## Findings

- **info** The word "credentials" in `fetch` ([credentials-mention](https://anlyon.dev/methodology#credentials-mention))

```untrusted-server-text
The description mentions "credential".

description: "...only content retrieval with no account, credential, payment, or live-price side effects."
```


## Changes things (1)

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

### `recommend_account_plan`

- 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
Recommend a sales-assisted Blocksize account plan from expected live-call volume, team size, recurring use, and SLA needs. This is free and does not collect contact details, create an entitlement, or start a purchase.
```

## Only reads (8)

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

### `fetch`

- The name "fetch" says "fetch": a word for reading.
- Findings: info credentials-mention

```untrusted-server-text
Fetch one document or instrument guide returned by search. This is free, read-only content retrieval with no account, credential, payment, or live-price side effects.
```

### `get_market_data_endpoint`

- The name "get_market_data_endpoint" says "get": a word for reading.

Description, as the server wrote it:

```untrusted-server-text

```

### `get_pricing_info`

- The name "get_pricing_info" says "get": a word for reading.

Description, as the server wrote it:

```untrusted-server-text

```

### `get_product_catalog`

- The name "get_product_catalog" says "get": a word for reading.

Description, as the server wrote it:

```untrusted-server-text

```
