Dep Diff MCP every 15 minutes and re-read its code on every release. Watch it and you find out the day that stops being true.

analyze

analyze_package_change

Given one package and two versions (from -> to), returns a structured upgrade analysis: semver classification, GitHub release notes summary, detected breaking changes, security advisories fixed in the range, migration guide links, and a clear recommendation. Use when the user asks about a specific package upgrade ('what changed between react 18 and 19', 'is it safe to bump axios from 0.27 to 1.0', 'what does upgrading lodash 4.17.20 to 4.17.21 fix'). Supports npm, pypi, and github-actions (use the action reference as the name, e.g. actions/checkout). For analyzing many packages at once or a Dependabot batch, use analyze_packages_bulk instead.

analyze_packages_bulk

Analyzes a list of package upgrades in parallel and returns a unified risk report with packages ranked by recommendation level (security > caution > review > likely-safe > safe). Use when the user provides many dependency changes from a Dependabot PR, npm outdated output, lockfile diff, or batch upgrade. Returns: total count, breakdown by semver class, total security fixes found, packages with breaking changes, and per-package details. Limit 50 packages per call (chunk larger lists).

Dep Diff MCP — questions

Answers built from our own checks of this server.

What can Dep Diff MCP do?

It exposes 2 tools, read directly from the server on our last check. Among them: analyze_package_change, analyze_packages_bulk. 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 Dep Diff MCP 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 188 ms. The bar chart above shows every period we have measured.

How do I connect Dep Diff MCP?

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 Dep Diff MCP need an API key?

No. Dep Diff MCP completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 2 of them are readable on this page. This is what we observed, not what the docs claim.

How fast is Dep Diff MCP?

It answers our handshake in 188 ms on average, which is faster than 74% of all working MCP servers we measure. The comparison comes from our own checks across the whole registry, every 15 minutes.

How many people use Dep Diff MCP?

The npm package @digicatalyst/dep-diff-mcp was installed 113 times in the last week. Week over week that is +105%. We show installs rather than GitHub stars on purpose: a star is a bookmark, an install is someone actually running it.

Is Dep Diff MCP open source?

The code is open source: it is published under the MIT licence, written in TypeScript and 2 stars on GitHub. The licence covers the code in the repository, not the hosted service at dep-diff.digicatalyst.ca, which runs on its operator's own terms.
