No install snippet on purpose. A working MCP config is a command, its arguments and an environment block — the last two are where API keys live, so this catalogue never stores them and cannot publish them. Follow the link above for the authors' own instructions.
Winnr provides 55 tools covering the full email infrastructure lifecycle. Winnr enables domain management including search, purchase, and DNS verification. Winnr allows creating email accounts in bulk or one-by-one.
Winnr supports reading, sending, and managing emails across all accounts. Winnr offers email warming with enable, pause, resume, and health monitoring. The Winnr MCP server is open source and free under the MIT license.
Winnr requires a paid plan starting at $69 per month for mailboxes and domains.
