Add Sprites to Google Antigravity
Available on Antigravity 2.0, Antigravity IDE, Antigravity CLI and the Antigravity SDK. You need a Sprites account with Reddit Ads already connected — the connector acts on that connection, so Google Antigravity never handles a Reddit credential.
Open the shared MCP config
All four Antigravity surfaces read one file. In the IDE, click … at the top of the agent side panel, choose MCP Servers, then Manage MCP Servers, then View raw config. The file itself is ~/.gemini/config/mcp_config.json, or .agents/mcp_config.json inside a workspace.
Antigravity IDE…MCP ServersManage MCP ServersView raw configAdd Sprites with serverUrl
Antigravity requires serverUrl for any remote connection. Its documentation is explicit that the url and httpUrl keys other clients use are not supported here, and an entry using them is skipped rather than reported.
~/.gemini/config/mcp_config.json{ "mcpServers": { "sprites": { "serverUrl": "https://mcp.sprites.ai/mcp" } } }Sign in
Antigravity registers itself with the Sprites authorization server automatically and completes the flow at its own callback. Save the file, reopen Manage MCP Servers, and connect.

AllowCancelUse it from any surface
Because the configuration is shared, the CLI and the SDK pick up the same server with no second step. Name the surface you are on when you follow an instruction — the products differ even though the config does not.
Run the first prompt
Ask Google Antigravity this. It routes to a Sprites door, which reads your Reddit Ads account and answers — no account to name, no confirmation to give first.
- With Sprites, which subreddits are converting and which are just clicking?
- Ask Sprites which communities discuss the problem our product solves.
- Use Sprites to rewrite our Reddit ad so it reads native to r/devops.
- Have Sprites pause the subreddits with spend and no conversions this month.
- With Sprites, launch a Reddit campaign across our top 8 communities at $60/day.
Reopen Manage MCP Servers; Sprites is listed with its tool count, and the same entry is live in the CLI.
What Google Antigravity can do with Reddit Ads
The same doors, whichever client you are in. One MCP configuration shared by the IDE, the CLI, the SDK and Antigravity 2.0, so the connector is added once and every surface has it.
Performance per community
CPA and engagement by subreddit, so a single expensive community stops hiding inside a campaign average.
Find the right rooms
The subreddits where your problem is actually discussed, sized and ranked before you target them.
Copy that does not get downvoted
Ad text drafted in the register of the community it runs in, not lifted from the Google Ads account.
Cut the tourist traffic
Communities with clicks and no conversions, named with the spend attached.
Read the comments
Engagement and sentiment on your own ads, which on Reddit is the earliest signal you get.
Launch around a list
A campaign whose structure follows the community list rather than fighting it.
How approvals work here
Google Antigravity renders tool results as text, so a Reddit change comes back written out rather than as a card. Nothing is applied until you approve it, and the approval waits for you in Sprites — open it there and the same run continues.
What it reads
- Campaigns, ad groups, ads and community targeting
- Spend, CPA, CTR, upvotes and comment engagement
- Per-subreddit performance breakdowns
- Public discussion in candidate communities
What it can change
- Create campaigns, ad groups and ads
- Community targeting, budgets, schedules and status
- Ad copy, drafted per community and approved before it runs
When it does not work in Google Antigravity
Three things go wrong in this client specifically, and each has a one-line fix.
The server is in the file but never appears.
It is almost certainly using url or httpUrl. Antigravity supports neither for remote servers; the key is serverUrl.
The IDE sees Sprites and the CLI does not.
A workspace .agents/mcp_config.json only applies inside that workspace. Put the entry in ~/.gemini/config/mcp_config.json to share it across surfaces.
Sign-in loops.
Antigravity completes OAuth at its own callback URL. Allow the browser redirect back to antigravity.google rather than cancelling it.
Reddit Ads and Google Antigravity: questions
Which URL do I paste into Google Antigravity?
https://mcp.sprites.ai/mcp. There is one endpoint and every client uses it — every OAuth grant is bound to exactly that address, so a variant of it will not be honoured.
Can Google Antigravity change my Reddit Ads account without asking?
Google Antigravity renders tool results as text, so a Reddit change comes back written out rather than as a card. Nothing is applied until you approve it, and the approval waits for you in Sprites — open it there and the same run continues.
Do I need a Reddit Ads API key or developer token?
No. Reddit Ads is connected once inside Sprites through Reddit Ads, and the connector acts on that connection. Google Antigravity never sees a credential for it.
Why Google Antigravity for Reddit Ads specifically?
One MCP configuration shared by the IDE, the CLI, the SDK and Antigravity 2.0, so the connector is added once and every surface has it.
Can it target individual subreddits?
Yes, and it reports on them individually too — which is the point, since community-level CPA varies more on Reddit than on any other channel.
Will it post organically to Reddit?
No. The connector runs Reddit Ads. Organic posting is deliberately out of scope: it is the fastest way to get an account banned.
Keep going
The same Google Antigravity connector reaches every other channel — nothing else to add.
