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 supports a warning for explicit agent configuration capabilities, including user-level MCP registration and Claude session hooks. No unconsented install-time attack or concrete malicious chain was identified. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 84.0% - **Started:** 2026-10-10T23:10:20.491Z - **Finished:** 2026-10-10T23:10:52.616Z - **Download time:** 1252 ms - **Static scan time:** 3301 ms - **AI review time:** 27572 ms - **Total time:** 32125 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:** The package can register MCP servers in user agent configuration files. This is a guarded capability reached through explicit plugin or enrollment operations; no install-time attack was identified. - **Trigger:** A user invokes the plugin management or enrollment functionality. - **Impact:** These changes can affect later agent sessions, but the inspected code does not establish an unconsented install-time mutation or other concrete attack. - **Evidence paths:** dist/plugin.js, dist/enroll.js - **Review source:** ai\_review - **Reviewed:** 2026-10-10T23:10:52.616Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Plugin registration merges or writes MCP server entries into agent configuration; Claude enrollment adds session hooks that invoke the package’s enrollment command. - **Rationale:** The source supports a warning for explicit agent configuration capabilities, including user-level MCP registration and Claude session hooks. No unconsented install-time attack or concrete malicious chain was identified. - **Files touched:** dist/plugin.js, dist/enroll.js ### Review decision - **Verdict:** Suspicious - **Confidence:** 84.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Medium - **Evidence for warning:** The plugin API documents an explicit command for adding MCP plugins and registering them with agent clients., The plugin code writes MCP configuration to the user-level Codex configuration file., Claude enrollment hooks run the package’s enrollment command at session start and end., The manifest defines no install lifecycle hook; its only script is build., The inspected PTY loader requires the declared node-pty dependency when invoked., The daemon writes a PID file as part of starting its local gateway. - **Evidence against:** The observed agent configuration changes belong to explicit plugin or enrollment operations; the inspected manifest does not run them during installation., The local Claude credential check is described as advisory, with no automatic action., The inspected source provides no evidence of credential exfiltration or an active attack. ## Affected versions and remediation This report applies to @sentropic/h2a-runtime@0.98.3. - Review the evidence and your use of @sentropic/h2a-runtime@0.98.3 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.
