Koskamo

GageLink MCP

An open-source MCP server that provides AI agents with hydrology data including river levels, streamflow, flood forecasts, and basin information from multiple agencies. It ensures data integrity by attaching units, datums, and record quality metadata to every value, preventing silent errors when comparing measurements like river stage against levee crests.

Package and access

What you can do with it

  • Retrieve current river levels and compare them to flood stage thresholds
  • Calculate freeboard between water levels and surveyed levee crests with correct datum offsets
  • Access flood forecasts for the next few days and check against flood categories
  • Determine the drainage basin size for a specific river point
