## 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__studio__request_contact` `mcp__studio__run_website_audit` |
| outbound | Can carry data to people or systems: it sends, posts or publishes, or takes a recipient, channel or URL. | `mcp__studio__request_contact` `mcp__studio__run_website_audit` |

## Findings

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

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

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


## Can't be undone (1)

Sends, pays, publishes or merges: once done, it cannot be taken back. Claude Code: ask.

### `request_contact`

- The name "request_contact" says "request": a word for a change.
- The description's first verb is "send": a word for sending, and what is sent cannot be taken back.
- Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data.
- Tag outbound: The input takes a destination (input.phone): what the tool writes goes there.

Description, as the server wrote it:

```untrusted-server-text
Sends a project inquiry or question to the Developh team on behalf of the person you are helping. Use it only when the person explicitly asked to contact Developh and gave you their own name and email; never invent or guess contact details, and show them the message before sending. They get a confirmation email, and the team usually replies by email within 2 to 8 business hours.
```

## Changes things (2)

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

### `run_website_audit`

- The name "run_website_audit" says "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
Runs a Google PageSpeed Insights audit of a public website on mobile: performance, accessibility, best-practices and SEO scores, Core Web Vitals, the issues that weigh most, missing security headers and page weight. Takes 20 to 90 seconds. Only public http(s) addresses.
```

### `studio_info`

- 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.

Description, as the server wrote it:

```untrusted-server-text
Facts about Developh, a design and development studio in Lisbon, Portugal: address, team, services, sectors with case studies, timelines, how projects are priced and how to get in touch.
```

## Only reads (1)

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

### `list_case_studies`

- The name "list_case_studies" says "list": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Published client work by Developh with links to each case study. Filter by sector (restaurants, tourism, clinics) or service (websites, online stores, branding, web apps) to get what was built in each case; with no filter, lists every published project.
```

## Claude Code permissions

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

```json
{
  "permissions": {
    "allow": [
      "mcp__studio__list_case_studies"
    ],
    "ask": [
      "mcp__studio__studio_info",
      "mcp__studio__run_website_audit",
      "mcp__studio__request_contact"
    ],
    "deny": []
  }
}
```

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

- `mcp__studio__run_website_audit`: untrusted-input, outbound
- `mcp__studio__request_contact`: untrusted-input, outbound
