Ombre Brain is a long-term emotional memory system for Claude and other MCP clients, exposing 16 MCP tools over a single /mcp connector. Memories are tagged with Russell valence/arousal coordinates, stored as Obsidian-compatible Markdown with YAML frontmatter, retrieved via hybrid keyword (rapidfuzz + BM25) and vector semantic search, and decayed by an improved Ebbinghaus forgetting curve.

Use cases

• give Claude persistent memory across conversations
• store chat memories with emotional valence and arousal coordinates
• search past memories with hybrid keyword and vector semantic retrieval
• let old memories naturally decay and archive with a forgetting curve
• import ChatGPT, Claude, or DeepSeek chat history into a memory store
• browse and manage memory buckets in Obsidian or a web dashboard
• expose a remote MCP memory server with OAuth 2.1 over HTTPS

When to choose

• you want an MCP-native persistent memory layer for Claude or another MCP client
• you prefer human-readable Markdown/Obsidian storage over a plain vector database
• you need emotionally weighted, decaying memories rather than static key-value recall
• you want resilient writes where embeddings are generated in a background queue without blocking persistence

When to avoid

• you need hard deletion or GDPR-style physical erasure of memories, since deletion only archives files
• you want a simple key-value or pure vector store without emotional/decay semantics
• you need a memory system for non-MCP clients without REST/API integration work
• you require a battle-tested enterprise memory solution rather than a niche community project
