Overview

AI-generated overview

A discontinued MCP server that looked up spot GPU rental prices from Vast and RunPod through the SpotGPU API.

What you can do
  • Look up spot GPU rental prices across Vast and RunPod, returning the best offer and alternatives as JSON.
  • Filter a lookup by GPU model, quantity, market list and a fresh-price flag.
  • Report the upstream provider's hourly rental price per offer.
  • Note: the README states the SpotGPU API was shut down in October 2026 and the package no longer works.
When to use it
Only of historical interest: the README says the backing API is shut down and the package no longer works, so it is not worth installing for current price lookups.
Requirements
Python 3.10+ and a SpotGPU API key in SPOTGPU_API_KEY; optional SPOTGPU_BASE_URL overrides the API base URL. Runs locally over stdio, typically via uvx. The API it depends on is reported as shut down.
Before you install
The API key is a secret and must not be hardcoded; it is shown only once at signup. Lookups consume paid credits, and running out returns HTTP 402 with a top-up path that involves buying credit packs through Stripe checkout. Requests send an X-SpotGPU-Client attribution header. The service is reported as discontinued, so the key and credits may be unusable.

Installation

In SourceWeft

  1. Open SpotGPU in the dashboard and add it to a workspace.
  2. Enable the server for the chats that should use its tools.

Desktop only via STDIO. STDIO servers start a local process, so they need the SourceWeft desktop host.

Other MCP clients

Follow the launch instructions in the repository.

README

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)

bash
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:

bash
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)

bash
uvx spotgpu-mcp

Local (this monorepo package)

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

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

Local editable install instead of uvx:

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

json
