Onescreen opens early access to OOH data inside AI workflows

Onescreen is giving planners, agencies and brands early access to an MCP server that plugs OOH audience, market and inventory data into AI tools like Claude and ChatGPT. The move aims to replace spreadsheet-heavy research with faster, data-grounded planning inside the workflows teams already use.

Why it matters: - Onescreen is trying to make out-of-home planning behave more like digital advertising, where teams can query data and act faster. - The MCP server could reduce the time planners spend stitching together vendor decks, spreadsheets and manual research. - Onescreen says the workflow is designed to give AI assistants real inventory and audience context instead of generic planning guesses.

What happened: - Onescreen announced early access to a public Model Context Protocol, or MCP, server on June 23, 2026. - The server connects Onescreen’s OOH research data to Claude, ChatGPT or other AI clients. - The data set includes audience personas, market and inventory rankings, and close to 1 million live listings. - Media strategists can use an AI assistant to rank inventory for a specific audience, such as Chicago billboards for Blue Line commuters earning $90,000 or more.

The details: - Onescreen Research is free and includes more than 1,500 OOH audience personas, close to 1 million inventory listings and audience-based market and inventory recommendation services. - Onescreen Planner is in closed beta by invitation for select design partners, including brand marketers, OOH specialists and supply-side teams. - The Planner tier increases rate limits, unlocks permission-based pricing intelligence and supports automated RFP workflows. - The planning tools are wired into Onescreen’s media planning and buying products. - Users connect Onescreen to an AI client like any other app, without a new interface or separate login. - Onescreen says users can ask questions the way they would ask a colleague, and the assistant will pull the data it needs. - The company’s example prompt asks for the best OOH inventory to reach health-conscious shoppers in Chicago, with a mix of frequency formats and large bulletins, plus a map view and points of interest. - Greg Wise, co-founder and chief customer officer, said Onescreen’s planners and media strategists already use the MCP server inside Claude Cowork for campaigns for Rippling and California Naturals. - Andy Luther, CTO, said the harder part was making market, vendor and audience data behave like one resource an agent can use.

Between the lines: - Onescreen is positioning MCP as infrastructure for a workflow shift, not just a new product feature. - The company is betting that planners want answers embedded in their existing AI environment, not another dashboard. - The launch also signals how AI tools are moving from drafting help toward data-connected decision support in specialized media buying.

What's next: - Onescreen Research is available now at access request. - Media planners and supply-side teams can apply for access to the closed beta planning tools. - Onescreen says those partners will help shape the roadmap for the next phase of the product.

The bottom line: - Onescreen is opening its OOH data stack to AI assistants in an effort to make outdoor media planning faster, more searchable and more grounded in live inventory data.
