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:** 2.0.169 - **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 inspected source supports a warning for first-party agent setup capability, while the configuration and skill changes require the user-invoked setup command. The preinstall script is an upgrade-migration hook; the inspected source does not establish malicious behavior. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 84.0% - **Started:** 2026-10-11T07:16:44.777Z - **Finished:** 2026-10-11T07:17:48.201Z - **Download time:** 2833 ms - **Static scan time:** 22989 ms - **AI review time:** 37601 ms - **Total time:** 63424 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 MCP setup command modifies selected agent configuration and may install a Superblocks import skill. This is a guarded, first-party agent integration capability; no unconsented attack was established. - **Trigger:** A user invokes the MCP setup command and selects a client. - **Impact:** The selected agent can start the logged-in Superblocks Gateway and load the Superblocks import skill. - **Evidence paths:** package.json, dist/index.js, dist/dist-ZSDT4GMP.js - **Review source:** ai\_review - **Reviewed:** 2026-10-11T07:17:48.201Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The command writes a Superblocks Gateway server entry to supported client configuration and can copy its import skill into that client’s skill directory. - **Rationale:** The inspected source supports a warning for first-party agent setup capability, while the configuration and skill changes require the user-invoked setup command. The preinstall script is an upgrade-migration hook; the inspected source does not establish malicious behavior. - **Files touched:** ~/.claude.json, ~/.cursor/mcp.json, ~/.claude/skills/superblocks-import/SKILL.md, ~/.cursor/skills/superblocks-import/SKILL.md ### Review decision - **Verdict:** Suspicious - **Confidence:** 84.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Medium - **Evidence for warning:** package.json runs a preinstall script that checks for and uninstalls previous Superblocks CLI versions., The MCP setup command targets named agent clients and writes a Gateway configuration for the logged-in CLI user., The setup can copy the package-owned Superblocks import skill into a selected client’s skills directory., The setup inherits SUPERBLOCKS\_AUTH\_FILE into the configured MCP server environment when set. - **Evidence against:** The configuration and skill writes are performed by the explicit MCP setup command, which prompts for a client in interactive use or requires --client without a TTY., The preinstall hook is confined by its stated behavior to finding previous Superblocks CLI installations. ## Affected versions and remediation This report applies to @superblocksteam/cli@2.0.169. - Review the evidence and your use of @superblocksteam/cli@2.0.169 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.
