+# waggle-memory-mcp
+
+Persistent memory MCP server for **Claude Code**, **Claude Desktop**, and any MCP-compatible AI system.
+
+Give your AI assistant memory that persists across conversations — facts, decisions, preferences, project context, and a knowledge graph of entities and relationships.
+
+Powered by the [Waggle OS](https://waggle-os.ai) memory engine.
+
+## Features
+
+- **Persistent Memory** — Save and recall facts, decisions, preferences across conversations
+- **Semantic Search** — Hybrid FTS5 keyword + sqlite-vec vector search with RRF fusion
+- **Knowledge Graph** — Entities (people, projects, concepts) and their relationships
+- **Identity** — Persistent user profile (name, role, capabilities)
+- **Awareness** — Short-lived context markers for active tasks and flags
+- **Workspaces** — Isolated memory spaces for different projects
+- **Harvest** — Import conversation history from ChatGPT, Claude, Gemini, and more
+- **Zero Config Embeddings** — Offline vector search using a local ONNX model (23MB, auto-downloaded)
+- **Shared Data** — Same `~/.waggle/` directory as Waggle OS desktop app
+
+## Installation
+
+### Claude Code
+
+Add to `~/.claude/settings.json`:
+
+```json
+{
+  "mcpServers": {
+    "waggle-memory": {
+      "command": "npx",
+      "args": ["-y", "waggle-memory-mcp"]
+    }
+  }
+}
+```
+
+### Claude Desktop
+
+Add to `~/.claude/claude_desktop_config.json`:
+
+```json
+{
+  "mcpServers": {
+    "waggle-memory": {
+      "command": "npx",
+      "args": ["-y", "waggle-memory-mcp"]
+    }
+  }
+}
+```
+
+### Custom Data Directory
+
+```json
+{
+  "mcpServers": {
+    "waggle-memory": {
+      "command": "npx",
+      "args": ["-y", "waggle-memory-mcp"],
+      "env": {
+        "WAGGLE_DATA_DIR": "/path/to/your/.waggle"
+      }
+    }
+  }
+}
+```
+
+## Tools
+
+| Tool | Description |
+|------|-------------|
+| `save_memory` | Save a memory (fact, decision, preference) with importance level |
+| `recall_memory` | Semantic search across memories with scoring profiles |
+| `search_entities` | Search the knowledge graph for entities |
+| `save_entity` | Create or update an entity in the knowledge graph |
+| `create_relation` | Create a relationship between entities |
+| `get_identity` | Get the user's persistent identity profile |
+| `set_identity` | Create or update identity (name, role, etc.) |
+| `get_awareness` | Get active tasks, pending items, context flags |
+| `set_awareness` | Set a short-lived awareness item |
+| `clear_awareness` | Remove awareness items by ID or category |
+| `list_workspaces` | List all workspaces with memory stats |
+| `create_workspace` | Create a new isolated workspace |
+| `harvest_import` | Import conversations from ChatGPT, Claude, Gemini |
+| `harvest_sources` | List registered harvest sources and sync status |
+
+## Resources
+
+| URI | Description |
+|-----|-------------|
+| `memory://personal/stats` | Frame count, entity count, embedding provider status |
+| `memory://identity` | Current identity profile |
+| `memory://awareness` | Active awareness items |
+| `memory://workspace/{id}` | Workspace config and memory stats |
+
+## Architecture
+
+```
+~/.waggle/
+├── personal.mind          ← SQLite database (WAL mode + sqlite-vec)
+├── models/                ← Cached ONNX embedding model
+├── config.json            ← Settings
+└── workspaces/
+    └── {id}/
+        ├── workspace.json ← Workspace config
+        └── workspace.mind ← Workspace SQLite database
+```
+
+### Memory Model
+
+- **I-Frame** (Identity): Base facts — "User prefers TypeScript"
+- **P-Frame** (Procedural): Updates to I-Frames
+- **B-Frame** (Bridging): Links between frames
+
+### Search Pipeline
+
+1. FTS5 keyword search (stop-word filtered, OR-based)
+2. sqlite-vec k-NN vector search (1024-dim embeddings)
+3. RRF fusion (K=60) combines both result sets
+4. Relevance scoring with 4 profiles: balanced, recent, important, connected
+
+### Embedding Provider Chain
+
+Probed in order, first success wins:
+
+1. **InProcess** — `all-MiniLM-L6-v2` ONNX model, zero config, ~23MB download
+2. **Ollama** — `nomic-embed-text` (requires local Ollama)
+3. **Voyage/OpenAI** — API-based (requires API keys)
+4. **Mock** — Deterministic fallback (always works, no semantic quality)
+
+## Environment Variables
+
+| Variable | Description | Default |
+|----------|-------------|---------|
+| `WAGGLE_DATA_DIR` | Data directory path | `~/.waggle` |
+| `WAGGLE_EMBEDDING_PROVIDER` | Force a specific provider | `auto` |
+| `WAGGLE_OLLAMA_URL` | Ollama server URL | `http://localhost:11434` |
+| `WAGGLE_OLLAMA_MODEL` | Ollama model name | `nomic-embed-text` |
+| `WAGGLE_VOYAGE_API_KEY` | Voyage AI API key | — |
+| `WAGGLE_OPENAI_API_KEY` | OpenAI API key | — |
+
+## Shared with Waggle OS
+
+If you also run [Waggle OS](https://waggle-os.ai) desktop, this MCP server shares the **same data directory**. Memories saved in Claude Code appear in Waggle OS and vice versa. SQLite WAL mode supports concurrent readers.
+
+## Development
+
+```bash
+# From the waggle-os monorepo root
+cd packages/memory-mcp
+npm install
+npm run build
+npm start
