Setup

Standard setup for most clients

This configuration works in most tools:

{
	"mcpServers": {
		"@ui5/mcp-server": {
			"type": "stdio",
			"command": "npx",
			"args": [
				"@ui5/mcp-server"
			]
		}
	}
}

Configuration

The UI5 MCP server can be configured using the following environment variables. It does not accept any command-line arguments.

• UI5_MCP_SERVER_ALLOWED_ODATA_DOMAINS:
  • Default Value: localhost, services.odata.org
  • Description: A comma-separated list of domains that are allowed to be used in the oDataV4Url parameter of the create_ui5_app tool, for example: localhost, example.com, sub.example.com. Set to an empty string to allow any domains.
    For wildcard subdomains, prefix the domain with a dot: .example.com. This will match www.example.com but not example.com.
• UI5_MCP_SERVER_RESPONSE_NO_STRUCTURED_CONTENT:
  • Description: Set to any value to disable structured content in the MCP server responses.
• UI5_MCP_SERVER_RESPONSE_NO_RESOURCES:
  • Description: Set to any value to disable resources in the MCP server responses. This is useful for clients that do not support resources, such as Cursor or the Gemini CLI.
• UI5_LOG_LVL:
  • Default Value: info
  • Description: Internal log level: silent, error, warn, info, perf, verbose, silly
• UI5_DATA_DIR:
  • Default Value: The .ui5 directory in the user's home directory
  • Description: Directory where the MCP server stores its data, such as cached API references

Example Configuration:

{
	"mcpServers": {
		"@ui5/mcp-server": {
			"type": "stdio",
			"command": "npx",
			"args": [
				"@ui5/mcp-server"
			],
			"env": {
				"UI5_MCP_SERVER_ALLOWED_ODATA_DOMAINS": "localhost, services.odata.org",
				"UI5_LOG_LVL": "verbose",
				"UI5_DATA_DIR": "/path/to/custom/data/dir"
			}
		}
	}
}
