Model Context Protocol (MCP spec) vs OpenAI Agents SDK
Model Context Protocol (MCP spec) vs OpenAI Agents SDK: side-by-side comparison of two agent frameworks (no first-party memory layer) systems — architecture, taxonomy, license, pricing, MCP/A2A support, and direct edges.
How they relate
- OpenAI Agents SDK integrates with Model Context Protocol (MCP spec) — OpenAI Agents SDK docs have an MCP page for using MCP servers as agent tools.
