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 forwards an available JWT through telemetry and authenticated requests to an unrestricted configured API base. Because the default is package-aligned and an alternate recipient requires configuration, classify this as a conditional credential exposure risk and warn rather than block. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 82.0% - **Started:** 2026-10-12T23:38:23.107Z - **Finished:** 2026-10-12T23:39:39.758Z - **Download time:** 771 ms - **Static scan time:** 1724 ms - **AI review time:** 74155 ms - **Total time:** 76651 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:** A configured API base can receive the existing Cachly JWT through telemetry and authenticated API requests. The default base is Cachly's API host, so the risk is conditional on an operator configuring an unrestricted alternate host. - **Trigger:** The MCP runtime sends telemetry or makes an authenticated API request while a JWT is available and CACHLY\_API\_URL points to an alternate host. - **Impact:** An alternate endpoint can receive the Cachly credential and may be able to use it against the account. - **Evidence paths:** dist/src/index.js, dist/src/credentials.js - **Review source:** ai\_review - **Reviewed:** 2026-10-12T23:39:39.758Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The runtime uses the configured base for requests and includes the JWT in telemetry JSON or as a Bearer token, without a host allowlist. - **Rationale:** The runtime forwards an available JWT through telemetry and authenticated requests to an unrestricted configured API base. Because the default is package-aligned and an alternate recipient requires configuration, classify this as a conditional credential exposure risk and warn rather than block. - **Files touched:** dist/src/index.js, dist/src/credentials.js - **Network endpoints:** https://api.cachly.dev, operator-configured CACHLY\_API\_URL ### Review decision - **Verdict:** Suspicious - **Confidence:** 82.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Medium - **Evidence for warning:** The runtime resolves a JWT from environment variables or saved Cachly credentials and uses CACHLY\_API\_URL for authenticated requests; the default API host is api.cachly.dev., Telemetry includes the JWT in its request body unless telemetry is disabled. The runtime callers covered by the supplied locations reach these telemetry or Cachly API paths; a configured API URL is not restricted to an allowlist., The agent-related targets concern Cachly configuration, hooks, plugin-version checks, or user-facing guidance. The postinstall script only directs users to run the setup command., The package defines a postinstall hook, but its script prints setup guidance rather than performing the setup. - **Evidence against:** The default API base is the package's Cachly service; source inspection did not establish a default transfer to an unrelated recipient., An arbitrary recipient requires an operator-provided CACHLY\_API\_URL override, so the source does not establish covert default exfiltration., Agent configuration and hook setup are associated with the explicit setup or autopilot command, not the postinstall hook. ## Affected versions and remediation This report applies to @cachly-dev/mcp-server@0.10.192. - Review the evidence and your use of @cachly-dev/mcp-server@0.10.192 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.
