Depsonar

The most complete dependency audit MCP server.
_{Scan · Audit · Update · Migrate — 9 languages, 23 tools, one MCP server}

  

depsonar is an MCP server that keeps your projects' dependencies up to date, scans for vulnerabilities, detects framework migrations, and audits your entire dev infrastructure — directly from Cursor, Claude, or any MCP-compatible AI assistant.

Supports Node.js, Python, Rust, Go, PHP, Ruby, Dart/Flutter, Swift, and Kotlin/Java.

Why depsonar?

With AI-generated "vibe coding" projects, dependency maintenance is an afterthought. WordPress solved this with one-click updates. depsonar brings the same experience to modern development — plus security scanning, migration detection, and infrastructure auditing.

Features

Dependency Management

• Multi-language: 9 languages, auto-detected
• Framework-aware: SvelteKit, Next.js, Nuxt, Astro, Django, Laravel, Express...
• Safe updates: 3 levels (patch/minor/latest) with dry-run preview
• Batch operations: Update all projects at once
• Ecosystem grouping: Results grouped by Svelte, Supabase, Tailwind, Vite, etc.

Security & Compliance

• Live CVE scanning via osv.dev API (npm, PyPI, crates.io, Go, PHP, Ruby)
• Framework CVE database: Curated advisories for Svelte, Next.js, Vite, Express, Axios
• Native audit integration: npm audit, cargo audit, pip-audit, composer audit, govulncheck
• Secret scanner: Detects AWS keys, GitHub tokens, Stripe keys, database URLs, and more
• License compliance: Flags GPL/AGPL copyleft, non-commercial, and unknown licenses

Migration & Maintenance

• Migration detector: Identifies code patterns that need changing (Svelte 4→5 runes, Next.js Pages→App Router)
• Changelog preview: See breaking changes before updating
• Deprecated detection: Finds unmaintained packages and suggests replacements
• Health scores: 0-100 per project based on deps, security, lockfile, runtime
• Background checker: Scheduled scans via macOS launchd or Linux cron

Infrastructure Audit

• Runtime versions: Node.js, Python, Rust, Go, PHP, Ruby, Dart, Swift (EOL detection)
• Global toolchain: npm, pnpm, yarn, bun, cargo, pip, git, docker, vercel, supabase, wrangler
• Docker image audit: Detects outdated/EOL base images
• GitHub Actions audit: Flags deprecated actions across all workflows
• Environment check: .env sync, lockfile freshness, config validation

Quick Start

Option 1: npx (zero install)

Add to ~/.cursor/mcp.json:

{
  "mcpServers": {
    "depsonar": {
      "command": "npx",
      "args": ["-y", "depsonar"]
    }
  }
}

Option 2: Global install

npm install -g depsonar

{
  "mcpServers": {
    "depsonar": {
      "command": "depsonar"
    }
  }
}

Option 3: Clone

git clone https://github.com/Soflution1/depsonar.git
cd depsonar && npm install && npm run build

{
  "mcpServers": {
    "depsonar": {
      "command": "node",
      "args": ["/path/to/depsonar/dist/index.js"]
    }
  }
}

Restart Cursor after editing the config.

Background Checker

The background checker scans your projects on a schedule and caches results. When you open Cursor, depsonar_alerts reads the cache instantly — zero wait.

1. A lightweight script runs every N hours via macOS launchd or Linux cron
2. Scans all projects, compares versions with registries
3. Writes results to ~/.depsonar-cache.json, exits immediately
4. Zero RAM between runs, zero AI tokens, zero cost

Setup from Cursor: "Setup background checking every 6 hours"

---

Configuration

Set your projects directory (auto-detected from ~/Cursor/App, ~/Projects, ~/Developer, ~/Code, ~/dev):

// ~/.depsonarrc.json
{
  "projectsDir": "/Users/me/my-projects"
}

Or from Cursor: "Set my projects directory to ~/Code"
