About this tool
Context7
Context7 is a lightweight, modular MCP-compatible memory and agent protocol server focused on privacy-first, on-device AI agents. It provides up-to-date, version-specific documentation and code examples directly into AI coding assistants and LLM prompts, helping developers avoid outdated or hallucinated APIs and reducing errors in code generation.
Features
- MCP-Compatible Server: Implements the Model Context Protocol (MCP), enabling seamless integration with various AI coding assistants and LLMs.
- Privacy-First, On-Device AI: Designed to run locally, ensuring user privacy and control over data.
- Supports Local and Cloud LLMs: Can be used with both local and cloud-based large language models.
- Persistent, Session-Aware Memory: Maintains session context and persistent memory for enhanced agent interactions.
- Up-to-Date Documentation: Fetches real-time, version-specific documentation and code examples from source repositories.
- Context Injection: Integrates documentation and examples directly into your prompt context for LLMs and coding assistants like Cursor, Windsurf, Claude Desktop, VS Code, Zed, and more.
- No Tab Switching: Eliminates the need to switch tabs or search for docs manually.
- Multiple Installation Methods: Can be installed via Node.js (npx, bun, deno), Docker, and through integrations in various editors and environments.
- Available Tools: Provides utilities like
resolve-library-id(to resolve general library names) andget-library-docs(fetch documentation by library ID, with topic/tokens options). - Open Source: Licensed under MIT, with active development and community contributions.
- Multilingual Documentation: Docs available in multiple languages (English, Chinese, Korean, Spanish, French, Portuguese, Italian, Indonesian, German).
