Claude Code loads a list of official MCP server addresses from a registry. It now fills one shared list as it fetches them, instead of taking a finished list back. The log message reporting how many addresses were loaded is unchanged.\n\n**Why**\n\nThis may change how Claude Code handles a registry that returns its results in parts. No visible difference is described.\n\n- Area: MCP\n- Tier: Under the hood\n- Useful: 1\/5\n- Signal: 0\/5\n- Scope: individual\n- Heads-up: no"}
