}

Mac and Linux

{
  "mcpServers": {
    "bitbucket-api": {
      "command": "uv",
      "args": [
        "run",
        "--directory", "/path/to/mcp-bitbucket",
        "-m", "mcp_bitbucket.server"
      ],
      "env": {
        "BITBUCKET_USERNAME": "your-username",
        "BITBUCKET_APP_PASSWORD": "your-app-password"
      }
    }
  }
}

⚠️ Important: You must restart Claude Desktop after modifying the configuration file.

Usage

Once configured, the Bitbucket tools will be available in Claude Desktop. You can:

• Ask Claude to create repositories and branches
• Read and write files in your repositories
• Create and manage issues
• Search for repositories
• Create pull requests
• Manage repository files

Example queries:

• "Create a new repository called 'my-project' in my personal workspace"
• "Create a new branch called 'feature-xyz' in the my-project repository"
• "Create a README.md file in my-project with some basic content"
• "Search for repositories that contain 'python' in the name"

Workspace Configuration

The tools default to the "kallows" workspace, but you can:

• Specify a different workspace using the workspace parameter
• Use workspace='~' to work with your personal workspace
• Create repositories in team workspaces if you have permissions

Running Tests

The project includes unit and integration tests:

# Run all tests
python -m unittest discover tests

# Run specific test files
python -m unittest tests.test_bb_api
python -m unittest tests.test_bb_integration

# Run with verbose output
python -m unittest discover tests -v

Development

Adding New Tools

1. Add the tool definition to handle_list_tools() in server.py

2. Add the implementation to handle_call_tool() in server.py

3. Add corresponding tests

4. Update this README

Error Handling

The server includes comprehensive error handling:

• Permission errors with helpful guidance
• Network connectivity issues
• Invalid parameters and validation
• Bitbucket API rate limiting
