Mediaocean, Disney launch Prisma Direct for Disney CTV
Mediaocean and The Walt Disney Company announced a partnership to introduce Prisma Direct, a new workflow layer inside Mediaocean’s Prisma system that will roll out in Q3. The API-driven integration connects media buyers directly to Disney’s CTV and streaming inventory, automating ordering, activation, analytics and billing to reduce manual insertion orders and fragmented workflows. Built on the same technology as Disney Campaign Manager, Prisma Direct gives buyers access to premium inventory (including sponsorships and high-impact placements) while preserving publisher decisioning, bidding, and measurement within existing stacks. Mediaocean frames the product as workflow consolidation and cost reduction rather than disintermediation, though the integration raises questions about potential alternative buying rails for guaranteed CTV and premium video outside traditional DSP-driven programmatic channels.
Guideline.ai Revolutionizes Media Planning with AI Insights
Guideline.ai, an AI-powered media intelligence platform founded in 2020, aims to remove guesswork from media planning by aggregating real transaction data from agency billing systems into anonymized, industry-wide benchmarks on spend and performance. The company describes a 'give to get' data-sharing model with holdcos and large independents, returning an executive dashboard with actionable insights while preserving privacy. By combining actual historical spend by publisher, unit types, and pricing, Guideline.ai seeks to help agencies plan more effectively, defend budgets, justify spend to clients, and negotiate stronger terms with publishers. The platform also leverages AI to extract qualitative trends from data. Kelley Train, Guideline.ai's VP of Data and Strategic Alliances, advocates data-driven decision making and notes past roles at Omnicom Media Group and PHD Worldwide.
Guideline Unveils AI-Driven Media Plan Management Server
Guideline announced the launch of its Media Plan Management MCP Server, a product that lets agencies, media buyers, and enterprise clients connect their own AI agents directly to Guideline’s media plan management platform using the open Model Context Protocol (MCP).

Guideline positions the MCP Server as the first in a series of MCP-enabled features across its suite. The article notes MCP was introduced by Anthropic and is supported by major AI platforms and cites an industry projection that 75% of enterprise gateway vendors will integrate MCP capabilities by end of 2026.
