## Status

Pod connected to usgs-water-mcp-server on 2026-09-05. It answered and listed its tools, responding in 22432ms.

It identifies itself as `usgs-water-mcp-server` version 0.2.3, speaking sse. That name comes from the server's own handshake, not from the registry entry, so it is the one field here that a mislabelled listing cannot fake.

- `water_list_parameters`
- `water_find_sites`
- `water_get_readings`
- `water_get_series`
