What's Wrong?

Adding an MCP server for the project scope:

claude mcp add --scope project --transport stdio xxxxx -- "npx -y @modelcontextprotocol/server-postgres postgresql://postgres:postgres@localhost:5667/xxxxx"

After this, claude has created a local .mcp.json file:

{
  "mcpServers": {
    "xxxxx": {
      "type": "stdio",
      "command": "npx",
      "args": [
        "-y",
        "@modelcontextprotocol/server-postgres",
        "postgresql://postgres:postgres@localhost:5667/xxxxxx"
      ]
    }
  }
}%

However, after this, claude still dont find any mcp server configured here:

claude mcp list

No MCP servers configured. Use claude mcp add to add a server.

What Should Happen?

claude code would list the mcp server.
