**aas-mcp** is a [Model Context Protocol (MCP)](https://modelcontextprotocol.io/) server that provides AI assistants with tools to interact with [Asset Administration Shells (AAS)](https://industrialdigitaltwin.org/en/content-hub/aasspecifications) via the [Eclipse BaSyx](https://www.eclipse.org/basyx/) REST API.
This MCP server enables AI assistants to perform full CRUD operations on AAS Shells, Submodels, and Submodel Elements, making it ideal for industrial automation, digital twin management, and AAS-based workflows.

## đ§ Configuration
### MCP Client Configuration
To use this server with MCP clients like [Claude Desktop](https://claude.ai/download), add it to your client's configuration:
```json
{
"mcpServers": {
"aas-mcp": {
"command": "aas-mcp",
"env": {
"SHELLSMITH_BASYX_ENV_HOST": "http://localhost:8081"
}
}
}
}
```
> âšī¸ 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:
```bash
export SHELLSMITH_BASYX_ENV_HOST=https://your-host:1234
```
- Create a `.env` file in your working directory with:
```dotenv
SHELLSMITH_BASYX_ENV_HOST=https://your-host:1234
```
Each tool also accepts a `host` parameter to override the default configuration dynamically.
