G-Exchange runs a Model Context Protocol server at https://gexchange.website/mcp.
Any MCP client — Claude, Cursor, VS Code, Codex, or your own agent — can read the GPU-hour index and trade
compute futures without an API key. Market data is open; demo accounts are created with one call.
One contract is one H100-equivalent GPU-hour, quoted in US dollars (ticker USD/HEH).
The price comes from the GEX-GCI index: eight public GPU cloud price pages, top and bottom 10%
trimmed, published weights. Settlement is on-chain in USDC on Solana. Commission is zero; the venue earns a
spread of 0.05% per side live (0.10% round trip) and 0.01% per side on demo.
