AI History Ingester Daemon & MCP Server

A cross-platform service and Model Context Protocol (MCP) server that watches, ingests, indexes, and searches past chat sessions, agent actions, implementation plans, and artifacts from local AI coding tools (Antigravity IDE, Antigravity CLI, Claude Code, Windsurf, OpenCode, Codex, ChatGPT/Claude exports).

Architecture & Features

1. Local Disk Recovery (antigravity-local tool):

   • Zero-dependency on external databases. Directly scans and inspects local Antigravity brain sessions (~/.gemini/antigravity-ide/brain and ~/.gemini/antigravity/brain).

   • Supports list, search, get, recover, and artifacts actions.

   • Summarizes file names, sizes, creation, and modification timestamps for artifacts before returning specific file content.

2. Vector Database Integration (Qdrant):

   • Indexes session transcripts, prompt steps, and agent tool executions into a Qdrant vector database (ai_history).

   • Provides full-text and semantic search across past sessions and tool executions.

3. Continuous Background Watcher Daemon:

   • Incremental ingestion watching brain/ directories, keeping track of file read offsets in ~/.ai-history-ingest-offsets.json.

4. Lightweight Web Viewer:

   • Optional browser UI on port 3333 to inspect conversations and tool history.

MCP Configuration

Add the server to your MCP configuration (e.g. ~/.gemini/antigravity-ide/mcp_config.json, ~/.gemini/config/mcp_config.json, or Claude Desktop config):

{
  "mcpServers": {
    "ai-history": {
      "command": "node",
      "args": [
        "/path/to/ai-history-mcp/dist/mcp/server.js"
      ],
      "env": {
        "QDRANT_URL": "http://192.168.2.11:6333",
        "COLLECTION_NAME": "ai_history"
      }
    }
  }
}
