Overview | DAFoam

Edit me

The DAFoam AI Assistant enables the conversational pre-processing, simulations, optimization, and post-processing of various DAFoam cases. Currently, we support only airfoil cases with the Claude LLM. The DAFoam MCP server is in the beta state.

Installation

Install the MCP server

Download and install the Docker Desktop for MacOS or Windows. Open Docker Desktop and keep it open.
Open a Terminal (MacOS) or Command Prompt (Windows). Run the following command to download the DAFoam Docker image:
```
docker pull dafoam/opt-packages:latest
```
Run the following command to download the dafoam_mcp_server repo from GitHub
```
git clone https://github.com/dafoam/dafoam_mcp_server.git
```
Alternative: If you don’t have git, you can also download the repo from here and unzip it. Then, rename the unzipped folder to dafoam_mcp_server.
Open a Terminal (MacOS) or Command Prompt (Windows) and cd into the dafoam_mcp_server directory, then run the following to build the dafoam_mcp_server docker image
```
docker build -t dafoam_mcp_server . 
```

Connect the DAFoam MCP server to a client (Claude).

Download and install the Claude Desktop from https://www.claude.com/download. Open Claude Desktop (you may need to sign up for an account).
In Claude Desktop, locate to the bottom left and click: “Your Account->Settings->Developer”. Then, click “Edit Config”, this will open a directory where Claude saves your claude_desktop_config.json file.
Open claude_desktop_config.json and add the following lines into it. NOTE: you need to replace abs_path_to_your_dafoam_mcp_server with the absolute path of the dafoam_mcp_server folder on your local system. For example, you may use /Users/phe/Desktop/dafoam_mcp_server:/home/dafoamuser/mount for MacOS and C:\\Users\\phe\\Desktop\\dafoam_mcp_server:/home/dafoamuser/mount for Windows (we need to use double slash in the path for Windows!). The DAFoam MCP will make modifications ONLY in this dafoam_mcp_server folder.

        "dafoam_mcp_server"
      ]
    }
  }
}
```
IMPORTANT! You need to close and re-open Claude Desktop to make the new MCP effective.
