Lorekeeper

What it does

Lorekeeper is a local MCP server that provides agents with persistent, self-improving memory. It uses a hybrid search pipeline (semantic vectors + BM25) and a quality loop where useful memories are reinforced and irrelevant ones decay over time.

Tools

• lore_search: Hybrid semantic and keyword search for retrieving context.
• lore_remember: Fast one-shot memory saving with auto-titling.
• lore_update: Provide feedback on memory utility to improve future retrieval.
• lore_reflect: Extracts learnings from a session and saves them as discoveries.
• lore_forget: Soft-delete outdated or incorrect memories.
• lore_insert: Bulk structured memory insertion.
• lore_recommend_links: Suggests connections between related memories.
• lore_processed_sessions: Tracks which sessions have been archived.

pip install lorekeeper-mcp && lorekeeper setup
