Buttondown

Buttondown MCP Server provides a TypeScript-based interface for interacting with the Buttondown newsletter API, enabling AI assistants to manage email campaigns through four core tools: listing emails with status filtering, creating drafts, retrieving analytics, and scheduling publications. The implementation features secure API key handling with 1Password integration, comprehensive parameter validation using Zod, and optimized scheduling support with ISO 8601 datetime formatting. Built with a test-driven approach, it's particularly valuable for automating newsletter workflows, analyzing campaign performance, and managing publication schedules without leaving the conversation interface.
