🔧 Configuration

MCP Client Configuration

To use this server with MCP clients like Claude Desktop, add it to your client's configuration:

{
  "mcpServers": {
    "aas-mcp": {
      "command": "aas-mcp",
      "env": {
        "SHELLSMITH_BASYX_ENV_HOST": "http://localhost:8081"
      }
    }
  }
}

ℹ️ Change the value of SHELLSMITH_BASYX_ENV_HOST to match your BaSyx Environment host URL

The configuration format is similar for other MCP clients like LM Studio.

BaSyx Environment Configuration

The MCP server connects to an Eclipse BaSyx environment. The default host is:

http://localhost:8081

You can override it in several ways:

• Set the environment variable:

  export SHELLSMITH_BASYX_ENV_HOST=https://your-host:1234

• Create a .env file in your working directory with:

  SHELLSMITH_BASYX_ENV_HOST=https://your-host:1234

Each tool also accepts a host parameter to override the default configuration dynamically.
