Smithery

https://smithery.ai/

Public directory of MCP servers, now part of Arcade.dev. Until 2026-10-31 it was also a connection layer (hosted MCP proxy, Connect, Toolbox, managed credentials, API, CLI and SDKs); those shut down that day, and verified servers' registry pages now list direct MCP URLs.
