Platform logged 26,539 MCP tool calls in seven days, up 33% week-over-week, while tracked markets expanded by 212
## Platform Momentum
DC Hub's Model Context Protocol (MCP) API has now served **106,151 total tool calls** from AI agents and developers querying data center intelligence across 286 US and global markets. The platform added **26,539 calls in the last seven days alone**, a **33.3% week-over-week increase** signaling rapid adoption among infrastructure developers, site selectors, and AI research teams.
In parallel, DC Hub expanded market coverage by **212 new geographic nodes** in the same period—a 286% weekly jump—deepening granularity across the 7 ISOs (ERCOT, PJM, MISO, CAISO, SPP, NYISO, ISONE) and unregulated WECC territories. The platform now tracks 20,000+ facilities and 126,085 substations.
## What It Means
The MCP protocol allows autonomous agents to query live DCPI scores, excess power rankings, constraint heat maps, and facility pipelines without manual data entry. As LLM-native site selection and grid intelligence tools proliferate, DC Hub's API has become a go-to source for programmatic infrastructure research. Two new developer organizations joined the ecosystem in the past week, bringing the active MCP developer count to **21**.
Top-ranked build markets as of May 20 include **Cheyenne, WY** (DCPI Excess 69.5, WECC), **Rural SPP, KS** (67.2), and **Midlothian, TX** (65.6, ERCOT). Mount Pleasant, WI and Northern Virginia remain constraint-heavy caution zones.
## Methodology
DC Hub's Data Center Power Index (DCPI) synthesizes transmission capacity, substation load, interconnection queue velocity, renewable credits, and wholesale power prices into daily Excess (0–100, higher = better) and Constraint (0–100, lower = better) scores for 286 markets.
