Coordination event bus connecting MCP servers for East Africa — drought alerts, health cascades, agricultural advisories. The missing layer between 31 isolated tools. # africa-coord-bus **The coordination layer between East Africa's AI tools.** 31 MCP servers exist for Kenya's coordination domains — payments, water, agriculture, health, land, education. They work in isolation. When `wapimaji-mcp` detects a drought six weeks in advance, `bima-mcp` doesn't know to evaluate parametric insurance payouts. `afya-mcp` doesn't know to activate malnutrition surveillance. `kilimo-mcp` doesn't know to issue drought-resistant crop advisories. This package provides the event bus that connects them. ## The coordination gap A smallholder farmer in Turkana has parametric crop insurance. NDVI anomaly data shows drought coming 6 weeks out. The insurance contract says coverage triggers when SPI drops below -1.5. Without coordination: the farmer finds out the crop is failing at harvest. The insurance company finds out at claims submission. The health system finds out at clinic presentation. With coordination: ``` wapimaji-mcp → CoordinationEvent(drought_alert, ALERT) │ ├── bima-mcp.evaluate_parametric_payout (triggered immediately) ├── kilimo-mcp.issue_drought_advisory (farmers receive SMS) ├── afya-mcp.activate_malnutrition_watch (CHWs briefed) └── county-mcp.alert_county_health (county notified) ``` Six weeks earlier. Before the damage is visible. ## AI Agent Compatibility Model-agnostic. Tested with: | Model | Notes | |-------|-------| | `claude-sonnet-5` | **Recommended** — completes drought→insurance→county cascades end-to-end | | `claude-opus-4-8` | Highest accuracy for complex multi-domain triage | | `gemini-flash` | High-volume, cost-sensitive routing | Sonnet 5 (2026-06-30) is the first Sonnet-class model that reliably finishes the full multi-server cascade without stopping mid-chain. ## Architecture: Shared Context Store (CA-MCP) **Research validation:** *Enhancing MCP with Context-Aware Server Collaboration* (arXiv:2601.11595, January 2026) — introduces **CA-MCP**, adding a Shared Context Stor …
