Compared with every active server in this category in the registry. Stars count only when the publisher owns the repo.
It passed 4 of 5 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.
The registry does not list a required key, though some servers ask you to sign in on first use.
It runs in the maker’s cloud. Connect over the internet with nothing to install, but what you send passes through the maker’s servers.
The GitHub repo last changed 8 days ago, and the latest version (1.0.1) reached the registry 35 days ago.
Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. It connects by URL, so apps that accept remote MCP servers work too, such as ChatGPT Business and above.

Sign in with your Mailzzy account when Cline opens the browser. If the server shows an authentication error, remove it and add it again to restart the sign-in. Setup notes written for Cline itself are in llms-install.md.
Use the URL with Streamable HTTP transport. The server answers unauthenticated requests with 401 and a WWW-Authenticate header pointing at its protected resource metadata, so any client that follows the MCP authorization spec can discover the authorization server and register itself.
