About Nrel

Nrel is an MCP server wrapping the US National Renewable Energy Laboratory developer API for users who need its data. The README shows gateway-based questions and an example call to a photovoltaic output estimation tool.

Key features

  1. 01Wraps the NREL developer API
  2. 02Ask questions through the gateway
  3. 03Includes a photovoltaic estimate example

Use cases

  1. 01Query Nrel data through the gateway
  2. 02Estimate photovoltaic output with pvwatts

MCP support

It provides an MCP client connection through Pipeworx and can also be accessed via the full gateway. The README does not list its dedicated tools.

Configuration

Remote servers need no local install. Pick your client, then copy the config or install in one click.

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.

ToolDescription

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.

New to MCP?

From what the protocol is to installing your first server, these answers cover most first questions.

An open protocol that defines how AI applications connect to external tools and data in a uniform way. Clients talk to the model; MCP servers provide tools, resources and prompt templates. They exchange standard messages, so one server can be reused by many clients.
