Synter MCP Server

The most complete MCP server for advertising.

Reporting across 19 ad platforms and full campaign creation on 14 of them (write actions on 16), spanning every major buying channel, with built-in confirmations for destructive actions.

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

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

Note: Synter-Media-AI/plugin is the canonical installable Claude plugin repo. The .claude-plugin/ copy in this repo is not the install source.

How Synter Compares

The official Google Ads MCP server is read-only by design: per Google's documentation, it is "strictly read-only" and "cannot modify bids, pause campaigns, or create new assets." Most third-party ad MCP servers cover a single platform. We built Synter to do both halves of the job, across every major buying channel, from one server.

Reporting coverage (19 platforms): Google Ads, Microsoft Ads (Bing), Meta (Facebook and Instagram), LinkedIn Ads, X (Twitter) Ads, Reddit Ads, TikTok Ads, Snapchat Ads, Pinterest Ads, Spotify Ads, Amazon Ads, Amazon DSP, Walmart Connect, Instacart Ads, Target Roundel, Criteo, The Trade Desk, Display & Video 360, and OpenAI Ads (ChatGPT).

Full campaign creation (14 platforms): Google Ads, Microsoft Ads, Meta, LinkedIn, X, Reddit, TikTok, Snapchat, Pinterest, Spotify, Amazon Ads (Sponsored Products, Brands, and Display), Amazon DSP, The Trade Desk, and OpenAI Ads. Display & Video 360 and StackAdapt additionally support write actions (pause, budget and line-item updates, audience upload) without campaign creation. The remaining 4 (Walmart Connect, Instacart, Target Roundel, and Criteo) are reporting-only today.

The npx package ships typed tools for the most common operations plus run_tool access to the full catalog of 140+ Synter tools. The remote server at https://mcp.syntermedia.ai/mcp/ exposes the full hosted tool set, including performance pulls for every platform above.

For registry-style MCP discovery, server.json is the machine-readable source of truth. Keep it aligned with package.json, manifest.json, and the setup examples in this README.

⚠️ 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.
