## Exfil surface

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

| Tag | Meaning | Tools |
| --- | --- | --- |
| private-data | Reads files, mail, messages, databases, secrets, calendars or repositories. | none |
| untrusted-input | Brings in text someone else can write: web pages, inbound email, messages, issues and comments. | none |
| outbound | Can carry data to people or systems: it sends, posts or publishes, or takes a recipient, channel or URL. | none |

## Findings

No check matched anything in these tool definitions.


## Changes things (6)

Creates or changes something that can be changed back. Claude Code: ask.

### `earthquake_details`

- Nothing in its name or description says what it does, so it is counted as a write.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.

Description, as the server wrote it:

```untrusted-server-text
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.
```

### `earthquakes_near`

- Nothing in its name or description says what it does, so it is counted as a write.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.

Description, as the server wrote it:

```untrusted-server-text
Earthquakes within a radius of coordinates, a US ZIP code or a US town, over the last 1-365 days, newest first, each with its distance, plus the largest in the window. 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.
```

### `largest_on_record`

- Nothing in its name or description says what it does, so it is counted as a write.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.

Description, as the server wrote it:

```untrusted-server-text
The largest earthquakes in QuakeIndex's copy of the USGS catalogue for a US state, county ('Kern County, CA'), town ('Ridgecrest, CA') or ZIP code, with the catalogue span it covers. 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.
```

### `latest_earthquakes`

- Nothing in its name or description says what it does, so it is counted as a write.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.

Description, as the server wrote it:

```untrusted-server-text
The most recent earthquakes recorded by USGS worldwide or only in the United States, newest first, filtered by minimum magnitude and hours back (up to 7 days). Use for 'any earthquakes today?' questions. 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.
```

### `place_activity`

- Nothing in its name or description says what it does, so it is counted as a write.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.

Description, as the server wrote it:

```untrusted-server-text
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. 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.
```

### `was_that_an_earthquake`

- Nothing in its name or description says what it does, so it is counted as a write.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.

Description, as the server wrote it:

```untrusted-server-text
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.
```

## Claude Code permissions

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

https://quakeindex.com/mcp: tools/list returned 6 tools to an anonymous client, including latest_earthquakes (write), earthquakes_near (write), earthquake_details (write), place_activity (write), was_that_an_earthquake (write) and 1 more
