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

VerifiedStreamable HTTPWeb executableCloud & InfrastructureData & Analytics

Overview

AI-generated overview

Remote MCP server that wraps the US National Renewable Energy Laboratory developer API, letting an assistant query NREL renewable energy data.

What you can do
Query US National Renewable Energy Laboratory data through the wrapped NREL developer API, such as solar resource and PV performance figures (the README shows a pvwatts example with latitude, longitude and system capacity). Ask questions in plain English through the gateway's ask_pipeworx tool, which selects a tool and fills arguments automatically. Search available tools and packs through the gateway. Call tools directly over HTTP when no MCP client is used.
When to use it
Useful when you need US renewable energy reference data, such as solar or PV estimates, inside an assistant conversation, and prefer a hosted endpoint over running a local server.
Requirements
A remote MCP endpoint at the Pipeworx gateway; no local runtime or package. The README states no account is needed for the first calls, and the manifest declares no authentication, environment variables or headers.
Before you install
Requests go through the third-party Pipeworx gateway, which sees your queries and arguments. The README notes only the first calls are free without an account, so usage beyond that may require an account or payment. The tool list is not published, so confirm available tools and any limits before relying on it.

Installation

In SourceWeft

  1. Open Nrel in the dashboard and add it to a workspace.
  2. Enable the server for the chats that should use its tools.

Web executable via Streamable HTTP. Remote servers run from the web runtime once configured in a workspace.

Use with an agent

Paste this prompt into Claude Code, Codex, Cursor or another agent — or into SourceWeft chat. The agent reads this server's install guide, shows you its publisher, endpoint and sign-in, and adds it to your client once you agree. Keys never go into a command.

Read https://sourceweft.com/mcp/io.github.pipeworx-io%2Fnrel/install.md and connect the MCP server it describes to my client. Before changing any config, show me its publisher, endpoint and sign-in method and wait for my OK. Never put an API key in a command or in a file I would commit; ask me where it should come from.

Read the install guide the agent follows

Other MCP clients

Add this to your client's mcpServers config.

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

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

Tools

ToolDescription

Quick Start

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

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

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

json
{  "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.

curl -X POST https://gateway.pipeworx.io/v1/tools/pvwatts \  -H 'Content-Type: application/json' \  -d '{"lat":40,"lon":-105.25,"system_capacity":4}'

No account needed for the first calls. Inspect any tool: GET https://gateway.pipeworx.io/v1/tools/pvwatts. Find one: POST https://gateway.pipeworx.io/v1/tools/search_packs with {"query":"..."}.
