What You'll Need

Set these up before or after installing:

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'.Optional

Environment variable: UI5_MCP_SERVER_ALLOWED_DOMAINS

Set to any value to disable structured content in the MCP server responses.Optional

Environment variable: UI5_MCP_SERVER_RESPONSE_NO_STRUCTURED_CONTENT

Set to any value to disable resources in the MCP server responses, see https://modelcontextprotocol.io/specification/2025-06-18/server/resource. This is useful for clients that do not support resources, see https://modelcontextprotocol.io/clients, such as Cursor or the Gemini CLI.Optional

Environment variable: UI5_MCP_SERVER_RESPONSE_NO_RESOURCES

Internal log level (https://ui5.github.io/cli/stable/pages/Troubleshooting/#changing-the-log-level): 'silent', 'error', 'warn', 'info', 'perf', 'verbose' or 'silly'Optional

Environment variable: UI5_LOG_LVL

Directory where the MCP server stores its data, such as cached API references. Defaults to the '.ui5' directory in the user's home directory.Optional

Environment variable: UI5_DATA_DIR

  • npm Version v8.0.0 or higher
  • An MCP client, such as VS Code (GitHub Copilot), Cline, Claude Code, Codex, or any other MCP-compatible client

Setup

Standard Configuration for Most Clients

This configuration works for most MCP clients:

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

Specific MCP Clients

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.

VS Code

Preferred: Install from the GitHub MCP server registry

Alternatively you can use the VS Code CLI:

# Using VS Code CLI
code --add-mcp '{"name":"@ui5/mcp-server","type": "stdio","command":"npx","args":["-y", "@ui5/mcp-server"]}'
Cline
  1. Open the Cline panel in VSCode.
  2. Click on the "MCP Servers" icon at the top, next to the "plus" symbol
  3. Change to the "Configure" tab, then click "Configure MCP servers"
  4. In the editor that opens, insert the above Standard Configuration for Most Clients

See docs.cline.bot/mcp/adding-and-configuring-servers for details.

Claude Code
claude mcp add --transport stdio --scope user ui5-mcp-server -- npx -y @ui5/mcp-server
Codex
codex mcp add --transport stdio ui5-mcp-server -- npx -y @ui5/mcp-server

Adding Rules to your Project

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.

## Guidelines for UI5

Use the `get_guidelines` tool of the UI5 MCP server to retrieve the latest coding standards and best practices for UI5 development.

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.
  • UI5_MCP_SERVER_RESPONSE_NO_RESOURCES:

    • 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/[...].
  • UI5_LOG_LVL:
    • Default Value: info
    • Description: Internal log level: silent, error, warn, info, perf, verbose, silly
