xby-ons-data: An MCP Server for Accessing UK Office for National Statistics Data

`xby-ons-data` is an MCP server plugin in the DeepSeek Harness (DSH) ecosystem for accessing the UK Office for National Statistics (ONS) Beta API. It simplifies the integration of official statistical data through standard commands—such as setting an API key, searching or retrieving datasets, and fetching observations—without requiring users to manage API keys manually. Users must first register on the official website to obtain a key, then install and enable the plugin via the DSH command line.
