Future Enhancements

We have several ideas for future enhancements to the Opera Omnia MCP server:

1. Advanced Content Generation: Add more sophisticated content generation capabilities beyond simple template substitution.

2. Improved Caching: Implement better caching mechanisms for improved performance, especially for frequently accessed datasets.

3. User-Contributed Datasets: Add support for user-contributed datasets, allowing users to extend the available content.

4. Visualization Tools: Create visualization tools for exploring the data and understanding relationships between different datasets.

5. Local Data Files: Add support for local data files as an alternative to fetching from GitHub.

6. Integration Examples: Provide more examples of integrating the MCP server with different applications and frameworks.
