## AI overview

The author describes extending a self-hosted memory service to the Claude app through a remote MCP server. The design keeps the data at home while exposing an HTTPS endpoint through Tailscale Funnel and protecting it with OAuth 2.1, including PKCE and refresh tokens; Qdrant is also part of the setup.

## Source excerpt

I gave the Claude phone app access to my self-hosted memory -- a remote MCP server over Tailscale Funnel, OAuth and Qdrant, running on a solar-powered PC at home.
