# Project Summary: OpenAI WebSearch MCP Server (TypeScript)
## Quick Overview
A fully-functional TypeScript MCP server that adds web search capabilities to AI assistants like Claude using OpenAI's Web Search API with reasoning model support.
## Status: ✅ READY FOR TESTING
All implementation complete. Ready for end-to-end testing with MCP clients.
## Key Files
- `README.md` - User documentation and setup instructions
- `IMPLEMENTATION_PLAN.md` - Complete implementation details and future roadmap
- `src/index.ts` - MCP server entry point
- `.env.example` - Environment variable template
## Quick Start
```bash
# 1. Install Bun (if needed)
curl -fsSL https://bun.sh/install | bash
# 2. Install dependencies
bun install
# 3. Set up environment
cp .env.example .env
# Edit .env and add your OPENAI_API_KEY
# 4. Test with MCP Inspector
npx @modelcontextprotocol/inspector bun run src/index.ts
```
## What Works
✅ All core features implemented:
- Web search with reasoning models (gpt-5, gpt-5-mini, o3, etc.)
- Smart reasoning effort defaults
- Parameter validation
- Localized search support
- Comprehensive error handling
- Full TypeScript type safety
## Next Steps
1. Test with OpenAI API key
2. Integrate with Claude Desktop or Cursor
3. Verify all model types work correctly
4. Test edge cases and error scenarios
