When to use
Optimised for: Claude-Code-native + MCP-portable memory
Anti-fit: not for non-Claude-Code clients (some are MCP-portable)
Pros & cons
Pros
MCP server for Hindsight memory layer; gives any MCP agent access to Vectorize-tuned retrieval.
Cons
Newer; smaller adoption than Mem0 MCP / Graphiti MCP.
Claims & capabilities
Claude Code hooks for automatic cross-session memory.

Similar systems
Other claude code memory mechanisms in the catalog, ranked by inbound references.
- Official MCP Memory server T1
Knowledge-graph-based persistent memory MCP server — the canonical reference implementation. npx -y @modelcontextprotocol/server-memory ; configurable via MEMORY_FILE_PATH .
- Claude Code auto-memory T1
Persistent file-based memory at ~/.claude/projects/<project>/memory/ with a MEMORY.md index plus typed memory files (user / feedback / project / reference). Loaded into context across sessions.
- claude-brain T2
Claude Code plugin packaging of Memvid (see Dedicated memory layers). Wraps the Memvid .mv2 single-file store as a slash-command-installable plugin so per-project memory becomes a git-committable file inside the repo.
- Claude-CursorMemoryMCP T2
FastAPI server. RBAC + API-key auth, encryption, backup/recovery, embedding pipeline with deduplication. Only server in this list with role-based access control over pgvector.
- claude-mem T1
Hooks into Claude Code's session lifecycle; compresses tool outputs into ~500-token observations via Claude's agent SDK. SQLite + FTS5 with optional Chroma vector. "Endless Mode" compresses in-flight to extend session length. Captures what the agent did , not just what the user typed.
- claude-supermemory T2
Wraps Supermemory cloud API. Team memory shared across project members, separate from personal memories. Auto-capture on session end; per-repo config.
