Reviewer Notes

Teams has solid documentation and a real OpenAPI spec, plus reliable infrastructure and good sandbox support, making it moderately discoverable and reliable. However, it has no MCP server and critical weaknesses: account creation requires human organizational setup (no programmatic account creation for agents), OAuth2 is mandatory with no simple API key alternative, and free tier is limited to personal use only—enterprise agents need costly Microsoft 365 subscriptions. These barriers significantly limit autonomous agent adoption compared to API-first platforms.
