NOAA NCEI Weather Stations in an Area
ncei/find-stations
Lists NOAA GHCN-Daily weather stations inside a latitude and longitude box, with each station's id, name, coordinates, the span of its record and how complete its main elements are (temperature, precipitation, snow). Use the ids with ncei/get-station-data. Data from NOAA's National Centers for Environmental Information, GHCN-Daily, doi:10.7289/V5D21VHZ, modified by Eden Engine (fields renamed, long lists cut); not an official NOAA product.
Price
$0.0026 per call
You pay the price shown. If a call turns out to cost more than its quote, you pay the actual price, capped at twice the quote. No monthly minimum. Top-ups start at $0.50.

Use it
Five steps: search, inspect, learn, run, settle. No per-tool setup; your agent reaches this tool through the meta-tools it already has.
Connect once and your AI can find and run this tool, and any other it needs.
// 1. search: find the tool
omnial_search({ query: "what you need" })
// 2. inspect: price and input schema
omnial_inspect({ tool: "ncei/find-stations" })
// 3. learn: read the usage guide at runtime
omnial_learn({ tool: "ncei/find-stations" })
// 4. run: price the exact call first, then run it
omnial_execute({ tool: "ncei/find-stations", input: { /* see input_schema */ }, dry_run: true })
omnial_execute({ tool: "ncei/find-stations", input: { /* ... */ } })
// 5. settle: the call is charged when it finishes, nothing to doNot connected yet? Point your MCP client at https://mcp.eden-engine.com/mcp, then copy a config for your client.
