Title and description, as the publisher wrote them:

```untrusted-server-text
PreClick — An MCP-native URL preflight scanning service for autonomous agents (formerly URLCheck).
PreClick scans links for threats and confirms intent match with high accuracy before agents click.

## Findings

- **warn** Annotations that disagree with the tool in `url_scanner_async_scan` ([annotation-conflict](https://anlyon.dev/methodology#annotation-conflict))

```untrusted-server-text
The server marks "url_scanner_async_scan" read-only (readOnlyHint: true), and its own name, description or input give the class "write".

annotations: {"readOnlyHint":true,"destructiveHint":false,"openWorldHint":true}; The description's first verb is "submit": a word for a change.
```

- **warn** Annotations that disagree with the tool in `url_scanner_async_scan_with_intent` ([annotation-conflict](https://anlyon.dev/methodology#annotation-conflict))

```untrusted-server-text
The server marks "url_scanner_async_scan_with_intent" read-only (readOnlyHint: true), and its own name, description or input give the class "write".

annotations: {"readOnlyHint":true,"destructiveHint":false,"openWorldHint":true}; The description's first verb is "submit": a word for a change.
```


## Changes things (2)

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

### `url_scanner_async_scan`

- The description's first verb is "submit": a word for a change.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.
- Findings: warn annotation-conflict

Description, as the server wrote it:

```untrusted-server-text
Submit a URL for asynchronous security analysis. Returns immediately with a task_id. Poll with url_scanner_async_task_status to check progress, then url_scanner_async_task_result to get the scan result. Async counterpart of url_scanner_scan for clients without native MCP Tasks support.
```

### `url_scanner_async_scan_with_intent`

- The description's first verb is "submit": a word for a change.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.
- Findings: warn annotation-conflict

Description, as the server wrote it:

```untrusted-server-text
Submit a URL with optional user intent for asynchronous security analysis. Returns immediately with a task_id. Poll with url_scanner_async_task_status to check progress, then url_scanner_async_task_result to get the scan result. Async counterpart of url_scanner_scan_with_intent for clients without native MCP Tasks support.
```

## Only reads (4)

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

### `url_scanner_async_task_result`

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

Description, as the server wrote it:

```untrusted-server-text
Retrieve the result of an asynchronous scan task. If completed, returns the full scan result (risk_score, confidence, agent_access_directive, etc.). If still running, returns status with retry_after_ms — call again after that interval. Non-blocking.
```

### `url_scanner_async_task_status`

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

Description, as the server wrote it:

```untrusted-server-text
Check the status of an asynchronous scan task. Returns the current task status using native MCP task semantics (working, completed, failed, cancelled) without blocking. Use url_scanner_async_task_result to retrieve the result once completed.
```

### `url_scanner_scan`

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

Description, as the server wrote it:

```untrusted-server-text
Analyze a URL for security threats (synchronous, blocks until complete or timeout). Returns risk score, confidence, agent access guidance, and intent_alignment (always not_provided for this tool; use url_scanner_scan_with_intent for intent context). For long-running scans, prefer url_scanner_async_scan which returns immediately with a task_id for polling via url_scanner_async_task_result.
```

### `url_scanner_scan_with_intent`

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

Description, as the server wrote it:

```untrusted-server-text
Analyze a URL for security threats with optional user intent context (synchronous, blocks until complete or timeout). Returns risk score, confidence, agent access guidance, and intent_alignment. For long-running scans, prefer url_scanner_async_scan_with_intent which returns immediately with a task_id for polling via url_scanner_async_task_result.
```

## Claude Code permissions

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

```json
{
  "permissions": {
    "allow": [
      "mcp__urlcheck__url_scanner_async_task_result",
      "mcp__urlcheck__url_scanner_async_task_status",
      "mcp__urlcheck__url_scanner_scan",
      "mcp__urlcheck__url_scanner_scan_with_intent"
    ],
    "ask": [
      "mcp__urlcheck__url_scanner_async_scan",
      "mcp__urlcheck__url_scanner_async_scan_with_intent"
    ],
    "deny": []
  }
}
