Out-of-Home (OOH) Advertising / AI Workflows Market: Onescreen Opens MCP Server for OOH AI Workflows

Onescreen announced early access to its public Model Complex Protocol (MCP) server, which exposes Onescreen’s out-of-home (OOH) research data — including audience personas, market and inventory rankings, and nearly one million live listings — to AI clients such as Claude and ChatGPT. Built on the Model Context Protocol open standard, the server lets media planners and strategists query real OOH inventory and audience-based ranking models directly from their AI assistants, reducing manual spreadsheet workflows. Onescreen is offering a free tier (Onescreen Research) and an invitation-only closed beta (Onescreen Planner) that adds higher rate limits, permissioned pricing intelligence, and automated RFP workflows. The company says the capability is already used internally and on campaigns for brands like Rippling and California Naturals.
