Overview

This is a simple demo MCP HTTP server. You can use it with claude.ai or other compatible MCP clients.

You need protect its access using Pomerium. Currently you need to use main branch.

Config

Note that you do need to set up database persistence, to keep client registrations etc.

Note that you need pass a domain name as in the from of the route.
