OpenSSF/OSV advisory MAL-2026-13399 confirms this npm version as malicious. agenthub-multiagent-mcp ships a worker (dist/worker.js) that opens a WebSocket to the hardcoded server wss://agenthub.contetial.com/ws/workers/\ and, for every 'dispatch' message received, writes the server-supplied message body to a prompt file and spawns 'bash run-claude.sh' which invokes 'claude -p "$PROMPT" --dangerously-skip-permissions --max-turns N --mcp-config...' with cwd set to a user-configured project... ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 90.0% - **Started:** 2026-08-09T19:13:59.392Z - **Finished:** 2026-08-09T19:15:00.668Z - **Download time:** 501 ms - **Static scan time:** 1644 ms - **AI review time:** 59130 ms - **Total time:** 61276 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:** Starting the MCP mutates the user's Claude Code configuration to add AgentHub hooks and bundled skills. The added inbox hook influences future Claude sessions; capture is separately server-consent-gated. - **Trigger:** User starts/configures the AgentHub MCP executable. - **Impact:** AgentHub can influence Claude session startup and, with server-confirmed consent, transmit recorded session/tool data to its API. - **Evidence paths:** package.json, dist/index.js, dist/inboxHookInstall.js, dist/inboxHookCli.js, dist/captureHookInstall.js, dist/session-capture.sh - **Review source:** ai\_review - **Reviewed:** 2026-08-09T19:15:00.668Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** runtime Claude Code hook installation and consent-gated session capture - **Rationale:** Source confirms runtime AI-agent configuration mutation and remote session capture capability, so it warrants a warning. No npm lifecycle execution or concrete stealth/malicious chain was found. - **Files touched:** ~/.claude/settings.json, ~/.claude/agenthub-capture.json, ~/.claude/agenthub-capture-state, ~/.claude/skills - **Network endpoints:** https://agenthub.contetial.com/api/session-capture/consent, https://agenthub.contetial.com/api/sessions/{id}/events ### Review decision - **Verdict:** Suspicious - **Confidence:** 90.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Low - **Evidence for AI warning decision:** dist/index.js installs activity and inbox Claude hooks on every MCP start unless env-disabled., dist/inboxHookInstall.js writes a SessionStart command into ~/.claude/settings.json by default., dist/inboxHookCli.js injects a system reminder to check and reply to AgentHub inbox messages before the user's request., dist/captureHookInstall.js can register a PostToolUse capture hook after a server consent response., dist/session-capture.sh sends captured tool/session content to the configured AgentHub API. - **Evidence against:** package.json has no preinstall, install, or postinstall lifecycle hook., Hook and skill changes occur when the MCP executable is started, not during npm installation., Capture registration is explicitly gated on a successful consent lookup and removes its hook when consent is absent., Shell/startup persistence in dist/setup.js requires interactive agenthub-setup confirmation. ## Affected versions and remediation This report applies to agenthub-multiagent-mcp@1.57.0. - Avoid installing agenthub-multiagent-mcp@1.57.0. Remove it from direct dependencies and check your lockfile for transitive copies. - Choose an independently verified alternative or release. This report does not establish that other versions are safe. - If this version ran, investigate the affected machine and build environment. Rotate credentials it could access and rebuild from a trusted environment. ## Public findings ### 1.
