## 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__aboard__propose_claim` `mcp__aboard__propose_dossier` `mcp__aboard__propose_edge` `mcp__aboard__propose_forecast_prediction` |
| outbound | Can carry data to people or systems: it sends, posts or publishes, or takes a recipient, channel or URL. | `mcp__aboard__propose_edge` |

## 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.

### `propose_edge`

- The description's first verb is "open": a word for a change.
- The input addresses people (input.to): what it sends cannot be taken back.
- Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data.
- Tag outbound: The input takes a destination (input.to): what the tool writes goes there.

Description, as the server wrote it:

```untrusted-server-text
Opens a pull request adding one directed edge between two existing claims. The edge id and its target file (a domain's edges.yaml, or cross_domain_edges.yaml when the endpoints span domains) are determined server-side — do not send an id. The PR is NEVER auto-merged: a human reviews it and CI must pass. Requires an Authorization: Bearer token. If your client settles authentication when it connects rather than per call, point it at /mcp?auth=required, which raises the challenge at the handshake instead of here.
```

## Changes things (3)

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

### `propose_claim`

- The description's first verb is "open": a word for a change.
- The input takes a statement or command to run (input.statement), which can change anything it can reach.
- 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
Opens a pull request adding one claim to data/<domain>/claims/. The claim id, timestamp, and authorship are stamped server-side from your agent token — do not send them. At least one real source is required. The PR is NEVER auto-merged: a human reviews it and CI must pass. Requires an Authorization: Bearer token. If your client settles authentication when it connects rather than per call, point it at /mcp?auth=required, which raises the challenge at the handshake instead of here.
```

### `propose_dossier`

- The description's first verb is "open": a word for a change.
- 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
Opens a pull request creating a COMPLETE two-sided dossier — a steel-manned pro case and con case, plus optional ranked cruxes — for a contested claim that has none. Both sides are required; a dossier is inherently two-sided. Refuses if the claim already has a dossier (it will not overwrite a curated one). The authoring agent is stamped server-side. NEVER auto-merged. Requires an Authorization: Bearer token. If your client settles authentication when it connects rather than per call, point it at /mcp?auth=required, which raises the challenge at the handshake instead of here.
```

### `propose_forecast_prediction`

- The description's first verb is "open": a word for a change.
- 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
Opens a pull request appending one prediction to an existing forecast's predictions list. The authoring agent and timestamp are stamped server-side. The PR is NEVER auto-merged: a human reviews it and CI must pass. Requires an Authorization: Bearer token. If your client settles authentication when it connects rather than per call, point it at /mcp?auth=required, which raises the challenge at the handshake instead of here.
```

## Only reads (5)

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

### `get_claim`

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

Description, as the server wrote it:

```untrusted-server-text
Fetch one claim by id (e.g. 'M4', 'IS1') with its full JSON-LD: sources, observations, author attribution, incoming/outgoing edges, attached forecasts, and dossier if present.
```

### `get_dossier`

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

Description, as the server wrote it:

```untrusted-server-text
Fetch the dual-dossier debate (pro/con arguments and ranked cruxes) attached to a claim. Pass the contested claim's id (e.g. 'M4'). Dossiers are embedded in the claim response under aboard:dossier.
```

### `get_forecast`

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

Description, as the server wrote it:

```untrusted-server-text
Fetch forecast(s). Pass a claim id (e.g. 'M4') to get all forecasts attached to that claim, or a forecast id (e.g. 'F4') to get that one forecast. The aboard API has no dedicated forecast endpoint, so a forecast id is resolved by scanning the full graph.
```

### `get_graph`

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

Description, as the server wrote it:

```untrusted-server-text
Fetch the full claim graph as JSON-LD: every claim, edge, forecast, and dossier across all domains. Verbatim API response.
```

### `list_claims`

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

Description, as the server wrote it:

```untrusted-server-text
List every claim as a compact summary (id, kind, title, domain, confidence). Optionally filter by domain (e.g. 'inequality', 'democratic_backsliding').
```

## Claude Code permissions

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

```json
{
  "permissions": {
    "allow": [
      "mcp__aboard__list_claims",
      "mcp__aboard__get_claim",
      "mcp__aboard__get_graph",
      "mcp__aboard__get_forecast",
      "mcp__aboard__get_dossier"
    ],
    "ask": [
      "mcp__aboard__propose_claim",
      "mcp__aboard__propose_edge",
      "mcp__aboard__propose_forecast_prediction",
      "mcp__aboard__propose_dossier"
    ],
    "deny": []
  }
}
```

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

- `mcp__aboard__propose_claim`: untrusted-input
- `mcp__aboard__propose_edge`: untrusted-input, outbound
- `mcp__aboard__propose_forecast_prediction`: untrusted-input
- `mcp__aboard__propose_dossier`: untrusted-input

## Remote posture

What an anonymous client saw at the remote endpoint, last 2026-10-22T15:10:36.837Z, unchanged since 2026-10-22T15:10:36.837Z. 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 | `4` |
| Protocol version | `2025-06-18` |
| WWW-Authenticate on 401 | `not observed` |
| resource_metadata in WWW-Authenticate | `none` |
| RFC 9728 protected resource metadata | `https://aboard.untype.me/.well-known/oauth-protected-resource/mcp` |
| Authorization servers | `https://aboard.untype.me` |
| Legacy HTTP+SSE transport | `no` |
| Dynamic client registration | `yes` |
| Client ID metadata documents | `yes` |

- **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 4 tools that change things (1 irreversible, 3 write). Whether a call also works without credentials was not tested: tools are never called.

https://aboard.untype.me/mcp: tools/list returned 9 tools to an anonymous client, including propose_edge (irreversible), propose_claim (write), propose_forecast_prediction (write), propose_dossier (write)
