Agent is ready and UI refresh

Source: Cursor Date: 2025-02-19 URL: https://cursor.com/changelog/0-46-x

Summary

Cursor 0.46.x makes Agent mode the default by unifying Chat, Composer, and Agent into a single interface, adds automatic web search without explicit commands, MCP Yolo Mode for automatic tool execution, and .cursorindexingignore for fine-grained indexing control. UI refresh with new default themes. Project rules can now apply globally. 25-tool-call limit extended with a “continue” button.

Implications

Agent-IDE feature race. Unifying Chat, Composer, and Agent into one default interface is the most decisive UX simplification Cursor has made — it removes the cognitive overhead of choosing the right mode and bets that agent-by-default is the right design for all interactions. This mirrors Claude Code’s single-mode design and positions Cursor against the “which mode is this” confusion that plagued earlier multi-mode agent IDEs.

MCP/protocol adoption. MCP Yolo Mode (automatic tool execution without per-call approval) is the MCP equivalent of agent Yolo Mode — it trusts MCP servers to act autonomously. Combined with Agent Yolo Mode (from 0.44), Cursor now has a fully autonomous execution path from agent decision to terminal command to external tool call. The permission surface is minimal by user choice.

Watch: Whether the unified Agent-default interface drives a new user cohort (non-technical users expecting AI-first interaction) and whether MCP Yolo Mode gets enterprise controls to prevent unintended external tool calls in sensitive environments.
