## Usage
### Claude Desktop Configuration
Add the MCP to Claude Desktop configuration:
- On MacOS: `~/Library/Application Support/Claude/claude_desktop_config.json`
- On Windows: `%APPDATA%/Claude/claude_desktop_config.json`
Add the following configuration:
```json
{
"mcpServers": {
"rohlik": {
"command": "npx",
"args": ["-y", "@tomaspavlin/rohlik-mcp"],
"env": {
"ROHLIK_USERNAME": "your-email@example.com",
"ROHLIK_PASSWORD": "your-password",
"ROHLIK_BASE_URL": "https://www.rohlik.cz"
}
}
}
}
```
### Supported Regions
The server supports multiple Rohlik regions by setting the `ROHLIK_BASE_URL` environment variable:
* **Czech Republic**: `https://www.rohlik.cz` (default)
* **Germany**: `https://www.knuspr.de`
* **Austria**: `https://www.gurkerl.at`
* **Hungary**: `https://www.kifli.hu`
* **Romania**: `https://www.sezamo.ro`
* **Italy** (planned): `https://www.sezamo.it`
* **Spain** (planned): `https://www.sezamo.es`
If `ROHLIK_BASE_URL` is not specified, it defaults to the Czech version.

See [tests/README.md](./tests/README.md) for detailed testing documentation.
### Testing with Claude Desktop
Add this to configuration:
```json
{
"mcpServers": {
"rohlik-local": {
"command": "node",
"args": ["/path/to/rohlik-mcp/dist/index.js"],
"env": {
"ROHLIK_USERNAME": "your-email@example.com",
"ROHLIK_PASSWORD": "your-password",
"ROHLIK_BASE_URL": "https://www.rohlik.cz"
}
}
}
}
```
### Debug Mode
If you're experiencing authentication issues, enable debug mode to see detailed logs:
```json
{
"mcpServers": {
"rohlik-local": {
"command": "node",
"args": ["/path/to/rohlik-mcp/dist/index.js"],
"env": {
"ROHLIK_USERNAME": "your-email@example.com",
"ROHLIK_PASSWORD": "your-password",
"ROHLIK_BASE_URL": "https://www.rohlik.cz",
"ROHLIK_DEBUG": "true"
}
}
}
}
```
Debug logs will appear in `~/Library/Logs/Claude/mcp-server-rohlik-local.log` (macOS) or `%APPDATA%/Claude/logs/mcp-server-rohlik-local.log` (Windows).
### Testing with MCP Inspector
You can test the MCP server using the official MCP Inspector (https://modelcontextprotocol.io/legacy/tools/inspector):
```bash
npm run inspect
```
In the Inspector, set the ROHLIK_USERNAME and ROHLIK_PASSWORD envs.
### API Validation Tool
To validate that all Rohlik API endpoints are working correctly and diagnose authentication issues:
```bash
npm run validate-api
```
This will:
- Test all 11 API endpoints used by the MCP server
- Show detailed HTTP request/response logs in the console
- Generate a JSON report: `tests/validation-results.json`
- Generate a beautiful HTML report: `tests/validation-report.html`
The validator automatically loads credentials from your Claude Desktop config or environment variables. Open the HTML report in your browser for an easy-to-read summary of all tests.
## Troubleshooting
### Common Issues
#### Claude Desktop does not see the MCP server (on Windows)
For your config file, instead of `%APPDATA%/Claude/claude_desktop_config.json` use `C:\Users\[YOUR WINDOWS USER]\AppData\Local\Packages\Claude_pzs8sxrjxfjjc\LocalCache\Roaming\Claude\claude_desktop_config.json`
#### "Login failed" Error
**Possible causes:**
1. Wrong username/password in configuration
2. Rohlik API changed or is temporarily unavailable
3. Network connectivity issues
**Solutions:**
1. Verify credentials in your `claude_desktop_config.json`
2. Enable debug mode: `"ROHLIK_DEBUG": "true"` in env section
3. Check logs: `~/Library/Logs/Claude/mcp-server-rohlik*.log` (macOS) or `%APPDATA%\Claude\logs\mcp-server-rohlik*.log` (Windows)
4. Run API validator: `npm run validate-api` to test all endpoints
#### "No order history found"
**Cause:** Your account has no past orders, or orders are not accessible
**Solution:** Ensure you have at least one completed order on Rohlik before using smart shopping features (`get_meal_suggestions`, `get_frequent_items`)
#### Slow response times
**Causes:**
- Analyzing too many orders (smart shopping features)
- Network latency to Rohlik servers
- API rate limiting
**Solutions:**
- For smart shopping: reduce number of orders analyzed (try 10 instead of default 20)
- Use fewer requests or add delays between bulk operations
- Check your network connection
#### Products not found or search returns no results
**Causes:**
- Product out of stock or discontinued
- Product ID changed in Rohlik system
- Spelling mistake in search query
**Solutions:**
- Search by partial name instead of full product name
- Try alternative spellings or broader search terms
- Verify product exists on Rohlik website directly
#### Server fails with `spawn npx ENOENT`
Under Claude Desktop, fails with:
```shell
spawn npx ENOENT
Server disconnected. Transport closed unexpectedly.
```
**Solutions:**
- Change config to use absolute path to npx as /Users/adam/.local/share/mise/installs/node/22.14.0/bin/npx)
- See more info: https://github.com/tomaspavlin/rohlik-mcp/issues/6
### Enabling Debug Mode
Add `ROHLIK_DEBUG` to your configuration to see detailed logs:
```json
{
"mcpServers": {
"rohlik-local": {
"command": "node",
"args": ["/path/to/rohlik-mcp/dist/index.js"],
"env": {
"ROHLIK_USERNAME": "your-email@example.com",
"ROHLIK_PASSWORD": "your-password",
"ROHLIK_BASE_URL": "https://www.rohlik.cz",
"ROHLIK_DEBUG": "true"
}
}
}
}
```
**View logs:**
```bash
# macOS
tail -f ~/Library/Logs/Claude/mcp-server-rohlik-local.log
# Windows
type %APPDATA%\Claude\logs\mcp-server-rohlik-local.log
```
### Using the API Validation Tool
If you encounter authentication or API issues, run the validator:
```bash
npm run validate-api
```
This will:
- Test all 11 API endpoints used by the MCP
- Show detailed HTTP request/response information
- Generate `validation-results.json` with test results
- Create `validation-report.html` for easy viewing in browser
- Help identify which specific endpoints are failing
### Publishing as NPM package
1. Update version in package.json
```bash
# Patch: 3.1.1 → 3.1.2
npm version patch
# Minor: 3.1.1 → 3.2.0
npm version minor
# Major: 3.1.1 → 4.0.0
npm version major
```
2. `npm publish --access public`
