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 MCP server automatically writes global Claude Code skills and hooks, including a session-start prompt that directs the agent to process inbox messages before the user’s request. This is a meaningful agent-control capability exposed by default, though its stated purpose and side-effect limits do not establish malicious intent. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 88.0% - **Started:** 2026-10-30T06:45:29.809Z - **Finished:** 2026-10-30T06:46:29.673Z - **Download time:** 520 ms - **Static scan time:** 1656 ms - **AI review time:** 57687 ms - **Total time:** 59864 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:** Automatic MCP startup modifies global Claude Code configuration and adds a session-start prompt that causes inbox handling before the user’s request. - **Trigger:** Starting the package’s MCP server; the hooks are enabled by default and can be disabled with their respective environment settings. - **Impact:** This gives the package influence over later Claude Code sessions and can cause the agent to read and answer team messages before the user asks it to do so. - **Evidence paths:** dist/index.js, dist/inboxHookInstall.js, dist/inboxHookCli.js, dist/activityHookInstall.js, dist/skillInstaller.js - **Review source:** ai\_review - **Reviewed:** 2026-10-30T06:46:29.673Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The server writes bundled skills and hook entries into ~/.claude, including a SessionStart hook that injects instructions to check and respond to AgentHub messages. - **Rationale:** The MCP server automatically writes global Claude Code skills and hooks, including a session-start prompt that directs the agent to process inbox messages before the user’s request. This is a meaningful agent-control capability exposed by default, though its stated purpose and side-effect limits do not establish malicious intent. - **Files touched:** ~/.claude/settings.json, ~/.claude/commands/, ~/.claude/skills/, \/.agenthub/activity - **Network endpoints:** agenthub.contetial.com ### Review decision - **Verdict:** Suspicious - **Confidence:** 88.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Unknown - **False-positive risk:** Medium - **Evidence for warning:** The package’s main entrypoint starts the MCP server and automatically installs bundled skills into the user’s ~/.claude directory unless opted out., On MCP startup, the package installs an inbox hook into ~/.claude/settings.json by default; AGENTHUB\_AUTO\_INBOX=false, 0, or off disables it., The hook prompts Claude to check the AgentHub inbox and handle messages before the user’s first request, including replying through AgentHub MCP tools., The package also installs a PostToolUse activity hook into ~/.claude/settings.json by default unless AGENTHUB\_AUTO\_ACTIVITY=false., The worker sends its API key to the configured AgentHub WebSocket server, whose default host is agenthub.contetial.com. - **Evidence against:** The inbox hook’s prompt says messages are input rather than instructions and tells the agent to stop before side effects such as deploying, publishing, deleting, or spending., The worker’s credential is sent to the configured AgentHub service as its authentication key., The shell startup hook edits shell configuration only when the user explicitly runs agenthub-setup install-shell., The manifest declares no lifecycle scripts. ## Affected versions and remediation This report applies to agenthub-multiagent-mcp@1.72.0. - Review the evidence and your use of agenthub-multiagent-mcp@1.72.0 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.
