who

who_get_indicator_metadata

Fetch metadata for one or more WHO GHO indicator codes: the full indicator name and the dimensions it supports (e.g. COUNTRY, REGION, SEX, YEAR, WORLDBANKINCOMEGROUP, AGEGROUP). Call this before querying data with who_query_indicator_data to confirm which filter dimensions are valid for a given indicator. Accepts up to 10 codes per call. Codes with no metadata are reported in the notFound array rather than causing an error.

who_list_dimension_values

List valid codes and labels for a WHO GHO dimension type such as COUNTRY, REGION, SEX, WORLDBANKINCOMEGROUP, or AGEGROUP. Use this to discover valid filter values before calling who_query_indicator_data, or to confirm the correct ISO code for a country. Use who_list_dimensions to discover all available dimension type codes.

who_list_dimensions

List all dimension type codes and human-readable titles available in the WHO Global Health Observatory API. Use this to discover valid dimension codes before calling who_list_dimension_values. Common dimensions include COUNTRY, REGION, SEX, WORLDBANKINCOMEGROUP, and AGEGROUP, but many additional types exist — this tool exposes them all.

who_list_indicators

Browse the WHO Global Health Observatory indicator catalog with pagination. Use when you want to explore indicators without a keyword, or to page through the full catalog. Use who_search_indicators when you have a keyword to narrow the results.

who_query_indicator_data

Query data rows for a single WHO GHO indicator with optional spatial, temporal, and dimension filters. Returns rows with numeric values, uncertainty intervals (Low/High), and spatial/time metadata. This is the primary data-fetching tool in the find-then-query workflow: use who_search_indicators to find the indicator code, optionally call who_get_indicator_metadata to confirm which filter dimensions are valid, then call this tool. Spatial filters are mutually exclusive per call: provide only one of country_codes, region_codes, or income_group_codes — mixing them triggers an error. Omitting all spatial filters returns all geographies (may be large; use limit to cap). The sex filter only applies when the indicator uses SEX as its first cross-cutting dimension — if not, the filter returns empty rows; check who_get_indicator_metadata first if uncertain.

who_search_indicators

Search the WHO Global Health Observatory indicator catalog by keyword in the indicator name. Returns indicator codes and names for use with who_query_indicator_data. The search uses a substring match on indicator names — try terms like "life expectancy", "immunization", "mortality", "diabetes", or "HIV". If results are truncated, refine the query or use who_list_indicators to browse by offset.

Who Gho MCP Server — questions

Answers built from our own checks of this server.

What can Who Gho MCP Server do?

It exposes 6 tools, read directly from the server on our last check. Among them: who_get_indicator_metadata, who_list_dimensions, who_list_dimension_values, who_list_indicators, who_query_indicator_data, who_search_indicators. The full list with descriptions is on this page — we take it from the server itself via tools/list, not from a README. How MCP servers expose tools in the first place →

Is Who Gho MCP Server working right now?

We send a real MCP handshake every 15 minutes. Over the last 24 hours 91 of 91 checks got a reply (100.0%), average response time 399 ms. The bar chart above shows every period we have measured.

How do I connect Who Gho MCP Server?

Copy the ready config from this page — we generate it for Claude Code, Claude Desktop, Codex, Cursor and VS Code, each with the file path that client actually reads. It is a remote server, so there is nothing to install — the client connects to the address.

Does Who Gho MCP Server need an API key?

No. Who Gho MCP Server completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 6 of them are readable on this page. This is what we observed, not what the docs claim.

How fast is Who Gho MCP Server?

It answers our handshake in 399 ms on average, which is faster than 34% of all working MCP servers we measure. The comparison comes from our own checks across the whole registry, every 15 minutes.

How many people use Who Gho MCP Server?

The npm package @cyanheads/who-gho-mcp-server was installed 82 times in the last week. Week over week that is -23%. We show installs rather than GitHub stars on purpose: a star is a bookmark, an install is someone actually running it.
