Cursor

Coding agents · Cursor AI, Cursor IDE

A code editor app from Anysphere, built on VS Code, with a built-in AI agent: you work in the editor, the agent sits next to you, and you pick a model from different vendors or use its own Composer model. The agent does what Claude Code and Codex do: reads the project, edits files, runs commands; there is also a terminal version and cloud agents. It reads project rules from AGENTS.md and its own rules in .cursor/rules, and connects outside systems through MCP.
