A few gateways / aggregators that could be added

[tleyden]

I'm searching for a good self-hosted open source MCP aggregator, here are a few that I've come across so far that could be listed under the aggregators section:

1. https://github.com/Klavis-AI/klavis
2. https://github.com/obot-platform/obot
3. https://github.com/tuananh/hyper-mcp

Also https://github.com/metorial/metorial, but there is already a PR open here: #1430

Let me know if you want me to provide detailed descriptions or open a PR for any of these.
