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 performs undisclosed runtime telemetry: it reports a persistent device identifier at startup and sends full prompts and answers to Tencent logging when relevant tools are used. This supports a warning for telemetry, but the observed endpoints belong to the package vendor and the reports are tied to its service and explicit tool use, so the evidence does not establish malicious behavior. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 94.0% - **Started:** 2026-11-03T13:17:02.445Z - **Finished:** 2026-11-03T13:18:51.639Z - **Download time:** 7881 ms - **Static scan time:** 594 ms - **AI review time:** 100718 ms - **Total time:** 109194 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:** Undisclosed runtime telemetry sends a persistent device identifier and user-provided prompts and answers to Tencent reporting endpoints. - **Trigger:** Server startup reports configuration telemetry; invoking search\_trtc\_knowledge or finalize\_answer reports prompts and answers. - **Impact:** The service receives a stable device identifier that can encode host and username details, as well as consultation content that may contain sensitive information. - **Evidence paths:** server-config.js, utils/get-device-identifier.js, utils/report-es-client.js, utils/report-cls-client.js, tools/common/search\_trtc\_knowledge.js, tools/common/finalize\_answer.js - **Review source:** ai\_review - **Reviewed:** 2026-11-03T13:18:51.639Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The package derives a fallback SDKAppID from a stored device identifier, reports it at startup, and maps prompt and answer fields into telemetry requests. - **Rationale:** The package performs undisclosed runtime telemetry: it reports a persistent device identifier at startup and sends full prompts and answers to Tencent logging when relevant tools are used. This supports a warning for telemetry, but the observed endpoints belong to the package vendor and the reports are tied to its service and explicit tool use, so the evidence does not establish malicious behavior. - **Files touched:** ~/.mcp/identifier - **Network endpoints:** ap-nanjing.cls.tencentcs.com, webim.tim.qq.com ### Review decision - **Verdict:** Suspicious - **Confidence:** 94.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Unknown - **False-positive risk:** Medium - **Evidence for warning:** On server startup, missing or invalid SDKAPPID is replaced with a device identifier, then reported as mcp\_config., The fallback identifier is derived from host, platform, architecture, and username information., When search\_trtc\_knowledge is called, the original prompt is sent to the CLS reporting function; that function posts telemetry to ap-nanjing.cls.tencentcs.com., When finalize\_answer is called, the answer and prompt are sent to the same reporting function. - **Evidence against:** The package presents itself as a Tencent RTC documentation retrieval and integration MCP server, and its local chunker source performs text segmentation., The manifest contains no lifecycle scripts; prompt and answer reports are triggered by explicit tool calls, while the startup report carries configuration telemetry. ## Affected versions and remediation This report applies to @tencent-rtc/mcp@1.8.3. - Review the evidence and your use of @tencent-rtc/mcp@1.8.3 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.
