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. Source establishes a real high-impact agent shell capability and install-time native payload delivery, warranting a warning. It does not establish malicious intent or a concrete unconsented attack chain. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 90.0% - **Started:** 2026-08-09T22:03:36.976Z - **Finished:** 2026-08-09T22:04:39.466Z - **Download time:** 1026 ms - **Static scan time:** 9705 ms - **AI review time:** 51758 ms - **Total time:** 62490 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:** Installation fetches verified native browser and shell MCP binaries. At runtime, its agent-facing background-bash service can execute shell commands. - **Trigger:** npm postinstall; later Negotium runtime/MCP tool use - **Impact:** A compromised or unsafe agent session could execute commands with the runtime user's privileges. - **Evidence paths:** package.json, install-browser-rs.mjs, install-bash-rs.mjs, dist/runtime/src/mcp/background-bash-server.ts, dist/mcp-factories.js, dist/runtime/src/platform/mcp-config.ts - **Review source:** ai\_review - **Reviewed:** 2026-08-09T22:04:39.466Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** verified native-binary staging plus agent-accessible shell execution - **Rationale:** Source establishes a real high-impact agent shell capability and install-time native payload delivery, warranting a warning. It does not establish malicious intent or a concrete unconsented attack chain. - **Files touched:** install-browser-rs.mjs, install-bash-rs.mjs, dist/runtime/src/mcp/background-bash-server.ts, dist/mcp-factories.js - **Network endpoints:** https://github.com/maestrojeong/browser-rs-mcp/releases/download/v0.1.19, https://github.com/maestrojeong/bash-rs-mcp/releases/download/v0.1.2, http://127.0.0.1 ### Review decision - **Verdict:** Suspicious - **Confidence:** 90.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Low - **Evidence for warning:** package.json runs two postinstall scripts., install-browser-rs.mjs downloads and installs an executable to ~/.negotium., install-bash-rs.mjs downloads and installs an executable to ~/.negotium., dist/runtime/src/mcp/background-bash-server.ts executes bash -c commands., dist/mcp-factories.js provides a vault-backed shell-command facility. - **Evidence against:** Postinstall downloads use fixed GitHub release URLs and SHA-256 verification., No source evidence of credential exfiltration or arbitrary external endpoint., Runtime MCP endpoints shown are loopback-only and capability-checked., No install-time AI-agent configuration mutation found. ## Affected versions and remediation This report applies to negotium@0.2.13. - Review the evidence and your use of negotium@0.2.13 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.
