MCP Client is the Make app for building automation scenarios on top of external MCP servers.
The ‘Execute an action with AI’ module runs the AI steps inside those flows, and it just got an upgrade.
The MCP Client’s ‘Execute an action with AI’ module now lets you choose between Make AI Provider (OpenAI or Claude AI models) or your own OpenAI account.
What’s new
-
Make AI Provider: Access OpenAI and Claude AI models through Make credits, no external account or API key required. -
Bring your own OpenAI API key: Connect your existing OpenAI account and use the models you already pay for, with full control over spend. -
Keep MCP work in one place: Call AI actions right inside your MCP flow instead of bouncing between external tools.
Real-world use cases
-
Internal knowledge assistant: Pull context from an MCP server (like a Confluence or Notion), pass it to Make AI Agent to generate a clean, structured answer, and post the result directly to Slack, no manual copy-paste between tools. -
Customer support triage: Chain two Execute an action with AI modules: use a faster model in the first to classify incoming tickets by priority, then a more capable model in the second to generate a detailed summary for high-value cases before they land in your CRM or help desk. -
Automated content review: Connect your content pipeline to an MCP server, use OpenAI to check drafts against your brand guidelines, and route flagged items to a Google Sheet for human review, all without leaving Make.
More control over your AI setup means more precise, cost-efficient AI workflow automations. Let us know your thoughts!
Happy automating
