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 API keys to its backend without clearly disclosing that they accompany general backend requests. The setup wizard does ask users to configure keys for Finch features, so the evidence supports a warning for insufficiently bounded credential forwarding rather than a confident malicious verdict. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 89.0% - **Started:** 2026-11-02T12:15:00.941Z - **Finished:** 2026-11-02T12:16:28.892Z - **Download time:** 253 ms - **Static scan time:** 2450 ms - **AI review time:** 85248 ms - **Total time:** 87951 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 LLM credentials are attached to Finch backend requests, creating an insufficiently disclosed credential exposure risk. - **Trigger:** A Finch backend request occurs while one or more provider API keys are present in the environment. - **Impact:** The Finch backend receives third-party credentials even when the request is not itself an LLM call, allowing use beyond the provider-specific routing users may expect. - **Evidence paths:** dist/convex.js, dist/cli.js, dist/agent-loop.js - **Review source:** ai\_review - **Reviewed:** 2026-11-02T12:16:28.892Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** \`dist/convex.js\` adds each configured provider key to an \`X-User-\*\` header; requests default to the Finch Convex host. - **Rationale:** The package forwards configured third-party API keys to its backend without clearly disclosing that they accompany general backend requests. The setup wizard does ask users to configure keys for Finch features, so the evidence supports a warning for insufficiently bounded credential forwarding rather than a confident malicious verdict. - **Network endpoints:** https://valuable-fish-533.convex.site, https://api.anthropic.com ### Review decision - **Verdict:** Suspicious - **Confidence:** 89.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Unknown - **False-positive risk:** Medium - **Evidence for warning:** \`dist/convex.js\` copies configured Anthropic, OpenAI, Grok and Bankr keys from environment variables into \`X-User-\*\` request headers., The default backend receiving those requests is \`https://valuable-fish-533.convex.site\`, unless \`FINCH\_CONVEX\_URL\` overrides it., The setup wizard lets users provide a provider key for Finch shell and MCP calls, but does not disclose that configured keys are attached to backend requests generally., The agent loop also sends an Anthropic key directly to \`api.anthropic.com\`, consistent with the package's provider-routing function. - **Evidence against:** The setup wizard makes provider keys optional and prompts users to choose a provider and enter its key., Provider keys have an apparent intended use for Finch's LLM features, and the agent loop routes an Anthropic key to Anthropic's own API. ## Affected versions and remediation This report applies to @finchagentic/mcp@4.7.0. - Review the evidence and your use of @finchagentic/mcp@4.7.0 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.
