> Give your AI a persistent, reusable UI. It builds the app once — you keep it forever.
**open-mcp-apps** is an open engine built on [MCP Apps](https://modelcontextprotocol.io/extensions/apps/overview)
(`ui://`, `io.modelcontextprotocol/ui`) — an extension to the core Model Context Protocol
specification, and [the first official one](https://blog.modelcontextprotocol.io/posts/2026-01-26-mcp-apps/),
live since 26 January 2026. It gives any MCP-Apps-capable host (Claude Desktop, claude.ai, Codex,
ChatGPT, …) three things the extension itself doesn't provide:
1. **An app registry the AI can write to.** Ask for a UI that doesn't exist — the AI reads
the authoring guide, writes a single-file HTML app against a tiny `window.oma` API,
and saves it. From that moment you can open it by name, in this chat and every future one.
2. **Persistent, versioned data — separate from the UI.** Apps bind to generic
*collections* of items backed by SQLite plus an append-only `change_event` ledger. Every
mutation is an idempotent domain command (`command_id`) with optimistic concurrency
(`expected_version`). The AI and the human edit the same store — the widget is just a view.
3. **A shell runtime so AI-written apps actually work.** Serving `ui://`, the engine wraps
the app with the official MCP App bridge, host theming (Claude's design tokens,
light/dark), and the `window.oma` data API. What you write is a view; the protocol,
persistence, idempotency and theming are the engine's problem.
**Which of those hosts *this* engine reaches.** It runs on your machine and binds `127.0.0.1`, so it
serves the hosts on that same machine: Claude Desktop, Claude Code, Codex, plus its own browser
viewer. A browser host cannot reach a loopback server on your laptop, so **claude.ai and ChatGPT web
need a remote deployment** — today that means the hosted [openmcp.app](https://openmcp.app), which
runs this same engine for you. Running that remote shape *yourself* is on the roadmap and not done.

## Install
open-mcp-apps runs as a local MCP server. First get it **connected** to your host (below); then
**onboarding happens inside the host, separately** — that's where the AI builds your first app.
### From npm — nothing to clone
If you are comfortable editing your host's config file, point it at the published package and
let `npx` fetch the engine. This path needs only Node 22 — no `git`, and no checkout for you to
keep updated. Paste this into your host's MCP server config:
```json
{
"mcpServers": {
"open-mcp-apps": {
"command": "npx",
"args": ["-y", "@2nd1st/open-mcp-apps"]
}
}
}
```
The one thing the installer below adds is registering the server into every host it finds. Either
way the server seeds the system apps (settings, dashboard, App Store) when it starts, and your data
lives in the same fixed per-user store, so you can move between an `npx` server and a cloned one
without migrating anything.
> **A note on npm:** this project publishes under the **scoped** name
> [`@2nd1st/open-mcp-apps`](https://www.npmjs.com/package/@2nd1st/open-mcp-apps). The *unscoped*
> `open-mcp-apps` on the registry is **not this project** — that name is held by an unrelated
> package. Check for the `@2nd1st/` prefix; the scope is the only thing telling the two apart.
### With the installer — one command
Installing needs a shell, so the chat apps (Claude Desktop, Codex) can't install themselves — use
one of these instead:
```bash
curl -fsSL https://raw.githubusercontent.com/2nd1st/open-mcp-apps/main/install.sh | sh
```
It opens a short picker to choose which hosts to register into — **Claude Desktop, Claude Code,
Codex** — plus your permission preference. Skip it with `-s -- --yes`, or target one host with
`-s -- --host codex`.
**Where it puts the clone**, before you pipe anything into a shell: `~/open-mcp-apps`. Set `OMA_DIR`
to put it somewhere else — `curl -fsSL <url> | OMA_DIR=~/src/oma sh`. Re-running the one-liner
updates that same clone in place instead of making a second one. Your apps and data are *not* in it
(they live in the per-user store under [Configuration](#configuration)), so the folder is safe to
move or delete — and `node uninstall.mjs` does not delete it for you.
**With a coding agent** (Claude Code, Codex CLI — they have a shell), paste:
> Read https://raw.githubusercontent.com/2nd1st/open-mcp-apps/main/install.md and follow it.
