Stainless is an API developer experience platform that enables companies to automatically generate robust SDKs, synchronized API documentation, and Model Context Protocol (MCP) servers directly from OpenAPI specifications. Built for modern API-first businesses and AI-driven ecosystems, Stainless helps organizations deliver best-in-class developer tooling and agent-ready infrastructure without manually maintaining SDKs or documentation across multiple programming languages. The platform supports generation of idiomatic SDKs for TypeScript, Python, Go, Java, Ruby, C#, PHP, and other major languages, ensuring developers can integrate APIs using language-native patterns and tooling. Stainless continuously derives SDKs and documentation from a centralized OpenAPI specification, allowing documentation and client libraries to remain automatically aligned with evolving APIs and reducing maintenance complexity for engineering teams. In addition to developer tooling, the platform supports state-of-the-art MCP server generation, enabling AI agents and AI-powered systems to interact with APIs more effectively through standardized interfaces. Stainless is used by API-focused technology companies and infrastructure providers seeking to improve onboarding, reduce integration friction, accelerate adoption, and provide consistent developer experiences at scale. By automating SDK generation, documentation synchronization, and MCP infrastructure from a single API specification, Stainless helps engineering organizations deliver reliable, scalable, and agent-friendly API ecosystems more efficiently.
