## Exfil surface

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

| 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. | none |

## Findings

No check matched anything in these tool definitions.


## Changes things (5)

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

### `file_case`

- 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
File a dispute over an escrow. Opens the evidence window. Parties must
    be distinct; amount is in minor currency units (cents).
```

### `rule`

- 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
Issue the deterministic ruling: allocates 100% of the disputed amount
    from evidence weights + trust scores, and emits an escrow instruction
    (release/refund). Exactly-once — re-ruling returns the existing ruling.
```

### `set_trust_scores`

- The name "set_trust_scores" says "set": a word for a change.

Description, as the server wrote it:

```untrusted-server-text
Attach trust-oracle reputation scores (party -> [0,1]) as ruling inputs.
```

### `submit_evidence`

- The name "submit_evidence" says "submit": a word for a change.

Description, as the server wrote it:

```untrusted-server-text
Submit evidence while the case is open. kind: delivery_proof (weight 3),
    log (2), or statement (1). Only the named parties may submit.
```

### `verify_ruling`

- 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
Recompute the ruling from its cited evidence + trust inputs and check
    it matches the stored allocation (machine-checkable justice).
```

## Only reads (3)

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

### `describe_agent`

- The name "describe_agent" says "describe": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Fleet-standard self-description.
```

### `get_case`

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

Description, as the server wrote it:

```untrusted-server-text
Fetch the full case record, including any ruling.
```

### `list_cases`

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

Description, as the server wrote it:

```untrusted-server-text
List cases, optionally filtered by state (FILED|EVIDENCE_OPEN|RULED).
```

## Claude Code permissions

For `.claude/settings.json`, assuming the server is installed as `agent-arbitration`:

```json
{
  "permissions": {
    "allow": [
      "mcp__agent-arbitration__get_case",
      "mcp__agent-arbitration__list_cases",
      "mcp__agent-arbitration__describe_agent"
    ],
    "ask": [
      "mcp__agent-arbitration__file_case",
      "mcp__agent-arbitration__submit_evidence",
      "mcp__agent-arbitration__set_trust_scores",
      "mcp__agent-arbitration__rule",
      "mcp__agent-arbitration__verify_ruling"
    ],
    "deny": []
  }
}

## Remote posture

What an anonymous client saw at the remote endpoint, last 2026-10-22T15:00:51.210Z, unchanged since 2026-10-22T15:00:51.210Z. 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 | `5` |
| Protocol version | `2025-06-18` |
| WWW-Authenticate on 401 | `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 5 tools that change things (5 write). Whether a call also works without credentials was not tested: tools are never called.

https://mcp.viridisconservation.com/arbitration/mcp: tools/list returned 8 tools to an anonymous client, including file_case (write), submit_evidence (write), set_trust_scores (write), rule (write), verify_ruling (write)
