After you add one, Claude Code shows a short confirmation. When Claude Code routes MCP tools through the REPL (an environment where Claude runs code that calls tools), that message now says the server's tools are callable inside the REPL environment. Before, it always said the tools should now be available.\n\n**Why**\n\nIn REPL mode the message now tells you how the new tools are actually reached.\n\n- Area: REPL Mode\n- Tier: You'll notice\n- Useful: 1\/5\n- Signal: 2\/5\n- Scope: individual\n- Heads-up: no"}
