Reletter is a Model Context Protocol (MCP) server: Search and analyze 7M+ newsletters, issues, contacts, and chart rankings from Reletter. Because it speaks the Model Context Protocol, AI assistants can use Reletter as a set of callable tools instead of you copy-pasting between apps.
It's a hosted (remote) server — point your client at https://mcp.reletter.com and you're connected, with nothing to install locally. The current release is v0.1.0, published under the MIT license, with source at getreletter/reletter-mcp on GitHub.
On mcp.site, Reletter sits in the Marketing category. Any MCP client can use it — Claude Desktop, Claude Code, Cursor, VS Code, Windsurf, Zed among them — via the install snippets below.
