Codex

Anysphere

Cursor

A multi-surface engineering agent and an AI-first editor compared on execution and continuity.

Decision guidance

No universal winner.

Codex is a good fit when desktop, terminal, IDE, and cloud delegation must share one workflow. Cursor is a strong fit when the editor is the center of work and background agents hand back into it.

Capability	Codex	Cursor
MCP clientintegration	Supported Codex supports MCP for connecting external tools and systems.	Supported Cursor connects to local and remote MCP servers and provides a curated MCP server directory.
Live web searchintegration	Supported Codex includes a web-search tool for current external information.	Supported Cursor Agent includes web search and URL fetching among its research tools.
Browser controlexecution	Experimental or beta The Codex app includes an in-app browser that Codex can control for localhost web development, with broader control described as evolving.	Supported with conditions Cursor can control a browser through configured integrations such as the curated Playwright MCP server.
Terminal accessexecution	Supported Codex runs software-engineering tasks in command-capable sandbox environments and is also available as a terminal CLI.	Supported Cursor Agent can run commands in the editor terminal, and Cursor also provides a terminal-native CLI agent.
Code executionexecution	Supported Codex executes code and tests inside isolated task environments while working on a repository.	Supported Cursor Agent can edit repository files and execute commands and tests through the terminal tool.

Image inputmedia	Supported Codex can inspect screenshots, technical diagrams, charts, and other visual surfaces during coding work.	Unknown or unverified Feature State did not find enough primary evidence in this review to classify Cursor support for Image input.
Image generationmedia	Supported OpenAI documents image generation and editing as available inside Codex.	Unknown or unverified Feature State did not find enough primary evidence in this review to classify Cursor support for Image generation.
Persistent memorycontinuity	Unknown or unverified Feature State did not find enough primary evidence in this review to classify Codex support for Persistent memory.	Unknown or unverified Feature State did not find enough primary evidence in this review to classify Cursor support for Persistent memory.
Background agentscontinuity	Supported Codex cloud tasks run independently in separate environments and can be delegated in parallel.	Supported Cursor supports remote background agents launched from web or mobile and handed back to the desktop editor.
Third-party connectorsintegration	Supported with conditions Codex connects to external systems through configured MCP servers and other available tools.	Supported Cursor’s MCP directory provides connectors for services including GitHub, Linear, Notion, Figma, and databases.
Desktop applicationplatform	Selected platforms OpenAI offers a Codex desktop app with an integrated workspace and browser.	Supported Cursor is an installed desktop code editor for macOS, Windows, and Linux.
IDE integrationplatform	Supported Codex operates across app, CLI, and IDE extension surfaces, with shared agent workflows.	Supported Cursor is itself an AI-first IDE and exposes its agent tools inside the editor.

Unknown means this research pass did not find enough primary evidence to classify the capability. It does not mean the product lacks the feature.
