I work with JSON-RPC and OpenRPC a lot and this was a much needed missing tool in my toolset. So I put together this JSON-RPC Debugger.
Pause, inspect, and modify every call in real-time.
Built in rust /w ratatui, inspired by proxyfor, lazyvim and Charles Proxy.
I'm getting a lot of use out of it debugging Ethereum and even MCP server JSON-RPC calls.
