"""DC Hub — Power Index demo + MCP server (Hugging Face Space).

A live demo of the DC Hub Power Index (DCPI) that ALSO runs as an MCP server
(launch(mcp_server=True)) so Hugging Face Agents / smolagents and any MCP client
can query it. Seven tools: the two DCPI classics (dcpi_score, compare_markets)
plus five bridge tools (grid scoreboard, facility search, market ranking,
interconnection queue, hyperscaler deals) forwarded to DC Hub's canonical MCP
server. The complete DC Hub MCP — every facility, market and deal in the
index, plus real-time grid telemetry, fiber and gas — lives at
https://dchub.cloud/mcp. Connect that for the full dataset (10 calls/day free
anonymous; free key via its claim_free_key tool).

★ COUNTS ARE NOT TYPED IN THIS FILE. They resolve from DC Hub's canon endpoint
  (/api/v1/canon/phrases) via _canon() below, because a typed count here rots
  silently: this Space shipped a facilities figure ABOVE canon's citation-safe
  floor — an OVER-claim, the one direction a floored count must never take. Docstrings are the exception and state no count at all: they are
  the MCP tool schema, they are read once at import, and a network call in the
  import path is its own defect.

Optional Space secret DCHUB_API_KEY (a dchub_ key) lifts the bridge tools to
full-tier responses; without it they ride the anonymous free tier.

UI NOTE: the 7 tool functions below are the MCP contract (names + docstrings
become the tool schema at /gradio_api/mcp/schema) — keep them stable. UI-only
events that reuse them (e.g. textbox .submit) pass api_name=False so they
never mint a duplicate MCP tool.
