**6 tools: 6 change things.**

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

| Only reads | read | 0 | allow |

## Exfil surface

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

| 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. | `mcp__confirme__confirme_courriel` `mcp__confirme__confirme_domaine` `mcp__confirme__confirme_page` `mcp__confirme__confirme_tache` |
| outbound | Can carry data to people or systems: it sends, posts or publishes, or takes a recipient, channel or URL. | `mcp__confirme__confirme_page` |

## Findings

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

```untrusted-server-text
The server marks "confirme_sac" as not read-only (readOnlyHint: false), and its words say it reads.

annotations: {"readOnlyHint":false,"destructiveHint":false,"idempotentHint":false,"openWorldHint":false}; The description's first verb is "get": a word for reading.
```


## Changes things (6)

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

### `confirme_battement`

- Nothing in its name or description says what it does, so it is counted as a write.

Description, as the server wrote it:

```untrusted-server-text
Heartbeat: record that your scheduled or recurring task just ran successfully, under a secret key you choose. Call it at the END of every successful run, every time. Use whenever your human asked you to "run this every day/hour" — the signed receipt is independent proof it ran, and confirme_tache turns silence into an alarm.
```

### `confirme_courriel`

- 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.
- Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data.

Description, as the server wrote it:

```untrusted-server-text
Can this email address receive mail? Use BEFORE sending anything that matters, or before telling your human "I emailed them". Syntax, MX servers, disposable domain, role address, verdict. No message is sent. Signed receipt included.
```

### `confirme_domaine`

- 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.
- Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data.

Description, as the server wrote it:

```untrusted-server-text
Does this domain exist, who registered it, when does it expire, which DNS (A, MX, NS, SPF, DMARC)? Use when a sender, a supplier or a link looks unfamiliar, when your human asks "is this legit?", or before saying "the domain is set up". Signed receipt included.
```

### `confirme_page`

- 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.
- Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data.
- Tag outbound: The input takes a URL (input.url): a request to a URL can carry data to whoever runs it.

Description, as the server wrote it:

```untrusted-server-text
Is this web page really online right now? Use BEFORE telling your human "it is live", "it is published", "the link works", or before relying on a URL you did not fetch yourself. Zero-auth, stateless. Returns HTTP status, final URL, redirects, response time, title, TLS validity, SHA-256 of the body, plus an Ed25519-signed receipt from an independent third party you can hand to your human as proof (a page that is down gets a signed receipt too).
```

### `confirme_sac`

- The description's first verb is "get": a word for reading.
- The server marks it as not read-only (readOnlyHint: false).
- Findings: warn annotation-conflict

Description, as the server wrote it:

```untrusted-server-text
Get your own Confirme key and a FREE starter bag of 100 jelly beans (1 bean = 1 cent = 1 check), plus 20 free beans every day. No email, no form. Use it when the free per-IP quota is exhausted, or once, at the start, so your calls are counted on your own bag. Then reconnect with ?cle=<key> in the server URL. Keep the key secret.
```

### `confirme_tache`

- 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.
- Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data.

Description, as the server wrote it:

```untrusted-server-text
Did my scheduled task really run in the last N seconds? Use when your human asks "did the report go out?", "is the automation still running?", or before you answer "yes, it ran". Reads the heartbeats recorded under the key; silence is the alarm. Signed receipt included.
```

## Claude Code permissions

For `.claude/settings.json`, assuming the server is installed as `confirme`:

```json
{
  "permissions": {
    "allow": [],
    "ask": [
      "mcp__confirme__confirme_page",
      "mcp__confirme__confirme_domaine",
      "mcp__confirme__confirme_courriel",
      "mcp__confirme__confirme_battement",
      "mcp__confirme__confirme_tache",
      "mcp__confirme__confirme_sac"
    ],
    "deny": []
  }
}
```

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

- `mcp__confirme__confirme_page`: untrusted-input, outbound
- `mcp__confirme__confirme_domaine`: untrusted-input
- `mcp__confirme__confirme_courriel`: untrusted-input
- `mcp__confirme__confirme_tache`: untrusted-input

## Remote posture

What an anonymous client saw at the remote endpoint, last 2026-10-22T14:41:56.875Z, unchanged since 2026-10-22T14:41:56.875Z. 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 | `6` |
| Protocol version | `2025-06-18` |
| WWW-Authenticate on 401 | `not observed` |

| RFC 9728 protected resource metadata | `none` |
| Authorization servers | `none` |
| Legacy HTTP+SSE transport | `no` |
| Dynamic client registration | `not observed` |
| Client ID metadata documents | `not observed` |

- **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 6 tools that change things (6 write). Whether a call also works without credentials was not tested: tools are never called.

https://www.synapseconnexion.com/ia/mcp: tools/list returned 6 tools to an anonymous client, including confirme_page (write), confirme_domaine (write), confirme_courriel (write), confirme_battement (write), confirme_tache (write) and 1 more
