## Exfil surface

No private-data -> untrusted-input -> outbound path in this server alone: no tool is tagged private-data 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. | `mcp__servicebuddy__audit_repair_quote` `mcp__servicebuddy__get_evaluated_savings` |
| 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 (1)

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

### `audit_repair_quote`

- 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.
- Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data.

Description, as the server wrote it:

```untrusted-server-text
Audit a mechanic quote, repair estimate, or bill from an image URL or pasted text against US fair market labor rates and parts benchmarks. Identifies potential overcharges, checks state statutory inspection fee caps, flags OBD-II diagnostic inconsistencies, and matches active shop coupons or manufacturer rebates to reduce out-of-pocket costs without adversarial confrontation. US only.
```

## Only reads (1)

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

### `get_evaluated_savings`

- The name "get_evaluated_savings" says "get": a word for reading.
- Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data.

Description, as the server wrote it:

```untrusted-server-text
Find the best current auto-service deal near a US ZIP or metro and see what you'd actually pay. Returns the local typical price for the service (oil change, brakes, battery, diagnostic, coolant flush, tire rotation, tires), the best current coupon, discount, or rebate, and the net out-of-pocket "effective price" after discounts and rebates, with caveats. Optionally compares against a shop quote the user already has. Use when someone asks what a repair should cost, whether a quote is fair, or where to find a coupon. US only; 16 major metros are priced locally, other ZIPs use national averages.
```

## Claude Code permissions

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

```json
{
  "permissions": {
    "allow": [
      "mcp__servicebuddy__get_evaluated_savings"
    ],
    "ask": [
      "mcp__servicebuddy__audit_repair_quote"
    ],
    "deny": []
  }
}
```

Capability tags behind the rules (a read tagged outbound is asked about):

- `mcp__servicebuddy__get_evaluated_savings`: untrusted-input
- `mcp__servicebuddy__audit_repair_quote`: untrusted-input

## Remote posture

What an anonymous client saw at the remote endpoint, last 2026-10-22T14:48:45.615Z, unchanged since 2026-10-22T14:48:45.615Z. 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 | `1` |
| 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 1 tool that changes things (1 write). Whether a call also works without credentials was not tested: tools are never called.

https://www.servicebuddy.help/mcp: tools/list returned 2 tools to an anonymous client, including audit_repair_quote (write)
```