Either way, `install.mjs` registers the server into each host you pick, idempotently — it never
clobbers your other servers, pins a stable `node` launcher (native SQLite ABI), reports what
changed, and cleans up a pre-rename entry if one lingers. Your data lives in a **fixed per-user
store** (not inside the clone), so every host shares the same apps and data.
### From a clone — for development
```bash
git clone https://github.com/2nd1st/open-mcp-apps && cd open-mcp-apps
npm install
node install.mjs # same picker as the one-liner above
```
To wire a clone into a host by hand instead, point it at the checkout — this is the shape
`install.mjs` writes:
```json
{
"mcpServers": {
"open-mcp-apps": {
"command": "node",
"args": ["/absolute/path/to/open-mcp-apps/src/server.mjs"]
}
}
}
```
### Hosted
[openmcp.app](https://openmcp.app) runs the engine for you. The engine in this repository binds
`127.0.0.1` by design, so a self-hosted remote deployment is not a supported shape yet — see
[Status and roadmap](#status-and-roadmap).
### Uninstall
`node uninstall.mjs` unregisters the server from every host it finds — but **keeps your data**:
the shared store stays put, so re-installing later restores every app and all data. It also leaves
the installer's clone (`~/open-mcp-apps`, or wherever `OMA_DIR` pointed) on disk — nothing here ever
deletes that folder, so remove it yourself when you want the checkout gone.
```bash
node uninstall.mjs # unregister from all detected hosts — keeps your data
node uninstall.mjs --purge # also delete the shared store (apps + data), irreversible
node uninstall.mjs --check # read-only: show what's registered and what would change
```
## Requirements
- **Node 22 or newer**, on macOS, Windows or Linux.
- **`git`** — only on the installer path. The `npx` path above needs neither `git` nor a checkout.
The installer checks for both and stops with a message rather than half-installing if either is
missing.
- **A host that renders `ui://`** if you want widgets *in the conversation*. Terminal hosts (Claude
Code in a terminal, codex CLI) drive the same data by design and put the UI on a browser screen
beside the terminal instead — one that can follow along, showing whatever the AI just opened. The
per-host detail is in [Host support](#host-support).
- **After installing or updating, fully quit and reopen the host** (Cmd-Q, not just closing the
window) — it keeps its old server process on the old data until fully quit.
## Configuration
Every setting is an environment variable, set in the `env` block of your host's MCP server entry:
```json
{
"mcpServers": {
"open-mcp-apps": {
"command": "npx",
"args": ["-y", "@2nd1st/open-mcp-apps"],
"env": {
"OMA_VIEWER": "1",
"PORT": "8787"
}
}
}
}
```
| Variable | Default | What it does |
|---|---|---|
| `OMA_VIEWER` | `1` | The browser viewer on loopback. `0` doesn't start it at all. |
| `PORT` | `8787` | Where the viewer listens. |
| `OMA_DB` | per-user store | Path to the SQLite store. Set it to isolate a store. |
| `OMA_APP_STORE_DIRS` | — | Extra App Store sources: folders laid out like the store package's `apps/` (one folder per app), separated by `:` (`;` on Windows). Searched before the installed [`@openmcp-app/oma-store`](https://github.com/openmcp-app/oma-store) package; the first source with a name wins. |
| `OMA_FUNCTIONS` | on | `0` turns app functions (`call_function`) off. A function body runs on this machine and can make network requests. |
**An app's own tool.** Every app opens through `open_app`. To give one app its own `open_<name>`
tool as well, pin it: **Settings → Installed → the app → Own tool**. The tool list changes only
when you pin, unpin or delete a pinned app, and Claude.ai and ChatGPT show the new tool after you
refresh the connector's tool list.
**Where your data lives.** The whole store is one SQLite file, `open-mcp-apps.db`, in
`~/Library/Application Support/open-mcp-apps/` (macOS), `%APPDATA%\open-mcp-apps\` (Windows), or
`$XDG_DATA_HOME` else `~/.local/share/open-mcp-apps/` (Linux). It is outside any clone, which is
why every host shares the same apps and data.
