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

Alex Prompter's viral thread on using autonomous agents 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 Synter MCP to create an AI marketing agent that manages your advertising 24/7.

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

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...

Synter MCP 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

Create a SKILL.md runbook that teaches OpenClaw when to use Synter MCP for campaign work across Google, Microsoft, Meta, LinkedIn, Reddit, TikTok, X, Amazon Ads, Amazon DSP, Spotify, Pinterest, Snapchat, The Trade Desk, DV360, and StackAdapt:

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

# Create the OpenClaw skill
cat > SKILL.md <<'EOF'

# Synter Ads

Use Synter MCP for campaign reads, campaign creation, budget changes, pause/enable actions, audience sync, conversion tracking checks, reporting, and creative generation.

Rules:
- Scope every action to the selected customer/account.
- Start new campaigns paused unless explicitly approved.
- Use content landing pages with UTM parameters.
- Never send paid traffic directly to /get-started, /signup, /onboarding, or cross-domain go/ redirects.
- Verify tracking before conversion bidding.
- Prefer shared tools first: list_campaigns, pause_campaign, enable_campaign, update_campaign_budget.
- If a shared tool does not support a platform, use run_ppc_script with the platform-specific script.

# Register the remote MCP server for the skill
cat > mcp.json <<'EOF'
{
  "mcpServers": {
    "synter": {
      "command": "npx",
      "args": ["mcp-proxy", "--transport", "streamablehttp", "--headers", "X-Synter-Key", "$SYNTER_API_KEY", "https://mcp.syntermedia.ai"]
    }
  }
}
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"

# Start the Synter operator 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"

Configure your agent to run marketing tasks automatically.

Daily Performance Reports

Automatic Budget Optimization

Competitor Monitoring

Your Synter operator now has access to 100+ actions:

Use list_available_scripts to see the full catalog.

AI Video Ad Generation

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

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

The barrier to entry just dropped to zero:

1. Sign up for Synter (free trial included)
2. Connect your ad accounts
3. Generate an API key
4. Install the Synter MCP skill
5. 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.
