A production-ready Model Context Protocol (MCP) server that gives AI agents like Claude access to the comprehensive reservoir engineering library pyResToolbox. Now Claude can perform sophisticated PVT calculations, well performance analysis, and reservoir simulation tasks through natural conversation.

☕ Support This Project

If you find this project useful, consider buying me a coffee! Your support helps maintain and improve this open-source tool.

What is This?

This MCP server bridges the gap between AI assistants and petroleum engineering workflows. Instead of manually calculating reservoir properties or writing complex scripts, you can simply ask Claude:

"Calculate the bubble point pressure for API 35° oil at 180°F with solution GOR of 800 scf/stb and gas gravity 0.75 using the Valko-McCain correlation"

"Generate an IPR curve for my well with Pi=4000 psia, Pb=3500 psia, API 38°, 175°F, pay thickness 75 ft, permeability 150 mD"

"Create a black oil table for simulation with pressures from 500 to 5000 psia"

Claude will execute the calculations using industry-standard correlations and return accurate, formatted results.

Tips for Better Queries

Be Specific - Include all relevant parameters (API, temperature, pressure, etc.)
Specify Methods - Mention which correlation you want (VALMC, DAK, Corey, LET, etc.)
Include Units - Always specify units (psia, degF, mD, ft, etc.)
Ask for Comparisons - Request comparisons between methods or scenarios
Request Tables - Ask for tabulated results when you need multiple values

Programmatic Usage

While this server is designed for Claude Desktop integration, you can also use it programmatically:

Python Client

import asyncio
from fastmcp.client import InMemoryTransport
from pyrestoolbox_mcp import mcp

async def calculate_pvt():
    transport = InMemoryTransport(mcp)

    async with transport.get_client() as client:
        # Calculate bubble point
        pb_result = await client.call_tool(
            "oil_bubble_point",
            {
                "api": 35.0,
                "degf": 180.0,
                "rsb": 800.0,
                "sg_g": 0.75,
                "method": "VALMC"
            }
        )
        pb = pb_result['value']
        print(f"Bubble Point: {pb:.2f} psia")

        # Calculate Rs at multiple pressures
        rs_result = await client.call_tool(
            "oil_solution_gor",
            {
                "api": 35.0,
                "degf": 180.0,
                "p": [1000, 2000, 3000, pb, 4000],
                "sg_g": 0.75,
                "pb": pb,
                "rsb": 800.0,
                "method": "VELAR"
            }
        )
        print(f"Rs values: {rs_result['value']}")

        # Access configuration resources
        methods = await client.read_resource("config://methods")
        print(f"Available methods:\n{methods.content}")

asyncio.run(calculate_pvt())

HTTP/SSE Transport

# Start HTTP server
uv run fastmcp run server.py --transport http --port 8000

# Or using Docker
docker-compose --profile http up -d

Then connect using any MCP client or HTTP client supporting the MCP protocol.

Troubleshooting

Installation Issues

"uv: command not found"

Close and reopen terminal after installing UV
Verify: uv --version
Alternative: Use pip instead (pip install -e .)

"make: command not found" (Windows)

Use manual commands from Makefile
Or install Make for Windows via Chocolatey: choco install make

UV sync fails

Clear cache: rm -rf .venv && make uv-install
Check Python version: python --version (needs 3.10+)

Claude Desktop Integration

Error: "spawn uv ENOENT"

This means Claude Desktop cannot find the uv command
GUI applications don't inherit your terminal's PATH
Solution: Use absolute path to uv in your config
Find UV path: which uv (macOS/Linux) or Get-Command uv (Windows)
Common locations:
- macOS/Linux: /Users/username/.local/bin/uv or /home/username/.local/bin/uv
- Windows: C:\Users\username\.cargo\bin\uv.exe

Claude doesn't see the tools

Use absolute paths for both uv command and project directory (no ~, use full path)
Verify paths are correct: ls /path/to/uv and ls /path/to/pyrestoolbox-mcp
Completely restart Claude Desktop (Quit, not just close window)
Check Claude Desktop logs:
- macOS: ~/Library/Logs/Claude/
- Windows: %APPDATA%\Claude\logs\
- Linux: ~/.config/Claude/logs/
Test server manually: cd /path/to/pyrestoolbox-mcp && make uv-server

Tools fail with errors

Verify all inputs use Field Units (psia, °F, ft, mD)
Check parameter names match exactly (case-sensitive)
Run validation: uv run python test_tools.py

Runtime Issues

Import errors

# Reinstall dependencies
make uv-install
# or
uv sync --force

Calculation errors

Check units (must be psia, °F, etc.)
Verify inputs are realistic (e.g., API 10-50, temperatures 60-300°F)
Some correlations have valid ranges - try different methods
Check pyResToolbox docs for correlation limits

Performance issues

Array calculations are optimized via numpy
For large datasets, consider batching requests
Docker deployment adds minimal overhead
