# Unforget MCP Server Long-term memory for Claude Code, Cursor, and any MCP client. Zero LLM on write. Zero config. ## Install ```bash pipx install unforget-mcp --python python3.12 ``` ## Setup ### Claude Code Add to your project's `.mcp.json` or global settings: ```json { "mcpServers": { "unforget": { "command": "unforget-mcp", "args": [] } } } ``` ### Cursor Add to Cursor settings → MCP Servers: ```json { "mcpServers": { "unforget": { "command": "unforget-mcp", "args": [] } } } ``` ### VS Code (Copilot) Add to `.vscode/mcp.json`: ```json { "mcpServers": { "unforget": { "command": "unforget-mcp", "args": [] } } } ``` That's it. No API keys, no Docker, no database setup. An embedded PostgreSQL starts automatically. ## Tools | Tool | Description | |------|-------------| | `memory_store` | Store a fact, preference, or decision | | `memory_search` | Search memories with 4-channel retrieval | | `memory_forget` | Delete memories by query or ID | | `memory_list` | List all stored memories | | `memory_update` | Update a memory (preserves history) | ## Options ```bash # Embedded mode (default — auto-starts PostgreSQL) unforget-mcp # External database unforget-mcp --database-url postgresql://user:pass@localhost/db # Custom scoping unforget-mcp --org-id myorg --agent-id myagent # SSE transport (for remote connections) unforget-mcp --transport sse --port 8767 ``` ## How It Works ``` Claude Code / Cursor / MCP Client │ MCP protocol (stdio or SSE) ▼ unforget-mcp server ├── unforget core (4-channel retrieval, embedder, reranker) └── pgserver (embedded PostgreSQL + pgvector) ``` - Memories persist in `~/.unforget/mcp-data/` - 4-channel retrieval: semantic + BM25 + entity + temporal - Cross-encoder reranking for accuracy - Zero LLM calls on write (~7ms per memory) ## License Apache 2.0
