Codebase Understanding Plan

Project Overview

This is use-mcp, a TypeScript/React library that provides a lightweight React hook for connecting to Model Context Protocol (MCP) servers. It simplifies authentication and tool calling for AI systems implementing the MCP standard.

Repository Structure Analysis

Core Library (/src/)

  • Main exports: Core functionality and React hooks
  • React bindings: React-specific implementations
  • Authentication: OAuth and browser-based auth providers
  • Utilities: Helper functions and assertions

Examples (/examples/)

  • chat-ui/: Complete chat interface demonstration
  • inspector/: MCP server debugging and inspection tool
  • servers/: Example MCP server implementations

Testing (/test/)

  • Integration tests for MCP connections
  • Test utilities and configurations

Analysis Phases

Phase 1: Core Library Analysis

  1. ✅ Main entry point (src/index.ts)
  2. ✅ React hook implementation (src/react/)
  3. ✅ Authentication system (src/auth/)
  4. ✅ Utility functions (src/utils/)

Phase 2: Example Applications Analysis

  1. ✅ Chat UI application (examples/chat-ui/)
  2. ✅ Inspector tool (examples/inspector/)
  3. ✅ Server implementations (examples/servers/)

Phase 3: Configuration & Build Analysis

  1. ✅ Package configuration (package.json, tsconfig.json, etc.)
  2. ✅ Build system (tsup configuration)
  3. ✅ Development scripts and tooling

Phase 4: Testing Infrastructure

  1. ✅ Test setup and configuration
  2. ✅ Integration test implementations

Documentation Structure

Each component will be documented with:

  • Purpose: What the file/module does
  • Dependencies: What it imports and depends on
  • Exports: What it provides to other modules
  • Key Functions/Classes: Line-by-line analysis
  • Integration Points: How it connects to other parts
  • Configuration: Any configuration options or parameters

Todo Items for Analysis

  1. ✅ Analyze main library entry point
  2. ✅ Document React hook implementation
  3. ✅ Examine authentication providers
  4. ✅ Review utility functions
  5. ✅ Analyze chat-ui example application
  6. ✅ Document inspector tool
  7. ✅ Review MCP server examples
  8. ✅ Document build and configuration files
  9. ✅ Analyze test infrastructure
  10. ✅ Create comprehensive overview documentation
