Onescreen Wins Zapa as Self‑Serve CTV Client
Munich-based streaming ad start-up Onescreen has secured its first reference customer: dental brand Zapa.

Zapa booked and ran a streaming campaign via Onescreen’s platform—targeting relevant households on premium streaming platforms such as Netflix—using its own shopper and marketing data. Onescreen offers dashboard metrics including impressions, completed views and household contacts and positions its Ad Manager as an alternative to traditional TV buying for small and medium-sized enterprises.

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.
