1. Import this workflow into your n8n instance
2. Credentials Add CarbonDoomsDay 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 CarbonDoomsDay 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://api.carbondoomsday.com/api
• AI Expressions: Automatically populate parameters via $fromAI() placeholders
• Native Integration: Returns responses directly to the AI agent

📋 Available Operations (2 total)

🔧 Co2 (2 endpoints)

• GET /co2/: Get CO2 Measurement by Date
• GET /co2/{date}/: CO2 measurements from the Mauna Loa observatory.

This data is made available through the good work of the people at the
Mauna Loa observatory. Their release notes say:

These data are made freely available to the public and the scientific
community in the belief that their wide dissemination will lead to greater
understanding and new scientific insights.

We currently scrape the following sources:

• co2_mlo_weekly.csv
• co2_mlo_surface-insitu_1_ccgg_DailyData.txt
• weekly_mlo.csv

We have daily CO2 measurements as far back as 1958.
