Concrete-Properties-MCP Server

A Model Context Protocol Server for Reinforced Concrete Section Analysis

🚀 Overview

The Concrete-Properties-MCP Server provides a unified API interface for interacting with the **Concrete Properties** Python library. It enables AI-driven calculation of section properties and capacities of reinforced concrete sections through a consistent interface.

✨ Supported Features

• Section Properties:
• Calculate geometric properties (area, centroid, moment of inertia, etc.)
• Compute transformed section properties
• Reinforced Concrete Analysis:
• Calculate axial, bending, and combined capacities
• Determine interaction diagrams
• Material Properties:
• Define concrete and reinforcement material properties
• Support for multiple concrete grades and steel types

🖥️ MCP Tools

The server provides the following main API functions:

• rectangular_concrete_area_properties: Compute the rectangular concrete section geometric properties.
• arbitrary_concrete_area_properties: Compute arbitrary concrete section geometric properties.
• rectangular_concrete_bending_capacity: Compute the rectangular concrete section bending capacities (Mx+, Mx- and My) under the given axial load.
• rect_concrete_axial_moment_x_points: Compute the rectangular concrete section axial - moment/bending (around X) interaction diagram points.
• rect_concrete_axial_moment_y_points: Compute the rectangular concrete section axial - moment/bending (around Y) interaction diagram points.
• rect_concrete_axial_moment_x_image: Plots the rectangular concrete section axial - moment/bending (around X) interaction diagram points.
• rect_concrete_axial_moment_y_image: Plots the rectangular concrete section axial - moment/bending (around Y) interaction diagram points.

⚙️ Installation

Requirements

Required Python libraries:

mcp>=0.1.0                 # Model Control Protocol library
matplotlib>=3.10.1         # Library for plots
concreteproperties>=0.6.4  # Concrete Properties library

Guide

1. Install the required Python libraries from the command line:

pip install mcp concreteproperties matplotlib
   //or
   pip install -r requirements. txt

2. Download this repository and save the extracted files locally (e.g., at ``C:\your_path_to_the_extracted_server\concrete-properties-mcp\``).

3. (Optional) Edit the MCP server configuration file, located at src/config.json (see configuration section).

4. Install Claude Desktop (or another AI client with MCP support).

5. Configure Claude Desktop to launch the MCP Server automatically (see Claude Desktop section).

6. You are good to go!

Open 5ire > Tools > New, input the following info and then click Save:

Caution: Update the path! (single slashes)

Then turn on the server and you are good to go!

Claude Desktop

Open Claude Desktop and navigate to File > Settings > Developer > Edit Config, edit claude_desktop_config.json and add the following JSON.

{
    "mcpServers": {
        "concrete": {
            "command": "python",
            "args": [
                "C:\\your_path_to_the_extracted_server\\concrete-properties-mcp\\src\\server.py"
            ]
        }
    }
}

Caution: Update the path and use double backslashes!

Then restart Claude Desktop (from the tray icon, right click > Quit).

Visual Studio Code - GitHub Copilot

The MCP server is already setup in .vscode\mcp.json. Open the repository folder in visual studio, select .vscode\mcp.json and click "Start" above the server name (more info here).

🐛 Debug

You can test and debug the MCP server using the MCP Inspector by running the following command:

npx @modelcontextprotocol/inspector mcp run src\server.py
