   - Double-click the downloaded `.mcpb` file, or
   - Drag and drop the file into Claude Desktop, or
   - Click "Install from file" in the Extensions settings
4. Configure your X API credentials in the extension settings:
   - `X_API_KEY`: Your API Key (Consumer Key)
   - `X_API_SECRET`: Your API Secret (Consumer Secret)
   - `X_ACCESS_TOKEN`: Your Access Token

- Restart Claude Desktop completely
- Check the logs at:
  - **macOS:** `~/Library/Logs/Claude/mcp*.log`
  - **Windows:** `%APPDATA%\Claude\logs\mcp*.log`

### Manual Setup

#### 1. Open the Claude Desktop config file

You can access the config file either through Claude Desktop settings or directly:

**Via Claude Desktop:**
- Go to **Settings → Developers → Edit Config**

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

#### 2. Add the MCP server entry

Append the following configuration (adjust paths as needed):

**macOS/Linux:**
```json
{
  "mcpServers": {
    "x-twitter": {
      "command": "node",
      "args": ["/Users/username/path/to/x-mcp-server/dist/index.js"],
      "env": {
        "X_API_KEY": "your_api_key",
        "X_API_SECRET": "your_api_secret",
        "X_ACCESS_TOKEN": "your_access_token",
        "X_ACCESS_TOKEN_SECRET": "your_access_token_secret"
      }
    }
  }
}
```

**Windows:**
```json
{
  "mcpServers": {
    "x-twitter": {
      "command": "node",
      "args": ["C:\\Users\\username\\path\\to\\x-mcp-server\\dist\\index.js"],
      "env": {
        "X_API_KEY": "your_api_key",
        "X_API_SECRET": "your_api_secret",
        "X_ACCESS_TOKEN": "your_access_token",
        "X_ACCESS_TOKEN_SECRET": "your_access_token_secret"
      }
    }
  }
}
```

#### 3. Restart Claude Desktop

Restart Claude Desktop completely so the settings take effect.

**macOS:**
- Choose "Quit Claude" from the menu
- Launch Claude Desktop again

**Windows:**
- Terminate Claude Desktop from Task Manager
- Launch Claude Desktop again

#### 4. Verify the connection

After restarting, confirm that the tool icon (🔨) shows up in the bottom-left corner of the Claude input box.

## Usage examples

Ask Claude Desktop things like:

```
"Fetch the latest 10 posts from my home timeline."

"Search for the latest 5 tweets about 'AI technology'."

"Get the latest tweets from @example_user."

"Show me the profile for @example_user."

"Post the tweet 'Hello, this is an MCP server test!'"

"Post a tweet with the text 'Check out this image!' and attach the image at /path/to/image.png"

"Post a tweet with the text 'My new video!' and attach the video at /path/to/video.mp4"
```

## Troubleshooting

### DXT/mcpb installation errors

If you encounter errors when using the DXT/mcpb package:

1. **Verify API keys are correct**
   - Double-check all four credentials (API Key, API Secret, Access Token, Access Token Secret)
   - Ensure there are no extra spaces or quotes in the configuration
   - Verify the keys are valid in the [X Developer Portal](https://developer.x.com/en/portal/dashboard)

2. **Restart Claude Desktop**
   - Completely quit and restart Claude Desktop
   - **macOS:** Choose "Quit Claude" from the menu
   - **Windows:** Terminate Claude Desktop from Task Manager

3. **Check logs for detailed errors**
   - **macOS:** `~/Library/Logs/Claude/mcp*.log`
   - **Windows:** `%APPDATA%\Claude\logs\mcp*.log`

### Claude Desktop does not detect the server

1. Fully restart Claude Desktop
2. Double-check for syntax errors in `claude_desktop_config.json`
3. Ensure the path to `dist/index.js` is correct (use absolute paths)
4. Check the logs:
   - **macOS:** `~/Library/Logs/Claude/mcp*.log`
   - **Windows:** `%APPDATA%\Claude\logs\mcp*.log`

### API errors occur

1. Confirm that environment variables are set correctly
2. Verify that your X app has the required permissions (Read and Write)
3. Ensure the API keys are still valid

### Test the server manually

```bash
# Run in development mode
npm run dev

# Or run the built output
npm run build
node dist/index.js
```

## Development

### Watch mode

```bash
npm run watch
```

In another terminal:

```bash
npm run dev
```
