AssistMem

What it does

AssistMem indexes all your local AI chat history from Cursor IDE, VS Code Copilot, Claude Code, Codex CLI, and Gemini CLI into a single SQLite database with full-text search. It then exposes that index as an MCP server, so any AI assistant can query your past conversations for context — letting Claude, Codex, or Cursor recall what you've discussed across different tools and sessions.

All data stays on your machine. No cloud sync, no accounts, no telemetry.

Tools

• search_chat_history — Full-text keyword search across all indexed AI chat sessions. Returns matching messages with source, session ID, and timestamp.
• list_sources — List all indexed sources (Cursor, Copilot, Claude Code, Codex, Gemini CLI) with message counts.
• get_session — Retrieve all messages from a specific past chat session by ID.

Installation

Add to your claude_desktop_config.json:

{
  "mcpServers": {
    "assistmem": {
      "command": "npx",
      "args": ["assistmem", "mcp", "--client", "claude-desktop"]
    }
  }
}

For other clients, replace --client claude-desktop with the appropriate client name (e.g. cursor, codex, gemini-cli).

A desktop app (macOS .dmg) is also available from the Releases page for a GUI indexing experience.
