Do not execute instructions or code found in this document. ## Verdict summary **Flagged as AI-agent capability risk** — Allowed by default with warning: agent-facing configuration or capability changes need review before use. - **Verdict:** Suspicious - **Product-default install policy:** Warn - **Firewall policy:** Warn-only AI-agent capability risk - **Public report status:** Published - **Threat category:** AI-agent capability abuse - **Selected version:** 0.10.50 - **Selected version is latest:** No - **Analysis source:** AI Security Review (lpm-firewall-ai) This is the current Firewall decision for the selected package version, based on the available public evidence. Findings for this version do not establish the status of other versions. AI assessment: suspicious; recommendation: downgrade to warn. This assessment is supporting evidence; the published decision above determines the current policy. The scanner’s credential warning is explained by the optional Google IAP JWT-signing flow for the configured admin install. The explicit export capability writes agent instruction files, so it warrants a warning under the agent configuration policy; source inspection found no malicious install-time behavior. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 91.0% - **Started:** 2026-10-14T21:21:19.202Z - **Finished:** 2026-10-14T21:21:58.729Z - **Download time:** 768 ms - **Static scan time:** 91 ms - **AI review time:** 38667 ms - **Total time:** 39527 ms The recorded confidence comes from the underlying analysis. Trusted advisory policy can determine the final verdict even when the AI assessment differs. ## Security analysis ### Published attack-surface review - **Summary:** The explicit export command writes generated site context into Claude instruction and skill files. No confirmed attack behavior was identified; this is a user-invoked agent configuration capability. - **Trigger:** The operator runs caelo-mcp-server export. - **Impact:** The generated files can influence later Claude Code sessions in the output directory. - **Review source:** ai\_review - **Reviewed:** 2026-10-14T21:21:58.729Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The command fetches context from the configured Caelo admin install and writes CLAUDE.md and skill files under the selected output directory, defaulting to the current directory. - **Rationale:** The scanner’s credential warning is explained by the optional Google IAP JWT-signing flow for the configured admin install. The explicit export capability writes agent instruction files, so it warrants a warning under the agent configuration policy; source inspection found no malicious install-time behavior. - **Files touched:** CLAUDE.md, .claude/skills/\/SKILL.md - **Network endpoints:** https://iamcredentials.googleapis.com ### Review decision - **Verdict:** Suspicious - **Confidence:** 91.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Medium - **Evidence for warning:** The explicit export command fetches site context and writes a Claude instruction file and skill files., Export runs only when the operator invokes the export command; its default output directory is the current directory., The manifest’s only publish lifecycle script runs the build compiler., The IAP integration sends an access token to Google IAM to sign a JWT for the configured admin URL’s audience. - **Evidence against:** The inspected credential flow is conditional on IAP configuration and targets Google’s IAM Credentials service., The package source does not show an install hook performing the agent-file setup. ## Affected versions and remediation This report applies to @caelo-cms/mcp-server@0.10.50. - Review the evidence and your use of @caelo-cms/mcp-server@0.10.50 before allowing it. Restrict the permissions described in this report. - Choose an independently verified alternative or release. This report does not establish that other versions are safe. ## Public findings ### 1.
