Analyze npm/pypi package upgrades for breaking changes, security fixes, and migration risk via @digicatalyst/dep-diff-mcp (npx)

intentgiven a package name and version range, fetch release notes, detect breaking changes, list security advisories fixed, and produce a risk-ranked recommendation (safe / likely-safe / caution / security) — supports npm and pypi, single or bulk analysisconstraints

Looking for an MCP server that analyzes dependency upgrades before committing to them. Given a package name (npm or pypi), fromVersion and toVersion, it should fetch GitHub release notes, extract breaking changes, check for security advisories fixed in the range, and produce a structured recommendation. Bulk mode for Dependabot-style batch upgrades.

@digicatalyst/dep-diff-mcp v latest — Dependency upgrade analysis via MCP

Install: npm install @digicatalyst/dep-diff-mcp Entry: dist/server.js (stdio transport) Tools: 2 — analyze_package_change, analyze_packages_bulk

Tool schemas

  1. `analyze_package_change` ({ecosystem: "npm"|"pypi", name: string, fromVersion: string, toVersion: string}) → returns structured analysis: {package, ecosystem, fromVersion, toVersion, semverClass, repoUrl, releaseCount, breakingChanges[], securityFixes[], migrationLinks[], recommendation, recommendationLevel}. Recommendation levels: "safe" / "likely-safe" / "review" / "caution" / "security".
  1. `analyze_packages_bulk` ({changes: [{ecosystem, name, fromVersion, toVersion}]}) → batch analysis (max 50 packages). Returns {totalPackages, bySemverClass: {major, minor, patch}, securityFixesTotal, packagesWithBreakingChanges, packages: [...per-package details...]}.

Test results — 6 calls, 100% success (5 OK + 1 correct rejection)

CallResultms
lodash 4.17.20→4.17.21 (patch)semverClass: "patch", 2 security fixes (ReDoS + Command Injection), level: "security"2023
axios 0.27.2→1.7.9 (major)57 releases, breakingChanges extracted, 1 security fix (CSRF), level: "security"1287
react 18.2.0→19.0.0 (major)Extensive breaking changes (propTypes removed, defaultProps removed, string refs removed, etc.), 2 migration links to react.dev, level: "caution"1847
requests (pypi) 2.28.0→2.32.3 (minor)3 security fixes (verify=False leak, Proxy-Auth leak), release excerpts included, level: "security"591
bulk: express+typescript+eslint3 packages analyzed in parallel, 2 security fixes total, express+eslint flagged for breaking changes, typescript "likely-safe"2296
nonexistent packageGraceful text error: "npm registry returned 404"265

p50 latency: 1287ms (network-bound — fetches from GitHub API, npm/pypi registries)

Key gotchas

  1. No GITHUB_TOKEN required — works anonymously but rate-limited to 60 requests/hour. Warns at startup: "No GITHUB_TOKEN set and gh CLI unavailable. Running anonymous (60 req/hr)." For heavy use, set GITHUB_TOKEN env var.
  2. PyPI support works — ecosystem: "pypi" correctly fetches from PyPI and cross-references GitHub security advisories.
  3. ⚠️ "breakingChanges" are extracted from release note sections/bullets — not always accurate. Express 4.18.3→4.20.0 lists "removed unused originalIndex" as a breaking change — that's an internal refactor, not an API break. Treat these as hints requiring human review.
  4. `releaseExcerpts` only appear for minor/patch upgrades — major versions show breakingChanges array instead.
  5. Migration links only for well-known packages — React has react.dev/blog/... links, most packages return empty migrationLinks[].
  6. Nonexistent packages handled as text (not MCP error) — returns "Failed to analyze: npm registry returned 404". No crash.
  7. Batch limit: 50 packages per call — chunk larger Dependabot PRs.
  8. Security advisory data comes from GitHub Advisory Database — includes GHSA IDs and severity (LOW/MODERATE/HIGH/CRITICAL).
  9. Network-bound latency — 265ms–2296ms depending on how many releases need fetching. React with 3 releases = 1847ms, TypeScript with 18 releases is fetched in batch = faster per-package.
  10. `semverClass` uses 0.x→1.x correctly as "major" even though semver technically considers 0.x as unstable.
