Anthropic lets you export your Claude conversation history but provides no way to import it into a new account. This is a local MCP server that makes the export actually useful — index your old conversations into SQLite and Claude can search them automatically in new sessions.

**Background:** [Claude lets you export your data but won't let you use it](https://sawinyh.com/blog/claude-export-no-import)

Why

If you switch Claude accounts, lose access to an email address, or just want your old context available going forward, you're stuck with a JSON file you can't do anything with. This tool indexes that file and exposes it as three MCP tools Claude calls automatically during conversations.

Setup

**1. Export your Claude history**

Go to claude.ai → Settings → Export Data. You'll get a ZIP containing `conversations.json`.

**2. Install dependencies**

git clone https://github.com/sneg55/old-claude-mcp
cd old-claude-mcp
pip install -r requirements.txt

**3. Index your export**

python indexer.py ~/Downloads/conversations.json --db history.db

**4. Add to Claude Desktop config**

Edit `~/Library/Application Support/Claude/claude_desktop_config.json`:

{
  "mcpServers": {
    "chat-history": {
      "command": "/usr/local/bin/python3",
      "args": [
        "/path/to/old-claude-mcp/server.py",
        "--db",
        "/path/to/old-claude-mcp/history.db"
      ]
    }
  }
}

Use an absolute path to your Python interpreter. Find it with `which python3`.

**5. Rest
