Add Sprites to Gemini
Available on Gemini CLI, free and paid, on macOS, Linux and Windows. You need a Sprites account with Reddit Ads already connected — the connector acts on that connection, so Gemini never handles a Reddit credential.
Open the Gemini settings file
Gemini CLI keeps MCP servers in its settings JSON. Use ~/.gemini/settings.json to have Sprites available everywhere, or .gemini/settings.json inside a project to scope it there.
Gemini CLI~/.geminisettings.jsonAdd Sprites under mcpServers
Use httpUrl, not url or command — that is the key Gemini CLI reads for a streamable HTTP endpoint. A url entry is treated as SSE and a command entry as a local process, and neither is what this is.
~/.gemini/settings.json{ "mcpServers": { "sprites": { "httpUrl": "https://mcp.sprites.ai/mcp" } } }Sign in
Gemini CLI supports OAuth 2.0 for remote servers and discovers the authorization server from the endpoint itself. Restart the CLI, and the first call opens a browser for the Sprites consent screen; the token is stored in ~/.gemini/mcp-oauth-tokens.json.

Type /mcp in the CLI to list every server and the tools it exposes, or run gemini mcp list from a shell to see connection status without opening a session.
Terminalgemini mcp list
Run the first prompt
Ask Gemini 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.
Run `gemini mcp list`, or type /mcp inside the CLI — Sprites should show as connected with its tools listed.
What Gemini can do with Reddit Ads
The same doors, whichever client you are in. The account and the analytics are already Google: Gemini reads Google Ads and GA4 alongside Search Console without leaving the family it belongs to.
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
Gemini 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 Gemini
Three things go wrong in this client specifically, and each has a one-line fix.
Gemini connects but reports no tools.
The entry is probably using url rather than httpUrl, so the CLI is speaking SSE to a streamable HTTP endpoint. Change the key and restart.
Edits to settings.json do nothing.
The CLI reads its settings at startup. Restart it, then re-check with /mcp.
A project file and your home file disagree.
.gemini/settings.json in the working directory takes precedence. Keep Sprites in one of the two rather than both.
Reddit Ads and Gemini: questions
Which URL do I paste into Gemini?
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 Gemini change my Reddit Ads account without asking?
Gemini 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. Gemini never sees a credential for it.
Why Gemini for Reddit Ads specifically?
The account and the analytics are already Google: Gemini reads Google Ads and GA4 alongside Search Console without leaving the family it belongs to.
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 Gemini connector reaches every other channel — nothing else to add.
