Firewall keeps the version blocked under its trusted-intelligence policy. An AI recommendation to allow or warn does not override that advisory. AI assessment: suspicious; recommendation: downgrade to warn. This assessment is supporting evidence; the published decision above determines the current policy. At runtime, the MCP server exposes unrestricted host shell execution. A connected MCP client can invoke it with the server process's permissions. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 95.0% - **Started:** 2026-09-23T01:54:28.207Z - **Finished:** 2026-09-23T01:55:05.319Z - **Download time:** 758 ms - **Static scan time:** 18 ms - **AI review time:** 36334 ms - **Total time:** 37112 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:** At runtime, the MCP server exposes unrestricted host shell execution. A connected MCP client can invoke it with the server process's permissions. - **Trigger:** User runs mcp-demo and an MCP client invokes exec\_command. - **Impact:** Commands supplied by a client can read, modify, or execute resources accessible to the host process. - **Evidence paths:** package.json, dist/index.js - **Review source:** ai\_review - **Reviewed:** 2026-09-23T01:55:05.319Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** MCP-exposed arbitrary shell command execution via child\_process.exec - **Rationale:** The shipped runtime deliberately provides unrestricted shell execution to MCP clients, a dangerous capability with concrete host impact. It has no active install-time mutation or autonomous exfiltration behavior, so a warning is appropriate rather than a block. - **Files touched:** dist/index.js ### Review decision - **Verdict:** Suspicious - **Confidence:** 95.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Low - **Evidence for block:** Runtime MCP tool accepts an arbitrary command string and passes it directly to child\_process.exec., The package is an executable MCP server, so a connected client can invoke the shell-capable tool., A remote binary download command exists only in a comment and is inert. - **Evidence against:** No preinstall, install, or postinstall hook is declared; prepare only runs the build command., No active network, credential-harvesting, file-write, or persistence logic was found in the shipped code. ## Affected versions and remediation This report applies to @httttt/mcp-demo@1.1.0. - Avoid installing @httttt/mcp-demo@1.1.0. 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.
