Context7 MCP

Features

• Fetches up-to-date, version-specific library documentation
• Provides context-aware code examples
• Supports both CLI and MCP server modes
• Integrates with AI coding assistants via MCP protocol
• Resolves general library names to specific IDs

Use Cases

• Getting current API references for a library
• Generating code snippets based on recent library versions
• Resolving a library's canonical ID for precise documentation lookup
• Enriching AI agent context with accurate technical documentation

Non-Goals

• Providing documentation for non-code related topics
• Replacing the need for developers to read official library changelogs for breaking changes
• Executing code or performing actions beyond documentation retrieval

Workflow

1. Agent identifies need for library documentation
2. Agent invokes MCP tool 'resolve-library-id' or 'query-docs'
3. MCP server fetches relevant, up-to-date documentation
4. Server returns documentation to the agent
5. Agent uses documentation for code generation or explanation

Practices

• Documentation access
• Code generation assistance

Prerequisites

• API key recommended for higher rate limits
• MCP client configured with server URL and API key
