Settings → Connectors → Custom connector → Remote → URL https://api.exascale.build/mcp → Authentication: Open → Add.

Or call REST directly

# discover what's available
curl https://api.exascale.build/v1/capabilities

# top 5 states by operating power capacity, cited
curl -X POST https://api.exascale.build/v1/power/capacity/query \
  -H 'content-type: application/json' \
  -d '{"group_by":["state"],"order_by":"nameplate_mw","top_n":5}'

# prove any returned value back to its raw source cell
curl -X POST https://api.exascale.build/v1/evidence/source-row \
  -H 'content-type: application/json' -d '{ ...the row's verify handle... }'

What you get

• Cited, verifiable answers — every value carries its source, as_of, and a handle that resolves to the raw cell with a matching SHA-256.
• Agent-first — discover → describe → query → verify; the tools tell your agent exactly how to call them.
• Live now — US power: capacity (EIA-860M), generation (EIA-923), demand (EIA-930), retail sales (EIA-861), capacity factor. AI infra · Space · Robotics packs rolling out.
