Sea Water Level Near a Norwegian Coordinate (Kartverket)
kartverkettide/water-levels
Returns the sea water level around a point on the Norwegian coast for a time window (UTC): the nearest tide location, the reference level, and time series of observed levels, predicted levels, weather effect and forecast (type all), or only observed or predicted levels. Values are centimetres relative to the chosen reference (chart datum, mean sea level or NN2000). The window must not exceed 7 days. Points arrive every 10, 20, 30 or 60 minutes, at most 2000 per series (pointCount and truncated say when more existed). A position too far from the coast, or a window with no data, returns an empty series list and a noData reason.

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: "kartverkettide/water-levels" })
// 3. learn: read the usage guide at runtime
omnial_learn({ tool: "kartverkettide/water-levels" })
// 4. run: price the exact call first, then run it
omnial_execute({ tool: "kartverkettide/water-levels", input: { /* see input_schema */ }, dry_run: true })
omnial_execute({ tool: "kartverkettide/water-levels", 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.
