### `bulk_email_security_score`

- 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
Score up to 100 domains' email security in one call (SPF 30, DMARC 40, DKIM 25, MX 5 from live DNS): per-domain score, grade and issues, plus a summary with grade counts, domains missing DMARC or SPF, and the worst 10. For MSPs and agents checking a client or vendor list. Costs $0.50 USDC via x402; errors are not charged.
```

### `check_domain_email_security`

- 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
Free. Look up a domain's MX, SPF (record, DNS lookup count, all qualifier), DMARC (policy, rua) and DKIM (common selectors, key size) from live DNS and list issues. No payment.
```

### `check_email_address`

- 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 one email address: syntax, MX / null MX, disposable domain, role account, free provider; verdict ok / risky / undeliverable. No SMTP probe. Costs $0.01 USDC via x402; errors are not charged.
```

### `email_fix_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
Email security fix plan for one domain: the exact SPF, DKIM and DMARC records to publish (create / replace / keep, name, value, why), in order, with click-path steps for the domain's DNS host and a staged DMARC rollout. Non-sending domains get a lock-down set. Costs $1 USDC via x402; errors are not charged.
```

### `email_security_score`

- 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
Grade a domain's email security 0-100 (A-F): SPF 30, DMARC 40, DKIM 25, MX 5, from live DNS, with findings and the top 3 fixes. Read-only. Costs $0.01 USDC via x402; errors are not charged.
```

### `pricing`

- 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
Free. Prices of the paid tools, payment network and receiving address.
```

## Only reads (1)

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

### `watch_status`

- The name "watch_status" says "status": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Free. Status of a paid email setup watch (created with POST /v1/watch): items, expiry, last check, last webhook delivery and current SPF/DMARC/DKIM/MX state.
```
