In `@e2e/tests/mcp-external-wizard.spec.ts`:
- Line 142: Move createRoute(routeName) and all subsequent wizard setup and test
actions into the existing try block so any failure triggers the current cleanup
path, while preserving the test’s existing sequencing and assertions.
- Line 104: Apply the repository’s Prettier formatting to the specified changed
blocks: format the chained wizard locator and test sections in
e2e/tests/mcp-external-wizard.spec.ts at lines 104-104, 118-132, and 234-245,
and the test section in e2e/tests/mcp-overview.spec.ts at lines 187-199.
Preserve all test behavior and declarations.
In `@src/components/httproute/HTTPRouteCreatePage.tsx`:
- Line 115: Update parseMatchesFromYAML and inferRuleType so they preserve
whether the YAML match included a path, rather than inferring absence from
default pathType or pathValue values. Classify method-only matches using the
preserved path-presence state, ensuring they render as method matches and retain
the existing path-match behavior when a path was provided.
- Line 399: Update the HTTPRoute form validation in HTTPRouteCreatePage so an
empty rules collection is rejected before submission. Ensure the rules.length
=== 0 condition produces a validation error and prevents sending rules: [],
while preserving validation for valid non-empty rule sets.
In `@src/components/mcp/DestinationRuleFormFields.tsx`:
- Line 21: Remove MUTUAL from TLS_MODE_OPTIONS so the wizard cannot select an
unsupported mutual-TLS mode until credential fields and validation are
implemented; leave the other TLS options unchanged.
In `@src/components/mcp/mcpResourceUtils.ts`:
- Around line 210-211: Update isServiceEntryValid to validate parsed
ServiceEntry values rather than only trimmed input: require at least one
non-empty host after splitting/parsing hosts, and require port to be an integer
in the range 1–65535. Keep buildServiceEntry aligned with the same parsed values
so accepted input cannot produce an empty hosts array or invalid port.
In `@src/components/mcp/ServiceEntryFormFields.tsx`:
- Around line 166-167: Use PageSection as the returned top-level component
around each form in ServiceEntryFormFields.tsx (lines 166-167),
DestinationRuleFormFields.tsx (lines 137-138), and CredentialFormFields.tsx
(lines 137-138), preserving each form’s existing contents.
In `@src/components/mcp/steps/RegisterServerStep.tsx`:
- Line 57: Update the targetHTTPRouteName assignment in the registration
configuration so routeName takes priority whenever it exists, falling back to
targetRef.name only when the wizard has no route. Preserve the existing
empty-string fallback when neither value is available.
In `@src/components/mcp/steps/ServiceEntryStep.tsx`:
- Line 61: Replace the top-level fragment with PageSection in ServiceEntryStep,
DestinationRuleStep, CredentialStep, and RegisterServerStep. Apply the same

The controller rejects credential Secrets without mcp.kuadrant.io/secret: "true" (mcpserverregistration_controller.go:530), so registrations from this wizard go Ready=False and nothing rolls back. Could we add the label here? The e2e also accepts Error creating resources as a pass at spec:183 and never asserts Ready, which is why this slipped through; should we assert Ready there?

This is unconditional, but the internal wizard's existing-route path only sets namespace through this field and validation still requires it, so Save and continue never enables there. Maybe !credentialNamespace?

Gate covers SE/DR/Secret/Registration but not HTTPRoute create (new-route mode) or delete (rollback). Rollback failures are only console.error'd in MCPVerifyStep:174, which can leave the credential Secret behind with no UI signal. Worth adding both?

MCPVerifyStep treats 409 as Already exists success. For a credential Secret that silently drops the token just typed and binds the registration to whatever Secret already had that name. Should we fail or confirm on 409 for this one?

PF only mounts the active step, so changing the credential namespace on step 4 and jumping to step 6 via the nav leaves the registration in the old namespace, where the controller can't find the Secret. Deriving the namespace at build time (wizard:179) would avoid it.

DR host and namespace are retyped with no prefill or check against the ServiceEntry; a mismatch means the DR is ignored and no TLS origination. DISABLE is also offered while the token is mandatory. Could we prefill from parseServiceEntryHosts(...)[0] and the SE namespace?

Revalidate after YAML updates.
Line 79 updates registration state, but this handler does not call onValidationChange. If a user clears metadata.name in valid YAML after the form becomes valid, isServerValid remains true and the wizard attempts invalid resource creation.
Create nextState, then call isMCPServerRegistrationValid(nextState) after onChange.
Proposed fix
- onChange({
+ const nextState = {
registrationName: metadata?.name || '',
namespace: credentialNamespace || metadata?.namespace || '',
targetHTTPRouteName: routeName || targetRef?.name || '',
toolPrefix: typeof spec?.prefix === 'string' ? spec.prefix : '',
- });
+ };
+ onChange(nextState);
+ onValidationChange?.(isMCPServerRegistrationValid(nextState));📝 Committable suggestion

Validate YAML field types before updating form state.
Syntactically valid YAML can assign arrays or objects to fields that the three steps treat as strings. For example, metadata.name: [invalid] is passed to onChange; the validator then calls .trim() and throws. The catch block leaves malformed state stored and the previous validation result unchanged.
Add runtime string checks before onChange in ServiceEntryStep.tsx, DestinationRuleStep.tsx, and CredentialStep.tsx. Reject malformed state and report validation as false. Add tests for incorrect YAML field types.

Most of the last round is sorted: Secret label, allowAlreadyExists: false, the existing-route filter on networking.istio.io/Hostname, DR prefill from the ServiceEntry, YAML revalidation in all four steps, and the internal wizard's button labels are back. Thanks.
Three left. Two of them break things that work on main:
showNamespaceField={false}is now unconditional, which kills the internal wizard's default existing-route path and 4 tests inmcp-wizard.spec.ts.handleAddRuleseeding a match removes theAdd matchbutton, and 3 tests inhttproute-crud.spec.tsstill click it.- The external wizard still builds the registration from
formState.server.namespace.

This is now unconditional, and MCPRegistrationWizard passes no credentialNamespace. It only sets formState.server.namespace inside the routeMode === 'new' branch (MCPRegistrationWizard.tsx:275-279), so in the default existing mode the namespace stays '' from initialServerFormState (types.ts:150), validateRegistrationNamespace fails, and step 2's Next never enables. There's no field left to fix it.
Also removes #server-namespace, which fillStep2 (mcp-wizard.spec.ts:101) and step 2 namespace can be selected (:189) both need. 2 @smoke + 2 @nightly.

Right fix here, but Add match only renders when matches.length === 0 (HTTPRouteRuleWizard.tsx:299-311); once seeded it's a Tabs onAdd with no matching accessible name. :353, :424 and :598 still click it and will time out. 3 @nightly. Same treatment as here, the seeded match is already at index 0.

formState.server.namespace is only kept in sync by RegisterServerStep's effect, and PF mounts just the active step. Visit step 5, go back to step 4, change the credential namespace, then click step 6 in the nav: step 5 never remounts, so the registration lands in the old namespace while the Secret lands in the new one. Controller can't resolve the Secret, Ready=False, rollback fires.
Reading the credential namespace directly avoids the resync entirely.

Same here, otherwise the watch points at the stale namespace.
