Open Source Summit + Embedded Linux Conference North America 2026

Model Context Protocol (MCP) is quickly becoming a foundational interface for agent–tool interaction, but most implementations today stop at simple, single-server tool exposure. This session explores practical MCP design patterns that move beyond “one server, one agent” toward scalable, interoperable, and ecosystem-friendly architectures.

Based on real-world experimentation and open-source implementations, we will walk through a set of MCP patterns, including:
1. Single MCP Server patterns for tool and data exposure
2. Multi-Server composition and routing patterns
3. MCP Host / Gateway patterns for aggregation and policy control
4. Plugin-style extension patterns that allow third-party MCP servers to integrate without code changes
5. Read vs. write MCP patterns for observability, automation, and feedback loops

The talk focuses on when and why to apply each pattern, common pitfalls, and architectural trade-offs. Attendees will leave with a mental model for designing MCP-based systems that scale from local experiments to ecosystem-level platforms, enabling agents, tools, and platforms to evolve independently while remaining interoperable.
