What you get
Package intelligence that lives inside your AI agents and workflows. No context switching. No dashboard tab-hopping.
Crowdsourced Recommendations
Ask "What do real Next.js projects use for auth?" and get adoption percentages from actual codebases — not opinions.
Security & Health Filtering
Vulnerable and deprecated packages are automatically filtered from recommendations. You see what is safe to ship.
AGI Safety Metadata
Every recommendation includes reasoning, confidence levels, and data sources. No black box — verify everything.
Framework-Aware Context
Recommendations are partitioned by framework. Next.js projects get Next.js patterns — not Django suggestions.
Real Adoption Data
See what percentage of similar projects use each package. Migration trends show when the ecosystem is moving.
Built for AI Agents
Ask your AI assistant anything — search packages, get alternatives, compare options, check security, analyze your stack.
Your AI is making package decisions. With outdated knowledge.
Without PatternStack
AI learned packages from 2+ years ago
- Recommends request (deprecated since 2020)
- Suggests packages with known CVEs
- No awareness of what real projects use
- Same suggestions for Next.js and Django
With PatternStack
Live data from 6,000+ real projects
- Filters deprecated packages automatically
- CVE blocking built into every recommendation
- Crowdsourced from real production codebases
- Framework-aware: Next.js gets Next.js patterns
One command connects your AI to live package intelligence — search, compare, check security, get recommendations.
Frequently Asked Questions
Common questions about MCP integration, pricing, and privacy.
npm outdated tells you your packages are up to date. Snyk tells you they're safe. PatternStack tells you if they're the right packages. You can be fully up to date on `request` (deprecated since 2020) — green checkmarks, bad architecture. Version checking and package selection are different problems.
npm trends shows download counts for individual packages. PatternStack shows what packages go together — "89% of projects using Prisma also use tRPC." Download counts don't tell you what works in combination with your framework.
Run `claude mcp add patternstack` in your terminal. That's it — your AI assistant now has access to all MCP tools for package intelligence.
We continuously sync 6,000+ real GitHub repositories across 11 ecosystems — npm, PyPI, crates, Go, and more. This is organic data from actual projects, updated hourly. No surveys, no opinions, no fabricated scores.
500 MCP requests per day, access to all MCP tools, CVE blocking, and framework-partitioned recommendations. Most individual developers never hit the limit.
Yes. MCP requests are authenticated, scoped to your account, and rate limited. We only access dependency metadata from your projects — never source code.
Any MCP-compatible agent: Claude Code, Cursor, Windsurf, and others. Install with one command and your AI assistant gets live package intelligence — search, compare, check security, get recommendations.
