## 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 (1)

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

### `run_free_scan`

- The name "run_free_scan" says "run": a word for a change.

Description, as the server wrote it:

```untrusted-server-text
Free LLM agent security review in ~35s. Two parts: (1) 8 live adversarial probes (jailbreak / prompt injection / system-prompt extraction / tool abuse) against your agent spec, and (2) a deterministic static audit of which guardrails the spec text itself is missing. Returns a 0-100 risk score, per-finding evidence, and a paste-ready guardrail sentence for each gap.
```

## Only reads (4)

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

### `get_pricing`

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

Description, as the server wrote it:

```untrusted-server-text
PRO pricing & payment info: 44 probes / 20 attack classes / 0-100 score / CI gate / per-class remediation, 0.15 XNO (ERC-20 or Lightning) or card.
```

### `get_purchase_flow`

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

Description, as the server wrote it:

```untrusted-server-text
Machine-readable autonomous purchase procedure: how an agent pays (0.15 XNO, or USDC on Base via x402) and receives the PRO download with no human in the loop (callback push + poll fallback).
```

### `get_scan_result`

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

Description, as the server wrote it:

```untrusted-server-text
Poll a scan by job id (returned by run_free_scan) until status=done.
```

### `validate`

- The name "validate" says "validate": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Judge one delivery against the task's own acceptance rule and return {verdict: accepted|rejected, reason}. Called by the brick.blue hub when this seat is drawn as validator. Judges only machine-checkable criteria (json_schema / contains / fields); a task with no such rule is accepted, because rejecting needs evidence.
```

## Claude Code permissions

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

```json
{
  "permissions": {
    "allow": [
      "mcp__agent-security__get_scan_result",
      "mcp__agent-security__get_pricing",
      "mcp__agent-security__get_purchase_flow",
      "mcp__agent-security__validate"
    ],
    "ask": [
      "mcp__agent-security__run_free_scan"
    ],
    "deny": []
  }
}
```

## Remote posture

What an anonymous client saw at the remote endpoint, last 2026-11-04T02:19:22.620Z, unchanged since 2026-11-04T02:19:22.620Z. 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 | `1` |
| 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` |

| Dynamic client registration | `not observed` |
| Client ID metadata documents | `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 1 tool that changes things (1 write). Whether a call also works without credentials was not tested: tools are never called.

https://llmrt-companion.manhliemcn4euwlu.workers.dev/mcp-agent-security: tools/list returned 5 tools to an anonymous client, including run_free_scan (write)
