The Challenge

Business Problem

Outdated dependencies accumulate security vulnerabilities and technical debt. Teams defer updates because each one requires manual testing and risk assessment.

The Approach

Solution Overview

Connect GitHub MCP Server with npm/PyPI registries and CI pipelines to automatically detect outdated dependencies, create update PRs, and validate with automated tests.

Step-by-Step

Implementation Steps

Scan Dependencies

Check all project dependencies against the latest available versions.

Assess Risk

Categorize updates by risk: patch (low), minor (medium), major (high) based on semver.

Create Update PRs

Generate PRs for each update with changelog summaries and breaking change notes.

async function updateDependencies(repo) {
  const outdated = await detectOutdated(repo);
  for (const dep of outdated) {
    const branch = `deps/update-${dep.name}-${dep.latestVersion}`;
    await github.createBranch({ repo, branch });
    await updatePackageJson(repo, branch, dep);
    await github.createPullRequest({
      repo, head: branch, base: 'main',
      title: `Update ${dep.name} from ${dep.currentVersion} to ${dep.latestVersion}`,
      body: `## Changes\n${dep.changelog}\n\nRisk: ${dep.riskLevel}`
    });
  }
}

Auto-Merge Safe Updates

Auto-merge patch updates that pass all CI checks without human review.

Risk Assessor

function assessRisk(dep) {
  const [curMajor] = dep.currentVersion.split('.');
  const [newMajor] = dep.latestVersion.split('.');
  if (newMajor > curMajor) return 'high';
  if (dep.latestVersion.includes('beta')) return 'medium';
  return 'low';
}
