Yes our github page has README for all MCP servers and clients. You can checkout https://github.com/Klavis-AI/klavis.
> Are there discovery endpoints to list the available servers?
Yes. https://docs.klavis.ai/api-reference/mcp-server/get-all-serv.... And we are adding more MCP servers.
> Testing and Eval
Yes it is early access now. If you are interested, shoot me an email at xiangkaiz@klavis.ai and we can talk more.
I would also personally consider just open sourcing everything (or at least core features) as I think you'd still have plenty of customers who would prefer a hosted solution. In my experience, there is surprisingly little overlap between the people who prefer cloud vs. self-hosting, so having a full open source option doesn't cannibalize the product side as much as you might think... people who prefer cloud will mostly still prefer it even if they could self-host instead, and people who prefer self-hosting will generally just look for another project rather than using your cloud service. Just my unsolicited 2 cents.
