6 of these tools change something. Run those as governed actions.

Declare what an action changes, and Anlyon puts it under a shared limit, binds every approval to the exact request, and grades the outcome. It works on any HTTPS API you can describe as an action.

Anlyon does not run, proxy or govern this MCP server. A tool your own code calls directly is not routed through Anlyon and is not governed by it.

    Description, as the server wrote it
    Everything QuakeIndex holds about one earthquake by USGS event id (or a QuakeIndex/USGS event URL), including every revision it observed — e.g. 'magnitude revised from 4.1 to 3.9'. An automatic solution is a first estimate and says so. Data: USGS, as held by QuakeIndex. Each result includes its source, when the data was last confirmed, and links to the QuakeIndex and USGS event pages. No predictions and no warnings: results name ShakeAlert and MyShake as the sources of earthquake early warning.

    Description, as the server wrote it
    The QuakeIndex score for a US state or county: the last 7 days' earthquake activity ranked 0-100 against that place's own 10-year history, its label (quiet / typical / elevated / unusual) and the normal band for a week. It describes observed activity and is NOT a forecast or a risk rating. A missing score is never zero. Data: USGS, as held by QuakeIndex.

    Description, as the server wrote it
    Checks whether USGS has recorded an earthquake that someone who just felt shaking a few minutes ago could have felt: large and close enough for an estimated intensity of MMI 2+ at their location (Atkinson & Wald 2007, the equation USGS Did You Feel It? uses). Answers yes (with the event), not_yet_reported (nothing yet, but small quakes take minutes to be catalogued, so this is not a no), or no; smaller quakes recorded nearby are listed as too small to feel. The result links USGS Did You Feel It? for reporting shaking. Data: USGS, as held by QuakeIndex. Each result includes its source, when the data was last confirmed, and links to the QuakeIndex and USGS event pages. No predictions and no warnings: results name ShakeAlert and MyShake as the sources of earthquake early warning.

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 private-data or untrusted-input or outbound.

Reads private data0
Reads files, mail, messages, databases, secrets, calendars or repositories.
Reads text others write0
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.

Findings

Matches of fixed checks, with the text they matched.

No check matched anything in these tool definitions. That is not a safety guarantee.

History

Changes to its tool definitions and to its remote endpoint, newest first.

No change seen yet. Its tools are rescanned every day, and a remote endpoint is looked at once a week.

Allow the reads, ask before a change or a way out, deny the deletes. Paste into .claude/settings.json.

Tools that only read are allowed, tools that change things ask first, tools that delete or cancel are denied. A read that can send data out (it takes a URL, say) asks first too. It assumes the server is installed as quakeindex. Review it before you use it.

Pin

Keep the decision: fail CI when the tools change, follow every change, or show a badge.

Pin in CI

Fail a build when the tools you reviewed are not the tools the server serves today.