**First-run permissions.** The first few tool calls each show an approval dialog — pick
**"Always allow"**. The tool set is small and stable on purpose: read-only tools generally
skip approval, and the single `open_app` tool covers opening *every* app (including ones the AI
creates later) behind that one grant, so nothing new asks again. An `OMA_DYNAMIC_TOOLS=1` left in
an older entry does nothing; `node install.mjs --check` reports it as `stale`, and re-running the
installer removes that one key.
You can also batch approvals in **Settings → Connectors → open-mcp-apps → Tool permissions**.
## Usage
**Start in your host.** Restart it after installing. New here? The engine ships one MCP prompt,
`get_started`. A host that surfaces prompts lists it as **Get started with open-mcp-apps**; hosts
that render prompts as slash commands spell it `/mcp__open-mcp-apps__get_started`. Picking it hands
the AI the whole opening move. Not every host surfaces prompts — where yours doesn't, nothing is
lost, because the prompt is just a sentence you can say yourself: **"I just installed open-mcp-apps
— show me how to use it with a couple of examples, and suggest a few apps that fit how I work."**
Either way it looks at what you already have and what the App Store already offers, asks you a
couple of questions, and sets up a first app tailored to you. This step is separate from install and lives in the host. Or just ask directly:
- *"make me a board for what I'm juggling right now"* → the AI writes it, seeds it, and opens it (persistent)
- *"make me a habit tracker"* → watch it read the guide, write the app, save it, open it
- close the app, reopen, ask again → everything is still there
### The loop
```
"make me a kanban"
│
▼
list_apps ── exists? ──► open_app {app: "kanban"} (reuse, instant)
│ no
▼
get_app_guide ──► AI writes HTML ──► save_app
│
▼
open_app {app: "kanban"} → rendered inline, themed, persistent — reusable in every future chat
```
Apps accumulate. Each one is single-purpose and independent — a board, a tracker, a
splitter — minted for the task in front of you and kept for the next time you need it.
### What it looks like
Apps render inline, in the chat you were already having. Ask for one and the AI writes it:
Come back in another chat — or another host — and it's still there, with your data in it:
The App Store ships ready-made apps, with working previews and one-click install. They live in
their own package, [`@openmcp-app/oma-store`](https://github.com/openmcp-app/oma-store), which the
engine installs as a dependency — new store apps are contributed there:
| | |
|---|---|
|  |  |
|  |  |
Every app above is a single HTML file bound to plain data collections — written with the same
`window.oma` API and authoring guide your AI will use for the apps it builds you.
Multiple widgets in one conversation work fine (habit-streaks + meal-planner side by side).
### The browser viewer, and the port it binds
Every install runs a small local web server on **<http://127.0.0.1:8787>**. It is how you *see*
your apps outside a chat window — one page per app, the same data your AI is reading — and in a
terminal host it is the only way to see them at all, so the AI hands you the link when it builds
or opens something.
It starts on its own; `OMA_VIEWER` and `PORT` above change that. If the port is already taken by
another open-mcp-apps process, that one is already serving the same data and this one just shares
its address; if it is taken by something else, you get no viewer and no links rather than a link
into a stranger's server.
**There is no password on it, and that is deliberate.** The listener is hard-wired to `127.0.0.1`,
so there is no setting that makes it answer from another machine. Any program on your computer that
could reach the port can already open the SQLite file directly — a password would be a lock beside
an open wall. The one way this reaches the internet is a tunnel you start yourself, which is its own
deliberate decision; **while a tunnel is up, treat its URL as a secret**, because it is currently the
only thing standing between the internet and your data.
