Show HN: Mcproxy – Filter unused MCP tools to save context in Claude Code

I built a simple tool called mcproxy to solve a specific frustration I had with Claude Code with MCP I use Linear MCP that has so heavy context and I only use issue related tools in the MCP. So I want to opt out some tools like Antigravity. I also know about MCP Gateway services, and claude code's defer loading feature. But those are not my case. I want simple solution works in my local. (If you know more good solutions for this, let me know please!) `mcproxy` acts as a simple middleware something between your MCP client and the server. And this is just opensource work.
