## Dev Notes
### Files to Update
**Primary Documentation:**
- `README.md` - Main project documentation (multiple sections)
- `CLAUDE.md` - Claude Code integration guide
- `CHANGELOG.md` - Version history
**Examples Directory:**
- `examples/setup_with_claude.md`
- `examples/workflow_examples.md`
- `examples/complex_workflow.md`
- `examples/using_prompts.md`
**Other Documentation:**
- `docs/multi-instance-architecture.md` (check for URL examples)
### Current Incorrect Examples in README.md
**Lines to Fix:**
Line 80:
```json
"n8n_host": "https://n8n.example.com/api/v1/",
```
Line 84:
```json
"n8n_host": "https://staging-n8n.example.com/api/v1/",
```
Line 88:
```json
"n8n_host": "http://localhost:5678/api/v1/",
```
Lines 335, 348, 352 - Similar patterns in migration examples
### Correct Format Examples
**Multi-Instance Configuration (`.config.json`):**
```json
{
"environments": {
"production": {
"n8n_host": "https://n8n.example.com",
"n8n_api_key": "n8n_api_key_for_production"
},
"staging": {
"n8n_host": "https://staging-n8n.example.com",
"n8n_api_key": "n8n_api_key_for_staging"
},
"development": {
"n8n_host": "http://localhost:5678",
"n8n_api_key": "n8n_api_key_for_development"
}
},
"defaultEnv": "development"
}
```
**Single-Instance Configuration (`.env`):**
```env
N8N_HOST=https://your-n8n-instance.com
N8N_API_KEY=your_api_key_here
```
**n8n Cloud:**
```json
{
"n8n_host": "https://your-instance.app.n8n.cloud",
"n8n_api_key": "your_cloud_api_key"
}
```
### Configuration Best Practices Section
Add this new section to README.md after "Installation Guide":
````markdown
## Configuration Best Practices
### Correct URL Format
The n8n MCP server automatically appends `/api/v1` to your configured base URL. Always provide the **base URL without `/api/v1`**:
**✅ Correct Examples:**
```json
{
"n8n_host": "https://n8n.example.com",
"n8n_api_key": "your_api_key"
}
```
```json
{
"n8n_host": "http://localhost:5678",
"n8n_api_key": "your_api_key"
}
```
```json
{
"n8n_host": "https://your-instance.app.n8n.cloud",
"n8n_api_key": "your_api_key"
}
```
**❌ Incorrect Examples (will cause duplicate paths):**
```json
{
"n8n_host": "https://n8n.example.com/api/v1/", // ❌ Don't include /api/v1
"n8n_api_key": "your_api_key"
}
```
### Why This Matters
The server constructs the full API URL by appending `/api/v1` to your base URL:
```
Base URL: https://n8n.example.com
Final URL: https://n8n.example.com/api/v1/workflows ✅
Base URL: https://n8n.example.com/api/v1/
Final URL: https://n8n.example.com/api/v1/api/v1/workflows ❌
```
### Backward Compatibility
**Note for Existing Users:** If you have an existing configuration with `/api/v1` in the URL, it will continue to work. The server now automatically detects and removes duplicate `/api/v1` paths. However, we recommend updating to the correct format for clarity.
### Official n8n API Documentation
For more information about n8n API endpoints and URL structure, refer to:
- [n8n API Documentation](https://docs.n8n.io/api/)
- [n8n REST API Reference](https://docs.n8n.io/api/api-reference/)
````
### Migration Guide Section
Add this section to README.md:
````markdown
## Migrating from Old Configuration Format
If you have an existing configuration that includes `/api/v1` in the URL, you have two options:
### Option 1: Continue Using Current Configuration (Recommended for Quick Start)
Your existing configuration will continue to work due to backward compatibility:
```json
{
"n8n_host": "https://n8n.example.com/api/v1/", // Still works!
"n8n_api_key": "your_api_key"
}
```
The server automatically normalizes the URL internally.
### Option 2: Update to New Format (Recommended for Clarity)
Update your configuration to match the official n8n API documentation:
**Before:**
```json
{
"environments": {
"production": {
"n8n_host": "https://n8n.example.com/api/v1/",
"n8n_api_key": "your_api_key"
}
}
}
```
**After:**
```json
{
"environments": {
"production": {
"n8n_host": "https://n8n.example.com",
"n8n_api_key": "your_api_key"
}
}
}
```
**Steps:**
1. Open your `.config.json` or `.env` file
2. Remove `/api/v1` and any trailing slashes from `n8n_host` values
3. Save the file
4. Restart the MCP server
No code changes or additional configuration needed!
````
### Troubleshooting Section Addition
Add to existing Troubleshooting section in README.md:
````markdown
#### URL Configuration Issues
**Symptom:** API calls fail with 404 errors or "not found" messages
**Possible Cause:** Incorrect URL format causing duplicate `/api/v1` paths
**Solution:**
1. **Check your configuration file** (`.config.json` or `.env`)
Ensure your `n8n_host` does NOT include `/api/v1`:
```json
{
"n8n_host": "https://n8n.example.com" // ✅ Correct
}
```
NOT:
```json
{
"n8n_host": "https://n8n.example.com/api/v1/" // ❌ Will be auto-normalized
}
```
2. **Enable debug logging** to see URL construction:
```bash
DEBUG=true npm start
```
Look for lines like:
```
[EnvironmentManager] Original URL: https://n8n.example.com/api/v1/
[EnvironmentManager] Normalized baseURL: https://n8n.example.com/api/v1
```
3. **Verify n8n instance is accessible:**
```bash
curl https://your-n8n-host/api/v1/workflows \
-H "X-N8N-API-KEY: your_api_key"
```
4. **Check trailing slashes:**
Both of these are acceptable and will be normalized:
- `https://n8n.example.com` ✅
- `https://n8n.example.com/` ✅
````
### CHANGELOG.md Entry
Add this entry at the top of CHANGELOG.md:
````markdown
### 0.9.1

- 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"
**📚 Documentation:**
- **Configuration Best Practices** - Added comprehensive guide on correct URL format
- **Updated All Examples** - Corrected all configuration examples to match official n8n API documentation
- **Migration Guide** - Added guidance for users with existing configurations
- **Troubleshooting** - Enhanced troubleshooting section with URL configuration issues
- All examples now align with official n8n API documentation format
**✨ Features:**
- **Smart URL Detection** - Automatic normalization of user-provided URLs for maximum compatibility
- **Enhanced Debug Logging** - Shows both original and normalized URLs when `DEBUG=true`
**🔧 Technical Changes:**
- Updated `src/services/environmentManager.ts` to include URL normalization logic
- Added inline documentation explaining normalization process
- Improved error handling transparency
