MCP does not replace your iPaaS or Boomi. Boomi and MuleSoft move, transform, and reconcile data between systems with error handling, scheduling, and monitoring, none of which the Model Context Protocol provides. MCP gives an AI agent a standard channel to invoke actions at run time, while the iPaaS remains the layer that governs how data flows across the estate. A commissioned Forrester Total Economic Impact study from September 2025 reported 347% ROI for the Boomi platform over three years, which is a vendor-sponsored result but a signal that the integration layer keeps its own value. The durable pattern is to keep the iPaaS where it works and add a governed MCP layer where agents need to act.
