rentgpu GPU Market MCP
Live endpoint: https://rentgpu.link/mcp — a read-only MCP server exposing real-time GPU
rental price data, monetized per call with x402 (USDC on Base mainnet).
No signup, no API key, no credit card — the payment proof is the identity.

Data coverage
- 26 platforms (11 of them China-based: AutoDL, 恒源云/gpushare, 矩池云, 优云智算, 算家云, 晨涧云 …), 23 GPU models (RTX 3090/4090/5090 → A100/H100/H200/B200/L40S/MI300X), ~110 live quotes.
- Re-crawled every 45 minutes from public price pages / public APIs.
- Ranked strictly by price. No paid placement. Reference-price entries are flagged and excluded from "lowest price" ranking.
- Prices are CNY per GPU per hour (USD×7.2). Multi-GPU machines are normalized to per-GPU price.

Quick start (this repo)
python -m venv venv && source venv/bin/activate # Windows: venv\Scripts\activate
pip install -r requirements.txt
python server.py # stdio MCP server on the bundled sample data
Point an MCP client at it:
{ "mcpServers": { "rentgpu-gpu-market": { "command": "python", "args": ["server.py"] } } }
Or talk to the live hosted endpoint (streamable HTTP, x402-paid):
{ "mcpServers": { "rentgpu-gpu-market": { "url": "https://rentgpu.link/mcp" } } }
A minimal x402-paying demo client is in client_agent.py (set BUYER_KEY env var to a funded
Base USDC wallet; do not commit keys).

MARKET_JSON |
./data/market.json (bundled sample) |
path to the market data file |
The bundled data/market.json is a static sample. The hosted service regenerates it every
45 minutes; self-hosters can wire the same generator against their own crawl.
Design principles
- Strictly read-only — tools only query the market file; no writes, no DB.
- Discovery is free —
list_gpu_models/pingcost nothing (an agent can't buy what it can't see). - Failed delivery is never charged — if a tool errors, the x402 wrapper does not settle.
