Curated list

MCP servers that declare no API keys

Every server in this list declares no secret settings and no environment variables in its marketplace listing, so you can try it without creating an API key first. A declaration is what the publisher wrote, not a review: a server may still ask you to sign in once it runs, and some read their settings from a file instead. Servers need 100 GitHub stars or more to be listed.
