Intelligence Systems

Tension Index Algorithm -- Composite 0-100 score computed from 4 weighted components: conflict (ACLED events + fatalities), disasters (earthquakes + fires + GDACS), sentiment (GDELT tone analysis), instability (cyber threats + GPS jamming + predictions). 7-day rolling history.

Geo-Correlation Engine -- Multi-signal event detection across all active layers. Earthquake clusters, fire convergence zones, negative news surges, and cross-domain anomalies detected in real-time using geospatial proximity matching.

Country Intelligence Index -- 23 nations scored 0-100 across events, disasters, sentiment, and predictions. Per-country component breakdown with historical trend detection. Severity classification: LOW / MODERATE / ELEVATED / CRITICAL.

Personal Intel Engine -- User-defined watchlists scan all incoming data for keyword and country matches. AI-generated personalized morning briefs via Claude Haiku. Browser notification alerts with configurable thresholds.

AI Command Center

AI Terminal -- Full command-line interface at nexuswatch>. Query any layer, generate situation reports, filter by region or threat type, and issue natural language commands against live intelligence data.

Auto-Threat Detection -- Continuous scanning across all 30 layers for anomalous patterns. Automatic alert generation when multi-signal events converge or thresholds are breached.

Contextual Narration -- AI-generated situation reports synthesizing active layer data into human-readable intelligence briefs on demand.

MCP Server (AI Agent Access)

NexusWatch exposes a Model Context Protocol server for AI agents. Query country risk scores, run geopolitical scenarios, analyze portfolio exposure, and more — directly from Claude, GPT, or any MCP-compatible client.

Quick Start (Claude Code)

claude mcp add --transport http nexus-watch https://nexuswatch.dev/api/mcp \
  --header "X-API-Key: nwk_pub_02e13b5a7ff73aed53e2ceb5"

Public key: nwk_pub_02e13b5a7ff73aed53e2ceb5 (100 calls/hour, no signup required).

Then ask: "What's the instability score for Taiwan?" or "Run the Hormuz closure scenario."

Available Tools

Tool	Description
get_country_risk	CII score (0-100) with 6 components for any of 86 countries
get_alerts	Active threshold breaches, 7-day movers, crisis triggers
run_scenario	7 preset what-if simulations with cascade chains
get_portfolio_exposure	Map holdings to geopolitical risk + chokepoint deps
get_risk_factors	Z-scores, momentum, realized vol for quant strategies
get_audit_trail	Full computation history with evidence chains
get_active_crises	Live crisis triggers (CII spikes, M7+ quakes)
get_sanctions_attribution	OFAC/UN sanctions cross-referenced with conflicts
validate_predictions	Prediction accuracy: predicted vs actual CII
