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. Postinstall performs first-party agent skill setup in package-owned .agents namespaces and, by default, can forward an existing access token to any operator-configured MCP URL. That is install-time agent-surface mutation and conditional credential exposure, not a proven hidden exfiltration or foreign control-surface hijack. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 81.0% - **Started:** 2026-09-22T16:51:13.961Z - **Finished:** 2026-09-22T16:53:10.853Z - **Download time:** 757 ms - **Static scan time:** 801 ms - **AI review time:** 115333 ms - **Total time:** 116892 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:** npm postinstall copies this package's agent skills into the consumer project's .agents/skills/command-center directory. Unless an opt-out env var is set, it can also download platform skill text and write it under .agents/skills/mainsequence when an MCP URL and access token are already configured. - **Trigger:** Automatic npm postinstall in a non-global consumer project, with MCP writes only when URL and token environment variables are present and COMMAND\_CENTER\_SDK\_MCP\_POSTINSTALL is not 0. - **Impact:** Agent skill files in the consumer project change without a separate user command. A configured access token is sent to an endpoint that is not limited to one host. No hidden recipient, secret scraping, or code execution chain was found. - **Evidence paths:** package.json, cli/postinstall.mjs, cli/install-agent-skills.mjs, cli/install-mcp-skills.mjs, cli/mcp-platform-skills.mjs - **Review source:** ai\_review - **Reviewed:** 2026-09-22T16:53:10.853Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** installAgentSkills copies packaged skill trees into the command-center namespace and prunes other entries there. The MCP path posts the bearer token to the operator-configured HTTP(S) endpoint and writes the returned skill files into the mainsequence namespace. - **Rationale:** Postinstall performs first-party agent skill setup in package-owned .agents namespaces and, by default, can forward an existing access token to any operator-configured MCP URL. That is install-time agent-surface mutation and conditional credential exposure, not a proven hidden exfiltration or foreign control-surface hijack. - **Files touched:** .agents/skills/command-center, .agents/skills/mainsequence ### Review decision - **Verdict:** Suspicious - **Confidence:** 81.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Medium - **Evidence for warning:** package.json postinstall runs node ./cli/postinstall.mjs on install., postinstall calls installAgentSkills with command npm postinstall for the consumer INIT\_CWD., That installer writes packaged skills under .agents/skills/command-center and removes unauthorized entries in that namespace., Unless COMMAND\_CENTER\_SDK\_MCP\_POSTINSTALL is 0, postinstall also installs remote MCP skills under .agents/skills/mainsequence when URL and token env vars exist., The MCP URL is any http or https value from the environment, and MAINSEQUENCE\_ACCESS\_TOKEN is sent as a bearer token to that URL. - **Evidence against:** Global installs and the SDK source repository are skipped., Writes stay inside the command-center and mainsequence skill namespaces., MCP sync is skipped when URL or token is missing and failures do not stop the npm install., Dependencies do not include this package name, so there is no nested lifecycle self-install chain., Git and npm spawn helpers are on explicit CLI maintenance paths, not the postinstall path. ## Affected versions and remediation This report applies to @dev-mainsequence/command-center-sdk@0.4.3. - Review the evidence and your use of @dev-mainsequence/command-center-sdk@0.4.3 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.
