Context7 MCP Server

Context7 is a specialized MCP server designed to give your AI "super-memory" regarding your codebase. While standard AI tools index files, Context7 builds a semantic dependency graph specific to React Native and Expo patterns.

Features

• Semantic Search: Find components not just by name, but by logic (e.g., "Find the component that handles user logout").
• Dependency Graph: Understand the ripple effects of changes. "If I verify the AuthUser interface, what files will break?"
• Architecture Awareness: It understands Expo Router structure, Redux slices, and Tamagui/Gluestack styling patterns.

Installation & Configuration

Prerequisites

• A local React Native / Expo project.

Setup for Claude Code

{
  "mcpServers": {
    "context7": {
      "command": "npx",
      "args": ["-y", "context7-mcp"],
      "env": {
        "PROJECT_ROOT": "/absolute/path/to/your/project"
      }
    }
  }
}

Usage Examples

1. Impact Analysis:

"I'm planning to rename the User interface to AppUser. Use Context7 to find all files that will need to be updated."

2. Logical Search:

"Where is the code responsible for refreshing the auth token? I can't find it by filename."

3. Architectural Audit:

"Analyze my app directory structure. Are there any circular dependencies?"
