This fork ships an MCP server in mcp-server/ that exposes your Memos instance to Anthropic's Claude — read, search, create, update, delete memos directly from a chat. Works across every Claude surface:

• Claude Code CLI, Claude Desktop, claude.ai web, and the Claude Android / iOS app — all four surfaces go through the same OAuth 2.1 + PKCE flow against a GitHub OAuth App, no bearer header to copy around

A single long-running HTTP service per Memos instance serves all clients. Public exposure goes through your existing Cloudflare Tunnel; the gate is the OAuth flow plus the server-side OAUTH_ALLOWED_USERS allowlist of GitHub logins. See mcp-server/README.md for setup, including the section on public exposure for cloud Claude clients.
