ISTERMCP

Model Context Protocol

Ister MCP server

Lets an AI assistant read Ister's regional GPU price indices: Claude Desktop, Claude Code, Cursor or any app that speaks the Model Context Protocol. It reads the API with your own key, so it sees what your key's tier sees.

read -rs "ISTER_API_KEY?Ister API key: "; echo
claude mcp add ister --scope user --env ISTER_API_KEY="$ISTER_API_KEY" -- npx -y @ister/mcp
unset ISTER_API_KEY
{
  "mcpServers": {
    "ister": {
      "command": "npx",
      "args": ["-y", "@ister/mcp"],
      "env": { "ISTER_API_KEY": "<your key>" }
    }
  }
}
{
  "mcpServers": {
    "ister": {
      "type": "stdio",
      "command": "npx",
      "args": ["-y", "@ister/mcp"],
      "env": { "ISTER_API_KEY": "<your key>" }
    }
  }
}

Your key from the API page, pasted at the prompt or in place of <your key>. Needs Node.js.

Your assistant, with Ister's MCP serverExample

What's an H100 on demand in Europe today?

ister_series gpu: H100, type: OD

€X.XX per GPU-hour: Europe's official print of the latest close, from N providers.

Where do the providers in that print deliver from?

ister_series gpu: H100, type: OD

From N countries: their ISO codes. The index names no provider.

And in US dollars?

ister_series gpu: H100, type: OD

$X.XX per GPU-hour, at the ECB's euro reference rate.

Example: the assistant answers with the latest print's figures, read from the API.

What it does

  • Runs on your computer. Your assistant's app starts it and talks to it directly.
  • Calls Ister's API over HTTPS with your key, and nothing else. The key stays in memory.
  • Reads only. Each answer is the API's own JSON; when the API refuses, the assistant gets its reason.
  • Reads what your key's tier reads: a free key, the H100 and B200 series of every index for 7 days; a paid key, every series and all history.
