未认领Open-source MCP memory server. Universal AI memory across all platforms.
安装
claude mcp add hippocampus --transport http http://localhost:3000/mcp工具（11 个）
check_version
"Did anything change?" — pass an entity name + cached hash, get back yes/no. No embedding computation, pure metadata.
consolidate
Find clusters of similar/duplicate memories, detect near-duplicate entities, surface contradictions, or run sleep mode for batch lifecycle analysis (compress/prune/refresh)
context
Get everything about a topic — observations, relationships, related entities. Includes versionhash.
export
Export as CLAUDE.md context file, readable markdown, JSON, wire format, or Obsidian vault
forget
Permanently delete a memory or entity (secure deletion)
merge
Merge multiple observations into one (atomic consolidation). Returns versionhash.
merge_entities
Merge multiple entities into one — moves all data, deletes sources. Returns versionhash.
onboard
Bootstrap memory from a new AI session. Returns structured extraction instructions the AI follows to capture user context.
recall
Search memories by semantic similarity + keyword match. Filter by type, kind, since. Use spread: true to follow relationships and discover connected memories. Includes versionhash per entity in all formats.
remember
Store a fact, preference, or piece of context. Optional kind classification (fact, decision, question, preference, or custom) and importance weighting. Reports overlapping observations so the AI can consolidate incrementally. Returns versionhash for cache invalidation.
update
Replace an existing observation with new content. Returns versionhash.
