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. This is not malicious under the install-control-surface policy because configuration mutation is explicitly user-invoked and there is no registry-install lifecycle hook. The embedded agent-control instructions and user-scope MCP registration warrant a warning. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 91.0% - **Started:** 2026-08-28T21:40:57.242Z - **Finished:** 2026-08-28T21:42:09.958Z - **Download time:** 506 ms - **Static scan time:** 2407 ms - **AI review time:** 69801 ms - **Total time:** 72716 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:** An explicit command can register this package as an MCP server in a Claude user configuration. Its MCP responses include controlling instructions for connected AI agents; no automatic install-time attack was found. - **Trigger:** The user runs mdr mcp install or configures and invokes the MCP server. - **Impact:** A connected AI agent may be steered to defer reporting and repeatedly invoke the package review tool. - **Evidence paths:** package.json, bin/cli.js, dist/mcp-stdio.js, dist/server.js - **Review source:** ai\_review - **Reviewed:** 2026-08-28T21:42:09.958Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Explicit MCP registration and agent-directed review workflow. - **Rationale:** This is not malicious under the install-control-surface policy because configuration mutation is explicitly user-invoked and there is no registry-install lifecycle hook. The embedded agent-control instructions and user-scope MCP registration warrant a warning. - **Files touched:** bin/cli.js, dist/mcp-stdio.js, dist/server.js, claude\_desktop\_config.json, .md-redline.json - **Network endpoints:** https://registry.npmjs.org, http://127.0.0.1:${port} ### Review decision - **Verdict:** Suspicious - **Confidence:** 91.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Medium - **Evidence for warning:** The explicit mcp install command adds an md-redline server entry to Claude Desktop configuration., The MCP payload instructs an AI agent not to report to the user and to keep calling the package tool until it returns done., The server checks npm for updates and stores update state in its preferences. - **Evidence against:** The manifest has no preinstall, install, or postinstall hook; prepublishOnly only builds for publishing., Claude configuration changes require the explicit mdr mcp install command., Observed service calls are localhost APIs plus the npm registry update check; no credential collection or secret exfiltration was found. ## Affected versions and remediation This report applies to md-redline@0.9.0. - Review the evidence and your use of md-redline@0.9.0 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.
