GrabGPU MCP server

Find a cloud GPU you can actually rent. GrabGPU checks 22 GPU clouds every day (RunPod, Vast.ai, Lium, the providers behind Shadeform and more) and records, for 71 GPU models, the price per GPU hour and whether the provider reports it in stock.

This repository documents the hosted MCP server. There is nothing to install or run: the server is remote.

The tool

find_gpu returns offers from the latest daily snapshot. Rentable offers come first, then cheapest.

Argument	Type	Meaning
`gpu`	string	GPU model, e.g. `H100`, `B300`, `RTX 4090`. Omit for every model.
`in_stock`	boolean	Default `true`: only offers in stock. `false`: also offers out of stock or with unknown stock.
`min_gpus`	integer	Smallest node size, e.g. `8` for an 8x node.
`max_price`	number	Highest USD per GPU hour.
`limit`	integer	How many offers, default 20, at most 100.

Each offer has gpu_name, provider_name, usd_per_gpu_hour, availability (in_stock, unknown, out_of_stock), max_gpus, rent_url, direct_url and is_referral.

Example prompts:

"Where can I rent an H100 right now, and what is the cheapest in-stock offer?"
"I need an 8x H100 node. Who has one in stock?"
"Show me every GPU in stock under $1 an hour."

Check it from a terminal:

curl -s https://grabgpu.com/mcp -H 'content-type: application/json' \
  -d '{"jsonrpc":"2.0","id":1,"method":"tools/call","params":{"name":"find_gpu","arguments":{"gpu":"H100","limit":3}}}'

Referral links and privacy

Some rent_url links are provider referral links: the provider may pay GrabGPU a commission, the price for you does not change, and the order is always by stock and price, never by commission. Each offer says whether its link is a referral (is_referral).
