Klavis AI is a Y Combinator (X25) backed startup providing open-source infrastructure for integrating Model Context Protocols (MCPs) into AI applications at scale. Founded by Xiangkai Zeng (ex-Google DeepMind, Gemini function calling) and Zihao Lin (ex-Lyft), we solve the critical challenges of tool connectivity, security, and scalability for AI agents. Our platform addresses key industry problems: the lack of built-in, user-based authentication in existing MCP servers and the instability of underdeveloped personal projects. Our flagship product, Strata, enables AI agents to handle thousands of tools through progressive discovery, preventing context overload. This approach is proven to improve agent accuracy on complex tasks by over 13%, achieving 83%+ accuracy on multi-app workflows. Klavis AI provides 100+ production-ready MCP servers with enterprise OAuth support for major services like GitHub, Slack, and Salesforce, with flexible deployment options including a hosted service, self-hosted Docker, SDKs (Python/TypeScript), and a direct REST API.
