Model Context Protocol (MCP)
@MCP_Community
“the entire @Klavis_AI team for turning complex MCP infrastructure into plug-and-play simplicity. Enterprise-grade tools without the enterprise headaches!”
Shoya
Founder and CEO @ Jinba (YC W26)
“I subscribed because I knew you guys would ship faster than anyone else, and you have. Replies within a minute, even at 2am. That level of commitment from both of you is truly outstanding.”
Bill Clerico
Former CEO @Wepay
“If you're a VC using @affinity__crm I highly recommend the Klavis MCP server to give Claude access to your Affinity data. You can now get a pretty good investment memo draft with just a simple ask, amongst lots of other stuff!”
Fireworks AI
“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.”
Justin Lee
Co-Founder at Den (YC X25)
“these guys don't just sell the best servers, they answer on the first ring, every time. If you need MCP, use Klavis.”
Guillermo Flor
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”
CrewAI
“Automate your next sales follow-up! All powered by CrewAI + Klavis AI (YC X25) MCP — no manual coding of OAuth flows, no glue scripts.”
CAMEL-AI
“We're excited to announce integration with @Klavis_AI MCP platform Now your Camel agents can Unlock seamless tool discovery and supercharge your AI agents”
Llamaindex
“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!.”
Together AI
“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.”
