myco-brain manages memory for AI agents, connecting to your own Postgres database without requiring keys.

Written in MCP-native (Claude, Cursor, Windsurf).

What it reaches, and what it needs
What it connects to
Unverified means a mention in the server’s own description, not a citation. A wrong claim here costs nothing to correct and nothing to trust yet.
Maintenance
Shared, source-backed memory for AI agents on your own Postgres. One command wires Claude Code and Codex to recall before every prompt; Cursor, Windsurf and Claude Desktop get it over MCP. Facts keep their source, supersede instead of overwrite, and clients stay apart. Keyless. Apache-2.0.
