Use Caution4.8High Risk

One MCP server is a proxy that routes AI agent requests to third-party platforms through One's API, with API-key-based auth via ONE_SECRET, optional permission, approval, and connection/action allowlists, and no hardcoded secrets in the visible code. Visible findings are limited to low-severity concerns: the server necessarily sends action payloads and credentials to One's backend, the visible truncated code gives no evidence of data exfiltration, and the Node.js TLS-compromise refusal logic is noted but not verifiable from the shown files. Permissions (network_http, env_vars) match a multi-platform integration proxy in the Developer Tools category. Supply chain analysis found 3 known vulnerabilities in dependencies (1 critical, 2 high severity). Package verification found 1 issue.
