+#### 🤖 Claude Code
+
+To add the Azure DevOps MCP Server to Claude Code, use the following command:
+
+```bash
+claude mcp add mcp-ado 'npx -y @azure-devops/mcp ado_org_name' --scope user
+```
+
+For example:
+```bash
+claude mcp add mcp-ado 'npx -y @azure-devops/mcp msazure' --scope user
+```
+
+Replace `msazure` with your Azure DevOps organization name. You can also use `--scope project` to limit the server to a specific project.
+
+For development with a local installation:
+```bash
+claude mcp add mcp-ado 'npx -y ~/git/azure-devops-mcp msazure' --scope user
+```
+
 See the [getting started documentation](./docs/GETTINGSTARTED.md) to use our MCP Server with other tools such as Visual Studio 2022, Claude Code, and Cursor.
