Technical details

Server and authentication

Hosted connectors (Claude.ai, ChatGPT) use OAuth 2.0 with PKCE. Local clients (Claude Desktop, Cursor) can connect with an API key via mcp-remote.

  • MCP endpoint: https://mcp.energy-data.io/mcp
  • OAuth issuer: https://app.energy-data.io
  • Developer portal: https://app.energy-data.io/developer
  • Transport: Streamable HTTP
  • Scopes: degree_days, usage_read (optional)

Available tools

Three tools are exposed on the MCP server:

  • get_degree_days — heating or cooling degree days for one location and date range
  • estimate_degree_day_cost — free preview of query cost before running
  • get_api_usage_summary — current allowance and recent usage (requires usage_read scope)

Credit rates (mean method)

MCP connector queries use your MCP day allowance. For minmax and integration methods, use the REST API — see API pricing.

  • integration: 1.0 credits per day per location
  • mean: 0.01 credits per day per location
  • minmax: 0.02 credits per day per location
