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. This is a real cloud-controlled AI-agent capability with credential-handling and persistence implications, but the sensitive credential upload is explicitly user-invoked and the install hook is limited to unpacking local tools. The source does not establish covert install-time exfiltration or an unconsented foreign agent-control-surface mutation. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 88.0% - **Started:** 2026-09-05T01:27:15.957Z - **Finished:** 2026-09-05T01:28:35.526Z - **Download time:** 1777 ms - **Static scan time:** 5247 ms - **AI review time:** 72544 ms - **Total time:** 79569 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:** When the user starts the CLI, it authenticates to thalamus.etai.app, retrieves cloud-managed MCP definitions, and supplies them to Claude. Those definitions can specify local commands and arguments, leaving the package service able to extend the local agent session. - **Trigger:** A user runs the thalamus CLI after authenticating. - **Impact:** A compromised or malicious package service could cause a user's Claude session to start attacker-selected MCP tools; the explicit connect command can also upload OAuth credentials to that service. - **Evidence paths:** package.json, scripts/unpack-tools.cjs, dist/index.cjs, dist/types-Cdl8Y8g9.mjs - **Review source:** ai\_review - **Reviewed:** 2026-09-05T01:28:35.526Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Cloud-delivered MCP command configuration and detached daemon startup. - **Rationale:** This is a real cloud-controlled AI-agent capability with credential-handling and persistence implications, but the sensitive credential upload is explicitly user-invoked and the install hook is limited to unpacking local tools. The source does not establish covert install-time exfiltration or an unconsented foreign agent-control-surface mutation. - **Files touched:** scripts/unpack-tools.cjs, tools/unpacked, ~/.thalamus, ~/.claude/.credentials.json - **Network endpoints:** https://thalamus.etai.app, https://api.anthropic.com ### Review decision - **Verdict:** Suspicious - **Confidence:** 88.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Medium - **Evidence for warning:** The install hook extracts bundled archives and marks extracted binaries executable., The explicit connect command sends an Anthropic OAuth token object to the package's default cloud service., A cloud response supplies MCP server definitions, including commands and arguments, which are passed into a Claude launch configuration., Normal CLI startup detaches a background daemon after authentication. - **Evidence against:** The install hook only invokes the local archive unpacker; it contains no network request or foreign agent-config write., Credential upload is behind the explicit \`thalamus connect claude\` command., No runtime dependency on thalamus itself is declared., The existing Claude OAuth token is used for an Anthropic usage request, not shown being sent to the package service. ## Affected versions and remediation This report applies to thalamus@1.3.0. - Review the evidence and your use of thalamus@1.3.0 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.
