fix(mcp): explain managed server add progress (Refs #12672) - #14249
Managed MCP add now labels its two policy phases and reports credential synchronization and agent registration. The command explains that synchronization is required even with --no-probe, so the wait no longer appears to be an unexplained duplicate policy application.
Reason
The macOS reproduction in #12672 completed successfully after about 70 seconds, beyond its automation timeout. OpenShell requires the route policy before provider attachment and the credential binding afterward. Removing either phase or its readiness checks would change credential safety.
Related issues
Refs #12672. This addresses the progress messages. The external QA harness timeout and first-add latency on macOS still need validation, so this PR does not close the issue.
Prior work: #9721 added post-binding credential republishing; #10307 required stable credential revisions before adapter registration. This change preserves those safeguards.
Changes
Add progress messages in the existing MCP add lifecycle before opening the route, binding the credential, waiting for synchronization, and registering the server. An orchestration regression checks that each message is visible before the corresponding operation and excludes the host credential value.
Verification
The new regression failed before the production change because all five observed operation boundaries had no progress message.
npx --no-install vitest run --project cli src/lib/actions/sandbox/mcp-bridge-hermes-add-finality.test.ts src/lib/actions/sandbox/mcp-bridge-provider.test.ts src/lib/actions/sandbox/mcp-bridge-status-resolution.test.ts src/lib/actions/sandbox/mcp-bridge-restart-recovery.test.ts --coverage=false: 106 tests passed, including the subprocess --no-probe dispatch cases.
Normal pre-commit, commit-msg, and pre-push hooks passed, including publication validation and CLI typechecking.
Live macOS first-add validation was not run. The contributor doctor rejected Docker's 7.7 GiB memory allocation. The lifecycle test uses the shared add path through a Hermes fixture; external services are mocked.
The two-file diff contains no secrets, API keys, or credentials. No live E2E assertion or timeout changes.
Review notes
Decision: Accept the progress-message change. Reason: the reported duplicate application is a required two-phase policy sequence. Placement: the existing MCP add orchestrator. Accountable maintainer: @deepujain. Validation plan: the failing-then-passing progress regression, provider and recovery tests, --no-probe dispatch coverage, publication hooks, and independent CI and review.
Independent pre-publication review of latest PR commit 812fe11f0039ac073151ec6aa9273779c35ef42d found no blocking correctness, security, scope, or writing issues. Hosted CI and automated reviews remain pending. DGX Station hardware evidence is not applicable.
Adding an MCP server now displays progress updates as setup advances, including policy configuration, credential synchronization, and server registration. Credential synchronization progress is shown even when probing is skipped.
Bug Fixes
Improved admission checks to reliably read command output and confirm that no native sandbox commands run during the check.
The MCP add flow now logs progress during policy setup, credential synchronization, and agent registration. Tests verify the message order, check that logs omit the host credential, and validate trusted-private admission output.

Summary
Add-phase progress messages and validation src/lib/actions/sandbox/mcp-bridge-add-restart.ts, src/lib/actions/sandbox/mcp-bridge-hermes-add-finality.test.ts
The add flow logs progress before policy setup, credential binding, credential synchronization, and agent registration. The Hermes test checks the expected message order and verifies that logs omit the host credential.
The messages clarify add progress but do not shorten synchronization. No merge-blocking risk is established.

Unverified finding
Verification ran but could not confirm this finding. It is shown for review, not as a verified issue.
Assert a new message before the second credential wait.
When a fresh add republishes the host credential, the action waits for synchronization a second time. It logs the synchronization message only before the first wait. This line records that same last message twice, so the test passes without detecting the missing progress message. Add a message before the second wait. Then assert two distinct console.log calls.

Approved commit 5a9382d against base 64c6ffe. The change reports the managed MCP add phases without changing their credential or network-policy sequence. Source tests check phase order, credential-free output, and the subprocess result consumer. The trusted PR gate found all 72 current checks passing, all five commits Verified, and no unresolved CodeRabbit finding. The PR Review Advisor passed and recommended no additional live E2E for this progress-output change. This review does not claim to resolve the separate first-add latency in #12672. I found no blocking correctness, security, or product-scope issue.
