MCP Hey Overview

Sealjay/mcp-hey MCP server gives MCP clients local read/write access to a Hey.com inbox through reverse-engineered web endpoints. A Bun/TypeScript process communicates over stdio, while a Python webview helper captures Hey session cookies during login. Messages and search data are cached in a local SQLite database, and write requests obtain fresh CSRF tokens. Reach for it when an agent needs to inspect or manage Hey mail without exposing a network listener or using a cloud relay.
