OB1 (Open Brain) is a TypeScript agent app that positions itself as infrastructure for personal thinking: a single database, AI gateway, and chat channel that any AI can plug into, with no middleware or SaaS dependency. It ships agent configuration files (AGENTS.md, CLAUDE.md, .claude directory) and its topics indicate an MCP-based memory layer built on Supabase for personal knowledge management.

You want one self-hosted memory and knowledge layer that any AI agent can connect to via MCP, without depending on hosted SaaS.

Use it to

  • Store personal knowledge in a single database accessible to AI agents
  • Expose a memory layer to agents over MCP
  • Route AI interactions through one gateway and chat channel
  • Configure agents using the shipped AGENTS.md and CLAUDE.md files

For Developers building personal AI agent setups with MCP