## Host support
Live-tested 2026-07-22 (ChatGPT web 2026-07-28), except cells that carry their own date. A date
says when a cell was true, not that it was checked again since.
| Host | Renders widgets | Human clicks widget | AI operates data | Same store |
|---|---|---|---|---|
| **Claude Desktop** (local stdio) | ✅ — re-checked 2026-08-16 on 1.30096.5: the universal `open_app` renders in chat without the `OMA_DYNAMIC_TOOLS` workaround that shipped for 1.24012.9 (see KNOWN-ISSUES) | ✅ full loop incl. `sendMessage` reply | ✅ | ✅ |
| **Browser viewer** (`/view/<name>`) | ✅ | ✅ (no chat attached — `sendMessage` degrades to a notice) | via CLI AI | ✅ |
| **Codex desktop** (ChatGPT app, `enable_mcp_apps` flag) — tested against a **local** engine; remote not established | ✅ experimental | ◐ updates/toggles from widget clicks work; adds were blocked host-side. The umbrella request [openai/codex#28912](https://github.com/openai/codex/issues/28912) (an `enhancement`: "make MCP apps work end-to-end in the Codex GUI") closed as completed on 2026-08-05 — but [#30092](https://github.com/openai/codex/issues/30092), the `bug` matching this exact failure and reproduced there by a third party, was still open on 2026-08-16. Not re-tested here either way, so the cell stays ◐. See KNOWN-ISSUES | ✅ | ✅ |
| **Claude Code** — in a terminal (`claude mcp`) | — in the chat, by design (text fallback) — but see **[a screen beside the terminal](#a-screen-beside-the-terminal)** | — in the chat | ✅ | ✅ |
| **Claude Code** — the Code surface inside the Claude app | ✅ live-tested 2026-08-16: an app opened with the universal `open_app` renders inline, the same shape the chat surface gives | not measured on this surface | ✅ | ✅ |
| **codex CLI / IDE** | — in the chat, by design (text fallback) — but see **[a screen beside the terminal](#a-screen-beside-the-terminal)** | — in the chat | ✅ | ✅ |
| **ChatGPT web** (Work mode) | ✅ live-tested 2026-07-28 (remote HTTPS) — renders at full height, no clamping; a widget loses its data after a page refresh (mitigation shipped, awaiting live re-test here — see KNOWN-ISSUES) | ✅ a widget button added a row and it stuck | ✅ | ✅ |
Everything rides the MCP Apps bridge, so host fixes upstream (e.g. #28912) benefit this
project with zero changes.
**On Claude Code specifically:** it is one product with two surfaces, and only one of them can
draw — which is why it takes two rows. In a terminal there is no inline widget surface at all: that
is architecture rather than a gap, and it is exactly what [a screen beside the
terminal](#a-screen-beside-the-terminal) is for. The Code surface inside the Claude app has a UI and
renders inline; the 2026-08-16 reading there came through the universal `open_app`.
**On Codex specifically:** plugins are registered on the web side, so a locally-installed engine
is reached as an **MCP server**, not as a plugin — which is the right path for a self-hosted
install anyway. Widget rendering in the ChatGPT desktop app also appears to depend on how you are
signed in (we have seen it work under an account sign-in; not yet established under an API key).
### A screen beside the terminal
Those two `—` cells say the **chat** shows text. They do not say there is no UI. The
engine remembers which app was opened last and pushes that pointer to the viewer on the `/events`
frame, and an app can place a region — `oma.embed("@live", {into})` — that mounts whatever the AI
opened last and swaps itself when the AI opens another. The App Store ships one: install **`live`**,
open `http://127.0.0.1:8787/view/live` in a window you then leave alone, and the terminal keeps the
conversation while that screen shows the app. The AI opens or writes from the CLI, the screen
follows, and you can click, edit and type into it there. Headless CLI use is what it was built for.
**The cheapest form of "that screen" is a browser pane in the same tiled workspace** — one column
over from the agent, in the window you are already working in. Same machine, no tunnel, no second
device; most modern terminal setups can put a browser next to a shell, and that is all this needs.
A second monitor is the same idea with more desk, and a screen on another device is the same idea
again with the caveat below.
The costs are real and worth stating plainly. There is still **no widget in the transcript**.
`sendMessage` degrades to a notice on a standalone page, exactly as in the **Browser viewer** row —
clicks change data, they do not talk back to the chat. The viewer has to be running (`OMA_VIEWER`,
on by default) with a browser pointed at it; this is not zero-config. And the listener is bound to
`127.0.0.1`, so "a spare tablet on the wall" means *this machine's* screen unless you put up the
tunnel described above and accept what that section says about it. Inside a chat host the same
region deliberately draws a placeholder instead of following anything.
