For immediate release · September 25, 2026
Google Antigravity, connected to Smol in one click.
Smol 1.0.35 adds Antigravity to its AI access panel alongside Claude Code and Codex. One click hands your agent compression, format conversion, AI upscaling, metadata removal, and Neural compression over MCP — running locally, on your Mac, on files that never leave it.

Smol implements the open Model Context Protocol, so the connection mechanism is the same one every MCP client uses. The panel exists to remove the hand-editing, not to lock the protocol down.
Smol 1.0.35 adds one-click support for Google Antigravity, joining Claude Code and Codex in Smol’s AI access panel. The update was built in response to customer feedback, and it gives an Antigravity agent the full Smol media toolkit: compression, format conversion, AI upscaling, metadata removal, and Neural compression, all driven precisely through the Model Context Protocol.
The friction it removes is specific. Adding an MCP server by hand means finding the right settings file, writing a JSON block into it without breaking the entries already there, and getting the command and arguments exactly right. It is the kind of task that works on the second attempt. Smol now does it for you: click Connect, and Smol adds itself to Antigravity’s own MCP settings.
What it does not do is clobber your setup. Every other MCP server you have configured is preserved, and if Smol cannot safely read the existing settings file, it declines to write rather than replacing it with a fresh one. There is nothing to copy, paste, or edit by hand, and nothing quietly lost if your config is unusual.
“This one came straight from customer feedback. The work wasn’t the protocol — it was making the connection boring. One click, your other servers untouched, and nothing to hand-edit. Then the interesting part is the tools.”
As with every Smol workflow, files are processed locally and never leave the user’s Mac. The release also refreshes the design of the AI access panel, and is rolling out now through Smol’s built-in updater for both Apple Silicon and Intel Macs.
The part that actually differs
It is a local MCP server, not a hosted one.
A cloud MCP media tool is, by construction, a thin client in front of somebody else’s API. Your file goes up, a job runs on hardware you do not control, a result comes back. That is a reasonable design for plenty of things. It is a disqualifying one for client photography, unreleased product renders, medical scans, legal exhibits, and anything covered by an NDA.
Smol’s MCP server runs inside the Smol app on your Mac. Antigravity connects to that. Files are read from disk, encoded by encoders that shipped inside the app, and written back to disk, and no part of that round trip involves a network. There is no upload queue, no processing region, no retention window, and no per-file quota, because there is no service on the other end.
It also means the agent is not rate-limited by anyone. A folder of several thousand images is a long job, not an expensive one.
What Connect does
Smol writes itself into Antigravity’s settings.
The whole point of the button is that you never see the file it edits. These are the rules it follows while editing it.
- It edits Antigravity’s own settings
- Smol adds its MCP server entry directly to the MCP settings file Antigravity already reads. Nothing to copy, nothing to paste, no JSON to hand-edit.
- Your other servers survive
- Every MCP server you already had configured is kept. Smol is added alongside them, not in place of them.
- It refuses rather than guesses
- If Smol cannot safely read the existing settings file, it will not overwrite it. A config it cannot parse is left alone instead of being replaced with a clean one.
- The state is visible
- The panel shows a live status for each client, so whether Antigravity is connected is something you can see rather than something you go and verify in a text editor.
The tool surface
What an Antigravity agent can actually ask for.
Not one generic compress action. Each operation takes explicit parameters, so the agent states a quality target, a format, and a batch policy rather than hoping a default is close enough. Everything below is the full list — Smol does not do formats that are missing from it.
| Operation | Output formats | Control the agent sets |
|---|---|---|
| Compress images | jpg · png · webp · avif · heic · gif | Quality 0–100, resize up to 32,768 px, fit / fill / width / height |
| Compress PDFs | tiny · small · medium · large · original | Five presets, chosen explicitly rather than one "reduce size" button |
| Compress video | mp4 · mov · webm · mkv | CRF 0–63, nine encoder presets from ultrafast to veryslow |
| Compress audio | aac · m4a · mp3 · wav · flac · ogg · opus | 16–512 kbps, 8–192 kHz |
| Convert images | jpg · png · webp · avif · heic · tiff · bmp · gif · pdf | Same encoder settings as compression, applied on the way out |
| Convert PDFs to images | png · jpg | Page rasterization without a browser upload |
| Convert documents | Word → pdf, docx, odt, rtf, txt, html · Sheets → pdf, xlsx, ods, csv, html · Slides → pdf, pptx, odp | Office and OpenDocument round-trips, locally |
| Convert video and audio | Video → mp4, mov, webm, mkv · Audio → m4a, mp3, wav, flac, ogg | Note the asymmetry: AAC and Opus are compression outputs, not conversion targets |
| Convert tables and fonts | csv · tsv · json · ndjson · html · md · xlsx · numbers — and ttf · otf · woff · woff2 | Data and webfont chores an agent would otherwise shell out for |
| Upscale images | 2×, 3× or 4× → png, jpg, webp | A local machine-learning model, no per-image credit |
| Neural compress | avif · webp · jpg · png | A target size of 4–4096 KB — "land this under 500 KB" as an actual parameter |
| Strip metadata | EXIF, GPS, IPTC, XMP | With or without re-encoding the file |
Absolute paths are required, and Smol does not overwrite originals by default.
