Post, schedule and run ads from OpenClaw

OpenClaw is a terminal agent that loads MCP servers from ~/.openclaw/openclaw.json. Because it can start a local process, it takes the keyless route: sign in once from the terminal and the same 681+ tools appear, with no secret in the file.

Hermoso is the marketing half: 681+ tools over one OAuth’d MCP endpoint covering competitor ad research, finished image and video ad generation across 50+ models, publishing and scheduling to ten social channels, and campaign management on Meta, Google Ads, Microsoft Advertising, Reddit Ads, LinkedIn, Pinterest, X Ads, TikTok Ads, Snapchat Ads, ChatGPT Ads and Apple Search Ads. One connection, and OpenClaw has all of it.

Connect Hermoso to OpenClaw

1. Install and sign in.

   npm install -g hermoso && hermoso auth login

   Your browser opens once. Nothing to create and nothing to paste: the credential is stored owner-only in ~/.hermoso/config.json. On a machine with no browser, hermoso auth login --token hmk_… takes a key from Settings → Agents & API keys instead.
2. Add it to ~/.openclaw/openclaw.json. No key goes in the file, because hermoso mcp reads the sign-in above:

   { "mcp": { "servers": { "hermoso": { "command": "npx", "args": ["-y", "hermoso", "mcp"] } } } }

3. Ask your agent 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.

Hermoso has no special relationship with OpenClaw and does not claim one. The shape above is quoted from OpenClaw's own MCP reference at docs.openclaw.ai/cli/mcp, read on 2026-08-23; it is documented rather than run here, which is why it is the published file shape and not a bespoke install command.

Every channel OpenClaw 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 OpenClaw.

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 OpenClaw 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 OpenClaw 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 eleven paid platforms. There are no per-vendor API keys to hold and no separate app to learn.

Frequently asked questions

Can OpenClaw post to social media?

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

How do I add Hermoso to OpenClaw?

Run npm install -g hermoso && hermoso auth login, then add hermoso under mcp.servers in ~/.openclaw/openclaw.json with command npx and args -y hermoso mcp. The browser sign-in stores the credential, so no key goes in the file. Hermoso has no special relationship with OpenClaw and does not claim one. The shape above is quoted from OpenClaw's own MCP reference at docs.openclaw.ai/cli/mcp, read on 2026-08-23; it is documented rather than run here, which is why it is the published file shape and not a bespoke install command.

Can OpenClaw run my Meta and Google ad campaigns?

Yes. OpenClaw can build the whole tree on Meta, Google Ads, Microsoft Advertising, Reddit Ads, LinkedIn, Pinterest, X Ads, TikTok Ads, Snapchat Ads, ChatGPT Ads and Apple Search 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 OpenClaw 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.
