```powershell
# Run the configuration paths script
.\ConfigurationPaths.ps1
```

This script will display:
- Python executable path
- Server script path
- Workshop path
- **Claude Desktop format** (JSON with forward slashes `/`)
- **MCP Inspector format** (Windows with backslashes `\`)

**Configure in MCP Inspector UI:**
1. **Transport Type**: Select `STDIO`
2. **Command**: Paste the `python.exe` path (Windows format with backslashes)
3. **Arguments**: Paste the `server_workshop.py` path (Windows format)
4. **Environment Variables** (optional):
   - Key: `PYTHONPATH`
   - Value: Your workshop path

**Test Your Server:**
- Click "Connect" to start the server
- Browse the **Tools** tab to see all 6 available tools
- Click any tool and fill parameters to test it
- Check **Prompts** tab for `customer_analysis` and `pricing_analysis`
- Inspect **Resources** tab to view available data files

**Benefits:**
- ✅ Visual interface for debugging
- ✅ Test tools individually without Claude Desktop
- ✅ Inspect JSON request/response data
- ✅ Faster iteration during development

> 📖 **For detailed instructions**, see Step 6-7 in [WORKSHOP_GUIDE_EN.md](WORKSHOP_GUIDE_EN.md)

```powershell
# Run the automated configuration script
.\configure_claude.ps1
```

This script will:
- ✅ Auto-detect all required paths
- ✅ Backup your existing configuration
- ✅ Create/update Claude Desktop config with correct paths and PYTHONPATH
- ✅ Validate the JSON configuration
- ✅ Open the config file for review
- ✅ Show you the next steps

Then restart Claude Desktop and start using your MCP tools!

---

**Option B: Manual Configuration**

**Get your paths first:**
```powershell
# Run the configuration paths script
.\ConfigurationPaths.ps1
```

Copy the paths from the "FOR CLAUDE DESKTOP (JSON format)" section.

**Edit your Claude Desktop configuration file:**

**Windows**: `%APPDATA%\Claude\claude_desktop_config.json`  
**macOS**: `~/Library/Application Support/Claude/claude_desktop_config.json`

**Configuration template** (replace paths with yours):
```json
{
  "mcpServers": {
    "bc-workshop-server": {
      "command": "YOUR_PYTHON_PATH_HERE",
      "args": ["YOUR_SERVER_PATH_HERE"],
      "env": {
        "PYTHONPATH": "YOUR_WORKSHOP_PATH_HERE"
      }
    }
  }
}
```

> ⚠️ **Important**: Include the `"env"` field with `PYTHONPATH` to ensure proper module loading.
> 
> 💡 **Quick validation**: Run `Get-Content "$env:APPDATA\Claude\claude_desktop_config.json" | ConvertFrom-Json` to test your JSON.

## 🎓 What is STDIO Transport?

STDIO (Standard Input/Output) transport enables MCP servers to communicate with clients through stdin/stdout streams. This is the standard method for integrating MCP servers with Claude Desktop.

**Key Benefits:**
- ⚡ Fast local communication
- 🔒 No network exposure (secure by default)
- 🎯 Perfect for Claude Desktop integration
- ⚙️ Simple configuration - no ports or networking required

**How it works:**
1. Claude Desktop launches your MCP server as a subprocess
2. Communication happens via standard input/output streams
3. JSON-RPC messages are exchanged over these streams
4. The server provides tools, prompts, and resources to Claude

### STDIO vs HTTP Transport

While this workshop focuses on STDIO transport for Claude Desktop, MCP also supports HTTP-based transport for different use cases:

| Feature | **STDIO** (This Workshop) | **HTTP/SSE** (Alternative) |
|---------|---------------------------|----------------------------|
| **Transport** | stdin/stdout streams | HTTP + Server-Sent Events |
| **Use Case** | Claude Desktop integration | Web integrations, remote access |
| **Network** | Local only | Network-accessible |
| **Setup** | Simple | Requires port configuration |
| **Security** | Isolated by default | Needs HTTPS in production |
| **Best For** | Desktop apps, local tools | Cloud services, webhooks, APIs |

## 🛠️ How to Extend

### Understanding the MCP Server Components

The workshop server demonstrates **three main MCP capabilities:**

#### 1️⃣ **Tools** (Functions Claude can call)
- Located in: `server_workshop.py` → `handle_list_tools()` and `handle_call_tool()`
- Examples: `get_customers`, `get_items`, `get_currency_exchange_rates`
- **How to add your own:**
  ```python
  # In handle_list_tools(), add:
  types.Tool(
      name="your_tool_name",
      description="What your tool does",
      inputSchema={
          "type": "object",
          "properties": {
              "param1": {"type": "string", "description": "Parameter description"}
          }
      }
  )
  
  # In handle_call_tool(), add:
  elif tool_name == "your_tool_name":
      result = await client.your_api_method(arguments.get("param1"))
      return [types.TextContent(type="text", text=json.dumps(result))]
  ```

#### 2️⃣ **Prompts** (Pre-configured Claude prompts)
- Located in: `server_workshop.py` → `handle_list_prompts()` and `handle_get_prompt()`
- Examples: `customer_analysis`, `vendor_analysis`
- **How to add your own:**
  ```python
  # In handle_list_prompts(), add:
  types.Prompt(
      name="your_prompt_name",
      description="What your prompt does",
      arguments=[
          types.PromptArgument(
              name="param1",
              description="Parameter description",
              required=True
          )
      ]
  )
  
  # In handle_get_prompt(), add case for your prompt
  ```

#### 3️⃣ **Resources** (Static data files)
- Located in: `server_workshop.py` → `handle_list_resources()` and `handle_read_resource()`
- Examples: CSV and JSON files in `data/` folder
- **How to add your own:**
  ```python
  # In handle_list_resources(), add:
  types.Resource(
      uri=AnyUrl("file://data/your_file.csv"),
      name="Your Resource Name",
      description="What this resource contains",
      mimeType="text/csv"
  )
  ```
