Compatible with every major AI agent and IDE
What is the NREL Solar Resource MCP Server?
Connect your AI agent to the National Renewable Energy Laboratory (NREL) Solar Resource API to analyze solar potential and access historical radiation data through natural conversation.
What you can do
- Solar Irradiance — Retrieve average solar irradiance data including Direct Normal Irradiance (DNI), Global Horizontal Irradiance (GHI), and Tilt at Latitude for specific coordinates.
- NSRDB Queries — Search the National Solar Radiation Database for the nearest datasets based on latitude/longitude, address, or Well-Known Text (WKT) geometry.
- Data Sourcing — Identify specific satellite or station-based datasets for renewable energy research and site assessment.
How it works
- Subscribe to this server
- Enter your NREL API Key
- Start querying solar data from Claude, Cursor, or any MCP-compatible client
Who is this for?
- Energy Analysts — quickly assess the solar potential of specific geographic locations for project feasibility.
- Researchers — locate relevant NSRDB datasets for climate and energy studies without manual API calls.
- Engineers — retrieve precise irradiance metrics for solar installation planning directly in your workflow.
Built-in capabilities (2)
Get average solar irradiance data for a location
Query nearest NSRDB datasets for a location
Why Cursor?
Cursor's Agent mode turns NREL Solar Resource into an in-editor superpower. Ask Cursor to generate code using live data from NREL Solar Resource and it fetches, processes, and writes. all in a single agentic loop. 2 tools appear alongside file editing and terminal access, creating a unified development environment grounded in real-time information.
- —
Agent mode turns Cursor into an autonomous coding assistant that can read files, run commands, and call MCP tools without switching context
- —
Cursor's Composer feature can generate entire files using real-time data fetched through MCP. no copy-pasting from external dashboards
- —
MCP tools appear alongside built-in tools like file reading and terminal access, creating a unified agentic environment
- —
VS Code extension compatibility means your existing workflow, keybindings, and extensions all work alongside MCP tools
NREL Solar Resource in Cursor
NREL Solar Resource and 4,000+ other MCP servers. One platform. One governance layer.
Teams that connect NREL Solar Resource to Cursor through Vinkius don't need to source, host, or maintain individual MCP servers. Every tool call runs inside a hardened runtime with credential isolation, DLP, and a signed audit chain.

Why teams choose Vinkius for NREL Solar Resource in Cursor
The NREL Solar Resource MCP Server runs on Vinkius-managed infrastructure inside AWS — a purpose-built runtime with per-request V8 isolates, Ed25519 signed audit chains, and sub-40ms cold starts. All 2 tools execute in hardened sandboxes optimized for native MCP execution.
Your AI agents in Cursor only access the data you authorize, with DLP that blocks sensitive information from ever reaching the model, kill switch for instant shutdown, and up to 60% token savings. Enterprise-grade infrastructure, zero maintenance.

How Vinkius secures
NREL Solar Resource for Cursor
Every tool call from Cursor to the NREL Solar Resource MCP Server is protected by DLP redaction, cryptographic audit chains, V8 sandbox isolation, kill switch, and financial circuit breakers.
Frequently asked questions
How do I get solar irradiance for a specific coordinate?
Use the get_solar_resource tool by providing the latitude and longitude. The agent will return average DNI, GHI, and Tilt at Latitude data for that location.
Can I search for solar data using a physical address instead of coordinates?
Yes! The query_nsrdb_data tool allows you to provide an address string. The system will locate the nearest NSRDB datasets associated with that address.
What types of data sources can I filter by in the NSRDB?
When using query_nsrdb_data, you can use the type parameter to filter results by 'satellite' or 'station' data sources.
What is Agent mode and why does it matter for MCP?
Agent mode is Cursor's autonomous execution mode where the AI can perform multi-step tasks: reading files, editing code, running terminal commands, and calling MCP tools. Without Agent mode, Cursor operates in a simpler ask-and-answer mode that doesn't support tool calling. Always ensure you're in Agent mode when working with MCP servers.
Where does Cursor store MCP configuration?
Cursor looks for MCP server configurations in a mcp.json file. You can configure servers at the project level (.cursor/mcp.json in your project root) or globally (~/.cursor/mcp.json). Project-level configs take precedence.
Can Cursor use MCP tools in inline edits?
No. MCP tools are only available in Agent mode through the chat panel. Inline completions and Tab suggestions do not trigger MCP tool calls. This is by design. tool calls require user visibility and approval.
How do I verify MCP tools are loaded?
Open Settings → Features → MCP and look for your server name. A green indicator means the server is connected. You can also check Agent mode's available tools by clicking the tools dropdown in the chat panel.
Tools not appearing in Cursor
Ensure you are in Agent mode (not Ask mode). MCP tools only work in Agent mode.
Server shows as disconnected
Check Settings → Features → MCP and verify the server status. Try clicking the refresh button.
