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.
Mount many OpenAPI specs (or your existing FastAPI app) as MCP servers in one process. Auto-promotes eligible GETs to MCP resources, exposes huge specs via three list/get/call meta-tools instead of N tool schemas, and ships per-user OAuth2 token relay with audience-bound tokens.
MCPX is a production-ready, open-source gateway to manage MCP servers at scale—centralize tool discovery, access controls, call prioritization, and usage tracking to simplify agent workflows.
