Error Handling

The server includes comprehensive error handling for:

  • Invalid authentication credentials
  • Repository not found
  • Branch not found
  • Pull request not found
  • Insufficient permissions
  • API rate limiting
  • Network connectivity issues

Errors are returned with descriptive messages to help troubleshoot issues.

Security

  • Uses Bitbucket App Passwords (more secure than regular passwords)
  • Credentials are stored as environment variables
  • All API communications use HTTPS
  • No credentials are logged or exposed in responses

API Rate Limits

Bitbucket API has rate limits. The server will return appropriate error messages if limits are exceeded. Consider implementing exponential backoff for high-frequency operations.

Building

npm run build

Running Locally

# Set environment variables
export BITBUCKET_USERNAME="your-username"
export BITBUCKET_APP_PASSWORD="your-app-password"
export BITBUCKET_WORKSPACE="your-workspace"

# Run the server
node build/index.js

Troubleshooting

Common Issues

  1. Authentication Failed

    • Verify your App Password is correct
    • Ensure your username is correct (use email if that's how you log in)
    • Check that the App Password has the required permissions

  2. Repository Not Found

    • Verify the repository name is correct (case-sensitive)
    • Ensure you have access to the repository
    • Check that the workspace name is correct

  3. Branch Not Found

    • Verify the branch name exists in the repository
    • Check for typos in branch names
    • Ensure the branch hasn't been deleted

  4. Server Not Starting

    • Check that all environment variables are set
    • Verify the build completed successfully
    • Check the Node.js version compatibility

Debug Mode

To enable detailed logging, you can modify the server code to include debug statements or check the MCP client logs for detailed error information.

Contributing

This MCP server provides comprehensive Bitbucket integration. To extend functionality:

  1. Add new tool definitions in the setupToolHandlers() method
  2. Implement the corresponding handler methods
  3. Update this documentation
  4. Test thoroughly with your Bitbucket repositories
