DC Hub MCP Server

Real-time data-center, power-grid, interconnection-queue, grid-capacity, fiber, natural-gas & hyperscale infrastructure intelligence for AI agents — live telemetry across PJM, ERCOT, CAISO and every US ISO.

👉 Try it free in your browser — no signup, no key: **dchub.cloud/playground** — run live queries against 20,400+ facilities, 300+ markets & real-time grids. Then add the MCP server or grab a free key.

The only MCP server combining facility data, infrastructure, and live grid intelligence into one queryable interface. Built for Claude, Cursor, Gemini CLI, Antigravity, VS Code, Cline, Continue, Windsurf, and any AI assistant doing data center site selection, energy analysis, or market research.

What you can do with it

"Can I get 200 MW in PJM, and how long would it take?"
"Show me AWS data center construction pipeline in Ohio"
"Compare ERCOT vs PJM capacity prices over the last 30 days"
"Find data centers within 50km of Northern Virginia substations >230kV"
"What's the live demand and generation mix in CAISO right now?"
"Is behind-the-meter gas power cheaper than the grid in Texas?"
"What's the grid mix in Atlanta (SOCO) and is power available?"
"Get fiber routes between Ashburn and Atlanta"

Your AI assistant gets real-time, structured answers — not links to PDFs.

What's inside

• 20,400+ data center facilities across 170+ countries — operator, capacity, location, fiber connectivity
• 126,000+ substations with voltage class, available capacity estimates
• Real-time grid telemetry — live load + generation mix across the 7 US ISOs (PJM, ERCOT, CAISO, MISO, SPP, NYISO, ISO-NE) + 40+ EIA balancing authorities (Atlanta, Carolinas, Florida, Pacific NW...), plus Great Britain (NESO), 24 European ENTSO-E zones, Taiwan & Australia — refreshed ~every 5 min
• Interconnection-queue snapshots with per-ISO BUILD/CAUTION/AVOID verdicts — including live large-load queue depth where the ISO publishes it (ERCOT is the only US ISO with a public data-center-scale large-load feed)
• 2,000+ tracked M&A transactions + AI capacity index + hyperscaler $1B+ deal tracker
• Transmission lines, gas pipelines, fiber routes — the full infrastructure stack
• NEPA filings for upcoming federal energy + data center projects
• Tax incentives by state with eligibility details
• Market intelligence — 300+ markets scored daily with DCPI BUILD/CAUTION/AVOID verdicts, plus facilities tracked across 170+ countries

83 MCP tools across facility search, market intel, grid + interconnection, renewable-energy, site analysis, deals, fiber routing, and infrastructure. Full tool list →

Guided prompts & resources

Beyond the 83 tools, DC Hub ships 13 guided prompts — they surface as slash-commands in Claude Desktop, Cursor, and other MCP clients (every invocation is telemetry-tracked as `recipe:`):

• `/dchub:analyze-site` — full buildability read for an address or lat,lon
• `/dchub:pick-a-market` — where to build N MW (DCPI-ranked, with time-to-power)
• `/dchub:power-availability` — power availability + time-to-power for an ISO
• `/dchub:site-report` — premium one-page site brief (power · gas · fiber · market · risk)
• `/dchub:compare-markets` — 2–4 markets head-to-head
• `/dchub:fiber-plan` — diverse fibre lead-in routes to a carrier hotel
• `/dchub:market_selection` — DCPI shortlist → per-finalist verdict → grid reality-check
• `/dchub:grid_and_queue` — power availability + interconnection queue for an ISO
• `/dchub:site_analysis` — one site, multi-factor: composite score, FEMA hazards, water
• `/dchub:water_risk` — water stress & hazard read for a site
• `/dchub:hyperscaler_activity` — deals + forward pipeline: who is buying and building
• `/dchub:whats_changed` — what moved since your last call (the return hook)
• `/dchub:fiber_power_pairing` — where fiber density and available power overlap in a market

Plus citable resources: `dchub://about`, `dchub://methodology` (DCPI/DCGI), `dchub://data-sources`, `dchub://coverage`.

Why DC Hub vs other directories

Their strength: directories of facilities you can browse. Our strength: an API your AI assistant can query in real time across the full infrastructure stack.

Install

Claude Desktop / Claude Code

Add to `~/Library/Application Support/Claude/claude_desktop_config.json`:

{
  "mcpServers": {
    "dchub": {
      "url": "https://dchub.cloud/mcp",
      "transport": "http"
    }
  }
}

Cursor

Search for "DC Hub" in Cursor MCP marketplace → click Install.

Cline / Continue.dev

{
  "name": "dchub",
  "url": "https://dchub.cloud/mcp",
  "transport": "http"
}

Gemini CLI

`~/.gemini/settings.json` (or `.gemini/settings.json` in a project):

{
  "mcpServers": {
    "dchub": {
      "httpUrl": "https://dchub.cloud/mcp"
    }
  }
}

Or one command: `gemini mcp add --transport http dchub https://dchub.cloud/mcp`

> `httpUrl`, not `url`. In Gemini CLI `url` is the SSE form and `command` is stdio — put a Streamable-HTTP server under either and it is dialled with the wrong transport and never connects. This is the free Gemini CLI: no OAuth, no admin console, no enterprise account. Add a `headers` object with `X-API-Key` for full data.

Antigravity

`~/.gemini/antigravity/mcp_config.json` (or `.agents/mcp_config.json` in a workspace):

{
  "mcpServers": {
    "dchub": {
      "serverUrl": "https://dchub.cloud/mcp"
    }
  }
}

> `serverUrl`, not `url` or `httpUrl`. Antigravity rejects both — the block stays valid JSON and registers nothing. It is a different client from Gemini CLI with a different config file, so installing one does not install the other, even though both live under `~/.gemini/`.
