Preview access · not provider authentication
The vk_preview_* token belongs to Vinkius preview infrastructure. It lets Claude discover and display the capabilities of Runoff Calculator, so you can see the experience inside your AI.
It does not authenticate your account with Runoff Calculator. Actions requiring credentials or live account data may not run until you activate the Connector and authorize the service.

FAQ
Questions Runoff Calculator owners ask.
- 01
What is the SCS Curve Number method?
It is an empirical model used to estimate direct runoff from precipitation in small watersheds based on soil type and land cover.
- 02
How do I account for wet soil conditions?
You can use the calculate_adjusted_cn capability to adjust the base Curve Number for AMC I (dry), AMC II (average), or AMC III (wet) conditions.
- 03
Can I calculate runoff for multiple storm events at once?
Yes, the generate_storm_series_runoff capability allows you to provide a list of rainfall depths to predict a series of runoff results.
