Summary

The MCP Dev Summit North America 2026, held April 2-3 at the New York Marriott Marquis, gathered approximately 1,200 attendees to discuss the Model Context Protocol (MCP) ecosystem. Organized by the Linux Foundation's Agentic AI Foundation, the summit highlighted MCP's evolution from experimental origins to a production-ready integration protocol. Key developments included new transport work (SEP-1442) moving towards stateless requests, and the official release of MCP Apps on January 26, 2026, enabling interactive UI for clients. Major enterprises like Amazon and Uber showcased their extensive internal MCP deployments, with Uber processing tens of thousands of agent executions weekly. A dominant architectural consensus emerged around the gateway pattern for managing agent interactions at scale, and context bloat was reframed as a client-side problem, with Anthropic's Claude Code demonstrating 85% token usage reductions through progressive tool discovery.

Key takeaway

For CTOs and VPs of Engineering evaluating agentic AI integration, the widespread adoption of the Model Context Protocol (MCP) by major enterprises like Amazon and Uber signals its readiness for production. You should prioritize implementing a centralized MCP gateway and registry to manage agent interactions, ensuring governance, authorization, and PII redaction. Consider adopting MCP Apps to enhance agent interactivity and explore stateless transport mechanisms to future-proof your agentic infrastructure.

Key insights

MCP is maturing into a critical enterprise integration protocol for agentic AI, driven by stateless transports and gateway architectures.

Principles

• Stateless requests enhance protocol scalability.
• Gateways centralize agent interaction governance.
• Context bloat is a client-side optimization problem.

Method

Enterprises like Uber implement an MCP Gateway and Registry as a control plane, exposing internal endpoints to agents while performing PII redaction and scrubbing identifiers before external model requests.

In practice

• Implement a gateway pattern for agentic AI deployments.
• Utilize MCP Apps for interactive agent UIs.
• Employ progressive tool discovery to manage context windows.
