For ChatGPT & Claude
ChargingAtlas MCP server
ChargingAtlas runs a free, public Model Context Protocol (MCP) server, so AI assistants like ChatGPT and Claude can answer EV-charging questions straight from the U.S. Department of Energy's NREL data — every public station across all 50 states + DC. No app, no login.
Endpoint
https://mcp.chargingatlas.com
Streamable HTTP (JSON-RPC), no authentication — it's public DOE/NREL data. Read-only.
What you can ask
- "EV charging in Austin, TX"
- "Nearest fast chargers to me" (with your location)
- "Which California cities have NACS connectors and free charging?"
- "How many public charging stations does ChargingAtlas cover?"
Tools
| Tool | What it does |
|---|---|
search | Find US cities by name — returns an id you pass to fetch. (ChatGPT/Deep-Research compatible.) |
fetch | The full EV-charging summary for a city id. (ChatGPT/Deep-Research compatible.) |
get_city_charging | A city's public charging: station count, Level 2 vs DC fast, networks, connectors, free vs paid, notable stations. |
search_cities | Find covered cities by name, optionally within a state. |
list_state_cities | Every covered city in a state, with station counts. |
find_charging | Filter/rank cities — by connector (J1772/CCS/NACS), network, DC-fast, or free charging. |
nearest_stations | The closest public stations to a latitude/longitude. |
coverage_stats | What's covered: states, cities, total stations, and the data date. |
How to connect
ChatGPT
Settings → Connectors (developer mode) → add a custom connector and paste the endpoint above.
No authentication. The search and fetch tools make it work with Deep Research.
Claude
Add it as a custom MCP server (Claude Desktop config or the claude.ai connectors settings) using the endpoint above — it needs no API key.
Prefer to just browse? Use the interactive map or find charging near you. Machines can also read our llms.txt.
Data: U.S. DOE / NREL Alternative Fuels Data Center. The MCP reports only what NREL records — it is not a live-availability map, so confirm a charger is working in the network's own app.
