-
-    ```yaml title="Config file"
-    operations:
-      source: local
-      paths:
-      - ./graphql/TheSpaceDevs/operations
-    ```
-
     ```sh showLineNumbers=false
     rover dev --supergraph-config ./graphql/TheSpaceDevs/supergraph.yaml \
-    --mcp <path to the preceding config>
+    --mcp ./graphql/TheSpaceDevs/config.yaml
