Persistent long-term memory for Claude Code via MCP — captures coding decisions, bugfixes, and context across sessions. Hybrid FTS5 + TF-IDF search with episode batching. Single SQLite DB, no external services. Alternative to claude-mem with 600x lower cost.
Drift inferred · capture-to-capture
No drift recorded — single capability capture; advisories appear once its surface changes.

-
mem_defer
Mark work for a future session (v2.70+). First-class carry-forward signal, surfaced in SessionStart ### Deferred Work block.
-
mem_defer_drop
Drop a deferred item without fixing it; requires a reason for the audit trail.
-
mem_defer_list
List open deferred items for the current project.

mem_get
Retrieve full details for specific observation IDs (includes importance and related_ids).
-
mem_maintain
claude-mem-lite maintain --action scan
-
mem_optimize
claude-mem-lite optimize --action preview
-
mem_recall
Recall observations related to a file. Use before editing to surface past bugfixes and context.
-
mem_recent
Show most recent observations, ordered by time. Quick snapshot of latest activity.
-
mem_registry
claude-mem-lite registry <action>
-
mem_save
Manually save a memory/observation. Accepts closes_deferred array for transactional closure of deferred work.
-
mem_search
FTS5 full-text search with BM25 ranking. Filters by type, project, date range, importance level.
-
