OpenAI Agents SDK

Verification notes: New listing, added this pass — distinct from the existing ChatGPT Agent listing, which covers OpenAI's consumer-facing browsing agent rather than this developer framework. MIT licensed (github.com/openai/openai-agents-python, confirmed via the repository's LICENSE file and pyproject.toml). Built-in MCP server tool calling is documented as a core feature, letting agents call remote MCP tools alongside native function tools. No A2A support is documented; treat that as unconfirmed rather than absent. OpenAI is winding down the no-code Agent Builder and Evals products (deprecation announced June 3, 2026, off-platform November 30, 2026) and steering code-based workflows toward this SDK instead, comparable in role to LangChain or CrewAI. Re-checked this pass: the A2A Protocol Foundation reached v1.0 in April 2026 across the broader ecosystem (signed Agent Cards, 150+ production organizations), but that milestone is protocol-wide rather than a claim OpenAI itself makes about this SDK — no OpenAI-authored documentation for openai-agents-python confirms native A2A support, so the flag stays false.
