## Exfil surface

No private-data -> untrusted-input -> outbound path in this server alone: no tool is tagged private-data 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. | `mcp__world-data__get_catalog` |
| outbound | Can carry data to people or systems: it sends, posts or publishes, or takes a recipient, channel or URL. | none |

## Findings

- **info** The word "credentials" in `create_result_reference` ([credentials-mention](https://anlyon.dev/methodology#credentials-mention))

```untrusted-server-text
The description mentions "credential".

description: "...d to read one owned result with its own credential. Returns a credential-free, expiring re..."
```

- **info** The word "credentials" in `create_result_reference` ([credentials-mention](https://anlyon.dev/methodology#credentials-mention))

```untrusted-server-text
The input schema at properties.ttl_seconds.description mentions "credentials".

inputSchema.properties.ttl_seconds.description: "...also bounded by the job and both access credentials' expiry."
```

- **info** The word "credentials" in `get_catalog` ([credentials-mention](https://anlyon.dev/methodology#credentials-mention))

```untrusted-server-text
The description mentions "credential".

description: "...on and HTTP discovery routes. No access credential required."
```

- **info** The word "credentials" in `resolve_capability` ([credentials-mention](https://anlyon.dev/methodology#credentials-mention))

```untrusted-server-text
The input schema at properties.service_id.description mentions "credential".

inputSchema.properties.service_id.description: "...at most 96 UTF-8 bytes. Never a URL or credential."
```


## Deletes or cancels (2)

Removes, cancels or revokes something. Claude Code: deny.

### `delete_job`

- The name "delete_job" says "delete": a word for removing or ending something.
- The server marks it destructive (destructiveHint: true).

Description, as the server wrote it:

```untrusted-server-text
Delete the owner's stored result content. Retains an idempotency tombstone until expiry and does not reset quotas. Configure the owner's bearer access header.
```

### `revoke_result_reference`

- The name "revoke_result_reference" says "revoke": a word for removing or ending something.
- The server marks it destructive (destructiveHint: true).

Description, as the server wrote it:

```untrusted-server-text
Owner revokes future retrieval through one shared result reference. Repeating this action is safe; previously downloaded copies cannot be recalled.
```

## Changes things (3)

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

### `create_result_reference`

- The name "create_result_reference" says "create": a word for a change.
- Findings: info credentials-mention, info credentials-mention

Description, as the server wrote it:

```untrusted-server-text
Authorize one recipient client_id to read one owned result with its own credential. Returns a credential-free, expiring reference for agent handoff. Owner access stays in the configured header. Requires explicit intended recipient; no permission to other jobs, deletion or resharing.
```

### `submit_audit`

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

Description, as the server wrote it:

```untrusted-server-text
Audit bounded CSV against caller-supplied expected records with explicit grouping, exact source references, lineage and integrity checks. A completed audit can report mismatches or blocked parsing. Inspect result.status, comparison, ambiguities and unsupported rules. No factual verification or inferred transformations.
```

### `submit_csv`

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

Description, as the server wrote it:

```untrusted-server-text
Normalize bounded CSV using explicit column rules. Returns a complete private job and checked CSV. Configure bearer access in the client header. Reuse request_key on retries.
```

## Only reads (5)

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

### `get_catalog`

- The name "get_catalog" says "get": a word for reading.
- Tag untrusted-input: The description's first sentence says "read" and "http": it reads web pages, which anyone can write.
- Findings: info credentials-mention

Description, as the server wrote it:

```untrusted-server-text
Read public capabilities, free allowances, access bootstrap, privacy, retention and HTTP discovery routes. No access credential required.
```

### `get_job`

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

Description, as the server wrote it:

```untrusted-server-text
Recover the original complete private CSV or audit result using its job_id and the owner's bearer access header. Results expire within 24 hours and cannot outlive access.
```

### `get_result_reference`

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

Description, as the server wrote it:

```untrusted-server-text
Retrieve the full shared result using the nominated recipient's configured bearer header. The reference alone grants no access. Expired, revoked or deleted results are unavailable.
```

### `resolve_capability`

- The name "resolve_capability" says "resolve": a word for reading.
- Findings: info credentials-mention

Description, as the server wrote it:

```untrusted-server-text
Resolve an exact canonical Wever service_id to its maintained connection metadata, contract, limits and access steps. Unknown identities are rejected; no caller-supplied URL is fetched. Does not verify live availability or authorize execution.
```

### `search_capabilities`

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

Description, as the server wrote it:

```untrusted-server-text
Find maintained Wever capabilities by a short task description or keyword. Returns fixed known services with connection details, contracts, limits and access steps. Does not execute work, grant permissions, search the whole web, or verify live availability.
```

## Claude Code permissions

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

```json
{
  "permissions": {
    "allow": [
      "mcp__world-data__get_catalog",
      "mcp__world-data__get_job",
      "mcp__world-data__get_result_reference",
      "mcp__world-data__resolve_capability",
      "mcp__world-data__search_capabilities"
    ],
    "ask": [
      "mcp__world-data__create_result_reference",
      "mcp__world-data__submit_audit",
      "mcp__world-data__submit_csv"
    ],
    "deny": [
      "mcp__world-data__delete_job",
      "mcp__world-data__revoke_result_reference"
    ]
  }
}
```

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

- `mcp__world-data__get_catalog`: untrusted-input

## Remote posture

What an anonymous client saw at the remote endpoint, last 2026-10-22T15:17:06.543Z, unchanged since 2026-10-22T15:17:06.543Z. 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 | `2025-11-25` |
| 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 5 tools that change things (2 destructive, 3 write). Whether a call also works without credentials was not tested: tools are never called.

https://wever-world-data.quiet-salad-e96e.workers.dev/mcp: tools/list returned 10 tools to an anonymous client, including delete_job (destructive), revoke_result_reference (destructive), create_result_reference (write), submit_audit (write), submit_csv (write)
