Store API — MCP server

One MCP endpoint that gives your AI client access to GPT, Claude, Gemini, DeepSeek, Grok, Qwen and GLM through a single API key. Ask another model from inside your current chat, generate images, check your balance — without leaving Cursor, Claude Desktop or Claude Code.

Built for developers in Russia: payment with locally issued cards, no VPN required, prices in rubles, pay per token with no subscription.

Endpoint: https://store-api.com/mcp (Streamable HTTP)
Auth: Authorization: Bearer sk-shop-…, or ?key=sk-shop-… in the URL for clients that cannot send headers
Get a key: https://store-api.com/login — free account, pay only for what you use

Tools

Tool	What it does
`ask_model`	Ask any model from the catalog and get the answer back as text. Sitting in Claude, ask GPT-6 or Gemini — and the other way around.
`list_models`	Catalog with prices in rubles per 1M tokens, optionally filtered by provider.
`generate_image`	Generate an image from a prompt, returns a link.
`balance`	Remaining funds on your key.

Setup

Cursor

~/.cursor/mcp.json:

config.json

{
  "mcpServers": {
    "store-api": {
      "url": "https://store-api.com/mcp",
      "headers": {
        "Authorization": "Bearer sk-shop-YOUR_KEY"
      }
    }
  }
}

Claude Desktop and other clients without header support

Pass the key in the URL:

config.json

{
  "mcpServers": {
    "store-api": {
      "url": "https://store-api.com/mcp?key=sk-shop-YOUR_KEY"
    }
  }
}

A header is safer than a query string — a URL may end up in client logs. Keys can be revoked and reissued at any time in the dashboard.

Claude Code

Terminal

claude mcp add --transport http store-api "https://store-api.com/mcp?key=sk-shop-YOUR_KEY"

Check that it works

Ask your assistant: "show my Store API balance". If it answers with an amount, you are connected. Then try "ask GPT-6 Sol what it thinks about this code".

Pricing

Same as regular API calls: you pay for the tokens of the model you invoked, at the catalog price. There is no extra charge for the MCP server itself and no subscription. Current prices: https://store-api.com/#plans

Models

OpenAI (GPT-6, GPT-5 family, GPT-4o), Anthropic (Claude Opus, Fable, Sonnet, Haiku), Google (Gemini), DeepSeek, xAI (Grok), Qwen, Z.ai (GLM), plus image models. The full list with prices is returned by list_models.
