## Exfil surface

No private-data -> untrusted-input -> outbound path in this server alone: no tool is tagged private-data.

| 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__tooltrace__tooltrace_extract` `mcp__tooltrace__tooltrace_links` `mcp__tooltrace__tooltrace_metadata` `mcp__tooltrace__tooltrace_schema` `mcp__tooltrace__tooltrace_seo_audit` `mcp__tooltrace__tooltrace_sitemap` `mcp__tooltrace__tooltrace_tech_stack` |
| outbound | Can carry data to people or systems: it sends, posts or publishes, or takes a recipient, channel or URL. | `mcp__tooltrace__tooltrace_extract` `mcp__tooltrace__tooltrace_links` `mcp__tooltrace__tooltrace_metadata` `mcp__tooltrace__tooltrace_schema` `mcp__tooltrace__tooltrace_seo_audit` `mcp__tooltrace__tooltrace_sitemap` `mcp__tooltrace__tooltrace_tech_stack` |

## Findings

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

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

annotations: {"readOnlyHint":true,"destructiveHint":false,"idempotentHint":true,"openWorldHint":true}; The name "tooltrace_links" says "link": a word for a change.
```

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

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

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


## Changes things (6)

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

### `tooltrace_extract`

- Nothing in its name or description says what it does, so it is counted as a write.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.
- Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data.
- Tag outbound: The input takes a URL (input.url): a request to a URL can carry data to whoever runs it.

Description, as the server wrote it:

```untrusted-server-text
Extract clean content from a webpage. Returns Markdown, plain text, metadata, links, JSON-LD schema, and content sections. Use this for scraping, RAG ingestion, or content analysis.
```

### `tooltrace_links`

- The name "tooltrace_links" says "link": a word for a change.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.
- Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data.
- Tag outbound: The input takes a URL (input.url): a request to a URL can carry data to whoever runs it.
- Findings: warn annotation-conflict

Description, as the server wrote it:

```untrusted-server-text
Extract all links from a webpage with anchor text, internal/external classification, and normalized URLs.
```

### `tooltrace_metadata`

- Nothing in its name or description says what it does, so it is counted as a write.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.
- Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data.
- Tag outbound: The input takes a URL (input.url): a request to a URL can carry data to whoever runs it.

Description, as the server wrote it:

```untrusted-server-text
Extract page metadata: title, description, canonical URL, author, publication date, favicon, Open Graph, and Twitter card fields. Lightweight alternative to full extraction.
```

### `tooltrace_schema`

- Nothing in its name or description says what it does, so it is counted as a write.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.
- Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data.
- Tag outbound: The input takes a URL (input.url): a request to a URL can carry data to whoever runs it.

Description, as the server wrote it:

```untrusted-server-text
Extract JSON-LD structured data from a webpage. Returns schema.org entities like Article, Product, Organization, FAQ, BreadcrumbList, etc.
```

### `tooltrace_seo_audit`

- The description's first verb is "run": a word for a change.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.
- Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data.
- Tag outbound: The input takes a URL (input.url): a request to a URL can carry data to whoever runs it.
- Findings: warn annotation-conflict

Description, as the server wrote it:

```untrusted-server-text
Run an SEO audit on a webpage. Returns a score (0-100), weighted checks for metadata, headings, images, canonical signals, robots directives, social tags, schema, and content length, with evidence and recommendations.
```

### `tooltrace_tech_stack`

- Nothing in its name or description says what it does, so it is counted as a write.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.
- Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data.
- Tag outbound: The input takes a URL (input.url): a request to a URL can carry data to whoever runs it.

Description, as the server wrote it:

```untrusted-server-text
Detect the technology stack of a website: CMS, frameworks, JavaScript libraries, analytics, CDN, hosting, fonts, security tools, and more. Returns categorized detections with confidence levels.
```

## Only reads (1)

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

### `tooltrace_sitemap`

- The description's first verb is "inspect": a word for reading.
- Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data. The description's first sentence says "inspect" and "website": it reads web pages, which anyone can write. 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
Inspect a website's sitemap. Discovers sitemap URLs, parses sitemap XML, and returns listed page URLs with last-modified dates and change frequencies.
```

## Claude Code permissions

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

```json
{
  "permissions": {
    "allow": [],
    "ask": [
      "mcp__tooltrace__tooltrace_extract",
      "mcp__tooltrace__tooltrace_metadata",
      "mcp__tooltrace__tooltrace_links",
      "mcp__tooltrace__tooltrace_schema",
      "mcp__tooltrace__tooltrace_seo_audit",
      "mcp__tooltrace__tooltrace_tech_stack",
      "mcp__tooltrace__tooltrace_sitemap"
    ],
    "deny": []
  }
}
```

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

- `mcp__tooltrace__tooltrace_extract`: untrusted-input, outbound
- `mcp__tooltrace__tooltrace_metadata`: untrusted-input, outbound
- `mcp__tooltrace__tooltrace_links`: untrusted-input, outbound
- `mcp__tooltrace__tooltrace_schema`: untrusted-input, outbound
- `mcp__tooltrace__tooltrace_seo_audit`: untrusted-input, outbound
- `mcp__tooltrace__tooltrace_tech_stack`: untrusted-input, outbound
- `mcp__tooltrace__tooltrace_sitemap`: untrusted-input, outbound

## Remote posture

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

https://mcp.tooltrace.io/mcp: tools/list returned 7 tools to an anonymous client, including tooltrace_extract (write), tooltrace_metadata (write), tooltrace_links (write), tooltrace_schema (write), tooltrace_seo_audit (write) and 1 more
