AutoGen

Verification notes: Code is MIT licensed, docs CC-BY-4.0. Correction this pass: the merger completed — Microsoft Agent Framework reached GA (v1.0) on April 3, 2026, confirmed via Microsoft's own devblog, and AutoGen is now officially in maintenance mode (bug fixes and security patches only, no new orchestration patterns). Microsoft publishes a dedicated AutoGen-to-Agent-Framework migration guide. See the separate Microsoft Agent Framework listing for the successor project. No public MCP support confirmed for AutoGen itself. Re-checked this pass. Maintenance-mode status has held and hardened: Microsoft's repository notice now states AutoGen 'will not receive new features or enhancements and is community managed going forward,' with only bug and security fixes remaining Microsoft's responsibility. Worth noting for readers comparing the ecosystem: a separate community fork, AG2, continues development outside Microsoft's own AutoGen repository. No change to license, MCP status, or the migration-guide pointer to Microsoft Agent Framework. Correction this pass: the mcp flag moves from false to true. AutoGen's own stable documentation (microsoft.github.io/autogen/stable) and its GitHub README both describe a built-in McpWorkbench (autogen_ext.tools.mcp) that lets AutoGen agents consume MCP servers as tools, demonstrated with a working Playwright MCP server example — native, official support, not a community fork or third-party add-on. No dated changelog entry pins exactly when it shipped, so this likely predates the maintenance-mode declaration and was missed in an earlier pass rather than added recently. No evidence of native A2A support in AutoGen core was found; a2a stays false. Maintenance-mode status and the Microsoft Agent Framework migration path, both noted previously, are unchanged — Microsoft's repository notice still states AutoGen 'will not receive new features or enhancements and is community managed going forward.' The AG2 community fork (github.com/ag2ai/ag2) remains separately and actively maintained.
