+### Implementation metadata
+
+Skybridge passes the first `McpServer` argument through as MCP implementation metadata. Add `icons` there to advertise a Connector icon to Claude and other MCP clients that support implementation icons:
+
+```typescript
+import { McpServer } from "skybridge/server";
+
+const server = new McpServer(
+  {
+    name: "coffee-finder",
+    title: "Coffee Finder",
+    version: "0.0.1",
+    icons: [
+      {
+        src: "https://example.com/icon.png",
+        mimeType: "image/png",
+        sizes: ["128x128"],
+        theme: "light",
+      },
+    ],
+  },
+  { capabilities: {} },
+);
+```
+
+Use an HTTPS URL when testing through a public tunnel, or a `data:` URI for a self-contained icon. Local file paths are not reachable by remote clients. Host support can vary, so keep the icon metadata in your server even if a client does not display it yet.
