About Depsonar
Depsonar is an MCP server for developers maintaining projects across nine programming languages. It combines dependency updates with vulnerability and secret scans, migration checks, and audits of runtimes, toolchains, containers, and GitHub Actions.
Key features
- 01Manage dependencies across nine languages
- 02Preview updates and changelogs
- 03Scan CVEs and exposed secrets
- 04Detect migrations and deprecated packages
- 05Audit runtimes and development infrastructure
Use cases
- 01Review outdated dependencies across projects
- 02Check vulnerabilities before updating
- 03Find framework migration work
- 04Audit container images and GitHub Actions
MCP support
Depsonar exposes 23 dependency-management, security, migration, and infrastructure tools to MCP-compatible assistants such as Cursor and Claude.
Configuration
Local server config is the same for every client. Copy it into your client’s MCP config file.
We haven’t collected a package or remote endpoint for this server. Follow the instructions in the project README.
Tools
Local servers expose tools only once running on your machine, and the maintainer has not provided a tool list.
Details
From the project README
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.
- A lightweight script runs every N hours via macOS launchd or Linux cron
- Scans all projects, compares versions with registries
- Writes results to
~/.depsonar-cache.json, exits immediately - 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"

New to MCP?
From what the protocol is to installing your first server, these answers cover most first questions.
An open protocol that defines how AI applications connect to external tools and data in a uniform way. Clients talk to the model; MCP servers provide tools, resources and prompt templates. They exchange standard messages, so one server can be reused by many clients.
