The message used to speak only of claude.ai connectors.\n\nA new switch, `tengu_bubbly_meteor`, is also present. It is controlled from Anthropic's servers and falls back to on when the server sends nothing, combined with a second condition.\n\n**Why**\n\nThe wording change makes the log message apply to MCP servers in general rather than to claude.ai connectors only.\n\n- Flag `tengu_bubbly_meteor`: Not enough to say (read for one account on one subscription tier against v2.1.286; this account: no value returned, anonymous baseline: no value returned, compiled default: on) These values were read against a different version of Claude Code, so treat them as the nearest reading available instead of one taken on this release.\n- Area: MCP\n- Tier: Under the hood\n- Useful: 1\/5\n- Signal: 2\/5"}
