Editorial EvaluationMcpsnoop vs Astro: compare documented features, pricing, and pros/cons below — the best choice depends on your primary workflow.
Choose Mcpsnoop if: Free (Open Source, MIT)
Mcpsnoop is a transparent proxy and live terminal UI that acts as 'Wireshark for MCP.' It sits in the real data path between your AI client (Cursor, Claude Code, Codex) and your MCP servers, capturing every JSON-RPC frame — tool calls, arguments, responses, stderr — as they actually happen. Unlike the official MCP Inspector, which connects as a second client off to the side, Mcpsnoop sees exactly what your real client and server say to each other, including calls the model never made or made with wrong arguments. It flags slow and hung calls, surfaces invalid frames, supports replay, capability inspection, and session export (JSON/HTML/text/OTLP), and runs as a single dependency-free binary (Go, MIT licensed).
Choose Astro if: Free / Open Source
Web developers and technical publishers building high-performance, content-driven websites with zero client-side JavaScript by default.
