Synter Ads MCP Server

Synter MCP Server

The MCP extension Claude doesn't want you to use.

Because once you install it, your AI agent can spend real money.

Create campaigns. Adjust budgets. Pause underperformers. Generate creatives. Pull performance data. All through natural conversation—across Google, Meta, LinkedIn, Microsoft, Reddit, TikTok, and more.

This is the first Model Context Protocol (MCP) server that gives AI agents a credit card.

Why Synter?

Most advertising MCP servers are read-only and single-platform. Synter is the only cross-platform ad management MCP server with full read + write capabilities:

One MCP server. Every ad platform. Read and write.

---

⚠️ Fair Warning

Your AI agent will be able to:

• Create campaigns that immediately start spending your budget
• Adjust bids that affect how much you pay per click
• Pause campaigns (sometimes that's a good thing)
• Add keywords that change who sees your ads
• Generate creatives and upload them to your accounts

We built in confirmations for destructive actions. But still—maybe don't give this to an agent you just met.

  "mcpServers": {
    "synter": {
      "command": "npx",
      "args": ["@synterai/mcp-server"],
      "env": {
        "SYNTER_API_KEY": "syn_your_api_key_here"
      }
    }
  }
}

Remote (Streamable HTTP) — For ChatGPT, n8n, Zapier, or any MCP client that supports HTTP transport:

Header: X-Synter-Key: syn_your_api_key_here

No local install needed. Works with any MCP client that supports Streamable HTTP transport.

Restart your AI client and start chatting:

"Show me all my Google Ads campaigns"

"Create a search campaign for 'project management software' with a $50/day budget"

No Ads Experience? No Problem.

If you've never run ads before, here's what you need to know:

What is a Campaign?

A campaign is like a project folder. It contains your ads, who sees them, and how much you spend.

Campaign: "Q1 Lead Generation"
├── Budget: $50/day
├── Targeting: USA, people searching "project management"
└── Ads: Headlines, descriptions, images

What Platforms Can I Use?

Campaign Types Explained

Search Campaigns — Your ad shows when someone Googles specific keywords.

• Example: Someone searches "best CRM software" → Your ad appears

Display Campaigns — Image ads shown across websites and apps.

• Example: Banner ad on a news site

Performance Max (PMax) — Google's AI shows your ads everywhere (Search, YouTube, Display, Gmail, Maps).

• Example: Google figures out the best placements for you

Video Campaigns — Video ads on YouTube and partner sites.

• Example: 15-second ad before a YouTube video

Common Terms

First Campaign Checklist

Before creating your first campaign, you'll need:

1. ✅ A landing page URL where people will go when they click
2. ✅ An idea of who you want to reach (location, interests)
3. ✅ A daily budget you're comfortable with ($10-50 to start)
4. ✅ Some headlines and descriptions for your ad

Pro tip: Start with a Search campaign on Google. It's the easiest to understand and shows ads to people already looking for what you offer.

Example Conversations

Create Your First Campaign

You: Create a Google Search campaign for my SaaS product. Target people searching for "team collaboration software" and "project management tools". Budget is $25/day. Landing page is https://myapp.com/signup

Agent: I'll create a Search campaign with those keywords. What headlines should I use? Here are some suggestions:

• "Team Collaboration Made Simple"
• "Project Management for Modern Teams"
• "Start Free - No Credit Card"

Check Performance

You: How are my campaigns doing this week?

Agent: Here's your performance for the last 7 days:

Campaign	Spend	Clicks	Conversions	ROAS
Brand Search	$142	89	12	4.2x
Competitor Keywords	$98	45	3	1.5x
Display Retargeting	$67	234	8	2.8x

The "Competitor Keywords" campaign is underperforming. Want me to pause it or adjust the targeting?

Add Negative Keywords

You: I'm getting clicks for "free project management" but we don't have a free tier. Block those.

Agent: Added "free" as a negative keyword to your campaign. This will stop your ads from showing for any search containing "free".

Generate Ad Creative

You: I need a display ad image for a marketing automation product. Dark theme, professional, 1200x628.

Agent: Generating your image with Imagen 4...

Created: "Marketing automation dashboard with data visualization on dark background" Asset saved and ready to use in your next Display campaign.

Troubleshooting

3. Complete the OAuth authorization