Beyond the files themselves
- Presets
- List, create, and remove Smol presets so one house standard is reusable across jobs.
- Watched folders
- List, add, update, and remove folders that process automatically.
- Clipboard
- Compress whatever is on the clipboard without a file ever hitting disk.
- Quick Actions
- Check, install, or remove the Finder Quick Action.
- Job control
- Plan, run, monitor, and cancel — every operation is cancellable mid-flight.
- Deliberately excluded
- Licence activation, licence deactivation, and installing updates are not exposed to agents.
Setup
Connect Antigravity to Smol.
- STEP 01
Update to Smol 1.0.35
Antigravity support does not exist in any earlier build. Let Smol’s built-in updater install 1.0.35, or download the current release for Apple Silicon or Intel.
- STEP 02
Open the Smol for AI panel
Launch Smol and select “Smol for AI” in the sidebar. The panel is titled “Connect AI tools to Smol” and lists each supported client with a live connection status.
- STEP 03
Click Connect on Google Antigravity
Smol writes its MCP server entry into Antigravity’s own MCP settings. Existing servers are preserved, and a settings file Smol cannot safely read is left untouched rather than overwritten.
- STEP 04
Hand your agent the guide, then a job
Use “Copy full AI guide” and paste it into Antigravity so the model knows every tool and setting. Then ask for a compression, conversion, upscale, metadata strip, or an exact target file size.
The same panel connects Claude Code and Codex, and the three can be connected at once. Smol implements the open Model Context Protocol, so other MCP-compatible clients can connect using the same mechanism.
Honest limits
When you do not need this.
Six situations where connecting Antigravity to Smol is the wrong move, or simply pointless.
You do not use Antigravity
Nothing here changes for you. Claude Code and Codex have connected to Smol since the MCP release, and the drag-and-drop app is unchanged. This is one more client, not a new product.
You have one file to deal with
Drag it onto the Smol window, or right-click it in Finder and use the Quick Action. Asking an agent to do it is strictly slower than doing it yourself.
You need this in CI
The MCP server lives inside the Smol desktop app, so the app has to be running on a Mac for an agent to reach it. A headless build server wants a container with the encoders baked in, not a GUI app.
You need a format Smol does not produce
There is no AVI output and no .pages support. Video output is mp4, mov, webm, and mkv. If your pipeline needs something outside the capability list, Smol will not fake it.
You want the agent to run the whole app
Licence activation, licence deactivation, and update installation are intentionally kept out of the MCP surface. An agent can process your media. It cannot manage your licence or push an update.
You are not on a Mac
Smol is macOS only — macOS 13 or later on Apple Silicon, macOS 14 or later on Intel. There is no Windows or Linux build, and the MCP server does not change that.
For the manual route, the help centre covers batch compression, removing EXIF data, and AI upscaling without an agent anywhere near them.
Available now
Smol 1.0.35, Apple Silicon and Intel.
Antigravity support is included at no extra cost and is rolling out now through Smol’s built-in updater. Smol is a one-time $29 purchase with future updates included — no subscription, no per-client AI add-on, and no usage metering on the MCP tools.
Questions
Smol, Antigravity, and MCP.
How do I connect Google Antigravity to Smol’s MCP server?
Update to Smol 1.0.35, open the “Smol for AI” panel in the app sidebar, and click Connect on Google Antigravity. Smol writes its own MCP server entry into Antigravity’s MCP settings for you — there is nothing to copy, paste, or hand-edit. The panel then shows a live connected status for that client.
Will connecting Smol overwrite my existing Antigravity MCP servers?
No. Smol adds itself alongside whatever you already have configured and keeps every other server intact. If Smol cannot safely read your existing MCP settings file, it declines to write rather than replacing the file. A config it cannot parse is left exactly as it was.
Do my files get uploaded anywhere when Antigravity uses Smol?
No. Smol is a local MCP server. Antigravity connects to the Smol app running on your Mac, not to a hosted processing service, and every file is read, encoded, and written on-device. That is the structural difference from cloud MCP media tools, and it is what makes the workflow usable for client work and material under NDA.
What can an Antigravity agent actually do with Smol?
Compress images, PDFs, video, and audio; convert between images, documents, spreadsheets, presentations, tables, and fonts; upscale images 2×, 3×, or 4×; strip EXIF, GPS, IPTC, and XMP metadata; and run Neural compression with an exact target size between 4 KB and 4096 KB. It can also plan, monitor, and cancel jobs.
Which version of Smol added Antigravity support?
Smol 1.0.35. Antigravity is not available in any earlier build. The release is rolling out now through Smol’s built-in updater and is available for both Apple Silicon and Intel Macs. The same update also refreshes the design of the AI access panel.
Is Antigravity support an extra cost?
No. Smol is a one-time $29 purchase that includes future updates. There is no subscription, no per-client AI add-on, and no usage metering on the MCP tools. Connecting Antigravity, Claude Code, and Codex at the same time costs nothing extra.
