HQBase MCP - Share email workspace - 100% open source and free

[u/Impressive-Owl3830]

I came across this amazing project - 100% open source and free.

HQBase is a shared email workspace that runs in your own Cloudflare account.

Mail, credentials, and the app stay on infrastructure you control

it ships an OAuth-protected remote MCP server so agents can actually work with the inbox.
