## Exfil surface

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

| Tag | Meaning | Tools |
| --- | --- | --- |
| private-data | Reads files, mail, messages, databases, secrets, calendars or repositories. | `mcp__paydayloan-help__get_state_payday_rules` |
| untrusted-input | Brings in text someone else can write: web pages, inbound email, messages, issues and comments. | `mcp__paydayloan-help__get_state_payday_rules` |
| 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.

### `payday_loan_cost`

- 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
The paydayloan.help cost calculator: from the amount borrowed, the fee per $100 and the days until due, returns the APR, the fee per period, total fees after a number of fee-only renewals, the principal still owed, and the same amount as a federal credit union payday alternative loan (PAL) at the 28% maximum rate: monthly payment and total interest.
```

## Only reads (2)

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

### `get_state_payday_rules`

- The name "get_state_payday_rules" says "get": a word for reading.
- Tag private-data: The description's first sentence says "database": it reads databases.
- Tag untrusted-input: The description's first sentence says "url": it reads web pages, which anyone can write.

Description, as the server wrote it:

```untrusted-server-text
One state's (or DC's) payday loan law as published on paydayloan.help: whether payday loans are allowed, maximum loan, term, fee or rate cap, rollovers, cooling-off, concurrent loans, extended payment plan, database, collection limits, other borrower rights, the regulator with license-lookup and complaint links, the statute citation, research date and confidence level, with every source URL.
```

### `list_states_by_payday_rule`

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

Description, as the server wrote it:

```untrusted-server-text
Lists states (50 plus DC) by their payday loan rules as published on paydayloan.help: filter by status (allowed with limits, installment-only, or typical payday loans not allowed), by whether state law requires an extended payment plan, or by a list of state codes to compare. Each row gives the status, a one-paragraph summary, the payment-plan flag, research confidence and the state page link.
```

## Claude Code permissions

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

```json
{
  "permissions": {
    "allow": [
      "mcp__paydayloan-help__get_state_payday_rules",
      "mcp__paydayloan-help__list_states_by_payday_rule"
    ],
    "ask": [
      "mcp__paydayloan-help__payday_loan_cost"
    ],
    "deny": []
  }
}
```

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

- `mcp__paydayloan-help__get_state_payday_rules`: private-data, untrusted-input

- **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://paydayloan.help/mcp: tools/list returned 3 tools to an anonymous client, including payday_loan_cost (write)
