Opera Omnia

You can access and combine Opera Omnia’s rich JSON datasets through an MCP server, enabling automated content generation, dataset filtering, and flexible data retrieval for games, storytelling, and bot development. This MCP server exposes a local runtime you run on your machine, and it connects to a built index of Opera Omnia data to answer your data requests efficiently.

How to use

You interact with the Opera Omnia MCP server through an MCP client. Start the local MCP runtime, then use the available tools to list datasets, fetch specific data, or generate content using templates. You can retrieve full datasets, pick random items, filter by criteria, or combine multiple datasets to craft creative outputs.

How to install

Prerequisites: Node.js installed on your system. You should also have npm available to install dependencies.

Clone the project to your preferred directory.

Install dependencies.

npm install

Build the project.

npm run build

Run the MCP server locally.

npm start

Configuration and usage notes

Configure your MCP client to connect to the Opera Omnia MCP as a local stdio server. Use the following runtime command in your MCP settings.

{
  "mcpServers": {
    "opera_omnia": {
      "command": "node",
      "args": ["path/to/opera-omnia-mcp/build/index.js"],
      "disabled": false,
      "autoApprove": []
    }
  }
}

Examples of common actions

List all data categories available from Opera Omnia.

const result = await use_mcp_tool({
  server_name: "opera_omnia",
  tool_name: "list_categories",
  arguments: {}
});

List all datasets within a category, such as characters.

const result = await use_mcp_tool({
  server_name: "opera_omnia",
  tool_name: "list_datasets",
  arguments: {
    category: "characters"
  }
});

Get a random item from a dataset.

const result = await use_mcp_tool({
  server_name: "opera_omnia",
  tool_name: "get_random_item",
  arguments: {
    category: "characters",
    dataset:="personalities"
  }
});

Notes on data and usage

You can combine multiple datasets or generate content using templates. For example, you can create a sentence by filling in template slots with items drawn from different datasets.

Troubleshooting

If the MCP server fails to start, verify Node.js is installed and that the path to the built runtime is correct. Ensure dependencies are installed and the build completed without errors.

Security and maintenance

Keep the server updated with the latest dependencies and monitor for changes in Opera Omnia datasets. If you expose the MCP server remotely, implement appropriate access controls and review any environment-specific configurations.
