The report identifies a mindset trap that's holding most organizations back: "inside-out" integration thinking.
Inside-out means viewing integration from the perspective of only prioritizing the reuse of legacy integrations and architecture (i.e., simply wrapping existing integrations with MCP and calling it agent-ready) and forcing the agent to work within that paradigm. It's the natural instinct for teams that have spent years deploying iPaaS or managing brittle, scattered APIs with manual registration and configuration change workflows, inadequate documentation, and no clear ownership.
This perspective sounds like: “Build another connector, develop many layers of 'orchestration logic,' and just sweep the legacy APIs under the carpet of 'agentic' workflows." The instinct there might be to layer the agents on top of this type of hard-coded, DSL-driven, business logic and low-quality APIs by simply wrapping them with MCP–without thinking from the agent’s perspective first.
The problem is that this approach treats agents as just another consumer of existing services. It doesn't account for what agents actually need: the ability to autonomously navigate across systems, discover relevant tools at runtime, maintain context across multi-step workflows, and take actions on behalf of users with proper authorization.
Gartner contrasts this with "outside-in" integration — starting from the agent's goal and the user's needs, then architecting the internal technology environment to support that journey. Outside-in means building delegated identity so agents can act with proper authorization. It means real-time data foundations, so agents aren't reasoning on stale information. It means hybrid connectivity that combines dynamic discovery with deterministic reliability.
The shift from inside-out to outside-in isn't incremental. It's architectural. And it explains why traditional integration approaches — including iPaaS—will struggle in the agentic era.
