Configure database, model, embedding, and optional Redis settings.

MemoGrafter resolves database and Studio settings from CLI flags, environment variables, and generated config.

Environment variables

.env

# MemoGrafter stores graph memory in PostgreSQL.
DATABASE_URL=postgres://postgres:postgres@localhost:5432/memo_grafter
# Add only the providers your adapters use.
OPENAI_API_KEY=sk-...
ANTHROPIC_API_KEY=sk-ant-...
GEMINI_API_KEY=...
# Required only for queue mode or recall caching.
REDIS_URL=redis://localhost:6379

Resolution order

Studio and migration use --db first.

Then .env or DATABASE_URL.

Then src/memo-grafter/mg.config.ts.

The generated config can enable Studio Prompt Preview when OPENAI_API_KEY is set.
