 - Check that your GraphQL endpoint accepts the provided headers
 - When using `rover dev` you can test your GraphQL endpoint using Sandbox at [http://localhost:4000](http://localhost:4000)
 
-## Step 4: Working with MCP Tools
-Now that your MCP server is connected, learn how to customize and create tools.
-
-### Understanding Tools
-
-MCP tools are GraphQL operations that Claude can execute. Each operation in your `operations/` directory becomes a tool with:
-
-- **Tool name**: Derived from the operation name
-- **Description**: From GraphQL comments or operation descriptions
-- **Parameters**: Mapped from GraphQL variables
-- **Response**: The GraphQL response data
-
-### Defining Custom Tools
-
-Create new tools by adding GraphQL operation files to your `operations/` directory:
-
-```graphql
-# operations/GetProducts.graphql
-
-# Retrieves product information by ID
-query GetProducts($productId: ID!) {
-  product(id: $productId) {
-    id
-    name
-    price
-    description
-  }
-}
-```
-
-Apollo MCP Server automatically detects new `.graphql` files and exposes them as tools. No server restart needed!

-
-### Testing Operations in GraphOS Studio
-
-The `rover dev` command command includes Sandbox:
-
-1. Open http://localhost:4000 in your browser
-2. Test your operations directly:
-   - Browse your schema
-   - Run queries and mutations
-   - Experiment with variables
-   - View responses
-
-This is invaluable for:
-- Verifying operations before exposing them as MCP tools
-- Understanding your schema structure
-- Debugging query issues
-- Exploring available data
