## 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.


## Can't be undone (1)

Sends, pays, publishes or merges: once done, it cannot be taken back. Claude Code: ask.

### `refund_escrow`

- The name "refund_escrow" says "refund": a word that usually means money moves, which cannot be taken back.

Description, as the server wrote it:

```untrusted-server-text
Refund an OPEN/FUNDED/DISPUTED escrow to the payer (exactly-once).
    Refunding an OPEN escrow is a cancel.
```

## Changes things (4)

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

### `dispute_escrow`

- The description's first verb is "move": a word for a change.

Description, as the server wrote it:

```untrusted-server-text
Move a FUNDED escrow to DISPUTED. An arbiter (agent-arbitration-agent)
    then resolves it to release or refund.
```

### `fund_escrow`

- The description's first verb is "mark": a word for a change.

Description, as the server wrote it:

```untrusted-server-text
Mark an OPEN escrow as FUNDED (idempotent). payment_ref links the
    payment-rail transaction.
```

### `open_escrow`

- The name "open_escrow" says "open": a word for a change.

Description, as the server wrote it:

```untrusted-server-text
Open an escrow between payer and payee. amount_minor is a positive
    integer in minor units (cents). The platform fee is computed and FROZEN at
    open (ceil bps). Returns the escrow_id (state OPEN). RETRY-SAFE: pass
    open_ref=<your job id> and a replayed open returns the ORIGINAL escrow
    (duplicate=true) instead of minting another one (E10).
```

### `release_escrow`

- 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
Release a FUNDED/DISPUTED escrow to the payee (exactly-once — a repeat
    release returns the existing terminal record, never a double payout).
```

## Only reads (4)

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.
```

### `escrow_status`

- The name "escrow_status" says "status": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Current record for an escrow.
```

### `list_escrows`

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

Description, as the server wrote it:

```untrusted-server-text
List escrows, optionally filtered by state
    (OPEN|FUNDED|RELEASED|REFUNDED|DISPUTED).
```

### `verify_audit`

- The description's first verb is "validate": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Validate the tamper-evident audit hash chain for an escrow.
```

## Claude Code permissions

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

  "permissions": {
    "allow": [
      "mcp__agent-escrow__escrow_status",
      "mcp__agent-escrow__list_escrows",

      "mcp__agent-escrow__describe_agent"
    ],
    "ask": [
      "mcp__agent-escrow__open_escrow",
      "mcp__agent-escrow__fund_escrow",
      "mcp__agent-escrow__release_escrow",
      "mcp__agent-escrow__refund_escrow",
      "mcp__agent-escrow__dispute_escrow"

## Remote posture

What an anonymous client saw at the remote endpoint, last 2026-10-22T15:19:13.899Z, unchanged since 2026-10-22T15:19:13.899Z. 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` |

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

https://mcp.viridisconservation.com/escrow/mcp: tools/list returned 9 tools to an anonymous client, including refund_escrow (irreversible), open_escrow (write), fund_escrow (write), release_escrow (write), dispute_escrow (write)
