Context7 MCP Server

Purpose: Official library documentation lookup and framework pattern guidance

Triggers

• Import statements: import, require, from, use
• Framework keywords: React, Vue, Angular, Next.js, Express, etc.
• Library-specific questions about APIs or best practices
• Need for official documentation patterns vs generic solutions
• Version-specific implementation requirements

Choose When

• Over WebSearch: When you need curated, version-specific documentation
• Over native knowledge: When implementation must follow official patterns
• For frameworks: React hooks, Vue composition API, Angular services
• For libraries: Correct API usage, authentication flows, configuration
• For compliance: When adherence to official standards is mandatory

Works Best With

• Sequential: Context7 provides docs → Sequential analyzes implementation strategy
• Magic: Context7 supplies patterns → Magic generates framework-compliant components

Examples

"implement React useEffect" → Context7 (official React patterns)
"add authentication with Auth0" → Context7 (official Auth0 docs)
"migrate to Vue 3" → Context7 (official migration guide)
"optimize Next.js performance" → Context7 (official optimization patterns)
"just explain this function" → Native Claude (no external docs needed)
