Stainless will wind down its hosted products as the team shifts focus to Claude Platform capabilities. Analysts say the deal reflects a broader industry shift where AI vendors compete on developer infrastructure and agent connectivity, not just model performance. The acquisition also raises governance concerns around API sprawl and security controls from rapidly generated MCP servers. ## Full article daily.dev links to this article rather than hosting it.
