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. Runtime telemetry can forward the current Cachly JWT to an operator-configured API base without a recipient allowlist. The default recipient is the package’s Cachly API host, so the inspected behavior supports a conditional credential exposure warning, not a block. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 88.0% - **Started:** 2026-10-19T22:22:10.406Z - **Finished:** 2026-10-19T22:23:39.445Z - **Download time:** 775 ms - **Static scan time:** 1791 ms - **AI review time:** 86472 ms - **Total time:** 89039 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:** Runtime telemetry can send the current Cachly JWT to a configurable API base. This creates conditional credential exposure if that base is set to an unrestricted recipient; the default is the package’s Cachly API host. - **Trigger:** A telemetry event during runtime, including selected instance or Redis errors; general telemetry calls are skipped when CACHLY\_NO\_TELEMETRY is set to 1. - **Impact:** A recipient selected through the API base can receive the Cachly credential. The inspected source supports a warning about conditional exposure, not a claim of malicious theft. - **Evidence paths:** dist/src/index.js, dist/src/credentials.js - **Review source:** ai\_review - **Reviewed:** 2026-10-19T22:23:39.445Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The runtime selects CACHLY\_API\_URL or defaults to https://api.cachly.dev, then sends telemetry containing the JWT. The source does not enforce a recipient allowlist for an overridden base. - **Rationale:** Runtime telemetry can forward the current Cachly JWT to an operator-configured API base without a recipient allowlist. The default recipient is the package’s Cachly API host, so the inspected behavior supports a conditional credential exposure warning, not a block. - **Network endpoints:** https://api.cachly.dev/api/v1/telemetry/mcp, CACHLY\_API\_URL/api/v1/telemetry/mcp ### Review decision - **Verdict:** Suspicious - **Confidence:** 88.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Medium - **Evidence for warning:** The runtime defaults its API base to api.cachly.dev and lets CACHLY\_API\_URL replace it., Telemetry sends the current JWT to that base on selected error paths, and a general telemetry sender includes the JWT in its request body unless CACHLY\_NO\_TELEMETRY is set to 1., The JWT can come from environment variables, saved Cachly credentials, or the Cachly MCP configuration., The inspected handler operations use Cachly instance and cache data for MCP tool behavior; they do not establish a separate attack., The postinstall hook prints setup guidance; the credential forwarding is in runtime code. - **Evidence against:** The default telemetry recipient is the package’s Cachly API host., The postinstall hook does not perform the runtime credential transfer. ## Affected versions and remediation This report applies to @cachly-dev/mcp-server@0.10.211. - Review the evidence and your use of @cachly-dev/mcp-server@0.10.211 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.
