dejadb

Command-line interface for DejaDB, the embedded memory engine for AI agents.

dejadb builds the deja binary — a thin shell over the store and CAL layers where one memory is one file. It offers verbs for the full lifecycle: adding grains, structural and hybrid recall, running CAL queries, inspecting history and the op-log, moving data with bundles, streaming, and restore, and migrating in from other memory systems (deja migrate — mem0, Zep, Letta, LangMem, Basic Memory, generic JSONL). It also drives the MCP server and the local web console, so it is the primary hands-on entry point to a DejaDB memory.

# add a fact, then recall it as model-ready context
deja add    --db demo.db --ns caller --subject john --relation prefers --object tea
deja recall --db demo.db --ns caller --subject john --render sml
