Changes things 3Claude Code: ask
  • fluxproof_check_nowRun a monitor now and return a source- and hash-bound change receipt.1 finding

    Why it is in this group

    • The description's first verb is "run": a word for a change.

    Findings

    • Info

      The input schema at properties.api_key.description mentions "credential".

      Matched text

      inputSchema.properties.api_key.description: "Buyer-owned FluxProof API key; a secret credential."

      What this check looks for
    Description, as the server wrote it
    Run a monitor now and return a source- and hash-bound change receipt. Consumes check quota, stores a receipt and may deliver a configured webhook. Not an idempotent read.

    Annotations the server declares

    • title: Check a watched page now
    • readOnlyHint: false
    • destructiveHint: false
    • idempotentHint: false
    • openWorldHint: true
  • fluxproof_create_monitorCreate a monitor using a buyer-owned FluxProof API key.1 finding

    Why it is in this group

    • The name "fluxproof_create_monitor" says "create": a word for a change.

      Matched text

      inputSchema.properties.api_key.description: "Buyer-owned FluxProof API key; a secret credential."

      What this check looks for
    Description, as the server wrote it
    Create a monitor using a buyer-owned FluxProof API key. Creates persistent state and performs a baseline check, consuming quota. Not idempotent: each call creates a new monitor.

    Annotations the server declares

    • title: Start watching a page
    • readOnlyHint: false
    • destructiveHint: false
    • idempotentHint: false
    • openWorldHint: true
  • fluxproof_get_free_keyCreate a free FluxProof API key: one page, checked daily, for 30 days, no card.1 finding

    Why it is in this group

    • The name "fluxproof_get_free_key" says "get": a word for reading.
    • The description's first verb is "create": a word for a change.

      The description mentions "credential".

      Matched text

      description: "...he key is returned once and is a secret credential."

      What this check looks for
    Description, as the server wrote it
    Create a free FluxProof API key: one page, checked daily, for 30 days, no card. One per network per month. The key is returned once and is a secret credential.

    Annotations the server declares

    • title: Get a free API key
    • readOnlyHint: false
    • destructiveHint: false

    Why it is in this group

    • The name "fluxproof_list_changes" says "list": a word for reading.

    Findings

    • Info

      The input schema at properties.api_key.description mentions "credential".

      Matched text

      inputSchema.properties.api_key.description: "Buyer-owned FluxProof API key; a secret credential."

      What this check looks for
    Description, as the server wrote it
    List recent evidence receipts for a monitor.

    Annotations the server declares

    • title: List recorded changes
    • readOnlyHint: true
    • destructiveHint: false
    • idempotentHint: true
    • openWorldHint: false
  • fluxproof_offerReturn free and paid boundaries and purchase routes without charging.No findings

    Why it is in this group

    • The description's first verb is "return": a word for reading.
    Description, as the server wrote it
    Return free and paid boundaries and purchase routes without charging. Returns the free daily plan, the $9 paid pass (30 days paid once; when offered, also $9 a month through the human checkout, cancel any time), the human checkout link and the agent payment route. Example: {}. Reading the offer charges nothing.

    Annotations the server declares

    • title: Show plans and prices
    • readOnlyHint: true
    • destructiveHint: false
    • idempotentHint: true
    • openWorldHint: false
  • fluxproof_preflightFetch a public URL and return fetchability, size, final URL, title, and content hash without page content or payment.No findings

    Why it is in this group

    • The description's first verb is "fetch": a word for reading.
    Description, as the server wrote it
    Fetch a public URL and return fetchability, size, final URL, title, and content hash without page content or payment. How it works: given one public page address, FluxProof fetches it once and says whether it can watch it; nothing is created or charged. Example: {"url":"https://example.com/"}.

    Annotations the server declares

    • title: Check a public page (free)
    • readOnlyHint: true
    • destructiveHint: false
    • idempotentHint: true
    • openWorldHint: true

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.
