# MCP PostgreSQL Server Setup Progress
## Project Overview
Building an MCP server that connects to PostgreSQL database with authentication for Claude web interface.
## Research Completed ✅
1. **Existing MCP PostgreSQL Solutions**: Found official TypeScript PostgreSQL MCP server, Postgres MCP Pro, Azure version
2. **Authentication Requirements**: Claude web interface requires OAuth 2.1 (March 2025 spec), needs Pro/Max/Team/Enterprise plans
3. **Language Ecosystem**: TypeScript has slight advantages with better tooling, OAuth support, templates
4. **Decision**: Using official TypeScript PostgreSQL MCP server as base
## Files Created ✅
- `package.json` - Node.js project with MCP dependencies
- `tsconfig.json` - TypeScript configuration
- `docker-compose.yml` - PostgreSQL container setup
- `init.sql` - Sample database with users, products, orders tables
- `.env.example` - Environment variable template
- `src/` directory created
- Dependencies installed with `npm install`
## Implementation Status ✅
1. **PostgreSQL Container**: `docker-compose up -d` ✅
2. **Source Files Created**: ✅
- `src/index.ts` - Main MCP server with PostgreSQL integration
- `src/auth.ts` - Authentication middleware (JWT + API key)
- `src/config.ts` - Configuration management with Zod validation
3. **Database Connection**: PostgreSQL container running and connected ✅
4. **MCP Server**: Basic functionality working (resources, tools) ✅
## Current Implementation Status
- ✅ Research and planning completed
- ✅ Project structure and dependencies set up
- ✅ Docker PostgreSQL container running
- ✅ Source code implementation (MCP server with PostgreSQL)
- ✅ Authentication configuration (OAuth 2.1 + API key server)
- 🔄 Claude integration testing (manual testing needed)
## Current Commands
```bash
cd /home/kevin/proj/volition/claude/mcp-server
docker-compose up -d # Start PostgreSQL (already running)
npm run dev # Start MCP server (stdio mode)
npm run dev:github # Start GitHub OAuth server (HTTP mode)
npm run build # Build TypeScript
```
## Server Status
- **Database**: PostgreSQL running on localhost:5432
- **MCP Server**: Ready to accept connections via stdio
- **OAuth Server**: HTTP server with OAuth 2.1 + API key auth
- **Sample Data**: Users, products, orders tables populated
- **Available Tools**: `query`, `describe_table`
- **Resources**: All tables accessible via `postgres://table/{name}`
## Files Created
- `src/index.ts` - Main MCP server (stdio transport)
- `src/github-oauth-server.ts` - GitHub OAuth integration server
- `src/auth.ts` - JWT + API key authentication middleware
- `src/config.ts` - Configuration with environment validation
- `.env` - Environment variables (DB + auth config)
- `GITHUB_OAUTH_SETUP.md` - Step-by-step GitHub OAuth setup guide
## Key Insights
- Official MCP PostgreSQL server is read-only, we'll extend it for auth
- Claude web interface needs specific OAuth 2.1 implementation
- TypeScript ecosystem more mature than Python for MCP
- Project structure follows Node.js/MCP best practices