*Described from the code as built, not measured on a host — the live-test dates above cover the
table, not this section.*
## Writing an app yourself
The AI is the usual author, but it isn't the only one — its context window shouldn't be the ceiling
on what an app can be. Build one in your own editor, with your own bundler, and install it:
```bash
node install-app.mjs ./my-app.html # yours, full trust — same as an AI-authored app
node install-app.mjs ./my-app.html --sandboxed # untrusted: runs behind the runner, no capabilities
node install-app.mjs --list # what's installed, and under whose provenance
# a build pipeline's output: a readable template + its bundle, plus the declaration as its own file
node install-app.mjs ./ui.html --name my-app --manifest ./manifest.json \
--asset ./dist/app.js --asset ./dist/app.css --update
```
Two shapes are accepted. **One self-contained HTML document** — no size cap (keep it lean: data
lives in the collection, source is read in windows) — the engine injects a minimal base style, the
host's design tokens and `window.oma`. Or **a template plus a bundle**: the HTML is a readable mount
point that references its own build output (`<script type="module" src="oma-asset:app.js">`,
`<link rel="stylesheet" href="oma-asset:app.css">`), `--asset` pushes those files into the app's
file plane, and the engine inlines them the moment the document leaves the store — a host iframe
cannot reach this machine.
The trade: the AI can no longer iterate on it — your files are the source of truth, you rebuild
and re-install. It can still read a single-document app's source; for a template + bundle app it
reads the template and the bundle stays yours (`edit_app` and the AI's `save_app` refuse with
`built_outside`; re-running the command above is the edit). Either way the app shares your data
like any other. Provenance is not overwritable in either direction, so an app installed
`--sandboxed` stays sandboxed until you delete it. What a widget may connect to is the app's own
declaration (`manifest.csp`, relayed to the host per the MCP Apps spec — nothing by default), and
an app's *functions* run engine-side and may `fetch` — see RUNTIME.md §5.1 and §6.1, and
the two type files for what an app sees — `@2nd1st/open-mcp-apps/types/window-oma` (the
`window.oma` API) and `@2nd1st/open-mcp-apps/types/oma-function` (the `args`/`api` a function body
gets) — both resolve through the package `exports`.
**[`RUNTIME.md`](RUNTIME.md) is the contract** — the `window.oma` API in both modes, what a
sandboxed app can still do, and the traps that only bite authors who aren't the AI. It carries a
version, and `test/runtime-contract.mjs` pins it to the two runtimes' real surfaces, so it can't
drift from them silently.
## Security model
Trust is tiered by where an app came from — [`SECURITY.md`](SECURITY.md) has the detail.
- **Local, full trust**: your apps, AI-built apps, the system apps, and everything installed from the
App Store — including `OMA_APP_STORE_DIRS` folders. They run in direct mode with the real `window.oma`.
- **Sandboxed**: apps installed with `--sandboxed`, and apps opened through a share, run behind the
runner — a sandboxed `srcdoc` iframe whose bridge reaches only the app's own collection unless granted more.
- **App functions run on your machine and can make network requests.** On by default;
`OMA_FUNCTIONS=0` turns them off.
- **The AI can operate the open app** (`screen_read` / `screen_act`) the way you could, but it
cannot confirm a deletion for you.
- Reserved `security:*` / `policy:*` config keys are out of reach of generic data writes; the HTTP
transport binds to loopback.
## Design positions (why it's built this way)
- **UI and data persist separately, both versioned.** Apps are views; collections are
truth; the ledger is history. Swap either without losing the other.
- **The AI talks domain commands, never SQL, never raw state.** That's what makes human+AI
concurrent editing safe (idempotency + optimistic concurrency at the command layer).
- **Extension-first.** Everything rides the MCP Apps bridge — no host-private APIs.
One codebase should serve every host that renders `ui://`.
- **Single-purpose, not composite.** Each app owns one scenario and its own collection; the
engine mints a new one rather than cramming features into an old one. System apps (settings,
dashboard) are the deliberate exception — engine-owned, privileged, allowed to see across
collections.
