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 runtime places an existing service JWT in telemetry bodies, with only an opt-out guard and a configurable destination. Because the default recipient is the package's intended service, this supports a warning for conditional credential exposure rather than a block. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 86.0% - **Started:** 2026-10-16T14:12:36.083Z - **Finished:** 2026-10-16T14:14:06.226Z - **Download time:** 1010 ms - **Static scan time:** 1834 ms - **AI review time:** 87298 ms - **Total time:** 90143 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:** Telemetry can disclose the configured Cachly JWT and user fingerprint in an event body. This creates a credential exposure risk when telemetry is enabled. - **Trigger:** A runtime telemetry event occurs while CACHLY\_NO\_TELEMETRY is not set to 1. - **Impact:** The telemetry recipient receives the JWT alongside event data; a configured alternate API URL also receives it. - **Evidence paths:** dist/src/index.js, dist/src/credentials.js - **Review source:** ai\_review - **Reviewed:** 2026-10-16T14:14:06.226Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The telemetry request includes the JWT in its JSON body and sends to the configured API URL, which defaults to api.cachly.dev. - **Rationale:** The runtime places an existing service JWT in telemetry bodies, with only an opt-out guard and a configurable destination. Because the default recipient is the package's intended service, this supports a warning for conditional credential exposure rather than a block. - **Network endpoints:** https://api.cachly.dev/api/v1/telemetry/mcp ### Review decision - **Verdict:** Suspicious - **Confidence:** 86.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Medium - **Evidence for warning:** The runtime obtains a Cachly JWT from environment variables, saved credentials, or the Cachly entry in .mcp.json., The telemetry helper sends the JWT and user fingerprint in the request body; telemetry is disabled only when CACHLY\_NO\_TELEMETRY is set to 1., Telemetry uses CACHLY\_API\_URL when configured and otherwise sends to api.cachly.dev., The postinstall hook only prints setup instructions and performs no file or network operation. - **Evidence against:** The default telemetry recipient, api.cachly.dev, is also the package's intended API service., The telemetry request is guarded by an explicit no-telemetry environment setting. ## Affected versions and remediation This report applies to @cachly-dev/mcp-server@0.10.203. - Review the evidence and your use of @cachly-dev/mcp-server@0.10.203 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.
