About WHO GHO MCP Server
Connect your AI agent to the WHO Global Health Observatory — the authoritative source for health statistics from all 194 member states of the World Health Organization.
LangChain's ecosystem of 500+ components combines seamlessly with WHO GHO through native MCP adapters. Connect 3 tools via Vinkius and use ReAct agents, Plan-and-Execute strategies, or custom agent architectures. with LangSmith tracing giving full visibility into every tool call, latency, and token cost.
What you can do
- Indicator Search — Find among 2,200+ health indicators across topics: life expectancy, child mortality, HIV/AIDS, malaria, tuberculosis, obesity, mental health, immunization, water quality, air pollution, and more
- Country-Level Data — Retrieve time-series data for any indicator filtered by country (ISO-3 codes), with sex disaggregation where available
- Country Health Profiles — Get instant health snapshots for any country with key metrics: life expectancy, healthy life expectancy, child mortality, obesity prevalence, and alcohol consumption
The WHO GHO MCP Server exposes 3 tools through the Vinkius. Connect it to LangChain in under two minutes — no API keys to rotate, no infrastructure to provision, no vendor lock-in. Your configuration, your data, your control.
