⚠️ Limitations
Limited published detail in the provided excerpt (e.g., no explicit tool list, capabilities, or configuration described)
Besides the general configuration outlined above, some MCP clients offer shortcuts for installing MCP servers. Below are instructions for some popular clients, but you can also refer to your specific client's documentation for more details.
The following rules guide large language models (LLMs) in using the UI5 MCP server correctly. Add these rules to your existing global or project-specific AGENTS.md file. The exact location may vary depending on the MCP client. For example, Claude Code uses a CLAUDE.md file instead of AGENTS.md.

Configuration
The UI5 MCP server can be configured using the following environment variables. It does not accept any command-line arguments.
Configuration Options:
UI5_MCP_SERVER_ALLOWED_DOMAINS:
Default Value: localhost, services.odata.org
Description: A comma-separated list of domains that are allowed to be used in various tools, 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.
Default Value: https://sdk.openui5.org for OpenUI5 and https://ui5.sap.com for SAPUI5
Description: Override the base URL used for fetching UI5 resources from the CDN. For example: https://example.com. When set, this URL is used for both OpenUI5 and SAPUI5 resources. The value must be a valid URL. Note that the project's version will appended to the URL automatically. This means that at runtime, the URL might look like this: https://example.com/1.120.0/resources/[...].
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.
