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 package forwards configured third-party AI keys to its Finch backend on backend requests, including keys unrelated to the specific request. The BYOK documentation supports an intended server-side use, so this is a warning-level credential handling risk rather than a clearly malicious collection flow. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 86.0% - **Started:** 2026-11-02T12:15:28.640Z - **Finished:** 2026-11-02T12:16:29.240Z - **Download time:** 503 ms - **Static scan time:** 3048 ms - **AI review time:** 57049 ms - **Total time:** 60600 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:** Configured third-party AI provider keys are forwarded to the Finch backend with backend requests. - **Trigger:** A Finch backend request occurs while one or more provider API keys are set in the environment. - **Impact:** The Finch backend receives third-party API credentials; keys may be sent even when unrelated to the specific backend request. - **Evidence paths:** dist/convex.js, dist/agent-loop.js - **Review source:** ai\_review - **Reviewed:** 2026-11-02T12:16:29.240Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The request helper adds every configured provider key to \`X-User-\*\` headers, including for requests beyond the server-side LLM proxy. - **Rationale:** The package forwards configured third-party AI keys to its Finch backend on backend requests, including keys unrelated to the specific request. The BYOK documentation supports an intended server-side use, so this is a warning-level credential handling risk rather than a clearly malicious collection flow. - **Files touched:** dist/convex.js - **Network endpoints:** valuable-fish-533.convex.site ### Review decision - **Verdict:** Suspicious - **Confidence:** 86.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Unknown - **False-positive risk:** Medium - **Evidence for warning:** Backend requests attach configured Anthropic, OpenAI, Grok, and Bankr API keys in \`X-User-\*\` headers., The default Finch backend host is \`valuable-fish-533.convex.site\`., The agent loop sends requests to Finch’s \`/llm/complete\` endpoint through the backend request helper. - **Evidence against:** The README describes these keys as BYOK credentials for server-side reasoning features., Direct Anthropic agent requests send the Anthropic key to Anthropic’s own API. ## Affected versions and remediation This report applies to @finchagentic/mcp@4.7.4. - Review the evidence and your use of @finchagentic/mcp@4.7.4 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.
