FAQs

Does YouGov provide API access to opinion data streams?

YouGov offers API access to our flagship data product solutions; brand tracking and brand health data via YouGov BrandIndex API or audience profiling data via YouGov Profiles API. Our APIs enable direct integration of YouGov data for business intelligence tools, marketing platforms, AI solutions, or custom applications requiring real-time opinion data. 

What is BrandIndex MCP?

BrandIndex MCP connects YouGov BrandIndex data to your AI assistant through Model Context Protocol, an open standard for linking AI tools to external data. You ask a question in natural language, and the MCP turns it into Brandindex API requests. Your assistant then receives the brand health data and works with it directly, with no exports or file uploads.

What's the difference between BrandIndex API and BrandIndex MCP?

The API is built for developers who want to move BrandIndex data into their own systems, dashboards and models. The MCP is built for AI-powered workflows. It lets AI assistants retrieve BrandIndex data as part of a conversation, so non-technical users can explore it without writing code. Both serve the same underlying BrandIndex data.

What can I do with BrandIndex MCP?

You can explore the markets, sectors, and brands your account covers. You can compare named brands across any of the 16 BrandIndex metrics, filter by core demographics, category or metric filters, and see results as a daily trend or as weekly to yearly figures. You can also save analyses as charts in BrandIndex.

The MCP returns aggregated brand metrics only, not respondent-level data or open-ended responses. Your AI assistant handles any summaries, visuals, or reports you ask for it to create from that data.

How accurate is the data MCP produces?

Every value the BrandIndex MCP returns comes from the BrandIndex API and is verified against it. How your AI assistant interprets or presents those figures is up to your AI tool, and AI models can make mistakes. Treat the retrieved figures as authoritative and your assistant's commentary as a draft. Check any figures before they go into a report or presentation.

Which AI tools work with BrandIndex MCP?

BrandIndex MCP works with any MCP-compatible AI client. Setup guides for popular clients are available in the BrandIndex MCP documentation.

Who can access BrandIndex MCP?

BrandIndex MCP access is licensed separately from BrandIndex platform and API access. Users sign in securely with their own YouGov account, and the MCP follows their existing BrandIndex permissions, so each person can only query the markets, sectors and data their account covers. Contact your account manager to enable MCP access.

Is there public documentation for BrandIndex API, or do I need credentials to view it?
