Post, schedule and run ads from Cursor

Cursor is an AI-first code editor whose agent reads MCP servers out of mcp.json. Hermoso shows up beside your repo, which is useful in a way that is easy to miss: the render, the caption and the code that references them end up in one place.

Hermoso is the marketing half: 301 tools over one OAuth’d MCP endpoint covering competitor ad research, finished image and video ad generation across 50+ models, publishing and scheduling to eight social channels, and campaign management on Meta, Google Ads, Microsoft Advertising, Reddit Ads, LinkedIn, Pinterest and ChatGPT Ads. One connection, and Cursor has all of it.

Connect Hermoso to Cursor

1. Create an API key. In Hermoso, open Settings → Agents & API keys and press ＋ Create API key. It looks like hmk_… and carries real spend authority, so treat it like a password.
2. Add it to ~/.cursor/mcp.json (or the project’s .cursor/mcp.json):

   { "mcpServers": { "hermoso": {
       "url": "https://app.hermoso.ai/mcp",
       "headers": { "Authorization": "Bearer <your key>" }
   } } }

3. Or use the one-click install from the MCP page. That deeplink installs the bare URL and leaves authentication to Cursor’s own OAuth flow instead of a pasted key — both work, they are just different prerequisites.
4. Ask Cursor for something. “Pull my three closest competitors’ longest-running ads and remix the best hook into a 9:16 video,” or “post this render to the channel.” The agent picks the tools; you approve the spend.

The config above is the path Hermoso publishes and tests. If you use the deeplink instead, Cursor performs dynamic client registration against our authorization server and you never hold a key.

Every channel Cursor can publish to

Each of these has its own page with that channel’s real caption cap, its real visibility options, what it refuses and why, and a worked example phrased for Cursor.

All eight queue through one schedule_post calendar with per-channel captions, and list_scheduled reports per-channel outcomes rather than a single green tick — “the job succeeded” and “the post went out” are different questions.

Two channels that are built but not offered

Being straight about this is worth more than a longer list. Two publishing surfaces exist in the codebase and are held back, each waiting on the platform rather than on us:

• Reddit — post_to_reddit is built and reddit_post_stats reads a post back, but Reddit’s Responsible Builder Policy requires explicit written approval before an app may use the Data API, and that ticket has not been granted. The connector is held back rather than offered as an OAuth screen leading to a dead API. Reddit Ads is a different connection and it is live — the full campaign tree, forecasting, targeting search, pixels and lead forms.
• Google Business Profile — post_to_google_business is built, with events, offers and a real call-to-action choice, and so are the listing insights. Google allowlists the Business Profile API per project and the default quota is zero, so every call would 403 for every user. It stays gated until Google grants the project access.

A connector that would hand you a successful OAuth and a dead API is worse than one that is not offered yet, so neither is listed as available.

Three things to type once it is connected

1. Research. “Who are my three closest competitors, and what are their longest-running Meta ads? Tell me which hook keeps repeating.” — walks find_competitors → pull_competitor_ads → mine_angles.
2. Create. “Make me a 9:16 UGC video ad using that hook, with my real product photo and captions burned in.” — walks get_brand → plan_ad → render_ad, and hands back a finished mp4 URL.
3. Ship. “Schedule it to Instagram and TikTok for Tuesday 9am, and build a paused Meta campaign around it targeting the US at $30 a day.” — walks schedule_post → create_meta_campaign → create_meta_ad. The campaign is created paused; nothing spends until you say so.

What Cursor cannot do on its own

An agent with a budget is only useful if the blast radius is bounded, so the fence is in the server rather than in a prompt. Every ad campaign, ad set, ad group and ad is created paused, and the status switches that arm real money refuse to run without an explicit confirmation flag. Every render is quoted first — hermoso_capabilities publishes each model’s exact credit cost before anything spends — and credits are reserved before the first provider call and settled at the exact cost afterwards, so a failed dispatch refunds rather than leaving you billed for nothing. Deletes are confirm-gated too, and every campaign tree is read back from the ad platform before your agent tells you what it built.

One step is deliberately not headless: linking an account is an OAuth consent screen, so you connect the channel once in a browser. Everything after that is a tool call.

Beyond publishing

Publishing is the last step, and it is the smallest one. The same connection gives Cursor the Meta, Google and LinkedIn ad libraries plus organic TikTok, Instagram, YouTube, Reddit and Threads for research; 50+ image, video, voice and writing models on a single credit meter, with UGC avatars, dubbing, upscaling and native HTML ad formats; and the full campaign tree on seven paid platforms. There are no per-vendor API keys to hold and no separate app to learn.

Frequently asked questions

Can Cursor post to social media?

Yes, once you connect Hermoso's MCP server. Cursor can then publish to Facebook, Instagram, Threads, TikTok, YouTube, X, LinkedIn and Pinterest — and schedule to all eight from one queue with per-channel captions.

How do I add Hermoso to Cursor?

Create an API key in Hermoso under Settings → Agents & API keys, then point Cursor at https://app.hermoso.ai/mcp with an Authorization: Bearer header. The config above is the path Hermoso publishes and tests. If you use the deeplink instead, Cursor performs dynamic client registration against our authorization server and you never hold a key.

Can Cursor run my Meta and Google ad campaigns?

Yes. Cursor can build the whole tree on Meta, Google Ads, Microsoft Advertising, Reddit Ads, LinkedIn, Pinterest and ChatGPT Ads. Everything is created paused with no caller override, the only switches that arm real money are confirm-gated, and the summary you get is built from a read-back of what the platform actually stored.

Does using Hermoso from Cursor cost extra?

No. There is one credit meter and it does not care which client called. A free account starts with 25 credits plus 250+ earnable; paid plans are $19, $49 and $149 a month for 1,000, 3,000 and 10,000 credits. Publishing is free on every channel except X, which bills per call because X charges us per API request.
