What It Is
The Orchestration Agent is the buyer-facing surface of Magnite Orchestration, a coordination layer for agentic advertising.
Built and operated by the buyer
Magnite's seller agent — the coordination layer
Premium omnichannel inventory
The coordination layer
Buyers connect their own buyer agents to Magnite's seller agent and work against Magnite's pool of premium inventory and supply-side intelligence. Through this connection your agent can:
- Create media plans from a simple RFP or brief.
- Discover available supply and audience opportunities.
- Activate omnichannel campaigns across CTV home screens, audio, and other high-impact formats.
Magnite Orchestration is in active development and testing with early partners, including dentsu and DIRECTV Advertising.
Compatibility
Built on the Model Context Protocol (MCP) as its foundation, the Orchestration Agent is architected to be versatile — designed to support layered extensions like the Advertising Context Protocol (AdCP) today, and to adapt to other similar protocols as the agentic advertising ecosystem evolves.
AdCP gives buyer- and seller-side agents a shared language for campaign goals, inventory, and audience signals. This server supports the AdCP get_adcp_capabilities, get_products, create_media_buy, get_media_buys, and — where available — update_media_buy and get_media_buy_delivery operations. Call adcp_get_adcp_capabilities first to discover exactly what this seller supports.
What you can do
- Discover showcase inventory by full feed, natural-language brief, or iterative refinement.
- Buy by turning selected products into a media buy that distributes immediately.
- Manage buys in flight — pause/resume, cancel, and adjust budget, dates, and targeting (ClearLine brands).
- Report on delivery — impressions, spend, pacing, and breakdowns (ClearLine brands).
Who this is for
Programmatic buyers and developers building buyer agents who want to connect those agents to Magnite and transact against premium inventory programmatically.
