 You can use the Apify MCP Server in two ways:
 
-- Standard Input/Output (stdio) which is useful for local integrations and command-line tools (e.g. Claude desktop)
-- Use [mcp.apify.com](https://mcp.apify.com) by connecting your MCP client with `Authorization: Bearer <APIFY_TOKEN>` header
+- Standard Input/Output (stdio): Ideal for local integrations and command-line tools such as the Claude desktop client.
+    - Set MCP client server command to `npx @apify/actors-mcp-server` and environment variable `APIFY_TOKEN` to your Apify API token
+    - See `npx @apify/actors-mcp-server --help` for more options
+- HTTPS Endpoint [mcp.apify.com](https://mcp.apify.com): Connect your MCP client by including `Authorization: Bearer <APIFY_TOKEN>` header in your requests.
+    - `https://mcp.apify.com` for streamable transport
+    - `https://mcp.apify.com/sse` for legacy SSE transport
 
 _(You could also use legacy option by running [Apify Actors MCP Server](https://apify.com/apify/actors-mcp-server) as Actor.)_
