 The Data Commons [Model Context Protocol (MCP)](https://modelcontextprotocol.io/docs/getting-started/intro) service gives AI agents access to the Data Commons knowledge graph and returns data related to statistical variables, topics, and observations. It allows end users to formulate complex natural-language queries interactively, get data in textual, structured or unstructured formats, and download the data as desired. For example, depending on the agent, a user can answer high-level questions such as "give me the economic indicators of the BRICS countries", view simple tables, and download a CSV file of the data in tabular format.
