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:

Platforms	9+ (Google, Meta, LinkedIn, Microsoft, Reddit, TikTok, X, StackAdapt, TTD)	Google only	Amazon only	1-2
Create campaigns	✅	❌ Read-only	✅ Amazon only	❌
Adjust budgets	✅	❌	✅	❌
Pause campaigns	✅	❌	✅	❌
AI creative generation	✅ (Imagen 4, Veo, Flux)	❌	❌	❌
Bid optimization	✅	❌	❌	❌
AI Strategist	✅	❌	❌	❌
Open source	✅	✅	❌	Varies

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.

Quick Start

1. Get Your API Key

Sign up at syntermedia.ai and create an API key in the Developer Settings.

2. Configure Your AI Client

For Claude Desktop — Add to ~/Library/Application Support/Claude/claude_desktop_config.json:

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

For Cursor — Add to .cursor/mcp.json in your project:

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

For Amp — Add to .amp/settings.json:

{
  "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:

URL: https://mcp.syntermedia.ai/mcp/
Header: X-Synter-Key: syn_your_api_key_here

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

3. Start Using It

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"

"Pause the campaign that's overspending"

Prefer a full plugin? (Claude Code / Claude Desktop)

This package is the raw MCP server. If you use Claude Code or Claude Desktop, the Synter plugin wraps this same server with ready-made skills (/synter:launch, /synter:audience, /synter:optimize, …), specialized agents, and an approval-before-spend safety hook:

/plugin marketplace add Synter-Media-AI/plugin
/plugin install synter@synter

It also ships a headless Claude Agent SDK runner for automation. See the plugin repo or the Claude Plugin guide. Use this MCP package directly when you want just the tools, or are wiring another client.
