I've been working on MCP developer tools. It has been fun. There are a few MCP gateways out there. They're fine. I've technically built a high-performance, resilient MCP gateway in this codebase, but I'm not currently planning to promote it that way. I think there's a lot of opportunity here.

I will say... for all the MCP gateways out there... proxying from HTTP to a subprocess communicating via stdio isn't as straightforward as it seems. It's incredibly easy to have resource and security leaks. Pooling, lifetime tracking, aggressive cleanup, bounded channel usage. It's basically a PaaS.

I should be a good citizen and raise issues in their codebases (and maybe PRs). My todo list is pretty long right now, honestly. Maybe I'll publish my stuff first so I can reference the implementation.
