Sulcus is a thermodynamic memory platform whose Claude Code plugin adds hooks and MCP tools so agents can store, recall, and protect long-term context across sessions.
About
sulcus marketplace distributes claude-sulcus, a Claude Code plugin for persistent intelligent memory backed by the Sulcus API. It wires lifecycle hooks for auto-context, semantic search, file tracking, compaction awareness, and session capture plus MCP tools for full memory control. Choose it when your agent must remember preferences, decisions, and facts across sessions without naive RAG noise.
- claude-sulcus plugin with 7 lifecycle hooks
- 36 MCP tools for memory store, recall, and triggers
- Thermodynamic decay and knowledge-graph recall
- Connects to hosted Sulcus API at sulcus.ca

Is Sulcus self-hosted from this repo?
No—this repo ships clients and plugins; the server is proprietary and accessed via api.Sulcus.ca with an API key.
What does claude-Sulcus include?
Seven lifecycle hooks plus 36 MCP tools covering store, recall, compaction awareness, task capture, and memory protection.
How does recall differ from basic RAG?
Sulcus blends semantic search, heat-based decay, graph neighbors, recency, and triggers instead of naive vector retrieval alone.
