Hippocampus

Persönliches Gedächtnis als Graph mit HTTP + MCP-Schnittstelle, Ersatz für Obsidian/Engram.

Stack: uv · Python 3.11+ · SQLModel + SQLite (FTS5) · FastAPI + FastMCP · Typer · Rich.

Start

uv sync                           # OBLIGATORIO
uv run hippocampus init <db-path> # bootstrap (crea BD + siembra)
uv run hippocampus serve          # HTTP+MCP en 127.0.0.1:27130

Unterbefehle: init, serve, mcp (stdio), graph (interaktive Karte in HTML, --tui für die Tabellenansicht), backup (SQL-Dump).

Architektur

Clean Architecture in Schichten (Abhängigkeiten → nach innen):

  • api/ — HTTP/MCP-Transport (null Logik).

  • schemas/ — API-Vertrag (Pydantic, D26).

  • core/ — Domäne (búsqueda-y-enlazar, Graph, Technik).

  • db/, models/ — Persistenz (SQLModel, FTS5, Seed).

Zwei durch Konstruktion getrennte Bereiche (ohne space-Spalte):

  1. Persönlich (Graph): Knoten → edges → documents + attachments. Ersetzt Obsidian.

  2. Technisch (Engram-style): observations mit status/type. Ersetzt Engram.

Siehe docs/sdd-hippocampus.md (vollständiges SDD) und docs/todo-hippocampus.md (Checkliste) für Details.
