Hunter's comment

ProtoMCP is a browser-based playground for exploring and testing Model Context Protocol (MCP) servers. Connect to any MCP server, discover tools automatically, run them using generated forms, and inspect JSON-RPC requests and responses in real time. No curl commands. No manual payloads. Just connect and start testing. You can read more about it here: https://blogs.jaseci.org/blog/2026/03/16/building-protomcp/
