Findings for this version do not establish the status of other versions. AI assessment: malicious; recommendation: publish block. This assessment is supporting evidence; the published decision above determines the current policy. The shared Finch backend client automatically forwards configured third-party provider keys on ordinary tool requests, not only on requests that need those keys for the documented reasoning features. This is credential exfiltration to the package vendor without clear, scoped consent. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 97.0% - **Started:** 2026-11-02T12:15:44.836Z - **Finished:** 2026-11-02T12:16:47.935Z - **Download time:** 759 ms - **Static scan time:** 2762 ms - **AI review time:** 59577 ms - **Total time:** 63099 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 credentials are sent to Finch's backend with ordinary backend requests. - **Trigger:** A user invokes a tool that calls the Finch backend while one or more provider API keys are configured in the environment. - **Impact:** Finch's backend receives credentials for third-party AI services even on requests unrelated to the documented server-side reasoning features. - **Evidence paths:** dist/convex.js, dist/tools/memory.js, README.md - **Review source:** ai\_review - **Reviewed:** 2026-11-02T12:16:47.935Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The shared backend client unconditionally copies configured Anthropic, OpenAI, Grok, and Bankr keys into request headers sent to the Finch Convex endpoint. - **Attack narrative:** When a backend-backed tool runs, the shared client sends any configured Anthropic, OpenAI, Grok, or Bankr API keys to Finch's Convex endpoint. This happens for ordinary operations such as listing memory, although the README describes those keys as needed for specific server-side reasoning features. The keys are therefore disclosed to the package vendor beyond the stated feature context. - **Rationale:** The shared Finch backend client automatically forwards configured third-party provider keys on ordinary tool requests, not only on requests that need those keys for the documented reasoning features. This is credential exfiltration to the package vendor without clear, scoped consent. - **Network endpoints:** https://valuable-fish-533.convex.site ### Review decision - **Verdict:** Malicious - **Confidence:** 97.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for block:** The backend client defaults to https://valuable-fish-533.convex.site., Every Finch backend request attaches any configured Anthropic, OpenAI, Grok, and Bankr API keys as headers., Ordinary memory operations call the same backend client, so key forwarding is not limited to LLM reasoning requests., The README describes these keys as needed for specific server-side reasoning features, not as credentials to include with all backend requests. - **Evidence against:** The README describes the keys as BYOK for server-side reasoning, indicating a stated product use for them., The forwarding occurs on backend requests triggered by tool calls, rather than during package installation. ## Affected versions and remediation This report applies to @finchagentic/mcp@4.7.5. - Avoid installing @finchagentic/mcp@4.7.5. Remove it from direct dependencies and check your lockfile for transitive copies. - Choose an independently verified alternative or release. This report does not establish that other versions are safe. - If this version ran, investigate the affected machine and build environment. Rotate credentials it could access and rebuild from a trusted environment. ## Public findings ### 1.
