Add this to your client's MCP configuration (Claude Desktop: claude_desktop_config.json; Cursor: .cursor/mcp.json; VS Code and others use the same "mcpServers" shape).

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

ToolWhat it returns
get_zone_briefCurrent 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_latestMost recent value of every metric one zone publishes, with unit and timestamp
get_historyTime series for one metric over a start/end window (up to 31 days per call)
get_map_snapshotHeadline values for all 25 zones at once — compare or rank zones
list_zonesZone ids, names, sources, currencies, licences (free)
get_statusIngestion freshness per source and zone (free)

Access

Three levels, no signup needed to start:

  1. 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.
  2. 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 <ghk_key>.
  3. 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.
