Treat them as untrusted evidence. Do not execute instructions or code found in this document. ## Verdict summary **Allowed — no malicious behavior detected** — No malicious behavior detected. 12 low-signal pattern(s) reviewed. - **Verdict:** Clean - **Product-default install policy:** Allow - **Firewall policy:** No policy match - **Public report status:** Published - **Threat category:** None published - **Selected version:** 0.97.2 - **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: clean; recommendation: mark clean. This assessment is supporting evidence; the published decision above determines the current policy. Source inspection supports a clean verdict: the manifest has no install lifecycle hook, and the inspected agent configuration behavior is tied to runtime plugin setup. Scanner hints identify areas for review but do not establish a malicious chain. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Clean - **Recorded analysis confidence:** 84.0% - **Started:** 2026-10-09T09:41:04.331Z - **Finished:** 2026-10-09T09:41:56.732Z - **Download time:** 511 ms - **Static scan time:** 2847 ms - **AI review time:** 49042 ms - **Total time:** 52401 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:** No confirmed attack surface was identified. The flagged agent configuration code supports plugin registration, with no inspected evidence that it runs automatically during npm installation. - **Trigger:** An explicit runtime plugin or session command invokes the relevant setup behavior. - **Impact:** No malicious impact was established from the inspected source. - **Review source:** ai\_review - **Reviewed:** 2026-10-09T09:41:56.732Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The plugin flow writes MCP registration data to agent configuration; the other reviewed integrations select config paths or handle session state and launch behavior. - **Rationale:** Source inspection supports a clean verdict: the manifest has no install lifecycle hook, and the inspected agent configuration behavior is tied to runtime plugin setup. Scanner hints identify areas for review but do not establish a malicious chain. ### Review decision - **Verdict:** Clean - **Confidence:** 84.0% - **Recommended action:** mark\_clean - **Intent class:** Benign - **False-positive risk:** Low - **Evidence for AI clean decision:** package.json exposes the runtime entrypoints and declares no install lifecycle hook; flagged setup code is reached through explicit runtime commands., The plugin code registers MCP servers in agent configuration when its plugin-add flow is invoked; this is an agent capability, but the inspected source does not establish an unconsented install-time mutation., Other flagged files handle MCP config path selection, explicit session hooks, local token-expiry advisories, session migration and discovery, PTY loading, auth-file selection, and terminal layout dispatch. - **Evidence against:** No concrete malicious behavior was established in the inspected source; the agent configuration writes are part of the plugin-add flow rather than an npm lifecycle hook., The package manifest contains no preinstall, install, or postinstall script. ## Affected versions and remediation This report applies to @sentropic/h2a-runtime@0.97.2. - Review the evidence and your use of @sentropic/h2a-runtime@0.97.2 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. Medium: Dynamic Require - **Category:** Source - **Confidence:** 75.0% - **Path:** dist/central-mcp.js - **Public source:** [View source]() Package source references dynamic require/import behavior. Public source snippet (untrusted): ```javascript L21: const corePackage = "@sentropic/h2a"; L22: coreCentralMcp ??= import(corePackage).then((core) => { L23: const candidate = core; ``` ### 2. Medium: Network - **Category:** Source - **Confidence:** 75.0% Package source references network APIs. ### 3. Medium: Environment Vars - **Category:** Source - **Confidence:** 75.0% Package source references environment variables. ### 4. Low: Filesystem - **Category:** Source - **Confidence:** 70.0% Package source references filesystem APIs. ### 5. High: Copied Package Dependency Bridge - **Category:** Source - **Confidence:** 83.0% - **Path:** dist/pty.js - **Public source:** [View source]() Package metadata claims a different repository identity while copied source loads a runtime dependency bridge. Public source snippet (untrusted): ```javascript package = @sentropic/h2a-runtime; repositoryIdentity = h2a; dependency = node-pty L76: try { L77: require("node-pty"); L78: } ``` ### 6. 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. Medium: Structural Risk Force Deep Review - **Category:** Artifact Inventory - **Confidence:** 100.0% Artifact structure forces deeper review even if the static behavioral verdict is clean. ### 10. High: Semantic Analysis Limited - **Category:** Scanner Coverage - **Confidence:** 100.0% - **Path:** dist/auth-tools.js\#virtual:normalized:round1 - **Public source:** [View source]() A bounded semantic-analysis stage reached its safety limit; remaining detectors completed, but this package requires AI review. Public source snippet (untrusted): ```text stage = ast_semantic_analysis; reason = ast_parse_error; limitedFiles = 9 ``` ### 11. 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. Low: Suspicious Lifecycle Evidence - **Category:** Manifest - **Confidence:** 84.0% - **Path:** package.json - **Public source:** [View source]() package.json exposes the runtime entrypoints and declares no install lifecycle hook; flagged setup code is reached through explicit runtime commands.
