Cursor MCP JSON 配置示例

适合谁？

适合已经有 MCP 安装命令，但不知道 Cursor JSON 怎么写的用户。

~/.cursor/mcp.json

{
  "mcpServers": {
    "filesystem": {
      "command": "npx",
      "args": ["-y", "@modelcontextprotocol/server-filesystem", "./"]
    }
  }
}

Cursor expects MCP servers under a top-level mcpServers object.

{
  "mcpServers": {
    "filesystem": {
      "command": "npx",
      "args": ["-y", "@modelcontextprotocol/server-filesystem", "./"]
    }
  }
}

The first token becomes command. Everything after it becomes args.

Use stable names like filesystem, github, postgres, or browser.

A missing comma or quote can prevent Cursor from loading the server.

Putting the full command in command

Do not set command to the entire string. Use command: npx and args: [...] instead.

Wrong path

Make sure you are editing the Cursor config file used by your current profile.

What should command contain?

Only the executable, such as npx, uvx, docker, node, or python.

What should args contain?

All remaining command tokens, for example -y and the package name.
