## 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__stealth__check_building_availability` `mcp__stealth__get_pricing` `mcp__stealth__place_order` `mcp__stealth__prepare_availability_inquiry` `mcp__stealth__prepare_order` `mcp__stealth__submit_availability_inquiry` |
| outbound | Can carry data to people or systems: it sends, posts or publishes, or takes a recipient, channel or URL. | `mcp__stealth__place_order` |

## Findings

No check matched anything in these tool definitions.


## Changes things (4)

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

### `place_order`

- The description's first verb is "create": a word for a change.
- 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
Creates a binding service order and queues staff and customer confirmations after validation. Before placing an order, show the actual customer the exact building, bandwidth, monthly price, installation fee, term and linked service terms. Obtain that customer’s explicit acceptance and confirmation that they are authorized to order for the company. Never infer consent or authority from an availability or pricing inquiry. Pass accept_terms=true and authorized_to_order=true only after that explicit customer confirmation. Retry the same order_token after a network failure; never prepare a new order just to retry. No payment is collected at checkout.
```

### `prepare_availability_inquiry`

- 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
Prepare a request for manual availability review, including unverified or off-network addresses. Supply an address token from a building check, or the entered address and NYC borough. This step sends nothing. Before sending an availability inquiry, show the actual customer the address, requested bandwidth, contact details, message and returned customer data notice. Obtain explicit approval to share them with Stealth. This requests a manual review; it does not place an order, confirm availability or promise installation timing. Never infer consent from an address search or pricing inquiry.
```

### `prepare_order`

- 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
Recheck the explicitly selected building and create a signed, time-limited quote for a published bandwidth. This does not place an order. Show the returned review and linked terms to the actual customer before requesting acceptance. Before placing an order, show the actual customer the exact building, bandwidth, monthly price, installation fee, term and linked service terms. Obtain that customer’s explicit acceptance and confirmation that they are authorized to order for the company. Never infer consent or authority from an availability or pricing inquiry.
```

### `submit_availability_inquiry`

- The name "submit_availability_inquiry" says "submit": a word for a change.
- 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
Save the customer-approved availability inquiry and queue staff and customer confirmations. Before sending an availability inquiry, show the actual customer the address, requested bandwidth, contact details, message and returned customer data notice. Obtain explicit approval to share them with Stealth. This requests a manual review; it does not place an order, confirm availability or promise installation timing. Never infer consent from an address search or pricing inquiry. Pass approve_submission=true only after that explicit approval. Retry the same inquiry_token after a network failure; never prepare another inquiry merely to retry.
```

## Only reads (2)

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

### `check_building_availability`

- The description's first verb is "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
Search a New York City business address. Returns up to five verified address candidates with signed address tokens and current eligibility. Ask the customer to select the correct building when there is more than one candidate. An unverified address requires manual review and cannot be ordered. Before placing an order, show the actual customer the exact building, bandwidth, monthly price, installation fee, term and linked service terms. Obtain that customer’s explicit acceptance and confirmation that they are authorized to order for the company. Never infer consent or authority from an availability or pricing inquiry.
```

### `get_pricing`

- The name "get_pricing" says "get": a word for reading.
- Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data. The description's first sentence says "read" and "internet": it reads web pages, which anyone can write.

Description, as the server wrote it:

```untrusted-server-text
Read current published Dedicated Internet bandwidth prices, the installation fee, initial term, billing and service terms. Prices apply to eligible buildings already connected to Stealth; check the building before preparing an order. Before placing an order, show the actual customer the exact building, bandwidth, monthly price, installation fee, term and linked service terms. Obtain that customer’s explicit acceptance and confirmation that they are authorized to order for the company. Never infer consent or authority from an availability or pricing inquiry.
```

## Claude Code permissions
