    Why it is in this group

    • The name "disable_alert_relay" says "disable": a word for a change.
    • The server marks it destructive (destructiveHint: true).

    What it can reach

    • untrusted-inputThe server marks it openWorldHint: true: it reaches things outside the server's own data.
    Description, as the server wrote it
    Ends this API key's ArrowMem Guard alert relay enrolment. No arguments. Your family link stops resolving, your old topic gets one fixed notice that the relay ended, and every relay attribute is removed from your key's row; it mints nothing, and calling it again is a no-op. Your key, usage, cap and subscription are untouched; call enrol_alert_relay afterward to enrol again. Paid tool - requires a valid API key. Spends one call.

    Why it is in this group

    • The server marks it destructive (destructiveHint: true).

    What it can reach

    • untrusted-inputThe server marks it openWorldHint: true: it reaches things outside the server's own data.
    Description, as the server wrote it
    Enrols this API key in the ArrowMem Guard alert relay (the watchdog page and the family 'Is It Really Me' check). Mints a relay token stored beside your key and returns an alert topic derived from it (subscribe to it once, in a push notification app, on your own phone), plus a one-time family link you share with the one person you want able to check on you if a call sounds like you and asks for money. No arguments. On an already-enrolled key it returns the SAME topic and no new family link (never re-shown once given). To replace the topic or the link use rotate_alert_relay; to end the enrolment use disable_alert_relay. Honest limit: ArrowMem can derive this topic from what it stores, so a topic is public-by-name the moment it exists - every page sent over it is a fixed, contentless sentence, never your real findings or any personal detail. The family check cannot be faked the same way; an answer comes back through the server, bound to a one-time token, and only proves someone holding the phone tapped Yes or No. Paid tool - requires a valid API key. Spends one call. A family member's own ask also spends one call from your plan, so you can see a leaked link being used.

    Description, as the server wrote it
    Replaces part of this API key's ArrowMem Guard alert relay enrolment. Argument: {"scope": "topic"|"family"|"both"} (required). scope="topic" replaces the relay token only (the old topic gets one notice that it is changing, then stops being used) - your family link keeps working. scope="family" replaces the family link only (the old one stops working) and returns the new link - your topic is unchanged. scope="both" does both. Your key, usage, cap and subscription are untouched. Requires an existing enrolment (enrol_alert_relay). Paid tool - requires a valid API key. Spends one call.

    Description, as the server wrote it
    ArrowMem Guard's machine security sweep, given diagnostic output your own machine (or AI tool) already produced locally - this tool never reaches your machine or network, it only reasons over what you send it. Checks whether a model server and common database, search and notebook services are reachable beyond loopback, plus firewall state, disk encryption, screen lock, and pending OS updates - each resolves to PASS, FAIL, or UNVERIFIABLE (never guessed on missing data). The report leads with the highest-severity unresolved finding and names one first action, then lists every result in full with a complete per-OS fix and verify step. States plainly that a service bound wide is not the same claim as internet-reachable (this tool can see local configuration, not your network path). Limits: no signature or malware detection, no behavioural analysis, no filesystem or traffic monitoring. Nothing you submit is stored, logged, or retained; each call is evaluated in isolation. Paid tool - requires a valid API key.

    Description, as the server wrote it
    Checks whether a self-hosted model server install still matches the hardening guide's defaults, given the diagnostic output your own machine (or AI tool) already produced locally - this tool never reaches your machine or network, it only reasons over what you send it. Checks: host environment variable safety, loopback-only reachability on the model server and reverse proxy ports, the reverse proxy configuration's bind directive and credential enforcement, a unique (non-shared) credential, and disk encryption - each check resolves to PASS, FAIL, or UNVERIFIABLE (never guessed), the same three per-check states the doctor script uses. The OVERALL verdict differs from the script's own stricter rule, which collapses any UNVERIFIABLE into a failed run: this tool reports an UNVERIFIABLE-only result as UNVERIFIABLE, not an asserted failure it never measured. Nothing you submit is stored, logged, or retained; each call is evaluated in isolation and returns a per-check verdict. Cannot verify mesh-only reachability (no live network probe) and cannot detect drift after the moment you ran the diagnostics. Free tool, no API key required.

AI tools whose connectors live in your provider account, not a local file, so they are always reported UNVERIFIABLE by design with where to check instead - never silently omitted. Free and stateless: this call has no memory of a prior one, so it lists what is configured, it does not detect what changed since you last looked. Nothing you submit is stored, logged, or retained.

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.

Exfil surface

Which tools read private data, which read text someone else can write, and which can send data out. One of each is a path a prompt injection can use.

No private-data, untrusted-input, outbound path in this server alone: no tool is tagged outbound.

Reads private data1
Reads files, mail, messages, databases, secrets, calendars or repositories.
Reads text others write5
Brings in text someone else can write: web pages, inbound email, messages, issues and comments.
Can send data out0
Can carry data to people or systems: it sends, posts or publishes, or takes a recipient, channel or URL.

Other servers in the same agent add their own tools to these paths. Audit your whole setup to see them together.

    The endpoint served tools/list without credentials, and the list has 6 tools that change things (3 destructive, 3 write). Whether a call also works without credentials was not tested: tools are never called.

    Matched text
