Anthropic Acquires Stainless to Supercharge Claude Agent Connectivity
Anthropic announced today its acquisition of Stainless, the developer tools startup behind SDKs and MCP server tooling widely used by OpenAI, Google, Cloudflare and hundreds of other AI companies. The deal brings in-house critical infrastructure for connecting AI agents to external data sources and tools, accelerating Anthropic’s push into enterprise agentic workflows.
This move gives Anthropic a strategic edge in the agent arms race by controlling the plumbing that powers rival models too—potentially reshaping how frontier labs build connected AI systems.