## Troubleshooting
| Symptom | What it is |
|---|---|
| Updated, but the host still shows the old behaviour | The host keeps its old server process on the old data until **fully quit** (Cmd-Q, not just closing the window). |
| Approval dialogs came back after a Claude Desktop auto-update | A Desktop auto-update occasionally resets these decisions (upstream [#56954](https://github.com/anthropics/claude-code/issues/56954), closed 2026-06-23 as *not planned*) — no fix is coming from that issue, so just re-allow. |
| One approval prompt per app | Each app you pinned (**Settings → Installed → the app → Own tool**) has its own `open_<name>` tool, and a host asks once per tool. Unpin the ones you don't need. An `OMA_DYNAMIC_TOOLS=1` left in your host entry from 2026-07-28–2026-08-16 does nothing any more; `node install.mjs --check` calls it `stale` and re-running the installer removes that one key. See [Configuration](#configuration). |
| No viewer link, or the viewer is somebody else's | The port is taken by a non-open-mcp-apps process. Set `PORT` to something free. |
| A widget loses its data after a page refresh (ChatGPT web) | Known, mitigation shipped, live re-test pending — [`KNOWN-ISSUES.md`](KNOWN-ISSUES.md). |
| Widget clicks can update but not add (Codex desktop) | Blocked host-side. The umbrella request [openai/codex#28912](https://github.com/openai/codex/issues/28912) closed as completed on 2026-08-05, but that one is an `enhancement`, not this defect: the matching `bug`, [#30092](https://github.com/openai/codex/issues/30092), was still open on 2026-08-16. Update Codex and try, but expect it to still bite. |
| You want to start completely clean | Fully quit your host(s), delete `open-mcp-apps.db` (plus its `-wal`/`-shm` siblings) from the store directory under [Configuration](#configuration). All apps and data gone, irreversibly, while staying installed. |
## Development
| | |
|---|---|
| `src/server.mjs` | stdio MCP server; single `open_app` path (plus an `open_<name>` tool for each app the user pins) |
| `src/http.mjs` | `/mcp` (stateless Streamable HTTP) + `/view/<name>` browser viewer, bound to `127.0.0.1` |
| `src/store.mjs` | SQLite: items + app registry + `change_event` ledger (idempotent, OCC) |
| `src/shell-runtime.js` | browser runtime injected into every app (`window.oma`) |
| `src/shell.mjs` | wraps stored HTML with runtime + design-token fallbacks at serve time |
| `src/guide.mjs` | the authoring contract the AI reads before generating an app |
| `install-app.mjs` | install an app you wrote yourself, from a file — the one door into the registry that doesn't go through the AI |
| `components/` | the 3 system apps, installed on seed (settings, dashboard, app-store). The App Store's apps are the [`@openmcp-app/oma-store`](https://github.com/openmcp-app/oma-store) dependency — not auto-installed; browse the app-store app for live previews with sample data and one-click install |
```bash
npm test # every suite below, plus the static invariants and budget checks
node test/server-smoke.mjs # 461 assertions over real stdio — incl. runtime app creation
node test/http-smoke.mjs # 85 assertions over the HTTP transport (incl. SSE /events, viewer)
node test/provenance.mjs # 39 assertions that an app's author — its trust tier — is not overwritable
node test/seed-smoke.mjs # 30 assertions on the seed pipeline
node test/files-smoke.mjs # 24 assertions on the per-app file store (dedup, integrity, GC races)

## Status and roadmap
Early v0 — proven end-to-end on Claude Desktop; cross-vendor render + shared store proven
on Codex desktop and the browser viewer.
Where it stands:
- [x] engine: registry + shell + generic data commands + ledger
- [x] system apps installed (settings, dashboard, app-store); App Store apps (the `@openmcp-app/oma-store` package) with live previews, one-click install
- [x] AI app creation loop (guide → save → open)
- [x] in-context onboarding (the `get_started` prompt → the AI builds a first app for how you work)
- [x] security foundation: trust tiers + sandboxed runner + reserved config keys
- [x] multi-host discovery installer (Claude Desktop · Claude Code · Codex) + shared per-user store
- [x] `npx` one-command install (`@2nd1st/open-mcp-apps` on npm)
