A study on how the Model Context Protocol (MCP) compares to traditional control plane architectures for orchestrating agentic applications. It contains the technical differences, expert and community opinions, and examines any evidence of real-world adoption or use cases for both approaches.
The Model Context Protocol (MCP) is a recently proposed open standard (originating from Anthropic) that defines how AI models (especially LLM-based agents) connect to external tools and data sources in a consistent way. By contrast, traditional “control plane” architectures in agentic AI refer to custom or framework-based orchestrators that manage how one or multiple AI agents invoke tools, coordinate tasks, and enforce policies. This report compares MCP with traditional control-plane designs for orchestrating agentic applications, focusing on technical differences in architecture and communicat
