corpus-cloud-pricing-mcp
MCP server (stdio) for corpusAI Cloud Pricing: AWS, GCP and Azure spot price history at event resolution, on-demand and reserved list prices, GPU rental quotes from neo-clouds and marketplaces, LLM token prices, and daily index fixings per GPU and segment (CX.H100SXM.NEO, CX.H100SXM.SPOT, ...). Free tools need nothing. Paid tools pay per call in USDC over x402 through Circle Gateway, from a wallet you configure.
The API also takes MPP (USDC on Tempo) and prepaid keys. To use a prepaid key from an agent, connect to the hosted MCP server at https://cloud.trycorpus.ai/mcp instead of this package (see the docs).
Install
Claude Code:
claude mcp add corpus-cloud-pricing -e CORPUS_PAYER_KEY=0x... -- npx -y corpus-cloud-pricing-mcp
Claude Desktop, Cursor or any MCP client (mcp.json):
{
"mcpServers": {
"corpus-cloud-pricing": {
"command": "npx",
"args": ["-y", "corpus-cloud-pricing-mcp"],
"env": { "CORPUS_PAYER_KEY": "0x...", "CORPUS_CHAIN": "base", "CORPUS_MAX_USDC": "0.10" }
}
}
}
Without CORPUS_PAYER_KEY the free tools work and the paid tools return the price and accepted networks instead of data.
Paying
Paid calls are settled gaslessly from a Circle Gateway USDC balance held by the payer wallet. Fund it once:
CORPUS_PAYER_KEY=0x... npx corpus-cloud-pricing-mcp balance
CORPUS_PAYER_KEY=0x... CORPUS_CHAIN=base npx corpus-cloud-pricing-mcp deposit 2.00 # needs USDC and a little gas on that chain
CORPUS_CHAIN takes a Circle Gateway chain name as the Gateway SDK spells it (base, ethereum, arbitrum, worldChain, hyperEvm, ...). CORPUS_MAX_USDC (default 0.10) refuses any single call priced above it. Prices: 0.01 USDC for single-type or single-fixing calls, 0.05 for full histories, 0.10 for region or market snapshots.
Tools
Free: catalog, instances, gpu_models, index_tickers, status, tokens_models.
Paid: spot_daily, spot_hourly, spot_events, spot_latest, spot_snapshot, spot_monthly, ondemand, reserved, gpu_quotes, gpu_index, index_fixing, index_history, index_board, term_instance, term_curve, tokens_quotes, tokens_fixing, tokens_history, tokens_board, capacity_stress, capacity_history, capacity_board.
The hosted server generates its tools from the OpenAPI document, so its set is larger and a few names differ (its GPU term structure tool is term, where this package says term_curve).
