STDIO mode has logging info in STDIO #33
Description
I've started a Laravel MCP server in STDIO mode and connected it to Cursor.
The cursor logs (/Users/ruurtjan/Library/Application Support/Cursor/logs/20250709T112740/window1/exthost/anysphere.cursor-retrieval/MCP Logs.log) show:
2025-07-10 10:49:36.646 [error] user-wirewiki: Client error for command Unexpected token 'S', "Starting MCP server" is not valid JSON
2025-07-10 10:49:36.646 [error] user-wirewiki: Client error for command No number after minus sign in JSON at position 3 (line 1 column 4)
2025-07-10 10:49:36.646 [error] user-wirewiki: Client error for command No number after minus sign in JSON at position 3 (line 1 column 4)
2025-07-10 10:49:36.646 [error] user-wirewiki: Client error for command No number after minus sign in JSON at position 3 (line 1 column 4)
The offending lines appears to be https://github.com/php-mcp/laravel/blob/main/src/Commands/ServeCommand.php#L83.
It may be that I'm misconfiguring this, in which case an update to the README would likely be helpful.
