What makes NovaProxy different
04 / Highlights02
MCP aware
One toggle isolates Model Context Protocol traffic and renders the JSON-RPC as tool calls, arguments and results instead of a wall of framed text.
03
Rules & breakpoints
Rewrite headers, map a host to localhost, inject latency or failures — or pause a flow mid-flight and edit the request before it leaves.
04
Scriptable hooks
Attach JavaScript to request and response events for signing, redaction or assertions. No proxy restart, no rebuild.
