Which app do you use?

Pick your app above. We remember it, so next time the button says “Install in …”.

This address needs a key in a request header, which the add-connector menu cannot set. Use Claude Code, Cursor or VS Code instead.

Run this in your terminal

claude mcp add --transport http gridhub https://api.grid-hub.app/mcp --header 'Authorization: your-value'

Fill in the empty values before running it.

Open in Cursor

Or copy the settings yourself

Paste into .cursor/mcp.json in your project, or ~/.cursor/mcp.json

{
  "mcpServers": {
    "gridhub": {
      "url": "https://api.grid-hub.app/mcp",
      "headers": {
        "Authorization": "your-value"
      }
    }
  }
}

Your browser asks to open the app, then the app shows the settings and asks you to confirm. Key values are left empty for you to fill in.

Open in VS Code

Or copy the settings yourself

Paste into .vscode/mcp.json in your project

Common questions

Is GridHub Electricity Market Data safe?

It passed 1 of 1 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.

What keys or codes does it need?

You need to fill in: Authorization

Does it run on my computer or in the cloud?

It runs in the maker’s cloud. Connect over the internet with nothing to install, but what you send passes through the maker’s servers.

Is it still maintained?

The GitHub repo last changed –, and the latest version (1.0.2) reached the registry 2 months ago.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. It connects by URL, so apps that accept remote MCP servers work too, such as ChatGPT in developer mode.

What can I use instead?

GridHub MCP Server

Live and historical electricity market data for AI agents, over the Model Context Protocol.

Endpoint: https://api.grid-hub.app/mcp — hosted, Streamable HTTP, stateless. Nothing to install.

Covers 25 grid zones — US ISOs (CAISO, ERCOT, PJM, MISO, NYISO, ISO-NE, SPP), 12 European bidding zones, Great Britain, and the five Australian NEM regions — normalised into one JSON schema. Sourced from EIA, ENTSO-E, NESO, Elexon and AEMO; every response carries its licence and attribution.

Tools

Tool	What it returns
`get_zone_brief`	Current price / demand (and carbon intensity for GB) ranked against the zone's own last 30 days (percentile, vs-median, min/max), 24h trend, generation mix (GB, US-CAISO), and a one-sentence summary. Best for "is electricity cheap or clean in X right now?"
`get_latest`	Most recent value of every metric one zone publishes, with unit and timestamp
`get_history`	Time series for one metric over a start/end window (up to 31 days per call)
`get_map_snapshot`	Headline values for all 25 zones at once — compare or rank zones
`list_zones`	Zone ids, names, sources, currencies, licences (free)
`get_status`	Ingestion freshness per source and zone (free)

Access

Three levels, no signup needed to start:

Sample mode — connect with no credentials. Tools return real, current data, truncated (history capped at 50 rows; brief returns one context block). Results are clearly marked.
Free API key — 500 requests/day. Instant email signup at grid-hub.app/developers, or POST https://api.grid-hub.app/v1/keys/signup with {"email": "..."}. Send as Authorization: Bearer .
x402 pay-per-call — USDC on Base, $0.001–$0.02 per call, via the X-PAYMENT header. See the x402 flow.

Setup

Claude Code

claude mcp add --transport http gridhub https://api.grid-hub.app/mcp \

--header "Authorization: Bearer YOUR_KEY"

Cursor / Windsurf / VS Code (mcp.json)

"mcpServers": { "gridhub": { "url": "https://api.grid-hub.app/mcp", "headers": { "Authorization": "Bearer YOUR_KEY" } } } }

Claude Desktop / claude.ai — add https://api.grid-hub.app/mcp as a custom connector. These clients don't send custom headers; pass the key as the optional api_key tool argument, or use sample mode.

Local stdio bridge — for clients that only support local (stdio) servers. It proxies to the hosted endpoint via mcp-remote; nothing runs locally except the bridge.

"mcpServers": { "gridhub": { "command": "npx", "args": ["-y", "github:jalcodev/gridhub-mcp"], "env": { "GRIDHUB_API_KEY": "YOUR_KEY" } } } }

Or with Docker: `docker build -t gridhub-mcp . && docker run -i -e GRIDHUB_API_KEY=YOUR_KEY gridhub-mcp`. Omit the key for sample mode.

Any client, no key — omit the header. You'll get sample-mode data and a note on how to upgrade.

Protocol

Streamable HTTP, stateless: one JSON-RPC message per POST, JSON response. No sessions, no SSE.
Speaks MCP 2026-07-28 (header-mirrored requests, no handshake) and 2025-03-26 through 2025-11-25 (initialize handshake).
Tool results include structuredContent alongside the text block.
Rate limits and quotas are those of the underlying REST API; the MCP layer adds none of its own.
