MemoryTool

A native macOS app that provides persistent, cross-session memory for AI assistants.
Tell Claude something once — every future session knows it.

What It Does

MemoryTool combines a SwiftUI GUI for human management with an embedded MCP server that AI tools (Claude Code, Claude Desktop) use to store and retrieve memories via stdio transport.

Features

Core

6 MCP Tools: remember, recall, forget, update_memory, list_categories, get_memory
Native macOS GUI: Three-column NavigationSplitView — categories, memory list, detail editor
Multi-Process Safe: GUI and MCP server share one SQLite file via WAL mode
Tags & Categories: Flexible organization with many-to-many tag relationships
Import/Export: JSON and Markdown export for backup and portability
One-Click Install: ./install.sh builds, installs, and configures Claude Code automatically

Search (V1.1)

Hybrid Search: Combines FTS5 keyword matching with semantic vector similarity
Semantic Embeddings: Apple NLContextualEmbedding (system BERT, 768-dim, zero external dependencies)
CJK Full-Text: FTS5 trigram tokenizer — supports Chinese, English, Japanese, Korean
Weighted Ranking: Four-factor scoring — keyword relevance + semantic similarity + recency decay (30-day half-life) + access frequency

Intelligence (V1.1)

Semantic Deduplication: Cosine similarity > 0.85 detects paraphrases (e.g. "我爱吃火锅" vs "用户爱吃火锅") and merges content automatically
Access Tracking: Records access count and last accessed time for ranking
Orphan Cleanup: Deleting a memory automatically removes unused tags

Requirements

macOS 15.0+ (Sequoia)
Xcode 16+ / Swift 6.0+
Claude Code (for MCP integration)

Quick Start

Option 1: One-Click Install

git clone https://github.com/yuanyunfan/MemoryTool.git
cd MemoryTool
./install.sh

This builds the MCP server, symlinks it to ~/.memorytool/bin/, and configures Claude Code automatically.

Option 2: Manual Setup

Build:

swift build -c release --product MemoryMCP

Install binary:

mkdir -p ~/.memorytool/bin
ln -sf "$(pwd)/.build/release/MemoryMCP" ~/.memorytool/bin/MemoryMCP

Configure Claude Code — add to ~/.claude/settings.json under mcpServers:
