PRACTICAL FIELD GUIDE
Verify an agent's backend change after the tool returns
A successful tool response is one part of verification, not proof that the full feature works. Confirm the persisted schema and application behavior under the credentials that will use it.

Put it into practice
- Read the affected table or configuration again after the tool reports success.
- Exercise the generated endpoint with the intended caller type and a disposable record.
- Check a denied case as well as the successful case before closing the change.
What this looks like
ILLUSTRATIVE EXAMPLE
The agent creates a table successfully, but the frontend cannot access it because no end-user policy was configured. The tool did its job; the feature remains incomplete.
A boundary to keep clear
Avoid reporting an end-to-end feature complete solely from a schema mutation response.
MCPBackend context
MCPBackend's remote MCP server manages supported project configuration through your authorized account. Your running app uses the separate data API. A successful connection does not prove every tool call succeeded: inspect tool results, verify the project identity and read the current schema before a change.
Take the next step
Inspect the current project contract, try the change with disposable data, and verify the result through the same credentials your app will use. Record the expected response and one denied-access case before release.
