## Exfil surface

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

| 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__corex-booking__book_with_deposit` `mcp__corex-booking__get_business` `mcp__corex-booking__get_open_times` `mcp__corex-booking__search_businesses` |
| outbound | Can carry data to people or systems: it sends, posts or publishes, or takes a recipient, channel or URL. | `mcp__corex-booking__book_with_deposit` |

## Findings

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

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

annotations: {"readOnlyHint":true,"openWorldHint":true}; The name "get_open_times" says "get": a word for reading.
```


## Changes things (2)

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

### `book_with_deposit`

- Nothing in its name or description says what it does, so it is counted as a write.
- Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data.
- Tag outbound: The input takes a destination (input.phone): what the tool writes goes there.

Description, as the server wrote it:

```untrusted-server-text
Hold a time for the homeowner and get a card payment link for the deposit. Ask the homeowner for their name, phone, service address and a short description of the problem first. The time is held for 20 minutes and is booked only when they pay. Tell them: The deposit comes off your final bill. Refunds are up to the business.
```

### `get_open_times`

- The name "get_open_times" says "get": a word for reading.
- The description's first verb is "open": a word for a change.
- 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.
- Findings: warn annotation-conflict

Description, as the server wrote it:

```untrusted-server-text
Open appointment times for a business over the next days (default 7, max 14). Pass a start value to book_with_deposit.
```

## Only reads (2)

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

### `get_business`

- The name "get_business" 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
Details for one business from search_businesses: name, services, hours, deposit and the refund policy.
```

### `search_businesses`

- The name "search_businesses" says "search": 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 local service businesses that take AI bookings with a deposit, by trade (plumbing, hvac, appliance repair, cleaning, electrical, pest control...) and 5-digit zip. Returns business_id values for the other tools.
```
