# SkyFi MCP - Diagnostic Report
## ✅ What I Found
### 1. **Environment Configuration**
- ✅ `.env` file exists
- ✅ PostgreSQL is running in Docker (port 5432)
- ✅ Configuration variables are set
### 2. **Current Configuration**
From your `.env` file:
- `SKYFI_DEMO_API_KEY` is set (the config supports this)
- `DATABASE_URL` is configured
- `JWT_SECRET` is set
- `API_KEY_ENCRYPTION_KEY` is set
- PostgreSQL is running and healthy
### 3. **Potential Issues**
#### Issue #1: API Key Variable Name
Your `.env` has `SKYFI_DEMO_API_KEY` but the config also checks for `SKYFI_API_KEY`.
**Status**: ✅ This should work - the config supports both names (see `src/config/index.ts` line 18-21)
#### Issue #2: Database May Not Be Initialized
Even though PostgreSQL is running, the database schema might not be created.
**Check**:
```bash
psql -h localhost -U postgres -d skyfi_mcp -c "\dt"
```
**Fix if needed**:
```bash
npm run db:setup
```
#### Issue #3: Port 3000 Might Be in Use
**Check**:
```bash
lsof -ti:3000
```
**Fix if needed**:
```bash
npm run kill:port
```
## 🔍 How to Diagnose Further
### Step 1: Check if Server Starts
```bash
npm run dev
```
Look for:
- ✅ "SkyFi MCP Server started" message
- ❌ Any error messages
### Step 2: Test Health Endpoint
```bash
curl http://localhost:3000/health
```
Expected response:
```json
{
"status": "healthy",
"timestamp": "...",
"service": "skyfi-mcp",
"version": "1.0.0"
}
```
### Step 3: Check Database Connection
```bash
psql -h localhost -U postgres -d skyfi_mcp -c "SELECT COUNT(*) FROM users;"
```
If this fails, the database isn't initialized.
### Step 4: Check Logs
When running `npm run dev`, check the console output for:
- Database connection warnings
- Port conflicts
- Missing environment variables
## 🎯 Most Likely Issues
Based on the codebase analysis:
### 1. **Database Not Initialized** (Most Common)
**Symptoms**: Server starts but database queries fail
**Fix**:
```bash
npm run db:setup
```
### 2. **Missing Dependencies**
**Symptoms**: Import errors or module not found
**Fix**:
```bash
npm install
```
### 3. **TypeScript Not Compiled**
**Symptoms**: Running `npm start` fails (production mode)
**Fix**:
```bash
npm run build
```
### 4. **Port Conflict**
**Symptoms**: "Port 3000 is already in use"
**Fix**:
```bash
npm run kill:port
```
## 📊 App Status Summary
### What Works ✅
- Server code is complete
- All routes are implemented
- Services are implemented
- Database schema is defined
- Tests are written (141+ tests)
- Docker setup is configured
### What Might Not Work ❌
- Database might not be initialized
- Dependencies might not be installed
- Port might be in use
- Environment variables might be missing (but yours look good)
## 🚀 Quick Fix Checklist
Run these commands in order:
```bash
# 1. Install dependencies
npm install
# 2. Setup database
npm run db:setup
# 3. Kill any process on port 3000
npm run kill:port
# 4. Start the server
npm run dev
```
## 📝 What This App Does (Simple Explanation)
1. **It's a REST API server** that runs on port 3000
2. **AI agents connect to it** to access SkyFi's geospatial data
3. **It translates requests** from AI agents into SkyFi API calls
4. **It stores data** in PostgreSQL
5. **It provides real-time updates** via Server-Sent Events
Think of it as a **translator/bridge** between AI systems and geospatial data services.
## 🔧 Architecture Flow
```
AI Agent Request
↓
HTTP POST to /v1/orders
↓
Authentication Middleware (checks API key)
↓
Order Service (business logic)
↓
SkyFi Client (calls external SkyFi API)
↓
Repository (saves to database)
↓
Response back to AI Agent
```
## 📚 Key Files
- **Entry Point**: `src/server/main.ts`
- **Config**: `src/config/index.ts`
- **Routes**: `src/server/routes/*.ts`
- **Services**: `src/services/*.ts`
- **Database**: `scripts/init-db.sql`
## 💡 Next Steps
1. **Try starting the server**: `npm run dev`
2. **Check the output** for any errors
3. **Test the health endpoint**: `curl http://localhost:3000/health`
4. **If it works**, generate an API key and test a search
