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.

Getting Started

Prerequisites

1. Python 3.10+
2. Ripgrep (rg): REQUIRED for full-text search. (Windows: choco install ripgrep, macOS: brew install ripgrep)
3. SQLite: Handled automatically by Python.

Configuration (v0.6.0)

Configuration is managed via Environment Variables.

1. mcp.json Structure

{
  "mcpServers": {
    "adaptive-agent-mcp": {
      "command": "uvx",
      "args": ["adaptive-agent-mcp"],
      "env": {
        "ADAPTIVE_EMBEDDING_BASE_URL": "https://api.xxx.cn/v1",
        "ADAPTIVE_EMBEDDING_API_KEY": "sk-your-xxx-key",
        "ADAPTIVE_EMBEDDING_MODEL": "Qwen/Qwen2.5-Coder-7B-Instruct",
        "ADAPTIVE_RERANK_BASE_URL": "https://api.xxx.cn/v1",
        "ADAPTIVE_RERANK_API_KEY": "sk-your-xxx-key",
        "ADAPTIVE_RERANK_MODEL": "BAAI/bge-reranker-v2-m3"
      }
    }
  }
}

Local Models:

• Ollama: Set ADAPTIVE_EMBEDDING_PROVIDER to ollama.
• LM Studio/vLLM: Set ADAPTIVE_EMBEDDING_PROVIDER to openai_compatible.
• Base URL: Set to your local endpoint (e.g., http://localhost:11434/v1 or http://localhost:1234/v1).
• API Key: Any string.

2. Environment Variables

All variables are prefixed with ADAPTIVE_.

Variable	Description	Default
ADAPTIVE_STORAGE_PATH	Storage location	~/.adaptive-agent/memory
ADAPTIVE_RIPGREP_PATH	Path to rg executable	Auto-detect
ADAPTIVE_EMBEDDING_PROVIDER	Embedding provider (openai_compatible)	openai_compatible
ADAPTIVE_EMBEDDING_BASE_URL	API Endpoint	None
ADAPTIVE_EMBEDDING_API_KEY	API Key	None
ADAPTIVE_EMBEDDING_MODEL	Embedding Model	Qwen/Qwen3-Embedding-8B
ADAPTIVE_RERANK_PROVIDER	Rerank provider (cohere_compatible)	cohere_compatible
ADAPTIVE_RERANK_BASE_URL	API Endpoint	None
ADAPTIVE_RERANK_API_KEY	API Key	None
ADAPTIVE_RERANK_MODEL	Reranker Model	Qwen/Qwen3-Reranker-8B

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
