CLAUDE DUET IS A RESEARCH PREVIEW. THESE 10 REPOS WORK TONIGHT everyone is refreshing for Duet access while the pieces to build your own sit on GitHub with over 600,000 stars between them 10 GitHub repositories to build the same thing on Claude Code: 01 MCP Servers → give Claude Code hands through official connectors for files, git and the web, so your agent can read the places your work actually lives http://github.com/modelcontextprotocol/servers 02 Basic Memory → keep everything Claude learns in plain Markdown files it can search and update, so you never re-explain a project again http://github.com/basicmachines-co/basic-memory 03 Mem0 → add a memory layer that keeps your preferences, people and past decisions across sessions, so every brief starts from what it already knows http://github.com/mem0ai/mem0 04 Graphiti → track how facts change over time, so your agent knows the deadline moved instead of quoting the old one http://github.com/getzep/graphiti 05 n8n → schedule the morning brief, trigger your agent when an email lands and route its drafts back to you for approval http://github.com/n8n-io/n8n 06 Huginn → run agents that watch sites, feeds and inboxes on your behalf and only ping you when something actually changed http://github.com/huginn/huginn 07 whisper.cpp → turn voice notes into text locally, so "remind me to call the bank" from your walk ends up in tomorrow's brief http://github.com/ggml-org/whisper.cpp 08 Paperless-ngx → scan bills, contracts and letters into a searchable archive your agent checks before it reminds you of a deadline http://github.com/paperless-ngx/paperless-ngx 09 Karakeep → drop links, notes and screenshots into one inbox with auto-tagging, so your agent sorts what you saved instead of you http://github.com/karakeep-app/karakeep 10 Langfuse → trace every run your agent makes while you're away, so you can see exactly what it read, what it drafted and why http://github.com/langfuse/langfuse start with memory and one connector. a morning brief that knows your people beats ten automations that don't then add the schedule. once it runs at 7am without you, put "ask before acting" in place before you connect anything that can send memory → connectors → schedule → approvals. that's the whole Duet idea, built from parts you can inspect how to wire all 10 together ↓
