OpenClaw + Synter MCP: Build Your Own 24/7 AI Marketing Agent

The Viral Stack

Alex Prompter's viral thread on using OpenClaw for guerrilla marketing just crossed 500K views. Everyone's running it to check flight prices and manage calendars. But we've been using it for something more interesting: fully autonomous ad campaign management.

This guide shows you exactly how to set up OpenClaw with Synter MCP to create an AI marketing agent that manages your advertising 24/7.

What You're Building

By the end of this tutorial, you'll have:

An always-on AI agent running on your infrastructure (or Cloudflare for $5/month)
Access to 100+ advertising actions across Google, Meta, LinkedIn, Reddit, and more
Automated daily performance reports delivered to Slack or Telegram
Proactive budget optimization that adjusts spend based on ROAS
AI-generated creatives when you need fresh ad assets

The Stack

OpenClaw: Open-source AI assistant that runs 24/7 on your server (100K+ GitHub stars)
Synter MCP: Model Context Protocol server with 100+ advertising tools
Runtime: DigitalOcean droplet, Mac Mini, or Cloudflare Workers (Moltworker)

Step 1: Get Your Synter API Key

First, create an account at syntermedia.ai and connect your ad accounts (Google Ads, Meta, LinkedIn, etc.).

Then go to the Developer Portal and generate an API key.

# Your API key looks like this
syn_live_abc123xyz...

Step 2: Install OpenClaw

OpenClaw runs on any Linux server, Mac, or Raspberry Pi. You can also use Cloudflare Workers via Moltworker.

Option A: Self-Hosted (VPS)

Spin up a $6/month DigitalOcean droplet and run:

# SSH into your server
curl -fsSL https://get.moltbot.dev | bash

# Run the onboarding wizard
moltbot onboard

Option B: Cloudflare Workers

No hardware needed. $5/month minimum:

npx moltworker init my-marketing-agent
cd my-marketing-agent
npx wrangler deploy

Step 3: Install the Synter MCP Skill

Create a custom skill that gives your agent access to all 100+ advertising actions:

# Create a new skill directory
mkdir -p ~/.moltbot/skills/synter-ads
cd ~/.moltbot/skills/synter-ads

# Create the skill manifest
cat > skill.json <<'EOF'
{
  "name": "synter-ads",
  "description": "Manage advertising campaigns across Google, Meta, LinkedIn, and more",
  "mcp": {
    "command": "npx",
    "args": ["mcp-proxy", "--transport", "streamablehttp", "--headers", "X-Synter-Key", "$SYNTER_API_KEY", "https://mcp.syntermedia.ai/mcp/"]
  }
}
EOF

Set your API key as an environment variable:

# Add to your .bashrc or .zshrc
export SYNTER_API_KEY="syn_live_your_key_here"

# Or for Moltworker, add to wrangler.toml:
[vars]
SYNTER_API_KEY = "syn_live_your_key_here"

Step 4: Start Your Agent

# Start OpenClaw with Synter skill
moltbot start --skills synter-ads

# For 24/7 operation, install as a service:
moltbot service install

Message your bot on Telegram and ask: "Show me my Google Ads performance for the last 7 days"

Step 5: Set Up Automated Workflows

Configure your agent to run marketing tasks automatically.

Daily Performance Reports

“Every morning at 8am, pull performance data for all my ad platforms and send me a summary. Include spend, ROAS, and top 3 performing campaigns.”

Automatic Budget Optimization

“Monitor my campaigns. If any campaign has ROAS below 2.0 for 3 consecutive days, pause it. If any has ROAS above 4.0, increase its daily budget by 20%.”

Competitor Monitoring

“Monitor Ridge Wallet's Meta ads. When they launch new creatives, analyze the messaging and generate similar ad concepts for my brand.”

Available Synter MCP Actions

Your OpenClaw agent now has access to 100+ actions:

Category	Actions
Performance Data	`pull_google_ads_performance`, `pull_meta_ads_performance`, `pull_linkedin_ads_performance`
Campaign Management	`pause_campaign`, `update_campaign_budget`, `list_campaigns`
Campaign Creation	`google_ads_create_search_campaign`, `google_ads_create_pmax_campaign`, `meta_ads_create_campaign`
AI Creatives	`generate_image`, `generate_video_ad`, `competitor_inspired_creative`
Tracking	`gtm_create_conversion_tag`, `gtm_publish`, `ga4_run_report`

Real-World Examples

AI Video Ad Generation

“Generate a 15-second video ad promoting Synter. Use the problem-solution concept. Upload it to YouTube and create a Demand Gen campaign with a $50/day budget.”

Synter uses Veo 3.1 to generate the video, uploads to YouTube, and creates the full campaign — all in one prompt.

Cross-Platform Budget Reallocation

“I have $5K/month to spend across Google and Meta. Analyze performance weekly and reallocate budget to whichever platform has better ROAS.”

Security Notes

API keys are scoped: Your Synter API key only accesses your connected accounts
Revocable anytime: Rotate or revoke keys from the Developer Portal
Credit-based: Actions cost credits, so runaway agents can't rack up unlimited API calls
OpenClaw runs locally: Your data stays on your infrastructure

Get Started

The barrier to entry just dropped to zero:

Sign up for Synter (1,000 free credits)
Connect your ad accounts
Generate an API key
Install OpenClaw + Synter MCP skill
Tell your agent what to do

Your marketing now runs 24/7. While you sleep, your agent is pulling reports, optimizing budgets, pausing losers, and scaling winners.

That's the unfair advantage.
