## 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__keyready__refer_to_broker` |
| outbound | Can carry data to people or systems: it sends, posts or publishes, or takes a recipient, channel or URL. | `mcp__keyready__refer_to_broker` |

## Findings

No check matched anything in these tool definitions.


## Can't be undone (1)

Sends, pays, publishes or merges: once done, it cannot be taken back. Claude Code: ask.

### `refer_to_broker`

- The description's first verb is "send": a word for sending, and what is sent cannot be taken back.
- Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data.
- Tag outbound: The description's first verb is "send": it sends or publishes something to other people. The input takes a destination (input.phone): what the tool writes goes there.

Description, as the server wrote it:

```untrusted-server-text
Send the user’s situation and readiness report to Goodlend Mortgage Brokers, a licensed mortgage broker, who will contact them. ONLY call this after you have shown the user this disclosure and they have explicitly agreed in this conversation: This site is run by Goodlend Mortgage Brokers (Gariwed Falls Pty Ltd (ACN 682 875 798) ATF Holvor Investments Unit Trust No. 1), Credit Representative 556461 of Connective Credit Services Pty Ltd, ACL 389328. If you ask to be contacted, your details and report go only to us. If you take out a loan with our help, the lender pays us commission, as set out in the Credit Guide we give you before we help; you never pay us a fee. Collect their name, email and phone. The user then gets an email link to confirm before the broker sees anything. Never call it on the user’s behalf without that agreement.
```

## Changes things (3)

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

### `assess_home_loan_readiness`

- 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
Check a borrower’s situation against each Australian lender’s published rules. Returns how many lenders it fits, borrowing power, LVR, stamp duty, grants, 5% Deposit Scheme eligibility, profession LMI waivers, the fastest fixes and a link to the full interactive report.
```

### `calculate_stamp_duty`

- 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
Exact 2026–27 transfer (stamp) duty for any Australian state or territory, including first home buyer concessions, owner-occupier rates, the First Home Owner Grant and foreign purchaser surcharge.
```

### `check_5_percent_deposit_scheme`

- 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
Check eligibility for the Australian Government 5% Deposit Scheme (First Home Guarantee) or Family Home Guarantee (single parents, 2% deposit), including the property price cap for the area.
```

## Only reads (1)

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

### `list_lender_rates`

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

Description, as the server wrote it:

```untrusted-server-text
Live variable principal-and-interest home loan rates at a given LVR from lenders’ Open Banking product data (as of 2026-10-25). Lender names are masked.
```

## Claude Code permissions

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

```json
{
  "permissions": {
    "allow": [
      "mcp__keyready__list_lender_rates"
    ],
    "ask": [
      "mcp__keyready__assess_home_loan_readiness",
      "mcp__keyready__calculate_stamp_duty",
      "mcp__keyready__check_5_percent_deposit_scheme",
      "mcp__keyready__refer_to_broker"
    ],
    "deny": []
  }
}
```

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