**3 tools: 1 do something that can't be undone and 2 only read.**

| Group | Class | Tools | Claude Code |
| --- | --- | --- | --- |

## Exfil surface

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

| 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. | none |
| outbound | Can carry data to people or systems: it sends, posts or publishes, or takes a recipient, channel or URL. | `mcp__breach-notification-deadlines__who_to_notify` |

## 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.

### `who_to_notify`

- The name "who_to_notify" says "notify": a word for sending, and what is sent cannot be taken back.
- Tag outbound: The name "who_to_notify" says "notify": it sends or publishes something to other people.

Description, as the server wrote it:

```untrusted-server-text
Works out every data breach notice a company owes and the deadline for each. Give affected (how many people in each US state or country), the data types exposed (for example ssn, drivers_license, payment_card, financial_account, medical, health_insurance, username_password, biometric, passport, dob, email_address), whether the data was encrypted with the key kept safe, the date the breach was discovered, and flags: sec_registrant (US public company), sector (hipaa_covered_entity, hipaa_business_associate, glba_financial, health_app, nydfs_licensee) and role (owner, or service_provider holding data for another company). Returns each notice owed (people affected, state attorneys general, credit bureaus, HHS, SEC Form 8-K, FTC, EU and UK data protection authorities, Canada, Australia) with the deadline as a date where the law sets a fixed period, the deadline rule in words, what the notice must contain, how to send it and the official source, earliest first. Unclear cases give the SAFE answer (notice treated as required) plus what it depends on. Free.
```

## Only reads (2)

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

### `list_breach_laws`

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

Description, as the server wrote it:

```untrusted-server-text
Lists breach notification laws with who is covered, which data types trigger them, encryption exemptions, every notice with its deadline rule and threshold, penalties and the official source. Filter by US state, country (ISO code or name) or scope (us_state, us_federal_sector, country, region). Free.
```

### `list_capabilities`

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

Description, as the server wrote it:

```untrusted-server-text
Lists coverage (US states, US federal sector rules, countries), the date the data was last checked, and related Nero Labs Rules servers. Free.
```

## Claude Code permissions

For `.claude/settings.json`, assuming the server is installed as `breach-notification-deadlines`:

```json
{
  "permissions": {
    "allow": [
      "mcp__breach-notification-deadlines__list_capabilities",
      "mcp__breach-notification-deadlines__list_breach_laws"
    ],
    "ask": [
      "mcp__breach-notification-deadlines__who_to_notify"
    ],
    "deny": []
  }
}
```

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

- `mcp__breach-notification-deadlines__who_to_notify`: outbound

## Remote posture

What an anonymous client saw at the remote endpoint, last 2026-10-22T14:53:38.697Z, unchanged since 2026-10-22T14:53:38.697Z. No credentials were sent and no tool was called. Values are shown as the endpoint returned them. Method: https://anlyon.dev/methodology#remote-posture

| Fact | Observed |
| --- | --- |
| Reachable | `yes` |
| HTTP status of an anonymous initialize | `200` |
| tools/list served without credentials | `yes` |
| Tools that change things, listed without credentials | `1` |
| Protocol version | `2025-06-18` |
| WWW-Authenticate on 401 | `not observed` |
| resource_metadata in WWW-Authenticate | `none` |
| RFC 9728 protected resource metadata | `https://breach-notification-deadlines.nerolabs.workers.dev/.well-known/oauth-protected-resource/mcp` |
| Authorization servers | `none` |
| Legacy HTTP+SSE transport | `no` |
| Dynamic client registration | `not observed` |
| Client ID metadata documents | `not observed` |

- **high** 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 irreversible). Whether a call also works without credentials was not tested: tools are never called.

https://breach-notification-deadlines.nerolabs.workers.dev/mcp: tools/list returned 3 tools to an anonymous client, including who_to_notify (irreversible)
