Cursor's MCP (Multi-Command Protocol) servers, when integrated, transform the agent from a text source into an execution process. Security best practices dictate that local servers should operate with the same privileges as the client, meaning a compromised server or malicious command could potentially access sensitive files like SSH keys. Cursor manages MCP configurations through project-specific (.cursor/mcp.json) and global (~/.cursor/mcp.json) files, with project settings taking precedence. The platform advises against hardcoding secrets, recommending environment variables or restricted API keys with minimal permissions for secure secret management. AI
