Permission rules decide whether Claude may use a tool without asking you. `mcpServerPolicy` entries now feed into two kinds of rule:\n\n- Always-allow rules: entries are merged with the existing always-allow rules. Before, these came only from the always-allow rules themselves.\n\n- Ask rules: a filtered set of entries now decides when Claude asks you first.\n\n**Why**\n\nWhether Claude asks before using some MCP tools may change.\n\n- Area: MCP\n- Names: `mcpServerPolicy`\n- Tier: You'll notice\n- Useful: 3\/5\n- Signal: 3\/5\n- Scope: org\n- Heads-up: yes"}
