Use SecretBridge to inspect the Ubuntu test environment: system, CPU, memory and disk. Read only; do not change the system.
I will use SecretBridge’s controlled SSH tool and review the resource and operation scope first.
Plugin installation commands
secretbridge client-plugin codex <new-absolute-directory>
codex plugin marketplace add <same-absolute-directory>
codex plugin add secretbridge@secretbridge-localInstall and initialize SecretBridge first, then replace the placeholders. Current Codex CLI versions have a marketplace-manifest compatibility issue; verify callable MCP tools after installation.
secretbridge_begin_conversationCompleteRegister a separate conversation and use the console’s language for operation descriptions.
secretbridge_list_catalogCompleteFound “Ubuntu test environment”. The tool returns metadata and opaque references, not passwords.
secretbridge_request_sshRequestedInspect the command
/usr/bin/bash -lc
printf 'SYSTEM\n'; uname -sr; printf '\nCPU\n'; getconf _NPROCESSORS_ONLN; printf '\nMEMORY\n'; free -m; printf '\nDISK\n'; df -h /20-second timeout · SSH fingerprint verified by the user through a trusted channel · Individually quoted arguments
The user reviews the command in SecretBridge and approves this item. Per-operation approval remains enabled; the plugin does not generate authorization.
After local approval → Approvedsecretbridge_get_approvalapprovedsecretbridge_create_runExecutedUse the approved request and one stable idempotency key. Credentials are used only inside the broker for SSH authentication.

Illustrative interface with edited conversation text; tool names and flow follow the real test. Results come from an approved SSH check on 2026-09-29. Codex is an OpenAI product; this demo does not imply endorsement or marketplace listing. Plugin integration guide
Explore the interface, then inspect real-device captures.
High-resolution interface previews show resources, approval, execution and history with isolated test data.
Interface previews use the current SecretBridge frontend and isolated test data; they do not represent a real connection or execution.
