+### MCP
+
+Control which API endpoints are exposed as tools in your [MCP server](/ai/model-context-protocol) using `x-mint: mcp`. By default, all endpoints are available as MCP tools. Use this extension to exclude endpoints or customize how they appear to AI applications.
+
+```json {8-12}
+{
+  "paths": {
+    "/users": {
+      "get": {
+        "summary": "Get users",
+        "description": "Retrieve a list of users",
+        "x-mint": {
+          "mcp": {
+            "enabled": false
+          }
+        }
+      }
+    }
+  }
+}
+```
+
+The `x-mint: mcp` extension supports these properties:
+
+| Property | Type | Description |
+| :------- | :--- | :---------- |
+| `enabled` | `boolean` | Set to `false` to exclude this endpoint from your MCP server. Defaults to `true`. |
+| `name` | `string` | Override the tool name that appears in AI applications. Defaults to the operation's `summary`. |
+| `description` | `string` | Override the tool description. Defaults to the operation's `description`. |
+
+This example excludes an internal endpoint and customizes another:
+
+```json {8-10, 21-25}
+{
+  "paths": {
+    "/internal/metrics": {
+      "get": {
+        "summary": "Get internal metrics",
+        "description": "Returns system metrics for monitoring",
+        "x-mint": {
+          "mcp": {
+            "enabled": false
+          }
+        }
+      }
+    },
+    "/users/search": {
+      "post": {
+        "summary": "Search users",
+        "description": "Search for users by various criteria",
+        "x-mint": {
+          "mcp": {
+            "name": "search_users",
+            "description": "Find users by name, email, or other attributes. Returns matching user profiles."
+          }
+        }
+      }
+    }
+  }
+}
+```
+
+<Note>
+  The legacy `x-mcp` extension is still supported but deprecated. Use `x-mint: mcp` for new configurations.
+</Note>
+
 ### Href
 
 Set the URL of the autogenerated endpoint page using `x-mint: href`. When `x-mint: href` is present, the generated API page uses the specified URL instead of the default autogenerated URL.
