# OpenAI's Codex CLI Now Imports Your Cursor and Claude Code Setup in One Command

> The v0.145.0 /import command migrates settings, MCP servers, plugins, sessions, commands, and project memories out of rival coding agents — quietly deleting the switching cost that kept teams put.

## Key takeaways

- On 21 July 2026, OpenAI shipped Codex CLI v0.145.0, and the headline line in the release notes is a migration tool: `/import` now pulls your settings, MCP servers, plugins, sessions, commands, and project-scoped memories out of Cursor and Claude Code and into Codex.
- That single feature attacks the one thing that actually kept teams on a coding agent — not capability, but the cost of re-wiring your config, your MCP tool connections, and your accumulated project context somewhere new.
- The strategic read for founders: coding-agent lock-in is now a weakening moat. When the setup is portable in one command, you get to choose your agent on capability, price, and trust — and re-choose it next quarter without a migration project.
- The same release stabilizes multi-agent V2 (configurable sub-agent models and concurrency) and adds experimental Amazon Bedrock login with GPT-5.6 Sol as the default — but `/import` is the one that changes the market, because it makes leaving cheap.

## At a glance

| What used to lock you in | Before /import | After Codex v0.145.0 |
| --- | --- | --- |
| Editor/agent settings | Re-created by hand in the new tool | Imported automatically |
| MCP server connections | Re-registered one by one | Migrated in the import |
| Custom commands & plugins | Rebuilt from memory or docs | Carried across |
| Project-scoped memory/context | Lost — you start cold | Brought over per project |
| Realistic switching cost | An afternoon (or a reason not to bother) | One command |
| What you now choose on | Whatever you already set up | Capability, price, trust — re-evaluated freely |

## By the numbers

- **/import** — the one command that migrates settings, MCP servers, plugins, sessions, commands, and project memories from Cursor and Claude Code into Codex
- **v0.145.0** — the 21 July 2026 stable release that shipped it
- **One command** — the new switching cost between coding agents — down from an afternoon of re-wiring

**If you read one line:** OpenAI's Codex CLI v0.145.0 (21 July 2026) added an `/import` command that migrates your settings, [MCP servers](/topics/mcp), plugins, sessions, commands, and project memories out of [Cursor](/stack/cursor) and Claude Code in one step. The news isn't the feature — it's what the feature is *for*: it deletes the switching cost that was the only real thing keeping teams on any one [coding agent](/topics/coding-agents).
For two years the coding-agent market has been a leapfrog race on capability — a new model, a longer context window, a smarter sub-agent loop every few weeks. Founders learned to ignore most of it, because the thing that actually decided which agent you used wasn't the benchmark. It was the afternoon you'd already spent wiring up your MCP servers, rebuilding your custom commands, and letting the tool accumulate context about your codebase. That setup was the moat. Nobody re-tools every time a rival ships a point release.
Codex v0.145.0 goes straight at that moat. Per [OpenAI's official release notes](https://github.com/openai/codex/releases), the update "expanded `/import` to migrate Cursor and Claude Code settings, MCP servers, plugins, sessions, commands, and project-scoped memories" into Codex. In other words: the accumulated environment that made leaving painful now travels with you in a single command.
Why a migration command out-matters a new model
Switching cost, not raw capability, is what keeps a team on a given agent. Models are fungible on a timescale of weeks; your *configuration* is not, because rebuilding it is manual, boring, and easy to keep postponing. A one-command import collapses that. The setup you'd have re-created by hand — the exact thing you'd cite as the reason not to bother trying a competitor — is now portable.
> The moat around a coding agent was never the model. It was the config you'd already built. `/import` is a bulldozer aimed at that config.

Notice the direction, too. OpenAI is importing *from* Cursor and Claude Code — it's advertising that leaving those tools is easy. That's a competitor confident it wins the head-to-head once friction is removed, which tells you how the vendors themselves now rate lock-in as a defense: not much. And the logic cuts both ways. The same portability that pulls you into Codex is what lets you leave Codex later. Portability, not any one tool, is the feature.
The rest of v0.145.0, briefly
The release did more than ship a migration path. It stabilized the opt-in **[multi-agent](/topics/agent-frameworks) V2** experience — configurable sub-agent models, reasoning levels, and concurrency — so you can point cheaper models at cheaper sub-tasks. It added **experimental Amazon Bedrock login** with custom endpoints and GPT-5.6 Sol as the default Bedrock model, which matters for teams that must keep inference inside their own AWS account. And it added audio inputs, streaming realtime V3 conversations, and paginated thread history with search and resume. The current stable line is **v0.145.0**; the newest alpha, v0.146.0-alpha.6, is dated 24 July 2026 — so expect this to keep moving fast.
What a founder should actually do
Not switch on reflex. The move is to **re-run the evaluation you've been avoiding.** If you've stayed on a coding agent partly because migrating felt like a project, that reason just expired. Decide on the axes that survive: which agent is genuinely better for your stack, which is cheaper at your token volume, which you trust with your code and your keys. We line those up in [Claude Code vs Codex CLI vs Gemini CLI](/posts/claude-code-vs-codex-cli-vs-gemini-cli.html) and, for the async side, [Devin vs Codex vs Cursor vs Jules](/posts/devin-vs-codex-vs-cursor-vs-jules-background-agents.html).
Then bank the general lesson, because it's bigger than one CLI. Lock-in built on setup friction is a decaying asset across the whole AI stack — the same principle behind keeping your [LLM API choice portable](/posts/how-to-choose-an-llm-api-without-lock-in.html) and your [agent memory exportable](/posts/portable-agent-memory-export-import-no-lock-in.html). When switching is one command, the winning posture isn't loyalty. It's staying ready to move — and letting the vendors compete for you every quarter.

## FAQ

### What does Codex CLI's /import command actually do?

As of v0.145.0 (21 July 2026), `/import` migrates your configuration from a competing coding agent into OpenAI's Codex: settings, MCP servers, plugins, saved sessions, custom commands, and project-scoped memories. The release notes specifically name Cursor and Claude Code as supported sources. The point is that you no longer rebuild your environment by hand when you switch — the accumulated setup that made leaving painful now travels with you.

### Why does a migration command matter more than a new model?

Because switching cost, not raw capability, is what usually keeps a team on a given coding agent. Models leapfrog each other every few weeks; nobody re-tools every time because re-registering MCP servers, rebuilding commands, and re-teaching a tool your project context is real work. A one-command import removes that friction, which means your agent choice becomes a live decision you can revisit instead of a sunk cost you defend.

### Should a founder switch coding agents because of this?

Not automatically — switch only if another agent is genuinely better for your stack, cheaper, or more trustworthy. What changed is that the *cost of switching* dropped to near zero, so you should re-run that evaluation now rather than assuming you're stuck. Treat portability as the feature: the same logic that lets you import into Codex is the logic that lets you leave it later.

### What else shipped in Codex CLI v0.145.0?

Alongside `/import`, the release stabilized the opt-in multi-agent V2 experience with configurable sub-agent models, reasoning levels, and concurrency; added experimental Amazon Bedrock login (custom endpoints/auth, with GPT-5.6 Sol as the default Bedrock model); added audio inputs and streaming realtime V3 conversations; and shipped experimental paginated thread history with search and resume. The stable line is v0.145.0; v0.146.0-alpha.6 was dated 24 July 2026.
