DC Hub is the live data layer for data-center site selection and the power, grid and energy infrastructure behind it. Its DCPI is a daily score of where data centers can get grid power, across 300+ markets. Agents can query it and cite it. It also covers 330,000+ mapped power, grid, gas and fiber assets and ISO interconnection queue snapshots, and carries live grid feeds from the seven US ISOs (PJM, ERCOT, CAISO, MISO, SPP, NYISO, ISO-NE), plus retail and wholesale electricity prices by state and ISO. Answers carry an as-of timestamp and a citation line. The server has 94 MCP tools at https://dchub.cloud/mcp plus a REST API at https://dchub.cloud/api/v1. The free tier needs no key; paid plans: dchub.cloud/pricing. Capacity Source adds a free capacity marketplace: operators list data-center capacity at https://dchub.cloud/listings, and agents search it by size and location with sourcecapacity, then request an introduction with requestcapacity_intro.
Synci connects your real bank, brokerage, and crypto-exchange accounts to AI assistants, read-only. Ask about balances, transactions, holdings, and spending across all your accounts in one place: "What did I spend on groceries last month?" "Which subscriptions am I paying for, and what do they cost per year?" "How is my portfolio allocated across stocks, ETFs, and crypto?" "Compare my checking account balance today with the start of the month." "Are any of my bank connections failing?"
