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.
The graded MCP registry: live-probes every remote server in the official registry (initialize, tools/list, schema quality, latency, provenance) and publishes evidence-backed grades — searchable by agents via its own MCP endpoint at mcpqueen.com.
Plugin-based MCP server + Chrome extension that gives AI agents access to web applications through the user's authenticated browser session. 100+ plugins with a plugin SDK for building new ones.
