Context7

Context7 Documentation Lookup

Retrieves official documentation for libraries and frameworks.

Workflow

1. Resolve Library ID (Required)

mcp__context7__resolve-library-id
libraryName: "react" or "vue" or "express"

2. Fetch Documentation

mcp__context7__get-library-docs
context7CompatibleLibraryID: "/vuejs/core"
topic: "composition-api"     # Optional: specific topic
mode: "code"                 # "code" or "info"
page: 1                      # Paginate if needed

Mode Selection

code (default): API references, code examples, implementation patterns

info: Conceptual guides, architecture explanations

Tips

• Always resolve library ID first (don't guess ID format)
• Use page: 2, 3... if initial results insufficient
• Try alternative library names if no results (e.g., "vue router" vs "vue-router")
• Version-specific IDs: /org/project/v3

When to Use

• Library API specification lookup
• Official best practices
• Framework-specific implementation patterns
• Code examples and samples
