# Claude Memory Manager

**Cross-session memory for Claude Code** — never lose context between sessions.

Claude Memory Manager automatically captures architectural decisions, code changes, bug fixes, and configuration choices from your Claude Code sessions, then intelligently retrieves relevant context when you start new sessions.

## What It Does

Every time you use Claude Code, valuable context is created and lost when the session ends:
- Which libraries you chose and why
- Bug fixes and their root causes
- Configuration decisions
- File structure and naming conventions
- Error resolutions

Claude Memory Manager solves this by:
1. **Parsing** your Claude Code session logs (JSONL files)
2. **Extracting** meaningful memories with importance scoring
3. **Embedding** memories for semantic search
4. **Storing** everything in a local SQLite database with FTS5
5. **Retrieving** relevant context via hybrid semantic + keyword search
6. **Serving** context to Claude Desktop via MCP protocol

## Installation

```bash
pip install claude-memory-manager
```

For local embeddings (no API key needed):
```bash
pip install claude-memory-manager[local]
```

For development:
```bash
pip install claude-memory-manager[dev]
```

## Quick Start

### 1. Initialize the Database

```bash
claude-memory init
```

This creates the SQLite database at `~/.claude-memory/memory.db` and saves a config file.

### 2. Ingest Session Logs

```bash
# Ingest all sessions from the default path (~/.claude/projects/)
claude-memory ingest

# Ingest from a specific path
claude-memory ingest /path/to/sessions

# Watch for new sessions and auto-ingest
claude-memory ingest --watch
```

### 3. Search Memories

```bash
# Search across all memories
claude-memory search "authentication setup"

# Filter by project
claude-memory search "database schema" --project /path/to/project

# Filter by category
claude-memory search "cors" --category config
```

### 4. Generate Context Summary

```bash
# List all indexed projects
claude-memory context

# Generate summary for a specific project
claude-memory context /path/to/project

# With custom token limit
claude-memory context /path/to/project --max-tokens 3000
```

### 5. Connect to Claude Desktop (MCP)

Add to your Claude Desktop config (see [MCP Setup](#mcp-setup)):

```json
{
  "mcpServers": {
    "claude-memory": {
      "command": "claude-memory-mcp",
      "args": []
    }
  }
}
```

## MCP Setup

### Claude Desktop

1. Find your Claude Desktop config file:
   - **macOS:** `~/Library/Application Support/Claude/claude_desktop_config.json`
   - **Windows:** `%APPDATA%\Claude\claude_desktop_config.json`

2. Add the memory server:

```json
{
  "mcpServers": {
    "claude-memory": {
      "command": "claude-memory-mcp",
      "args": []
    }
  }
}
```

3. Restart Claude Desktop.

See `examples/claude-desktop-config.json` for a complete example.

### MCP Tools

Once connected, Claude Desktop can use these tools:

| Tool | Description |
|------|-------------|
| `memory_search` | Search memories by query with optional filters |
| `memory_recall` | Get a formatted context summary for a project |
| `memory_save` | Save a new memory directly |
| `memory_stats` | Get database statistics |

### Data Flow

```
Session Logs (.jsonl)
        |
  [JSONL Parser] -----> ParsedSession
        |
  [Extractor] --------> Memory objects (categorized, scored)
        |
  [Embedder] ----------> Embeddings (bytes for SQLite BLOB)
        |
  [Indexer] -----------> SQLite DB (with FTS5 index)
        |
  [Retriever] ---------> Search results (hybrid ranked)
        |
  [Summarizer] --------> Context summary (markdown)
```

## Configuration

Configuration is loaded from (in priority order):
1. Environment variables
2. Config file (`~/.claude-memory/config.json`)
3. Defaults

### Environment Variables

| Variable | Description | Default |
|----------|-------------|---------|
| `CLAUDE_SESSIONS_PATH` | Path to session logs | `~/.claude/projects` |
| `CLAUDE_MEMORY_DB_PATH` | Database file path | `~/.claude-memory/memory.db` |
| `CLAUDE_MEMORY_EMBEDDING_PROVIDER` | `anthropic`, `voyage`, or `local` | `local` |
| `ANTHROPIC_API_KEY` | Anthropic API key | — |
| `VOYAGE_API_KEY` | Voyage AI API key | — |
| `CLAUDE_MEMORY_MAX_TOKENS` | Max tokens for context | `2000` |
| `CLAUDE_MEMORY_LOG_LEVEL` | Log level | `INFO` |

### Embedding Providers

| Provider | Dimension | Requires |
|----------|-----------|----------|
| `voyage` | 1024 | `VOYAGE_API_KEY` |
| `anthropic` | 1024 | `ANTHROPIC_API_KEY` |
| `local` | 384 | `pip install claude-memory-manager[local]` |

If no provider is available, a stub provider is used (keyword search still works, but semantic search is disabled).

## FAQ

**Where are my memories stored?**
In a SQLite database at `~/.claude-memory/memory.db`. All data stays local.

**Does this send my code to any API?**
Only if you configure the Voyage or Anthropic embedding provider. In that case, only memory text content (not full session logs) is sent to generate embeddings. Use `local` for fully offline operation.

**How does deduplication work?**
Each memory's content is hashed (SHA-256). If a memory with the same hash already exists, it is skipped during ingestion.

**How does hybrid search work?**
Results from cosine-similarity vector search (70% weight) are combined with SQLite FTS5 keyword search results (30% weight). Memories appearing in both get combined scores.

**Can I export my memories?**
Yes: `claude-memory export > memories.json` or `claude-memory export -o file.json`.

**How do I prune old memories?**
`claude-memory prune --older-than 90d` removes memories older than 90 days. Supports `d` (days), `w` (weeks), `m` (months), `y` (years).
