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 sends runtime interaction data, including tool inputs and full API outputs, to its own service without clearly disclosing the collected contents or offering an opt-out. This is suspicious telemetry rather than a clear malicious attack because the destination is the package's own service and logging is triggered by user-invoked tools. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 94.0% - **Started:** 2026-11-01T04:15:47.122Z - **Finished:** 2026-11-01T04:16:19.580Z - **Download time:** 1028 ms - **Static scan time:** 303 ms - **AI review time:** 31126 ms - **Total time:** 32458 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 MCP tool inputs and outputs to Apitree, including potentially identifying or sensitive content. - **Trigger:** A user invokes tools such as search\_apis or call\_api. - **Impact:** Tool queries, API responses, and other interaction data may be retained by the vendor without a disclosed way to disable collection. - **Evidence paths:** dist/lib/nexus-client.js, dist/tools.js, README.md - **Review source:** ai\_review - **Reviewed:** 2026-11-01T04:16:19.580Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The tool handlers call logInteraction, which posts serialized input and output records to the configured Apitree API base URL; the default agent-log endpoint is https://apitree.ai/api/v1/agent-log. - **Rationale:** The package sends runtime interaction data, including tool inputs and full API outputs, to its own service without clearly disclosing the collected contents or offering an opt-out. This is suspicious telemetry rather than a clear malicious attack because the destination is the package's own service and logging is triggered by user-invoked tools. - **Network endpoints:** https://apitree.ai/api/v1/agent-log, APITREE\_API\_URL/api/v1/agent-log ### Review decision - **Verdict:** Suspicious - **Confidence:** 94.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Medium - **Evidence for warning:** The runtime logger posts interaction records to the Apitree agent-log endpoint., The logger serializes tool inputs and outputs along with session and context fields., User-requested API searches log the search intent and returned results., User-requested API calls log the full API response, which may contain sensitive data., The README mentions telemetry identifiers but does not disclose logging of tool inputs and outputs or provide an opt-out. - **Evidence against:** The entry point registers tools and starts an MCP stdio server; it does not invoke the logging calls directly., The package has no install lifecycle scripts., The logger sends data to the package's own Apitree service, not an unrelated collector. ## Affected versions and remediation This report applies to @apitreedev/mcp-server@0.3.5. - Review the evidence and your use of @apitreedev/mcp-server@0.3.5 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.
