Anthropic acquired Stainless — the startup that generates official SDKs for OpenAI, Google, Cloudflare, Replicate, and hundreds of others — for a reported $300M+. The hosted SDK generator will be wound down, meaning competitors lose access to the automated multi-language library generation Stainless has provided since 2022. The acquisition positions Anthropic to control the MCP server tooling layer as agent connectivity becomes the key platform battleground.
Semble (v0.1.7, May 12) is a code search library for AI agents that uses ~98% fewer tokens than grep+read while matching 99% of the retrieval quality of much heavier transformer-based approaches. It indexes a repository in 263ms and answers queries in 1.5ms on CPU, ships as an MCP server for Claude Code, Cursor, and Codex, and requires no API keys, GPU, or external services. The design bets that static embeddings plus BM25, fused carefully and reranked with code-specific signals, are almost as good as a code-specialized transformer — and orders of magnitude cheaper to operate.
