Anthropic Acquires SDK Platform Stainless
Anthropic is acquiring Stainless, an SDK and MCP server platform that has supported all Anthropic SDKs since the early Anthropic API period; the post does not disclose the deal value, closing timeline, or integration plan.
Why it matters: HKR-H/K/R all pass: Anthropic is buying a core SDK/MCP tooling partner. The post lacks price and closing timing, so this is featured developer-ecosystem news, not P1.
