Self-Evolving RAG for AI Agents — A cross-app persistent memory system where agents autonomously write, retrieve, and evolve their knowledge

Self-Evolving RAG for AI Agents

Agents don't just read memory — they write it.

中文 | English

Core Concept

Traditional RAG User Input → Retrieve KB → Generate ↑ Read-only (Human-maintained)

Self-Evolving RAG User Input → Retrieve Memory → Generate ↑↓ Read + Write Agent autonomously evolves

Key Differences:

	Traditional RAG	Adaptive Agent MCP
Read	Retrieves pre-indexed documents	Dynamically accumulates at runtime
Write	Human-maintained knowledge base	Agent writes autonomously
Scope	Generic knowledge	User-specific memory
State	Static data	Continuously evolves

How It Works

In Claude Code: "Remember, I prefer TypeScript"
         ↓
    Agent automatically calls:
    • append_daily_log() → Record to daily log
    • update_preference() → Update preferences
    • extract_knowledge() → Extract knowledge graph
         ↓
In Antigravity: "What are my coding preferences?"
         ↓
    AI: "You prefer TypeScript"

Teach once, remember forever. Share across apps, never forget.

Quick Start

Installation

Configure mcp.json in any MCP-compatible AI application:

Basic Configuration:

{
  "mcpServers": {
    "adaptive-agent-mcp": {
      "command": "uvx",
      "args": ["adaptive-agent-mcp"]
    }
  }
}

Full Configuration (with Semantic Search API):

{
  "mcpServers": {
    "adaptive-agent-mcp": {
      "command": "uvx",
      "args": ["adaptive-agent-mcp"],
      "env": {
        "ADAPTIVE_EMBEDDING_BASE_URL": "https://api.openai.com/v1",
        "ADAPTIVE_EMBEDDING_API_KEY": "your-api-key",
        "ADAPTIVE_EMBEDDING_MODEL": "text-embedding-3-small",
        "ADAPTIVE_RERANK_BASE_URL": "https://api.cohere.ai/v1",
        "ADAPTIVE_RERANK_API_KEY": "your-api-key",
        "ADAPTIVE_RERANK_MODEL": "rerank-english-v3.0"
      }
    }
  }
}

Default storage path: ~/.adaptive-agent/memory. All apps share the same memory.

Enhance Agent Memory Behavior (Optional)

If your AI doesn't actively read/write memory, add this to your system prompt or user rules:

## Memory System Instructions

- At the start of each conversation, call `initialize_session` to load user preferences.
- When user says "remember", "save", or expresses preferences, call `update_preference` or `append_daily_log`.
- After completing tasks, briefly record progress using `append_daily_log`.
- When user asks about past conversations, use `query_memory_headers` or `search_memory_content`.

Data Safety

• Isolated storage: Data stored in ~/.adaptive-agent/memory, independent of uvx installation
• Concurrent safety: filelock prevents data corruption from multiple clients
• Human-readable: All data in Markdown/JSON format, easy to backup and version control
