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

## Exfil surface

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

| Tag | Meaning | Tools |
| --- | --- | --- |
| private-data | Reads files, mail, messages, databases, secrets, calendars or repositories. | `mcp__l0g__get_document` |
| untrusted-input | Brings in text someone else can write: web pages, inbound email, messages, issues and comments. | `mcp__l0g__get_document` |
| outbound | Can carry data to people or systems: it sends, posts or publishes, or takes a recipient, channel or URL. | none |

## Findings

No check matched anything in these tool definitions.


## Changes things (2)

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

### `build_research_pack`

- 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
Compose en un appel un paquet de recherche déterministe : documents classés, claims canoniques, sources primaires, liens claim -> preuve, fraîcheur, Risk Diff, éléments adverses, limites et URLs citables. Ne produit aucune opinion d’investissement.
```

### `discover_l0g`

- 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
Point d’entrée compact : capacités, versions, fraîcheur, contrats, règles de preuve et chemins MCP complet/compact.
```

## Only reads (4)

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

### `get_document`

- The name "get_document" says "get": a word for reading.
- Tag private-data: The name "get_document" says "get" and "document": it reads documents.
- Tag untrusted-input: The description's first sentence says "url": it reads web pages, which anyone can write.

Description, as the server wrote it:

```untrusted-server-text
Lit un article ou guide l0g par slug, avec pagination opaque, troncature explicite, références et URL canonique.
```

### `get_evidence`

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

Description, as the server wrote it:

```untrusted-server-text
Interroge les claims et leurs sources, un sous-graphe de preuve ou le registre de sources avec une seule primitive compacte.
```

### `get_risk_state`

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

Description, as the server wrote it:

```untrusted-server-text
Produit agentique principal de l0g. Renvoie un contrat stable et sourcé pour l’état courant, le diff 1/7/30 jours, l’historique d’un instrument ou un replay Black Box point-in-time. Commencer ici pour toute question sur le risque.
```

### `search_l0g`

- The name "search_l0g" says "search": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Recherche filtrée bilingue dans articles, guides, glossaire, méthodologies et sources. Renvoie des URL canoniques et des extraits bornés.
```

## Claude Code permissions

For `.claude/settings.json`, assuming the server is installed as `l0g`:

```json
{
  "permissions": {
    "allow": [
      "mcp__l0g__search_l0g",
      "mcp__l0g__get_document",
      "mcp__l0g__get_evidence",
      "mcp__l0g__get_risk_state"
    ],
    "ask": [
      "mcp__l0g__discover_l0g",
      "mcp__l0g__build_research_pack"
    ],
    "deny": []
  }
}
```

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

- `mcp__l0g__get_document`: private-data, untrusted-input

## Remote posture

What an anonymous client saw at the remote endpoint, last 2026-10-22T14:57:07.782Z, unchanged since 2026-10-22T14:57:07.782Z. 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 | `2` |
| Protocol version | `2025-06-18` |
| WWW-Authenticate on 401 | `not observed` |
| resource_metadata in WWW-Authenticate | `none` |
| 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 2 tools that change things (2 write). Whether a call also works without credentials was not tested: tools are never called.

https://l0g.fr/api/mcp/compact: tools/list returned 6 tools to an anonymous client, including discover_l0g (write), build_research_pack (write)
```
