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.

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"
