Fully managed live MCP sandbox environments for training and evaluating AI models on agentic tool use. We handle auth, state resets, and parallel isolation—supporting 1,000+ concurrent runs so you focus on building better models.
Simple tasks don't prepare agents for production. Train on complex, long-horizon workflows in environments that mirror the real world.

@MCP_Community
“the entire @Klavis_AI team for turning complex MCP infrastructure into plug-and-play simplicity. Enterprise-grade tools without the enterprise headaches!”
“Today, we are launching and open-sourcing Eval Protocol: a framework to run RL directly on your production agents. EP brings the training loop to your agent wherever it lives—with day-0 integrations including Klavis AI (YC X25)—streams traces back, and computes rewards to update the model.”
Founder @The AI Opportunity
“Xiangkai built the tool-calling infra at Google Gemini — before MCPs even existed 🤯 He saw the limits of traditional APIs for agents. And knew the real unlock wasn't smarter models”
“Automate your next sales follow-up! All powered by CrewAI + Klavis AI (YC X25) MCP — no manual coding of OAuth flows, no glue scripts.”
“Build AI agents that connect to YouTube, Gmail and other services in just a few lines of code using LlamaIndex and @Klavis_AI's MCP servers!.”
“Congrats to the Klavis AI (YC X25) team! Now you can use Together AI + MCP servers to securely connect tools like Salesforce & Gmail and let AI run real workflows.”
