pythermoai 0.1.1

PyThermoAI is a Python package that leverages intelligent agents to search the web for thermodynamic data and equations, and seamlessly integrates the results into PyThermoDB.

PyThermoAI

🚀 Introduction

PyThermoAI is an intelligent Python package that revolutionizes thermodynamic data acquisition and processing by leveraging advanced AI agents and web search capabilities. This powerful tool seamlessly integrates thermodynamic data retrieval, equation solving, and database management into a unified platform.

Built with LangGraph for creating sophisticated multi-agent workflows, PyThermoAI employs intelligent agents that can reason, plan, and execute complex thermodynamic tasks. The system utilizes Tavily as its primary web search engine, enabling agents to efficiently discover and retrieve thermodynamic data from authoritative online sources.

Key Features

• 🤖 AI-Powered Data Agents: Intelligent agents that automatically search and retrieve thermodynamic properties from authoritative sources (NIST, DIPPR, peer-reviewed literature)
• 💾 Database Integration: Direct connection with PyThermoDB for data storage and management, with automatic conversion of retrieved thermodynamic data into the valid PyThermoDB format

Architecture Overview

PyThermoAI consists of several interconnected components:

• Data Agent: Searches and validates thermodynamic properties
• Equations Agent: Solves complex thermodynamic equations
• MCP Manager: Handles Model Context Protocol integrations allows using multiple MCP servers for enhanced functionality

📦 Installation

Install PyThermoAI using pip:

pip install pythermoai

Requirements

• Python 3.13+
• API keys for LLM providers (OpenAI, Anthropic, Google, etc.)
• Tavily API key for enhanced web search capabilities

🛠️ Quick Start

1. Launch the Web Interface

from pythermoai import thermo_chat

# mcp source configuration
mcp_source = {
    "tavily-remote": {
        "command": "npx",
        "args": [
            "-y",
            "mcp-remote",
            f"https://mcp.tavily.com/mcp/?tavilyApiKey={os.getenv('TAVILY_API_KEY')}"
        ],
        "transport": "stdio",
        "env": {}
    }
}

# Launch with OpenAI GPT-4
thermo_chat(
    model_provider="openai",
    model_name="gpt-4o-mini",
    mcp_source=mcp_source,
)

2. Create an AI Agent

import asyncio
from pythermoai.agents import create_agent
from pythermoai.memory import generate_thread

async def main():
    # Create a thermodynamic data agent
    agent = await create_agent(
        model_provider="openai",
        model_name="gpt-4o-mini",
        agent_name="data-agent",
        agent_prompt="You are a thermodynamic data expert...",
        mcp_source=mcp_source
    )

    # Generate conversation thread
    config = generate_thread()

    # Query for thermodynamic properties
    result = await agent.ainvoke({
        "messages": ["Find critical properties for methane"]
    }, config=config)

    print(result)

asyncio.run(main())

3. Create a FastAPI Service

from pythermoai.api import create_api
import uvicorn

# Create API with integrated agents
app = create_api(
    model_provider="openai",
    model_name="gpt-4o-mini",
    mcp_source=mcp_source
)

# Run the server
uvicorn.run(app, host="127.0.0.1", port=8000)

📋 Examples

Retrieve Thermodynamic Properties

# Request critical properties for multiple compounds
query = """
Find the following properties for methane, ethane, and propane:
- Critical Temperature (K)
- Critical Pressure (MPa)
- Critical Volume (m³/mol)
- Molecular Weight (g/mol)
"""

# The agent will automatically search, validate, and format the data
# Output will be structured in YAML format for easy integration

Convert Data to PyThermoDB Format

query = """
These are thermodynamic data for Methane
