Replace path/to/opera-omnia-mcp
with the actual path to this project.
List all available data categories.
const result = await use_mcp_tool({ server_name: "opera-omnia", tool_name: "list_categories", arguments: {} });
List all datasets within a category.
const result = await use_mcp_tool({ server_name: "opera-omnia", tool_name: "list_datasets", arguments: { category: "characters" } });
Get the complete contents of a specific dataset.
const result = await use_mcp_tool({ server_name: "opera-omnia", tool_name: "get_dataset", arguments: { category: "characters", dataset: "personalities" } });
Get a random item from a specific dataset.
const result = await use_mcp_tool({ server_name: "opera-omnia", tool_name: "get_random_item", arguments: { category: "characters", dataset: "personalities" } });

const result = await access_mcp_resource({ server_name: "opera-omnia", uri: "opera-omnia://categories" });
List of datasets available in a specific category.
const result = await access_mcp_resource({ server_name: "opera-omnia", uri: "opera-omnia://category/characters" });
Contents of a specific dataset.
const result = await access_mcp_resource({ server_name: "opera-omnia", uri: "opera-omnia://dataset/characters/personalities" });
We have several ideas for future enhancements to the Opera Omnia MCP server:
Advanced Content Generation: Add more sophisticated content generation capabilities beyond simple template substitution.
Improved Caching: Implement better caching mechanisms for improved performance, especially for frequently accessed datasets.
User-Contributed Datasets: Add support for user-contributed datasets, allowing users to extend the available content.
Visualization Tools: Create visualization tools for exploring the data and understanding relationships between different datasets.
Local Data Files: Add support for local data files as an alternative to fetching from GitHub.
Integration Examples: Provide more examples of integrating the MCP server with different applications and frameworks.
