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 configurable harvest endpoint can receive an ambient Anthropic credential without a destination allowlist, creating conditional credential exposure. Harvest execution is gated, and the source does not establish a package-controlled unrelated recipient or a malicious install action. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 91.0% - **Started:** 2026-10-09T10:08:54.187Z - **Finished:** 2026-10-09T10:09:59.810Z - **Download time:** 7955 ms - **Static scan time:** 9297 ms - **AI review time:** 48366 ms - **Total time:** 65623 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:** When harvesting is enabled, the package sends session-derived data to a configurable model endpoint and may attach an ambient Anthropic API key. - **Trigger:** A Stop or PreCompact harvest invokes extraction with harvest enabled. - **Impact:** If the configured endpoint is not the intended Anthropic service, the ambient key can be exposed to that endpoint. No evidence shows the package itself chooses an unrelated recipient. - **Evidence paths:** hooks-core/harvest.mjs - **Review source:** ai\_review - **Reviewed:** 2026-10-09T10:09:59.810Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** For nonlocal Anthropic-dialect endpoints, credential selection falls back to ANTHROPIC\_API\_KEY; the request sends that credential to the configured endpoint. - **Rationale:** The configurable harvest endpoint can receive an ambient Anthropic credential without a destination allowlist, creating conditional credential exposure. Harvest execution is gated, and the source does not establish a package-controlled unrelated recipient or a malicious install action. - **Files touched:** hooks-core/harvest.mjs - **Network endpoints:** https://api.anthropic.com/v1/messages, TOKEN\_OPTIMIZER\_HARVEST\_ENDPOINT ### Review decision - **Verdict:** Suspicious - **Confidence:** 91.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Medium - **Evidence for warning:** hooks-core/harvest.mjs accepts a caller-configurable endpoint and forwards ANTHROPIC\_API\_KEY to nonlocal Anthropic-dialect destinations., The harvest sends its digest in an HTTP POST; extraction proceeds only when harvestEnabled() is true., scripts/postinstall.cjs requires TOKEN\_OPTIMIZER\_AUTO\_INSTALL before invoking setup. - **Evidence against:** hooks-core/harvest.mjs describes raw transcript transmission as opt-in; its default is a structured digest., The postinstall script’s automatic setup is explicitly gated by TOKEN\_OPTIMIZER\_AUTO\_INSTALL. ## Affected versions and remediation This report applies to @ooples/token-optimizer-mcp@7.4.2. - Review the evidence and your use of @ooples/token-optimizer-mcp@7.4.2 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.
