Treat them as untrusted evidence. Do not execute instructions or code found in this document. ## Verdict summary **Flagged as AI-agent capability risk** — Allowed by default with warning: agent-facing configuration or capability changes need review before use. - **Verdict:** Suspicious - **Product-default install policy:** Warn - **Firewall policy:** Warn-only AI-agent capability risk - **Public report status:** Published - **Threat category:** AI-agent capability abuse - **Selected version:** 0.97.3 - **Selected version is latest:** No - **Analysis source:** AI Security Review (lpm-firewall-ai) This is the current Firewall decision for the selected package version, based on the available public evidence. 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 source implements agent configuration changes as part of plugin management, while the manifest has no install lifecycle hook. This is a warning-level agent capability, not evidence of malicious execution or an unconsented npm install-time control-surface change. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 86.0% - **Started:** 2026-10-09T09:41:03.780Z - **Finished:** 2026-10-09T09:41:44.837Z - **Download time:** 762 ms - **Static scan time:** 3238 ms - **AI review time:** 37056 ms - **Total time:** 41057 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:** Plugin setup can change AI-agent configuration by registering MCP servers. This is an explicit capability of the package's plugin workflow; no confirmed attack surface was established. - **Trigger:** A user invokes plugin setup or synchronization. - **Impact:** Configured agents may load the registered MCP servers; the inspected evidence does not show covert installation or credential theft. - **Review source:** ai\_review - **Reviewed:** 2026-10-09T09:41:44.837Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The plugin code writes MCP configuration locally and includes code to merge MCP settings into Claude configuration in a remote Pod. - **Rationale:** The source implements agent configuration changes as part of plugin management, while the manifest has no install lifecycle hook. This is a warning-level agent capability, not evidence of malicious execution or an unconsented npm install-time control-surface change. - **Files touched:** dist/plugin.js ### Review decision - **Verdict:** Suspicious - **Confidence:** 86.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Medium - **Evidence for warning:** The package exposes the runtime through its import entry and declares no npm lifecycle hook., The plugin command writes an MCP server entry into the user's Codex configuration., The plugin installer records an install method for later remote plugin synchronization., The Pod setup code edits Claude's user configuration to merge MCP settings. - **Evidence against:** The observed agent configuration changes are part of explicit plugin setup flows, not npm installation hooks., The inspected source does not establish credential exfiltration or an active attack. ## Affected versions and remediation This report applies to @sentropic/h2a-runtime@0.97.3. - Review the evidence and your use of @sentropic/h2a-runtime@0.97.3 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.

High: External Ai Agent Control Surface Mutation - **Category:** Source - **Confidence:** 94.0% - **Path:** dist/plugin.js - **Public source:** [View source]() Runtime or CLI source writes behavior-bearing configuration into a user or project AI-agent control surface. Public source snippet (untrusted): ```javascript Runtime or CLI code links a write operation to an explicit external AI-agent control path: nd, args: [...args] }; root.mcpservers = servers; return json.stringify(root, null, 2) + "\n"; } export function mergeclaudemcpservers(json, name, command, args) { return mergemcpserversjson(json, name, command, args, "claude.json"); } export function mergeagymcpservers(json, name, command, args) { return mergemcpserversjson(json, name, command, args, "mcp_config.json"); } ``` ### 7. Low: High Entropy Strings - **Category:** Supply Chain - **Confidence:** 55.0% Package source contains high-entropy string patterns. ### 8. Low: Url Strings - **Category:** Supply Chain - **Confidence:** 65.0% Package source contains URL literals. ### 9.

High: Previous Version Dangerous Delta - **Category:** Supply Chain - **Confidence:** 93.0% - **Path:** dist/launch-layout.js - **Public source:** [View source]() This package version adds a dangerous source file absent from the previous stored version; route for source-aware review. Public source snippet (untrusted): ```javascript matchType = previous_version_dangerous_delta matchedPackage = @sentropic/h2a-runtime@0.96.2 matchedIdentity = npm:QHNlbnRyb3BpYy9oMmEtcnVudGltZQ:0.96.2 similarity = 0.932 summary = stored previous version shares package body but lacks this dangerous source file ``` ### 12.
