## Dependencies

- `@modelcontextprotocol/sdk` - SDK for MCP protocol implementation
- `axios` - HTTP client for API requests
- `winston` - Logging framework

## Configuration

The server requires configuration in the VSCode MCP settings file. Here's a sample configuration:

```json
{
  "mcpServers": {
    "bitbucket": {
      "command": "node",
      "args": ["/path/to/bitbucket-server/build/index.js"],
      "env": {
        "BITBUCKET_URL": "https://your-bitbucket-server.com",
        // Authentication (choose one):
        // Option 1: Personal Access Token
        "BITBUCKET_TOKEN": "your-access-token",
        // Option 2: Username/Password
        "BITBUCKET_USERNAME": "your-username",
        "BITBUCKET_PASSWORD": "your-password",
        // Optional: Default project
        "BITBUCKET_DEFAULT_PROJECT": "your-default-project"
      }
    }
  }
}
```

### Environment Variables

- `BITBUCKET_URL` (required): Base URL of your Bitbucket Server instance
- Authentication (one of the following is required):
  - `BITBUCKET_TOKEN`: Personal access token
  - `BITBUCKET_USERNAME` and `BITBUCKET_PASSWORD`: Basic authentication credentials
- `BITBUCKET_DEFAULT_PROJECT` (optional): Default project key to use when not specified in tool calls
- `BITBUCKET_DIFF_MAX_LINES_PER_FILE` (optional): Default maximum lines to show per file in diffs. Set to prevent large files from overwhelming output. Can be overridden by the `maxLinesPerFile` parameter in `get_diff` calls.
- `BITBUCKET_READ_ONLY` (optional): Set to `true` to enable read-only mode

**Note**: With the new optional project support, you can now:

- Set `BITBUCKET_DEFAULT_PROJECT` to work with a specific project by default
- Use `list_projects` to discover available projects
- Use `list_repositories` to browse repositories across projects
- Override the default project by specifying the `project` parameter in any tool call

### Read-Only Mode

The server supports a read-only mode for deployments where you want to prevent any modifications to your Bitbucket repositories. When enabled, only safe, non-modifying operations are available.

**To enable read-only mode**: Set the environment variable `BITBUCKET_READ_ONLY=true`

**Available tools in read-only mode:**
- `list_projects` - Browse and list projects
- `list_repositories` - Browse and list repositories  
- `get_pull_request` - View pull request details
- `get_diff` - View code changes and diffs
- `get_reviews` - View review history and status
- `get_activities` - View pull request timeline
- `get_comments` - View pull request comments
- `search` - Search code and files across repositories
- `get_file_content` - Read file contents
- `browse_repository` - Browse repository structure

**Disabled tools in read-only mode:**
- `create_pull_request` - Creating new pull requests
- `merge_pull_request` - Merging pull requests
- `decline_pull_request` - Declining pull requests  
- `add_comment` - Adding comments to pull requests

**Behavior:**
- When `BITBUCKET_READ_ONLY` is not set or set to any value other than `true`, all tools function normally (backward compatible)
- When `BITBUCKET_READ_ONLY=true`, write operations are filtered out and will return an error if called
- This is perfect for production deployments, CI/CD integration, or any scenario where you need safe, read-only Bitbucket access

## Logging

The server logs all operations to `bitbucket.log` using Winston for debugging and monitoring purposes.
