YouGov Expands BrandIndex Data Access Through MCP

On October 8, 2026, YouGov expanded Model Context Protocol (MCP) support to its BrandIndex platform. Marketers and research teams can now request brand health metrics directly from ChatGPT, Claude, Microsoft Copilot, and other compatible AI tools. The connection enables users to work with YouGov data without constantly switching between BrandIndex and AI applications.

Which BrandIndex Metrics Are Available Through MCP

The integration provides access to brand Awareness, Consideration, Purchase Intent, Ad Awareness, Brand Perception, and other BrandIndex metrics.

Users can submit requests in natural language, such as comparing purchase intent for two competing brands over the past six months or checking how perceptions of a company changed after an advertising campaign. The integration supports time series, brand comparisons, and data filtering by market and audience characteristics.

MCP connects directly to the BrandIndex API. YouGov supplies the underlying metrics, while the user's AI tool performs the interpretation, generates conclusions, and creates visualizations. BrandIndex data is updated daily, although the availability of individual metrics depends on survey processing timelines.

Connecting BrandIndex MCP and Understanding Its Limits

BrandIndex MCP operates through a remote server using OAuth 2.0 authorization. Access is governed by the user's BrandIndex permissions, so an AI tool can retrieve only the data, markets, and categories covered by that user's subscription.

MCP requires a separate license. It is not automatically included with access to BrandIndex or its API.

The integration returns aggregated metrics but does not expose individual respondents' answers. It also does not independently test the statistical significance of differences. YouGov recommends checking conclusions generated by AI models because accurate API data does not guarantee that an AI system will interpret it correctly.
