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.
Handler is a vibe marketing agent for app marketers. It helps app teams find outlier TikToks, understand what makes them work, and turn proven patterns into clearer creative direction. Todayโs launch focuses on Handler and TikSpy: research winners faster, reduce manual scrolling, and know what to test next.

HandlerHandler's answer:
Handler is built specifically for app marketers who want to find what is already working on TikTok. Instead of guessing content ideas, Handler helps teams discover outlier TikToks, understand winning patterns, and decide what to test next.
Handler's answer:
Handler is focused on TikTok research for app growth, not generic social media management. It helps marketers move faster from โwhat should we post?โ to clear creative direction based on real winning TikToks.
Handler's answer:
Handler is made for app founders, growth marketers, mobile app teams, indie app builders, and agencies that use TikTok to grow consumer apps.
Handler's answer:
Handler was created because app teams spend too much time manually scrolling TikTok trying to understand what content works. We built it to make TikTok research faster, clearer, and more repeatable for app marketers.
Handler's answer:
Handler uses AI analysis, TikTok content research, video metadata extraction, creative pattern detection, and a web-based dashboard to help app marketers find and understand winning TikToks.
Handler's answer:
Handler is currently early, so we are not publishing customer names yet. The product is built for app founders, consumer app teams, growth marketers, and agencies working on TikTok-based app growth.
