Quick Start: Cursor¶

Create or edit .cursor/mcp.json:

{
  "mcpServers": {
    "mcp-v8": {
      "command": "mcp-v8",
      "args": ["--directory-path", "/tmp/mcp-v8-heaps"]
    }
  }
}

For stateless mode:

{
  "mcpServers": {
    "mcp-v8": {
      "command": "mcp-v8",
      "args": ["--stateless"]
    }
  }
}

Restart Cursor, then ask it to run:

console.log(1 + 2)

If your Cursor setup uses a remote HTTP MCP endpoint instead of a local stdio process, the config can look like this:

{
  "mcpServers": {
    "mcp-v8": {
      "url": "http://localhost:3000/mcp"
    }
  }
}
