A tool result can carry a `_meta` field, which holds extra details. When that field is too large, Claude Code leaves it off and shows a warning.\n\nThe warning now says the marker is kept together with a second marker beside it. Before, it said only that the marker, if set, is kept.\n\n**Why**\n\nThis is a small change to how MCP results are handled. If you read these warnings or build an MCP server, expect the new wording and the extra kept marker.\n\n- Area: MCP\n- Tier: You'll notice\n- Useful: 1\/5\n- Signal: 1\/5\n- Scope: individual\n- Heads-up: no"}
