Smithery
MCP registry + hosting platform
Free tier + paidMCP servers & registriessmithery.ai
What it is
The largest MCP marketplace, advertising 15,190+ servers with generated config for Claude Code, Cursor and other clients. It is also a host: you can deploy servers to Smithery over streamable HTTP, and it manages auth, credentials and sessions for you. Its homepage states Smithery is now part of Arcade.dev.
Why it earns a slot
The fastest path from 'I need a Notion tool' to a working config. It generates the client snippet and runs the OAuth handshake so you never hand-edit a JSON config file.
Know before you commit
Listing volume is not curation — most of those 15,000 entries are unvetted community code. Using hosted connections also means your access tokens live in a third party's vault.
Getting started
npx smithery auth login, then copy the generated config from the server's page
Neighbourhood
How Smithery sits against the rest of the atlas — swaps, companions and the tools builders actually save alongside it.
