SpotGPU

Discontinued Oct 2026: the SpotGPU API has been shut down. This package no longer works.

spotgpu-mcp

MCP (Model Context Protocol) server for SpotGPU spot GPU rental prices.

Exposes one tool: spot_price → GET /v1/spot (Vast + RunPod best + alts).

Credits ≠ rental. SpotGPU API credits pay for price lookups.
usd_per_hr is the upstream provider rental price, not a SpotGPU fee.

Install / run

Requires Python 3.10+ and a SpotGPU API key.

Get an API key (free trial, 25 credits)

curl -X POST https://spotgpu-api.fly.dev/v1/keys

No auth, no email. The response contains api_key (shown once — store it) with 25 trial credits (1 credit per successful lookup). Limit: 3 keys per IP per 24h. Put it in SPOTGPU_API_KEY in your MCP client config. Check your balance:

curl -H "Authorization: Bearer $SPOTGPU_API_KEY" https://spotgpu-api.fly.dev/v1/account

Out of credits (HTTP 402)

When credits run out the API returns 402 insufficient_credits and the tool error points to the top-up page. Buy a credit pack ($5 / 500, $10 / 1000, $50 / 5000) at https://spotgpu-api.fly.dev/topup, or POST /v1/checkout with {"pack_id": "credits_500"} and your Bearer key to get a Stripe Checkout URL. A 401 tool error includes the signup curl above.

One-shot (PyPI)

uvx spotgpu-mcp

Local (this monorepo package)

cd packages/mcp-spotgpu
uv sync   # or: pip install -e .
export SPOTGPU_API_KEY=sk_…
spotgpu-mcp

Env:

Variable	Required	Default
SPOTGPU_API_KEY	yes	—
SPOTGPU_BASE_URL	no	https://spotgpu-api.fly.dev

Never hardcode keys. The server speaks MCP on stdio only (do not print to stdout).

Claude Desktop

Add to claude_desktop_config.json:

{
  "mcpServers": {
    "spotgpu": {
      "command": "uvx",
      "args": ["spotgpu-mcp"],
      "env": {
        "SPOTGPU_API_KEY": "sk_…"
      }
    }
  }
}

Local editable install instead of uvx:

{
  "mcpServers": {
    "spotgpu": {
      "command": "uv",
      "args": ["run", "--directory", "/path/to/spotgpu/packages/mcp-spotgpu", "spotgpu-mcp"],
      "env": {
        "SPOTGPU_API_KEY": "sk_…"
      }
    }
  }
}

Cursor

Add to .cursor/mcp.json (or user MCP config):

{
  "mcpServers": {
    "spotgpu": {
      "command": "uvx",
      "args": ["spotgpu-mcp"],
      "env": {
        "SPOTGPU_API_KEY": "sk_…"
      }
    }
  }
}

Tool: spot_price

Param	Type	Default	Notes
gpu	string	required	e.g. RTX_4090
qty	int	1	≥ 1
markets	string	"vast,runpod"	comma-separated
fresh	bool	false	maps to fresh=1

On success returns JSON text of the API body (best.usd_per_hr, alts, …).
