## Exfil surface

6 private-data -> untrusted-input -> outbound paths in this server alone. Denying 1 outbound tool breaks every one: `mcp__openentity__openentity_card`.

| Tag | Meaning | Tools |
| --- | --- | --- |
| private-data | Reads files, mail, messages, databases, secrets, calendars or repositories. | `mcp__openentity__openentity_card` `mcp__openentity__openentity_resolve` `mcp__openentity__openentity_self` |
| untrusted-input | Brings in text someone else can write: web pages, inbound email, messages, issues and comments. | `mcp__openentity__openentity_card` `mcp__openentity__openentity_resolve` |
| outbound | Can carry data to people or systems: it sends, posts or publishes, or takes a recipient, channel or URL. | `mcp__openentity__openentity_card` |

| Private data | Untrusted input | Outbound |
| --- | --- | --- |
| `mcp__openentity__openentity_card` | `mcp__openentity__openentity_card` | `mcp__openentity__openentity_card` |
| `mcp__openentity__openentity_card` | `mcp__openentity__openentity_resolve` | `mcp__openentity__openentity_card` |

## 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.

### `openentity_withdraw`

- The name "openentity_withdraw" says "withdraw": a word that usually means money moves, which cannot be taken back.
- The description says "Irreversible".

Description, as the server wrote it:

```untrusted-server-text
Withdraw your Declaration (spec 6.3). Irreversible: the entity is marked withdrawn. Needs confirm=true and your private_key_jwk (used for this call only).
```

## Changes things (5)

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

### `openentity_adopt`

- 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
Adopt an Open Entity identity. custody=custodial: the server makes your key and returns it once. custody=self: pass public_key, get bytes to sign, then call again with the signatures.
```

### `openentity_export_key`

- 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
Export your key from registry custody (spec 10.6): the registry returns its kept copy once and deletes it. Needs confirm=true and your private_key_jwk (used for this call only).
```

### `openentity_present`

- 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
Prove you hold your EID to a verifier: sign its nonce and audience into a Presentation carrying your current attestations (spec 4.7).
```

### `openentity_record`

- 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
Append entries to your Development Record. Pass signed entries, or kind and payload plus your private_key_jwk to have the server build and sign one (the key is used for this call only).
```

### `openentity_verify`

- 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
Verify an entity by EID, or any signed Open Entity object, and report schema, signatures and log inclusion.
```

## Only reads (6)

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

### `openentity_card`

- The description's first verb is "read": a word for reading.
- Tag private-data: The description's first sentence says "read" and "document": it reads documents.
- Tag untrusted-input: The input takes a URL (input.url), and the tool reads it: it reads web pages, which anyone can write.
- Tag outbound: The input takes a URL (input.url): a request to a URL can carry data to whoever runs it.
- Claude Code: ask, because it is tagged outbound.

Description, as the server wrote it:

```untrusted-server-text
Read an entity's A2A Agent Card (or only its Open Entity AgentExtension block) built from its Entity Document.
```

### `openentity_find`

- The name "openentity_find" says "find": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Find entities by what they can do (capability), by name, or by bound alias type.
```

### `openentity_read`

- The name "openentity_read" says "read": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Read the Open Entity llms.txt, the OEIS-1 spec (or one section, e.g. 10.4) or the Declaration text.
```

### `openentity_resolve`

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

Description, as the server wrote it:

```untrusted-server-text
Resolve a DID (did:key, did:web, did:webvh, did:pkh, did:plc) to its DID document.
```

### `openentity_self`

- The description's first verb is "read": a word for reading.
- Tag private-data: The description's first sentence says "read" and "document": it reads documents.

Description, as the server wrote it:

```untrusted-server-text
Read your own Entity Document, Identity Anchor and last record entries.
```

### `openentity_stats`

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

Description, as the server wrote it:

```untrusted-server-text
Read public registry counts: entities by level, record entries, attestations, log size.
```

## Claude Code permissions

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

```json
{
  "permissions": {
    "allow": [
      "mcp__openentity__openentity_read",
      "mcp__openentity__openentity_self",
      "mcp__openentity__openentity_resolve",
      "mcp__openentity__openentity_find",
      "mcp__openentity__openentity_stats"
    ],
    "ask": [
      "mcp__openentity__openentity_adopt",
      "mcp__openentity__openentity_verify",
      "mcp__openentity__openentity_record",
      "mcp__openentity__openentity_withdraw",
      "mcp__openentity__openentity_present",
      "mcp__openentity__openentity_export_key",
      "mcp__openentity__openentity_card"
    ],
    "deny": []
  }
}
```

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

- `mcp__openentity__openentity_self`: private-data
- `mcp__openentity__openentity_resolve`: private-data, untrusted-input
- `mcp__openentity__openentity_card`: private-data, untrusted-input, outbound

## Remote posture

What an anonymous client saw at the remote endpoint, last 2026-10-26T18:19:31.620Z, unchanged since 2026-10-26T18:19:31.620Z. 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` |
| 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` |

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

https://mcp.openentity.org/mcp: tools/list returned 11 tools to an anonymous client, including openentity_withdraw (irreversible), openentity_adopt (write), openentity_verify (write), openentity_record (write), openentity_present (write) and 1 more
