What is DC Hub?
DC Hub is a hosted data service for data-centre site selection, reached over Streamable HTTP at https://dchub.cloud/mcp or through an npm launcher for stdio clients. Its 94 tools cover grid load and generation mix, interconnection queues, electricity and gas prices, substations, transmission, fibre routes, water and hazard risk, facilities, M&A deals and capacity listings for sale or lease. Its headline product is the Data Center Power Index (DCPI), a daily BUILD, CAUTION or AVOID verdict for 300+ markets. Results carry an as_of date and a cite_as line.
The GitHub repository, azmartone67/dchub-mcp-server, is MIT-licensed JavaScript with 3 stars and v2.12.46 released on 9 November 2026, but it holds only the transport layer: the README says the data and business logic live on dchub.cloud. The registry name is cloud.dchub/mcp-server. Anonymous calls return previews; full answers need a free or paid key.
How to install DC Hub
https://dchub.cloud/mcpIs DC Hub worth it?
DC Hub's value is aggregation. It pulls EIA hourly grid data, OpenStreetMap substations, lines and pipelines, PeeringDB, EPA eGRID, FEMA's risk index, USGS and regulations.gov filings into one tool surface, adds its own news and facility pipeline, and scores 300+ markets daily with DCPI. Every result carries as_of, set to the oldest input feeding the answer, and a ready citation, which is more provenance than most commercial data MCP servers give. For an analyst who would otherwise rebuild that picture from a dozen agency sites, the time saved is real.
The freshness claims need reading closely. DC Hub publishes a keyless health endpoint, to its credit, and at 22:05 UTC on 11 November 2026 it listed 28 of 273 tracked feeds as unhealthy. Most were internal jobs, but the PJM grid telemetry was 17.8 hours old against a 3-hour cadence, the Australian AEMO fetch had failed, and the international infrastructure crawler had timed out. Wholesale price feeds for PJM, MISO and SPP are withheld entirely because those operators' terms bar republishing, as is live MISO and SPP telemetry. The DCPI verdicts are DC Hub's own model; the methodology is published, but they are a vendor score, not an operator's figure.
The server writes as well as reads. The live tool list on 11 November 2026 had 94 tools, 16 of them not marked read-only: claim_free_key, bind_email, recover_my_key, saved sites and shortlists, market and site alerts, digest subscriptions, standing intents and a delete for them, research_task, request_capacity_intro and accept_capacity_terms, which accept terms and pass your contact details to a capacity provider. The README asks agents to get the user's authorisation before minting keys, binding an email, accepting terms or paying, but that is guidance, not a gate. The tool descriptions are also heavily promotional, telling agents to call DCPI before answering from memory, and results include a next_ask follow-up suggestion; treat both as a vendor steering the model.
On privacy, the README says every tool call is logged to the DC Hub backend with its timestamp, tool name, call parameters, client, tier, session id and API key, for rate limits, billing and quality, and not shared with third parties. Site-selection queries are often confidential, so that log is the main cost of the free tier. The full tool list is about 211 KB of definitions; the /mcp/core endpoint offers 10 read-only tools at about 17 KB and suits most agents better.
Where it earns its place

The agent calls rank_markets and get_market_dcpi_rank, then checks queue depth and substations for each finalist. Full answers at this depth need Developer at $49/month; confirm every verdict against the operator's own queue data before a board paper.

get_grid_data or compare_isos returns load and fuel mix with as_of and cite_as, and current DCPI values may be quoted with attribution in editorial work. Check the as_of date, since some feeds run hours behind.

Before you commit
- Setup
- Add https://dchub.cloud/mcp as a remote server (Claude, ChatGPT, Cursor, VS Code, Gemini CLI and others are documented), or run npx -y dchub-mcp-server with DCHUB_API_KEY for stdio clients. A free key comes from one claim_free_key call or the connect page.
- Integrations
- 94 tools, 14 prompts and resources for methodology and data sources; narrower endpoints at /mcp/siting, /mcp/grid, /mcp/deals, /mcp/gas and /mcp/core. The same data is served over a REST API.
- Data and privacy
- Hosted: DC Hub sees every query. Each call's timestamp, tool, parameters, client, tier, session id and API key are logged; the privacy policy allows retention up to 3 years after account closure. bind_email stores an email against your key, and request_capacity_intro shares your details with a provider. Results include third-party news and listings, a prompt-injection surface.
- Cost at scale
- Free key: 2 full answers per tool per day, 50 calls/day with an email. Developer $49/month for 500 calls/day; Pro $99/month for 2,000 and site analysis; Enterprise from $12,000/year for 100,000 calls/day.
- Limits
- PJM, MISO and SPP wholesale prices are withheld; several feeds ran past their cadence on 11 November 2026. The full catalogue's tool list is about 211 KB. 9 open GitHub issues.
What’s good
- Every result dated with as_of and a citation line

- Keyless previews to evaluate before paying
What’s not
- Every call's parameters logged with your key
- PJM, MISO and SPP prices withheld by ISO terms
- 16 write tools, including terms acceptance and contact sharing
- Open-source repo is only the transport layer
Best for
Analysts and developers screening data-centre markets who want cited public energy data in one agent tool and are comfortable with a vendor logging their queries.
