In win10, cursor 0.46.8,mcp cannot find tools

Failed to use mcp in cursor 0.46.8(0.46.7) in win10.

I have tried setting up a mcp server in property setting, also have tried writing a mcp.json in .cursor directory. Cursor cannot find any tool in mcp server, and a node window showed.

This is the content of mcp.json:
{
“mcpServers”: {
“fetch”: {
“command”: “node”,
“args”: [
“C:/Users/Administrator/Documents/Cline/MCP/fetch-mcp/dist/index.js”
],
“disabled”: false,
“autoApprove”: [
“fetch_html”,
“fetch_markdown”,
“fetch_txt”,
“fetch_json”
]
}
}
}

It always can run in cline or roo code.

In cursor 0.45, it also can run , but with the node window opening.
