Compare MCP servers by category, or browse hosted MCP servers if you prefer an endpoint over a local process.
Check the linked publisher documentation and your connected client's tool list. Names and availability can vary with the server version and account permissions.
| Tool | What it does |
|---|---|
| openaq_find_locations | Find monitoring stations near a point, in a bounding box, or by country. The required first step — readings and measurements key on the location id this returns. |
| openaq_get_readings | Latest measured value for every sensor at a station, each joined with its pollutant and unit. The current-conditions tool. |
| openaq_get_measurements | Historical series for one pollutant at one station over a date range, with raw/hourly/daily aggregation. Large ranges spill to a DataCanvas. |
| openaq_list_parameters | Catalog of measurable pollutants and their canonical units. The unit-disambiguation reference. |
| openaq_list_countries | Catalog of country-level coverage — data span and parameters measured, filterable by parametersId to answer "which countries measure this pollutant?". An availability check before a regional sweep. |
| openaq_dataframe_describe | List the tables and columns staged on a DataCanvas so you can write valid SQL. |
| openaq_dataframe_query | Run a read-only SELECT over staged measurement series. |
