AutoLearn - Dynamic Skill Creation for AI Agents

AutoLearn

AutoLearn is a Model Context Protocol (MCP) server that lets AI agents dynamically create and reuse new skills (functional code workflows) from natural language.

Unlike static MCP servers, AutoLearn introduces a coding agent that:

• Converts reasoning traces into crystalized memory (Python functions).
• Decides automatically which workflows to crystalize.
• Updates its MCP spec dynamically so consuming agents can use new skills immediately.

The project includes a frontend demo app where users can:

• Chat with a consuming agent that uses AutoLearn.
• See auto-generated Python code for new skills.
• View the updated MCP spec in real time.
• Execute skills interactively.

Getting Started

Prerequisites

• Python 3.11+
• OpenAI API key

1. Clone the Repository

git clone https://github.com/tarkaai/autolearn.git
cd autolearn

2. Setup Backend and Frontend

python -m venv .venv
source .venv/bin/activate   # or .venv\Scripts\activate on Windows
pip install -e .   # Install in development mode

# Navigate to the frontend directory
cd frontend

# Install dependencies
npm install

3. Set up OpenAI API Key

# Option 1: Create a .env file (recommended)
cp .env.example .env
# Edit .env with your API key

# Option 2: Set environment variables directly
export OPENAI_API_KEY=your-api-key-here
export OPENAI_MODEL=gpt-4.1-mini  # Optional, default is gpt-4.1

4. Run the Demo

# Using the convenience script (loads .env automatically)
python demo.py

# Or start the frontend and backend separately
python server.py
cd frontend && npm run dev

The API will be available at http://localhost:8000

The frontend will be available at http://localhost:3000

API Endpoints

MCP Protocol (JSON-RPC 2.0)

• POST /mcp - MCP server endpoint for tools discovery and execution

REST API

• GET /health - Health check
• GET /tools - List all registered skills
• GET /skills/{skill_id} - Get specific skill details
• POST /skills/generate - Generate a new skill from natural language
• POST /skills/register - Register a generated skill
• DELETE /skills/{skill_id} - Delete a skill

WebSocket

• WS /ws - Real-time events (skill_added, skill_executed, mcp_updated)

Session Management

• GET /sessions - List chat sessions
• POST /sessions - Create new session
• GET /sessions/{id} - Get session details
• POST /sessions/{id}/messages - Add message to session

Example: MCP Client Integration

AutoLearn implements the full MCP (Model Context Protocol) specification. Here's how to use it:

1. MCP Tools Discovery

curl -X POST http://localhost:8000/mcp \
  -H "Content-Type: application/json" \
  -d '{
    "jsonrpc": "2.0",
    "method": "tools/list",
    "id": 1
  }'

2. Execute MCP Tool

curl -X POST http://localhost:8000/mcp \
  -H "Content-Type: application/json" \
  -d '{
    "jsonrpc": "2.0", 
    "method": "tools/call",
    "params": {
      "name": "circle_area",
      "arguments": {"radius": 5}
    },
    "id": 2
  }'

3. Generate New Skill via REST API

curl -X POST http://localhost:8000/skills/generate \
  -H "Content-Type: application/json" \
  -d '{"description": "Create a function that calculates the area of a circle", "name": "circle_area"}'

4. Frontend Demo

Visit http://localhost:3000 to see the full demo with:

• Chat interface showing MCP server capabilities
• Real-time skill generation and registration
• Live MCP specification updates
• Interactive skill execution with parameter forms

Testing

AutoLearn has comprehensive test coverage that drove the initial development

# Run all tests (54 total tests)
pytest

# Run with verbose output
pytest -v

# Run specific test categories
pytest tests/test_backend_basic.py    # Basic functionality (19 tests)
pytest tests/test_milestone2.py       # Skill generation (15 tests) 
pytest tests/test_milestone3*.py      # MCP integration (20 tests)

# Run tests with coverage

• Backend Core: API endpoints, database operations, error handling
• Skill Engine: OpenAI integration, code generation, skill registration
• MCP Protocol: JSON-RPC 2.0 compliance, tool discovery, execution
• WebSocket: Real-time events, connection handling

---

Environment Configuration

AutoLearn uses environment variables for configuration:

1. Create a .env file in the project root:

cp .env.example .env

2. Edit the .env file with your OpenAI API key:

OPENAI_API_KEY=sk-your-api-key-here

3. Optional settings:

# Choose a different OpenAI model
OPENAI_MODEL=gpt-4.1-mini

# Set logging level
LOG_LEVEL=DEBUG

# Customize database path (default is skills.db in project root)
DB_PATH=/path/to/custom/skills.db

The server.py script automatically loads variables from the .env file when starting the server.

Security Considerations

Current Implementation:

• Skills execute with direct Python execution and comprehensive error handling
• Input validation on all API endpoints with Pydantic schema validation
• WebSocket connections properly managed with graceful disconnection handling
• SQLite database operations use parameterized queries to prevent injection

Planned Security Enhancements:

• Process isolation for skill execution with resource limits (CPU, memory, time)
• Enhanced sandboxing with restricted Python environment
• Rate limiting for skill generation and execution requests
• Audit logging for all skill operations and user interactions

Development Guidelines:

• All generated skills include proper error handling and input validation
• OpenAI API calls are rate-limited and include retry logic
• Database connections use connection pooling with proper cleanup

Persistence

AutoLearn uses SQLite for persistent storage of skills:

• Skills are automatically saved to a database file (skills.db by default)
• All registered skills are restored when the server restarts
• Skills persist their metadata, source code, and other attributes
• You can customize the database path using the DB_PATH environment variable

This ensures that:

1. Skills you create are not lost when the server restarts
2. Your AI assistant can build on previously created skills
3. You can back up or version control your skills database
