Key Features

Unified Agent Workspace: A single environment for orchestrating and managing autonomous agents that collaborate to build, modify, and validate software projects, enabling multi-step agent workflows.
AI Code Editor: Intelligent code generation and autocomplete embedded in the editor to create complex components, refactor code, and assist with architecture decisions and implementation.
Cursor Rules: Customizable guidance rules that enforce design systems, coding patterns, and project-specific best practices so generated code remains consistent and aligned with developer intent.
Plugin Ecosystem & Templates: A plugin specification, official plugins, and plugin-template repository that let teams extend the editor, add integrations, and connect external services or tools.
MCP (Model Context Protocol) Support: mcp-servers and related tooling to connect model-driven agents and developer services securely, enabling richer context sharing between tools and agents.
Agent Tracing & Auditing: agent-trace standard for recording and tracing AI-generated code and agent decisions, supporting auditability and reproducibility of agent outputs.
