The Infillion Agent Connector™ is MediaMath's agent-native media execution layer, enabling AI systems to interact directly with the MediaMath platform through the Model Context Protocol (MCP) open standard. Rather than navigating the platform UI or building custom API integrations, AI agents can discover, plan, manage, and optimize programmatic campaigns through a single, standardized connection.
The Agent Connector is the industry's first MCP-powered execution layer purpose-built for programmatic advertising. It supports any MCP-compatible AI client — including Anthropic's Claude, OpenAI's ChatGPT, custom-built agents, and internal AI orchestration systems — with no proprietary lock-in.
Model Context Protocol (MCP) is an open standard originally developed by Anthropic that provides a universal way for AI systems to connect to external tools and data sources. It defines a structured interface through which an AI agent can:
- Discover what tools and operations are available on a connected platform
- Invoke those tools with structured parameters
- Receive structured results that the AI can reason about and act on
In the context of MediaMath, MCP replaces the need for an AI agent to make raw REST API calls, parse OpenAPI specs, or manage authentication flows manually. Instead, the agent connects to the MediaMath MCP server and immediately has access to a curated set of high-level operations — each with built-in documentation, parameter validation, and contextual guidance — that map to common campaign management workflows.
| Traditional API | MCP Integration | |
|---|---|---|
| Discovery | Developer reads OpenAPI spec, writes integration code | AI agent auto-discovers available tools at connection time |
| Authentication | Developer implements OAuth2 flow, manages tokens | Handled by MCP server; agent inherits user permissions |
| Operations | Raw HTTP calls to individual endpoints | High-level tool calls with built-in business logic |
| Context | Developer must understand entity relationships | Tools include contextual guidance and related-tool suggestions |
| Error Handling | Developer parses HTTP status codes and error bodies | Structured error responses with remediation guidance |
| Target User | Software engineers building integrations | AI agents (and the humans directing them) |
The MCP integration layer sits alongside the existing Campaign Management API V3, Reporting API V2, and other MediaMath APIs. It does not replace those APIs — rather, it provides an AI-optimized interface that orchestrates calls across multiple underlying APIs to deliver cohesive, workflow-oriented operations.

Note: The Agent Connector is under active development and new tools are added regularly. Documentation may not always reflect the latest available tools. We recommend that you periodically check what tools are available in your MCP connection, as your AI agent can discover all current tools automatically upon connecting.
If you have been granted access to the closed beta, see the Getting Connected guide for setup instructions.
