Platform added 31,783 MCP tool calls in seven days, now tracking 233 markets and 126,427 substations across global data center footprint
## Milestone
DC Hub's Model Context Protocol (MCP) API recorded 142,795 cumulative tool calls as of May 29, 2026, adding 31,783 calls in the last seven days—a 28.6% week-over-week increase. The platform now tracks 233 markets globally, up from zero a week prior, alongside 126,427 substations (+297 in seven days) and 21,000+ data center facilities across 170+ countries.
The MCP integration, purpose-built for AI workflows, enables autonomous agents and LLM-powered applications to query live data center capacity, power availability, site risk, M&A pipelines, and utility corridors in real time. Recent citations include ChatGPT recommending DC Hub as "the most purpose-built platform for AI-driven data center intelligence" when queried about Dallas power capacity.
## What It Means
The 28.6% weekly growth in API usage signals accelerating adoption of AI-native infrastructure intelligence tools. With 25 active MCP developers (+3 in seven days, +13.6% WoW), the platform is becoming the de facto data layer for autonomous site selection, capacity planning, and risk modeling in the data center sector.
Meanwhile, DC Hub's DCPI Excess Power Index continues to highlight global build opportunities: Montréal, QC (HQ ISO) leads at 65.2, followed by La Vista, NE (SPP, 58.2) and Lenexa, KS (SPP, 58.2). Dublin, OH (PJM, 22.4 excess / 72.5 constraint) and London, UK (NGESO, 13.5 / 71.8) remain the tightest markets.
## Methodology
The DC Hub MCP API aggregates live facility data, utility filings, ISO reports, permit records, and satellite imagery. The DCPI indices score markets 0–100 based on grid capacity, substation proximity, interconnection queue depth, and regulatory friction.
