---

### Phase 3: Manual Testing with Real n8n Instance (Recommended)

**Duration:** 10-15 minutes
**Prerequisites:** Access to n8n instance with API key

#### Test Scenario 1: Base URL without /api/v1

**Configuration (.env):**
```
N8N_HOST=https://your-n8n-instance.com
N8N_API_KEY=your_actual_api_key
DEBUG=true
```

**Test:**
```bash
DEBUG=true npm start
```

**Expected Debug Output:**
```
[EnvironmentManager] Original URL: https://your-n8n-instance.com
[EnvironmentManager] Normalized baseURL: https://your-n8n-instance.com/api/v1
```

**API Test:**
Use MCP tools to list workflows or create a test workflow.

**Pass Criteria:**
- ✅ Server starts without errors
- ✅ Debug logging shows correct normalization
- ✅ API calls succeed (workflows listed, created, etc.)
- ✅ No 404 errors or duplicate /api/v1 paths

---

#### Test Scenario 2: Base URL with /api/v1 (Backward Compatibility)

**Configuration (.env):**
```
N8N_HOST=https://your-n8n-instance.com/api/v1/
N8N_API_KEY=your_actual_api_key
DEBUG=true
```

**Test:**
```bash
DEBUG=true npm start
```

**Expected Debug Output:**
```
[EnvironmentManager] Original URL: https://your-n8n-instance.com/api/v1/
[EnvironmentManager] Normalized baseURL: https://your-n8n-instance.com/api/v1
```

**Pass Criteria:**
- ✅ Server starts without errors
- ✅ Debug logging shows normalization removed duplicate /api/v1
- ✅ API calls succeed
- ✅ Backward compatibility confirmed

---

#### Test Scenario 3: Multi-Instance Configuration

**Configuration (.config.json):**
```json
{
  "environments": {
    "production": {
      "n8n_host": "https://n8n-prod.example.com",
      "n8n_api_key": "prod_key"
    },
    "staging": {
      "n8n_host": "https://n8n-staging.example.com/api/v1/",
      "n8n_api_key": "staging_key"
    }
  },
  "defaultEnv": "production"
}
```

**Test:**
```bash
DEBUG=true npm start
```

**Expected:**
- Both environments normalized correctly
- Can switch between instances
- API calls work for both environments

**Pass Criteria:**
- ✅ Multi-instance routing works
- ✅ Both URL formats normalized correctly
- ✅ Singleton caching works per environment

---

#### Test Scenario 4: Debug Logging Verification

**Test:**
```bash
# Without DEBUG
npm start
# Should see NO [EnvironmentManager] logs

# With DEBUG
DEBUG=true npm start
# Should see [EnvironmentManager] logs
```

**Pass Criteria:**
- ✅ Debug logging only active when DEBUG=true
- ✅ Logs show original and normalized URLs
- ✅ No sensitive information (full API keys) in logs
- ✅ Logs use console.error (not stdout)

---

### Phase 4: Integration Testing (Recommended)

**Duration:** 10-15 minutes

#### Test 1: Workflow Creation with New URL Format
```bash
# Create test workflow using MCP tools
# Verify workflow created successfully
# Verify workflow can be activated
# Verify workflow can be executed (if has valid trigger)
```

#### Test 2: Execution Tracking
```bash
# List executions
# Get execution details
# Verify data retrieval works
```

#### Test 3: Tag Management
```bash
# Create tag
# Update tag
# Get tags
# Delete tag
```

#### Test 4: Multi-Instance Operations
```bash
# Switch between instances
# Verify cache is working (no repeated config loads)
# Confirm instance isolation
```

**Pass Criteria:**
- ✅ All 14 MCP tools work correctly
- ✅ No regression in existing functionality
- ✅ Multi-instance routing works
- ✅ Caching reduces API calls

---

### Phase 5: Regression Testing (Critical)

**Duration:** 15-20 minutes

#### Run Existing Test Scripts
```bash
# Run comprehensive MCP tools test
node test-mcp-tools.js

# Expected: All tests pass with new URL normalization
```

**Test Coverage:**
- Workflow CRUD operations
- Tag management
- Execution tracking
- Multi-instance support

**Pass Criteria:**
- ✅ No test failures
- ✅ No new errors introduced
- ✅ All existing functionality preserved

```markdown
## 🐛 Bug Fixes

**URL Configuration Normalization** - Fixed URL path duplication issue where user configurations containing `/api/v1` resulted in duplicate path segments (`/api/v1/api/v1/`)
- Server now intelligently detects and normalizes URLs regardless of format
- Maintains full backward compatibility with existing configurations
- Thanks to user bug report: "The Host URL should not be appended with /api/v1 as the URL Builder will append that automatically"

**Singleton Caching Pattern** - Optimized EnvironmentManager to check cache before config loading for improved performance

## ✨ Features

- **Smart URL Detection** - Automatic normalization of user-provided URLs for maximum compatibility
  - 3-step normalization process
  - Handles all edge cases: base URLs, trailing slashes, localhost, n8n Cloud URLs
- **Enhanced Debug Logging** - Shows both original and normalized URLs when `DEBUG=true`

## 📚 Documentation

- **Configuration Best Practices** - Comprehensive guide on correct URL format
- **Migration Guide** - Added guidance for users migrating from old URL configuration format
- **Troubleshooting** - Enhanced troubleshooting section with URL configuration issues
- **Updated All Examples** - All configuration examples now match official n8n API documentation

## 🔧 Technical Changes

- Updated `src/services/environmentManager.ts` with URL normalization logic
- Added inline documentation explaining normalization process
- Improved error handling transparency
- Added comprehensive unit test suite (22+ test cases)
- Jest testing infrastructure with ts-jest
- 80% code coverage threshold
