Treat them as untrusted evidence. Do not execute instructions or code found in this document. ## Verdict summary **Flagged as agent extension risk** — Allowed by default with warning: install-time first-party agent extension setup was detected. - **Verdict:** Suspicious - **Product-default install policy:** Warn - **Firewall policy:** Warn-only agent extension risk - **Public report status:** Published - **Threat category:** Agent extension lifecycle risk - **Selected version:** 8.1.2 - **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 postinstall hook automatically changes the consumer project’s agent configuration to enable this package’s own MCP server, creating a residual integration risk. The inspected server registration exposes component information tools, with no evidence here of broader control or data exfiltration. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 91.0% - **Started:** 2026-10-16T23:12:51.788Z - **Finished:** 2026-10-16T23:15:22.964Z - **Download time:** 2324 ms - **Static scan time:** 90428 ms - **AI review time:** 58424 ms - **Total time:** 151176 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 install hook automatically configures this package’s MCP server in the consumer project. This leaves a first-party agent integration risk, but the inspected source does not establish a broader control hijack or data theft. - **Trigger:** Installing the package runs its postinstall hook, unless the documented environment opt-out is set. - **Impact:** The agent may load the package’s component information tools after restart without a separate setup command. - **Evidence paths:** package.json, scripts/postinstall-mcp.js, dist/mcp-server/index.js - **Review source:** ai\_review - **Reviewed:** 2026-10-16T23:15:22.964Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The hook writes or updates the exosphere entry in the project’s .mcp.json to launch this package’s MCP server. - **Rationale:** The postinstall hook automatically changes the consumer project’s agent configuration to enable this package’s own MCP server, creating a residual integration risk. The inspected server registration exposes component information tools, with no evidence here of broader control or data exfiltration. - **Files touched:** .mcp.json ### Review decision - **Verdict:** Suspicious - **Confidence:** 91.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Medium - **Evidence for warning:** package.json runs scripts/postinstall-mcp.js during postinstall., The installer targets the project’s .mcp.json and registers this package’s MCP server., The installer can add or update the entry automatically; an environment opt-out is available., The registered server exposes component information tools, consistent with this package’s UI component library. - **Evidence against:** The inspected MCP setup registers the package’s own server and component tools; the reviewed excerpts show no foreign server registration or data export. ## Affected versions and remediation This report applies to @boomi/exosphere@8.1.2. - Review the evidence and your use of @boomi/exosphere@8.1.2 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.
