Deep Dive into Open Agent SDK (Part 3): MCP Integration in Practice

The previous article looked at the SDK's 34 built-in tools — file read/write, Bash execution, code search — covering common development scenarios. But an Agent's capabilities can't rely solely on built-in tools. You need to connect to databases, call enterprise APIs, and operate internal systems. These require a standardized integration approach. MCP (Model Context Protocol) is designed for exactly this. This article examines how Open Agent SDK uses the MCP protocol to bring external tools into
