Side-by-side comparison of two Model Context Protocol servers — install paths, tools, quality signals, and directory engagement so you can pick the right one for Claude, Cursor, and other MCP clients.
MCP stdio interceptor (@jamjet/mcp-shim) that applies one YAML policy file (block / requireapproval / audit / budget cap) to tools/call requests before they reach the real MCP server.

URL fetcher and HTML-to-markdown converter with three-layer prompt injection defense: pre-extraction sanitization of hidden/off-screen elements and non-printing Unicode, 15-pattern risk scanning (HIGH/MEDIUM/OK), and per-request session-salt content boundary wrapping.
