Infillion Launches MCP-Based Agent Connector

Executive Signal Summary

Infillion launched the Infillion Agent Connector, a fully agentic media execution platform built on the open-source Model Context Protocol (MCP). The connector enables AI agents and LLMs to interoperate across Infillion’s APIs and with each other to manage the full campaign lifecycle — planning, budgeting, targeting and analysis — without requiring direct API-to-API integrations. Stagwell is an early customer and the connector integrates with the MediaMath platform where campaigns are launched and historical campaign data is stored. Infillion describes the platform as AI-agnostic and composable, allowing advertisers to use their own agents or off-the-shelf options and to deploy within preferred cloud or tech environments. Company executives framed the development as part of a shift from a programmatic era to an 'agentic' era for digital advertising.

High Confidence

A notable product launch that applies the MCP open standard to enable agentic, end-to-end campaign execution and composable deployments; signals a practical step toward agentic workflows in adtech but is not a major-platform policy or industry‑wide mandate.
