Indie product Reletter has launched a hosted MCP (Model Context Protocol) server, unlocking its database of over 7 million newsletters across Substack, LinkedIn, Ghost, and more.
By connecting to the server, users can leverage this data directly within AI clients like ChatGPT, Claude, or Cursor to:
- Search and filter newsletters by topic, audience size, or platform.
- Extract contacts, social accounts, and engagement metrics.
- Find mentions of specific brands or keywords across indexed issues.
The developer has also open-sourced the project, providing a powerful automation tool for content creators and marketers.
