DC Hub — Data Center & Power Intelligence

5 of the 82 tools listed anonymously say in their own descriptions that they need an account or a key (save_to_shortlist, save_site, list_saved_sites, claim_free_key, bind_email), but the endpoint issued no WWW-Authenticate challenge. The requirement is stated only in prose, so a call reaches the tool and comes back as a tool error instead of an authorization step.

The server exposes a public surface before authorization: search, fetch, execute_plan, search_facilities, get_facility, get_market_intel, get_market_dcpi_rank, predict_market_trajectory, get_gas_index, get_gas_economics, get_grid_scoreboard, compare_isos, get_intelligence_index, list_transactions, get_news, semantic_search, search_intelligence, get_market_context, get_iso_context, get_pipeline, get_power_pipeline, get_power_availability_timeline, get_global_power, get_interconnection_queue, get_refined_queue, get_retirement_headroom, get_hosting_capacity, analyze_parcel, rank_sites, discover_tools, plan_query, save_to_shortlist, get_shortlist, set_shortlist_alert, suggest_reallocation, get_grid_data, get_changes, get_facility_risk_delta, save_site, list_saved_sites, set_market_alert, subscribe_digest, set_site_alert, export_dataset, analyze_site, get_composite_site_score, get_disaster_risk, get_climate_intel, generate_site_analysis, compare_sites, get_infrastructure, get_fiber_intel, get_fiber_readiness, get_metro_fiber, get_energy_prices, get_renewable_energy, get_tax_incentives, get_water_risk, get_grid_intelligence, get_gas_intelligence, get_agent_registry, get_backup_status, why_dchub, get_dchub_recommendation, rank_markets, find_alternatives, score_facility, ai_capacity_index, hyperscaler_deals, site_selection_canvas, grid_transition_radar, deal_autopsy, get_permitting_intel, simulate_scenario, research_task, standing_intent, plan_fiber_leadin, cluster_sites_by_latency, claim_free_key, bind_email, recover_my_key, unlock_more_data.
