For Cursor Users

Your Cursor AI Doesn't Know What Packages Actually Work

Cursor suggests packages from its training data, not from live registry data. PatternStack fixes this by watching 50,000+ packages across six registries for deprecations, breaking majors, and security issues.

The Problem with Cursor's Package Suggestions

Without PatternStack

✗Suggests moment.js (deprecated, 287kb)
✗Recommends request (deprecated since 2020)
✗Proposes incompatible version combinations
✗No awareness of CVEs or security issues

With PatternStack

Suggests date-fns (maintained, tree-shakeable)
Knows what Next.js 16 projects actually use
Validates version compatibility before suggesting
CVE and deprecation awareness

How PatternStack Works with Cursor

Install MCP Server

Add PatternStack to your Cursor config in 30 seconds. Works via the Model Context Protocol.

Code Normally

Ask Cursor about packages, dependencies, or migrations. It automatically queries PatternStack.

Responses now include real data from production projects, not just training data.

What PatternStack Gives Your Cursor

Live Package Intelligence

Live tracking of package status from OSV, GitHub Advisory, and Dependabot—detecting deprecations, maintenance mode, and breaking major releases.

Security Awareness

Vulnerability and deprecation context to help your AI avoid known-risk packages.

Framework Context

Warnings are partitioned by framework. Next.js projects get Next.js-specific deprecations and alternatives.

Package Patterns

See which packages are commonly used together in real projects, so you can make informed decisions about your stack.

Quick Start

# Add to your Cursor MCP config (~/.cursor/mcp.json)

      "headers": {
        "Authorization": "Bearer ts_your_api_key"
      }
    }
  }
