Available Tools

Tool	Description
resolve-library-id	Find the Context7 ID for a library (e.g., "react", "express")
get-library-docs	Fetch documentation and code examples for a resolved library

How It Works

1. You mention a library (e.g., "How do I use Zod schemas?")
2. Context7 resolves the library name to its documentation source
3. Current, version-specific docs and examples are fetched
4. Claude Code uses the real documentation to give accurate answers

Supported Libraries

Context7 indexes documentation for thousands of popular libraries including:

• Frontend: React, Vue, Svelte, Angular, Next.js, Nuxt, Astro
• Backend: Express, Fastify, Hono, NestJS, Django, Flask, FastAPI
• Databases: Prisma, Drizzle, TypeORM, Mongoose, SQLAlchemy
• Utilities: Zod, Lodash, date-fns, Axios, TanStack Query
• Infrastructure: Docker, Terraform, Kubernetes, AWS CDK
• Languages: TypeScript, Python, Rust, Go standard libraries

Setup

No API key needed. Simply add the configuration above and start using it. The server connects to Context7's hosted documentation service.

Usage Tips

• Mention specific library versions for version-targeted docs
• Works best when you name the library explicitly in your question
• Combine with other MCP servers for full-stack development workflows

Security Notes

• This is a read-only HTTP service - no local code execution
• Only documentation content is fetched; no code from your project is sent
• No authentication required means no credential management overhead
