**9 tools: 1 change things and 8 only read.**

| Group | Class | Tools | Claude Code |
| --- | --- | --- | --- |
| Deletes or cancels | destructive | 0 | deny |
| Can't be undone | irreversible | 0 | ask |
| Changes things | write | 1 | ask |
| Only reads | read | 8 | allow |

## 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

- **warn** Annotations that disagree with the tool in `query_range` ([annotation-conflict](https://anlyon.dev/methodology#annotation-conflict))

```untrusted-server-text
The server marks "query_range" read-only (readOnlyHint: true), and its own name, description or input give the class "write".

annotations: {"readOnlyHint":true,"destructiveHint":false,"idempotentHint":true,"openWorldHint":false}; The name "query_range" says "query": a word for reading.
```


## Changes things (1)

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

### `query_range`

- The name "query_range" says "query": a word for reading.
- The description's first verb is "evaluate": a word for a change.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.
- Findings: warn annotation-conflict

Description, as the server wrote it:

```untrusted-server-text
Evaluate a PromQL query in a range of time
```

## Only reads (8)

Looks things up and changes nothing. Claude Code: allow.

### `get_alert`

- The name "get_alert" says "get": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Use this as the primary tool to get information about a specific alert. An alert is the representation of a violation of an alert policy. This is useful for understanding the details of a specific alert.
```

### `get_alert_policy`

- The name "get_alert_policy" says "get": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Use this as the primary tool to get information about a specific alerting policy. Alerting policies define the conditions under which you want to be notified about issues with your services. This is useful for understanding the details of a specific alert configuration.
```

### `get_dashboard`

- The name "get_dashboard" says "get": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Use this as the primary tool to retrieve a single specific custom monitoring dashboard from a Google Cloud project using the resource name of the requested dashboard. Custom monitoring dashboards let users view and analyze data from different sources in the same context. This is often used as a follow on to list_dashboards to get full details on a specific dashboard.
```

### `list_alert_policies`

- The name "list_alert_policies" says "list": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Use this as the primary tool to list the alerting policies in a Google Cloud project. Alerting policies define the conditions under which you want to be notified about issues with your services. This is useful for understanding what alerts are currently configured.
```

### `list_alerts`

- The name "list_alerts" says "list": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Use this as the primary tool to list the alerts in a Google Cloud project. An alert is the representation of a violation of an alert policy. This is useful for understanding current and past violations of an alert policy.
```

### `list_dashboards`

- The name "list_dashboards" says "list": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Use this as the primary tool to retrieve a list of existing custom monitoring dashboards in a Google Cloud project. Custom monitoring dashboards let users view and analyze data from different sources in the same context. This is useful for understanding what custom dashboards are currently configured and available in a given project.
```

### `list_metric_descriptors`

- The name "list_metric_descriptors" says "list": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Use this as the primary tool to discover the types of metrics available in a Google Cloud project. This is a good first step to understanding what data is available for monitoring and building dashboards or alerts.
```

### `list_timeseries`

- The name "list_timeseries" says "list": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Lists time series data from the Google Cloud Monitoring API
```

## Claude Code permissions

For `.claude/settings.json`, assuming the server is installed as `monitoring`:

```json
{
  "permissions": {
    "allow": [
      "mcp__monitoring__list_timeseries",
      "mcp__monitoring__get_alert_policy",
      "mcp__monitoring__list_alert_policies",
      "mcp__monitoring__get_alert",
      "mcp__monitoring__list_alerts",
      "mcp__monitoring__list_metric_descriptors",
      "mcp__monitoring__list_dashboards",
      "mcp__monitoring__get_dashboard"
    ],
    "ask": [
      "mcp__monitoring__query_range"
    ],
    "deny": []

- **warn** Tools that change things, listed to anyone ([unauth-remote-writes](https://anlyon.dev/methodology#unauth-remote-writes))

```untrusted-server-text
The endpoint served tools/list without credentials, and the list has 1 tool that changes things (1 write). Whether a call also works without credentials was not tested: tools are never called.

https://monitoring.googleapis.com/mcp: tools/list returned 9 tools to an anonymous client, including query_range (write)
