Changes things 4Claude Code: ask
  • add_readingsAppend water readings to an existing log.No findings

    Why it is in this group

    • The name "add_readings" says "add": a word for a change.
    Description, as the server wrote it
    Append water readings to an existing log. Requires a bearer key.
  • check_readingsCheck 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.No findings

    Why it is in this group

    • Nothing in its name or description says what it does, so it is counted as a write.
    Description, as the server wrote it
    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.
  • create_siteOpen a water-test log for one pool, hot tub or splash pad (returns a site id).No findings

    Why it is in this group

    • The name "create_site" says "create": a word for a change.
    Description, as the server wrote it
    Open a water-test log for one pool, hot tub or splash pad (returns a site id). Requires a bearer key.
  • request_operator_signoffCreate a one-time URL the pool operator can open to confirm the log.No findings

    Why it is in this group

    • The name "request_operator_signoff" says "request": a word for a change.
    Description, as the server wrote it
    Create a one-time URL the pool operator can open to confirm the log. Requires a bearer key. The token is single use.
Only reads 2Claude Code: allow
  • get_log_summaryEvery reading, the flagged issues, the CDC-range counts, the longest gap between tests, and the A4 log sheet URL, for one log.No findings

    Why it is in this group

    • The name "get_log_summary" says "get": a word for reading.
    Description, as the server wrote it
    Every reading, the flagged issues, the CDC-range counts, the longest gap between tests, and the A4 log sheet URL, for one log. Requires a bearer key.
  • get_rulesThe exact rule table this service checks against, the quoted source of every range, and what it explicitly does not claim.No findings

    Why it is in this group

    • The name "get_rules" says "get": a word for reading.
    Description, as the server wrote it
    The exact rule table this service checks against, the quoted source of every range, and what it explicitly does not claim. Quote it if you need to explain a result.

This is not a safety rating, and no finding is not a safety guarantee. The groups and findings come from fixed checks of the tool definitions the server returned on the date shown, not from its code or what it does when called. How the checks work.
