Merge Risk: 🔵 Low · up to The new violations tool and the shared cluster resolver work as described. Cluster lookup failures may show raw backend error text rather than the consistent user-facing message.

Convert cluster API failures with client.NewError.
The exported resolver returns the raw GetClusters gRPC error through every consuming MCP handler, potentially exposing backend details and bypassing consistent error mapping.
Proposed fix
import ( + "github.com/stackrox/stackrox-mcp/internal/client" ) // ... if err != nil { - return "", fmt.Errorf("failed to fetch clusters: %w", err) + return "", client.NewError(err, "GetClusters") }
As per path instructions, Go MCP server code requires “Proper error wrapping with client.NewError for user-facing errors.”

Idea not relevant to this PR: Maybe we can create a struct ReadOnlyTool that would implement this function and all read only tools can inherit from it. This will make navigation more obvious and easy to list all read only tools.

Sorry, it's been a while since I looked at this.
I didn't want to rely on the time-stamp for alerts being consistently returned from the API, so explicitly format it here.

🟡 Minor · Wrap the GetClusters error with client.NewError. · resolver.go:34
internal/cluster/resolver.go:34
🔒 Security & Privacy | 🟡 Minor | ⚡ Quick winWrap the
GetClusterserror withclient.NewError.
ResolveClusterIDnow serves every toolset handler. Line 34 returns the raw gRPC error throughfmt.Errorf. This bypasses the consistent user-facing error mapping that the other handlers use, for exampleclient.NewError(err, "GetClusters")inclusters.go.The
internal/clientpackage must not importinternal/cluster, so there is no import cycle. The local variableclienton line 25 shadows the package name. Rename it when you add the import.Proposed fix
- client := v1.NewClustersServiceClient(conn) + clustersClient := v1.NewClustersServiceClient(conn) ... - resp, err := client.GetClusters(ctx, &v1.GetClustersRequest{ + resp, err := clustersClient.GetClusters(ctx, &v1.GetClustersRequest{ Query: query, }) if err != nil { - return "", fmt.Errorf("failed to fetch clusters: %w", err) + return "", client.NewError(err, "GetClusters") }Note: the test at
resolver_test.goexpects the text "failed to fetch clusters:". Update the test expectation, becauseclient.NewErrorproduces a different message.As per path instructions, Go code needs "Proper error wrapping with client.NewError for user-facing errors".
