Safecast Device Readings (Radiation and Air Quality)
safecasttt/device-readings
Returns the latest record and short recent history of one Safecast device: location, place name, temperature, humidity, pressure, battery, radiation counts per minute and particulate values where the device measures them, plus up to five recent Geiger, particulate and location entries. Takes the device_id from the recent-devices tool (the digits of a note:dev: device). An unknown id is refused as VALIDATION. Safecast data as served by Eden Engine, not an official Safecast 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.
Data source
Radiation and air quality readings from Safecast (safecast.org), a citizen science project whose data is released to the public domain. No attribution is required; we credit Safecast as a courtesy. Served by Eden Engine; not an official Safecast product.
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: "safecasttt/device-readings" })
// 3. learn: read the usage guide at runtime
omnial_learn({ tool: "safecasttt/device-readings" })
// 4. run: price the exact call first, then run it
omnial_execute({ tool: "safecasttt/device-readings", input: { /* see input_schema */ }, dry_run: true })
omnial_execute({ tool: "safecasttt/device-readings", 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.
