Context7 Integration

Context7 is an MCP server that provides up-to-date documentation and code examples for programming libraries and frameworks.

When to Use Context7

Use Context7 when you need:

• Latest documentation for any programming library or framework
• Code examples and usage patterns
• API reference information
• Best practices for specific libraries

Before using Context7, you must:

1. Call context7_resolve-library-id to get the exact library ID
2. Then call context7_query-docs with that library ID

Required Workflow

Step 1: Resolve Library ID

Use context7_resolve-library-id first:

Copycontext7_resolve-library-id({
  libraryName: "react",
  query: "How do I use React hooks?"
})

This returns the exact Context7-compatible library ID (e.g., /vercel/next.js/v14.3.0-canary.87).

Only skip this step if the user explicitly provides a library ID in the format /org/project or /org/project/version.

Step 2: Query Documentation

Use context7_query-docs with the resolved library ID:

Copycontext7_query-docs({
  libraryId: "/vercel/next.js/v14.3.0-canary.87",
  query: "How to implement server-side rendering with next 14?"
})

Important Rules

• NEVER use context7_query-docs without first calling context7_resolve-library-id (unless user provides library ID)
• NEVER call these tools more than 3 times per question
• If you can't find what you need after 3 attempts, use the best information you have
• Don't include sensitive information (API keys, credentials, secrets) in queries
• Be specific and include relevant details in your query

Examples

Basic Example

Copy# User asks: "How do I use React Query?"

1. Call context7_resolve-library-id:
   - libraryName: "react-query"
   - query: "How do I use React Query?"

2. Get result: /tanstack/react-query

3. Call context7_query-docs:
   - libraryId: "/tanstack/react-query"
   - query: "How do I use React Query? Include setup examples and basic usage patterns"

Version-Specific Example

Copy# User asks: "What's new in Next.js 14?"

1. Call context7_resolve-library-id:
   - libraryName: "next.js"
   - query: "What's new in Next.js 14?"

2. Get result: /vercel/next.js/v14.3.0-canary.87

3. Call context7_query-docs:
   - libraryId: "/vercel/next.js/v14.3.0-canary.87"
   - query: "What's new in Next.js 14? List new features and breaking changes"

With User-Provided Library ID

Copy# User asks: "Show me examples of /mongodb/docs aggregation"

1. Skip resolve-library-id (user provided ID)
2. Call context7_query-docs directly:
   - libraryId: "/mongodb/docs"
   - query: "Show me aggregation pipeline examples"
