If that download fails after some addresses have already come in, Claude Code now keeps those addresses. It used to keep nothing. The usage report it sends also now gives the number of addresses kept instead of 0.\n\n**Why**\n\nOfficial servers can still be recognised when the registry download only half works.\n\n- Area: MCP\n- Tier: You'll notice\n- Useful: 1\/5\n- Signal: 0\/5\n- Scope: individual\n- Heads-up: no"}
