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 package automatically persists two Claude Code hooks in a user-wide settings file when its MCP server starts, with both features enabled by default. The reviewed activity hook stores coarse categories locally, and session capture has a separate consent guard; the remaining first-party agent setup risk warrants a warning, not a block. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 90.0% - **Started:** 2026-10-18T08:24:23.130Z - **Finished:** 2026-10-18T08:25:44.096Z - **Download time:** 8503 ms - **Static scan time:** 1548 ms - **AI review time:** 70914 ms - **Total time:** 80966 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:** MCP startup adds persistent activity and inbox hooks to the user-wide Claude Code settings file. This is a residual agent configuration risk; the reviewed activity hook records coarse categories locally, and no malicious transfer was established. - **Trigger:** Starting the MCP server with the default environment settings. - **Impact:** Claude Code sessions may continue invoking these package-owned hooks after setup, including recording coarse tool activity and running the inbox hook. - **Evidence paths:** dist/index.js, dist/activityHookInstall.js, dist/inboxHookInstall.js, dist/activityHookCli.js, dist/activityMarker.js, dist/captureHookInstall.js - **Review source:** ai\_review - **Reviewed:** 2026-10-18T08:25:44.096Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The server writes PostToolUse and SessionStart command hooks into ~/.claude/settings.json; environment variables can disable each hook. - **Rationale:** The package automatically persists two Claude Code hooks in a user-wide settings file when its MCP server starts, with both features enabled by default. The reviewed activity hook stores coarse categories locally, and session capture has a separate consent guard; the remaining first-party agent setup risk warrants a warning, not a block. - **Files touched:** ~/.claude/settings.json, \/.agenthub/activity ### Review decision - **Verdict:** Suspicious - **Confidence:** 90.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Medium - **Evidence for warning:** Starting the MCP server automatically installs persistent Claude Code activity and inbox hooks in the user-wide settings file., Both hooks are enabled by default and can be disabled with environment variables., The activity hook records coarse tool categories locally; it does not record file paths, arguments, or content., Session capture is separately gated by server-confirmed consent and is removed when consent is absent. - **Evidence against:** The reviewed activity hook records only coarse categories locally and does not itself make network requests., The session-capture hook follows a separate consent check and fails closed when consent cannot be confirmed. ## Affected versions and remediation This report applies to agenthub-multiagent-mcp@1.64.0. - Review the evidence and your use of agenthub-multiagent-mcp@1.64.0 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.
