mcp-stdio-guard vs mcp-wayback-machine

mcp-stdio-guard: mcp-stdio-guard is a tool that validates MCP stdio servers by catching stdout pollution and handshake failures before they affect clients. It starts the server, performs a real MCP initialize handshake, optionally sends a post-initialize request like tools/list, validates every stdout frame, and scans source for risky stdout calls. It helps ensure MCP servers conform to the stdio transport protocol.; mcp-wayback-machine: An MCP server and CLI tool for interacting with the Internet Archive's Wayback Machine. It supports full CDX search, snapshot content retrieval, screenshot listing, snapshot comparison, and optional authentication for higher SPN2 rate limits.
