Requests go through mcptry because browsers can't call most MCP servers directly. Header values are sent to the server for that request only and are never stored or logged.

add_readings

Append water readings to an existing log. Requires a bearer key.

}

check_readings

Check a list of pool or spa water readings for things that cannot be true, and compare pH, free chlorine and bromine against the ranges published on the US CDC pages. Deterministic arithmetic only - no AI. It does not decide whether a pool is legally compliant, and it does not know your local code.

Argument	Type	Description
as_of	string	Treat this date as "today" (YYYY-MM-DD) when rejecting future timestamps. Defaults to the server date.
readings*	array	Readings to check. Each: {at:"YYYY-MM-DDTHH:MM", kind:"pool\|hot_tub\|splash_pad\|wading_pool\|other", ph?:number, free_chlorine_ppm?:number, total_chlorine_ppm?:number, bromine_ppm?:number, cyanuric_acid_ppm?:number, water_temp_f?:number, disinfectant?:"chlorine\|bromine\|none", method?:"dpd\|test_strip\|meter\|other", by?:"who tested"}.
