Documentation Lookup with Context7
Context7 provides up-to-date, version-specific documentation and code examples directly from source libraries.
Why Context7
- Current APIs: No hallucinated or outdated patterns
- Version-specific: Gets docs for exact library versions
- Code examples: Real, working code from actual documentation
Workflow
- Resolve library ID:
mcp__context7__resolve-library-idwithlibraryName - Get documentation:
mcp__context7__get-library-docswithcontext7CompatibleLibraryIDandtopic
Modes
| Mode | Use For |
|---|---|
code | API references, code examples (default) |
info | Conceptual guides, architecture, tutorials |
Examples
# React hooks
resolve-library-id: "react"
get-library-docs: context7CompatibleLibraryID="/facebook/react", topic="hooks", mode="code"
# Next.js middleware
resolve-library-id: "next.js"
get-library-docs: context7CompatibleLibraryID="/vercel/next.js", topic="middleware"
# Go net/http
resolve-library-id: "go net/http"
get-library-docs: context7CompatibleLibraryID="/golang/go", topic="http server"
# Kubernetes API
resolve-library-id: "kubernetes"
get-library-docs: context7CompatibleLibraryID="/kubernetes/kubernetes", topic="deployment"
Tips
- Use
topicparameter to narrow results to specific features - Try
mode="info"for architectural questions - Paginate with
page=2,page=3if initial results insufficient
Gotchas
- Context7 query without version scoping returns hits across versions — Next.js 14 question can answer with Next.js 12 code. Always include the version.
- Library aliases (e.g.,
reactvs@types/react) may resolve to different libraries — use the full Context7 ID, not the npm name. - Stale cache: Context7 may have indexed a library version that's been yanked from npm — check upstream before trusting.
- Rate limits per API key per day — bursting on the free tier locks the key out until midnight UTC.
- No multi-version diff: Context7 doesn't surface what changed between versions; for migrations, dual-query and compare manually.
