Agentic Index
Klavis AI vs Stacklok (2026)
Two MCP platforms with open source cores, aimed at different halves of the problem, at 6 and 11 of 14. That verdict is the Agentic Index coverage score, graded from each vendor's own published materials.
Klavis is about access: hosted production MCP servers with built in OAuth across more than six hundred tools, plus the open source Strata server, free to start. Stacklok is about containment: an enterprise MCP platform built on open source ToolHive that runs, governs and secures MCP servers and agent skills in isolated containers, Kubernetes native and self hosted, from the Kubernetes co creators. Klavis connects your agent to tools; Stacklok is what your security team asks for once it has.
This comparison is published by Agentic Index, an independent agentic AI vendor research platform. Klavis AI and Stacklok are each graded against the same 14 capability Agentic Index taxonomy, from the vendor's own public materials under the Agentic Index verification standard, alongside 969 researched vendors. No vendor pays for placement and no vendor has reviewed this page. How this evidence is graded
Choose Klavis AI if
- Getting connected is the current problem and six hundred plus tools with OAuth solves it.
- A hosted free tier means you can start today without infrastructure work.
- You want MCP servers provided rather than a platform for running your own.
Choose Stacklok if
- Documented coverage is nearly twice as deep and governance is the reason you are looking.
- Container isolation per MCP server is the control your security review will require.
- Kubernetes native and self hosted, from the people who built Kubernetes, fits your platform.
