Add Sprites to Cursor
Available on Any Cursor plan that allows MCP servers, on desktop and on Cursor web agents. You need a Sprites account with Reddit Ads already connected — the connector acts on that connection, so Cursor never handles a Reddit credential.
Write the config
Put the entry in ~/.cursor/mcp.json to have Sprites available in every project, or in .cursor/mcp.json inside one repo to scope it there.
~/.cursor/mcp.json{ "mcpServers": { "sprites": { "url": "https://mcp.sprites.ai/mcp" } } }Or add it from the UI
Cursor lists MCP servers under Customize in the sidebar; adding one there writes the same file.

Cursor finds the Sprites authorization server from the endpoint's protected-resource metadata, registers itself, and opens a browser for the consent screen. Desktop completes on http://localhost:8787/callback and web agents on cursor.com; both are pre-registered, so there is nothing to allowlist.

A project-scoped .cursor/mcp.json is worth committing: every teammate who opens the repo gets the same connector and signs in as themselves. The file holds a URL and nothing else — the token is per person and never touches the config.
Run the first prompt
Ask Cursor 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 Reddit ad groups 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 Reddit ad groups with spend and no conversions this month.
- With Sprites, launch a Reddit campaign across our top 8 communities at $60/day.
Open Cursor Settings → MCP and confirm sprites is listed as connected with its tool count.
What Cursor can do with Reddit Ads
The same doors, whichever client you are in. The campaign and the page it points at live in the same window: change the pricing copy, then have Sprites update the ads that quote it, without a second tool.
Performance by ad group
CPA, CTR, leads and ROAS by campaign, ad group and ad. Give each community its own ad group and one expensive subreddit stops hiding inside a campaign average.
Find the right rooms
The subreddits where your problem is actually discussed, with the threads and phrasing to prove it, 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
Ad groups with clicks and no conversions, named with the spend attached.
Know what the audience says
Pain points and verbatim phrasing from the threads in your target communities, turned into hooks you can test.
Launch around a list
A campaign whose structure follows the community list rather than fighting it.
How approvals work here
Cursor renders tool results as text, so a Reddit change comes back written out rather than as a card. The approval waits for you in Sprites — open it there and the same run continues. Nothing is applied until you approve it.
What it reads
- Campaigns, ad groups, ads and community targeting
- Spend, CTR, conversions, CPA, leads and ROAS
- Performance by campaign, ad group and ad
- 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 Cursor
Three things go wrong in this client specifically, and each has a one-line fix.
The Connect button does nothing and no request is made.
A known Cursor issue on some builds. Update Cursor, then remove and re-add the server; if it persists, restart Cursor with the config already in place so the connection is made at startup.
Cursor authenticates but every call comes back unauthorized.
The token was issued for a different address. Delete the server entry, restart Cursor, and re-add it with the exact endpoint above — every grant is bound to that one URL, so a variant of it will not be honoured.
The agent invents ad-platform tools instead of calling Sprites.
Name it: "use Sprites to…". Cursor ranks its own tools first, and a generic phrasing loses to the built-in search.
Reddit Ads and Cursor: questions
Which URL do I paste into Cursor?
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 Cursor change my Reddit Ads account without asking?
Cursor renders tool results as text, so a Reddit change comes back written out rather than as a card. The approval waits for you in Sprites — open it there and the same run continues. Nothing is applied until you approve it.
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. Cursor never sees a credential for it.
Why Cursor for Reddit Ads specifically?
The campaign and the page it points at live in the same window: change the pricing copy, then have Sprites update the ads that quote it, without a second tool.
Is there an official Reddit Ads MCP server?
No. Reddit has not published an MCP server for its Ads API; only community wrappers exist, which you host and hold the credentials for yourself. Sprites is a hosted MCP server that reaches Reddit Ads alongside Google, Meta, LinkedIn and TikTok.
Can it target individual subreddits?
Yes. Ad groups are built with community targeting, and when each community gets its own ad group, CPA is read community by community — which matters, because cost varies widely from one subreddit to the next.
Keep going
The same Cursor connector reaches every other channel — nothing else to add.
