mcp-nrel

NREL MCP — wraps the US National Renewable Energy Laboratory developer API

Part of Pipeworx — an MCP gateway connecting AI agents to 965+ live data sources.

Tools

Quick Start

Add to your MCP client (Claude Desktop, Cursor, Windsurf, etc.):

{
  "mcpServers": {
    "nrel": {
      "url": "https://gateway.pipeworx.io/nrel/mcp"
    }
  }
}

Or connect to the full Pipeworx gateway for access to all 965+ data sources:

{
  "mcpServers": {
    "pipeworx": {
      "url": "https://gateway.pipeworx.io/mcp"
    }
  }
}

Using with ask_pipeworx

Instead of calling tools directly, you can ask questions in plain English:

ask_pipeworx({ question: "your question about Nrel data" })

The gateway picks the right tool and fills the arguments automatically.
