## Findings

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

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

annotations: {"readOnlyHint":true,"destructiveHint":false,"idempotentHint":true,"openWorldHint":true}; The name "add_business_days" says "add": a word for a change.
```


## Changes things (3)

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

### `add_business_days`

- The name "add_business_days" says "add": a word for a change.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.
- Findings: warn annotation-conflict

Description, as the server wrote it:

```untrusted-server-text
Use this when the user needs a date N working days from another date: delivery and shipping estimates, payment or settlement terms, notice periods, SLA and deadline questions. Skips weekends and the public holidays of the country or region, reports exactly which days were skipped, and flags any date in the range that independent sources disagree about.
```

### `check_business_day`

- 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
Use this when the user asks whether one specific date is a working day, a public holiday, or whether businesses and banks are open. Names the holiday if there is one, and reports whether independent holiday sources agree on that date.
```

### `cross_check_holidays`

- 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
Use this when accuracy matters more than speed, or when the user questions whether a holiday date is right: contracts, payroll, settlement, compliance deadlines. Compares the national holiday list for a country and year across three independent providers and reports exactly where they agree and disagree, rather than picking one.
```

## Only reads (1)

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

### `list_public_holidays`

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

Description, as the server wrote it:

```untrusted-server-text
Use this when the user asks what the public holidays are in a country or region for a given year, when a particular holiday falls, or how many holidays a year has. Covers 200+ countries with state and province detail. Do not use it for working-day arithmetic; use add_business_days for that.
```

## Claude Code permissions
