Complete MCP server exposing 23 AWS Budgets API operations to AI agents.

⚡ Quick Setup

1. Import this workflow into your n8n instance
2. Credentials Add AWS Budgets credentials
3. Activate the workflow to start your MCP server
4. Copy the webhook URL from the MCP trigger node
5. Connect AI agents using the MCP URL

🔧 How it Works

This workflow converts the AWS Budgets API into an MCP-compatible interface for AI agents.

• MCP Trigger: Serves as your server endpoint for AI agent requests • HTTP Request Nodes: Handle API calls to https://budgets.amazonaws.com • AI Expressions: Automatically populate parameters via $fromAI() placeholders • Native Integration: Returns responses directly to the AI agent
