Securing MCP Servers in Cursor: Configuration Best Practices
With 71% of companies now using generative AI in at least one business function, Cursor IDE enables organizations to access external data through Model Context Protocol servers. Yet over half (53%) of MCP servers rely on static API keys or Personal Access Tokens (PATs)—long-lived credentials that are rarely rotated and are high-impact if leaked. Recent critical vulnerabilities (CVE-2025-54136) expose remote code execution pathways, creating urgent pressure to secure MCP deployments before compliance teams block adoption. The MintMCP Gateway provides SOC 2 Type II certified infrastructure that transforms local MCP servers into production-ready services with centralized authentication, real-time monitoring, and compliance-ready audit trails—enabling enterprises to deploy AI coding assistants without creating shadow IT risks.
This article outlines actionable security configurations for Cursor's MCP server integration, covering client-side protections, enterprise gateway deployment, access controls, compliance requirements, and monitoring practices to ensure both security and operational efficiency.
