**4 tools: 4 change things.**

| Group | Class | Tools | Claude Code |
| --- | --- | --- | --- |

| Changes things | write | 4 | ask |
| Only reads | read | 0 | 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 `seasonal_checklist` ([annotation-conflict](https://anlyon.dev/methodology#annotation-conflict))

```untrusted-server-text
The server marks "seasonal_checklist" 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 description's first verb is "generate": a word for a change.
```


## Changes things (4)

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

### `due_services`

- 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
Work out which car maintenance services (oil, tires, brakes, filters, coolant, plugs, transmission, battery) are due, due soon or ok from the current odometer and optional service history, and name the next one. Use to check what a car needs now. Do NOT use for prices (use service_cost_estimate) or a 12-month plan (use service_timeline).
```

### `seasonal_checklist`

- The description's first verb is "generate": 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
Generate a preventive car checklist for spring, summer, fall or winter, grouped by area (tires, battery, fluids, wipers and more) and tuned for a hot, cold or mixed climate. Use when getting a car ready for the season ahead. Do NOT use for mileage-based maintenance status (use due_services).
```

### `service_cost_estimate`

- 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
Estimate typical US parts-and-labor price ranges (USD) for a list of car maintenance services at an economy, mid or luxury shop, with low and high totals. Use when budgeting for known services. An estimate, not a quote. Do NOT use to find which services are due (use due_services).
```

### `service_timeline`

- 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
Project the next 12 months of driving and list which maintenance services fall due in each month, from the odometer and monthly distance. Use when planning maintenance over the coming year. Do NOT use for what is due right now (use due_services) or prices (use service_cost_estimate).
```

## Claude Code permissions

For `.claude/settings.json`, assuming the server is installed as `service-schedule`:

```json
{
  "permissions": {
    "allow": [],
    "ask": [
      "mcp__service-schedule__due_services",
      "mcp__service-schedule__service_cost_estimate",
      "mcp__service-schedule__service_timeline",
      "mcp__service-schedule__seasonal_checklist"
    ],
    "deny": []
  }
}
```

## Remote posture

What an anonymous client saw at the remote endpoint, last 2026-10-22T15:22:04.139Z, unchanged since 2026-10-22T15:22:04.139Z. No credentials were sent and no tool was called. Values are shown as the endpoint returned them. Method: https://anlyon.dev/methodology#remote-posture

| Fact | Observed |
| --- | --- |
| Reachable | `yes` |
| HTTP status of an anonymous initialize | `200` |
| tools/list served without credentials | `yes` |
| Tools that change things, listed without credentials | `4` |
| Protocol version | `2025-06-18` |
| WWW-Authenticate on 401 | `not observed` |

| Dynamic client registration | `not observed` |
| Client ID metadata documents | `not observed` |

- **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 4 tools that change things (4 write). Whether a call also works without credentials was not tested: tools are never called.

https://service-schedule.magicteams.ai/mcp: tools/list returned 4 tools to an anonymous client, including due_services (write), service_cost_estimate (write), service_timeline (write), seasonal_checklist (write)
