Real-time fetching of latest official documentation Precise querying by library name and topic Automatic context injection into conversations

Detailed Description

Context7 solves the most common pain point of AI coding assistants — using outdated APIs and non-existent functions. It can fetch the latest official documentation of any open-source library in real-time and inject accurate code examples and API descriptions into the AI conversation context.

Core Features

  • Library Search (resolve_library_id): Fuzzy search by library name, returning a list of matching libraries with their Context7 IDs to precisely locate target documentation
  • Documentation Retrieval (get_library_docs): Fetch the latest documentation content for a specified library, with support for filtering by topic and controlling the number of returned tokens
  • Version Awareness: Always returns the latest version of documentation, avoiding the outdated API issues found in AI training data
  • Code Examples: Returned documentation includes ready-to-use code examples, ensuring the correctness of generated code

Configuration

{
  "mcpServers": {
    "context7": {
      "command": "npx",
      "args": ["-y", "@context7/mcp"]
      // No API Key required, free to use
    }
  }
}

Use Cases

  • Developing with new frameworks: Ensure AI-generated Next.js/Svelte/Vue code uses the latest APIs
  • Library version upgrades: View new version Breaking Changes and migration guides
  • API reference lookup: Quickly get parameter, return value, and usage examples for a function
  • Learning new technologies: Get authoritative official documentation rather than outdated blog content
