    "stability": {
      "command": "npx",
      "args": [
        "-y",
        "mcp-server-stability-ai"
      ],
      "env": {

Gotchas

Cursor keeps MCP servers under an "mcpServers" object in ~/.cursor/mcp.json for global use, and also reads a project-scoped .cursor/mcp.json so a repository can ship its own servers. Remote servers are configured with a bare "url" field and connect natively, with OAuth handled in-app when a server requires it.
