## Exfil surface

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

| Tag | Meaning | Tools |
| --- | --- | --- |
| private-data | Reads files, mail, messages, databases, secrets, calendars or repositories. | `mcp__turva__get_contact` `mcp__turva__get_security_evidence` |
| untrusted-input | Brings in text someone else can write: web pages, inbound email, messages, issues and comments. | `mcp__turva__get_contact` `mcp__turva__get_security_evidence` |
| 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.


## Only reads (5)

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

### `get_agent_readiness`

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

Description, as the server wrote it:

```untrusted-server-text
Returns turva.dev's own agent-readiness score from an independent public scanner (isitagentready.com), including category sub-scores, with the measurement date and a link to the scanner's start page, where a new check can be run (the link does not open the recorded reading). Use this when a user asks how turva.dev scores, whether its claims are verifiable, or what proof backs the audit service. For web-security scan results, which are a separate measurement, use get_security_evidence instead. Read-only: returns static JSON that is compiled into the Worker, so it changes nothing and updates only on deploy.
```

### `get_contact`

- The name "get_contact" says "get": a word for reading.
- Tag private-data: The name "get_contact" says "get" and "contact": it reads contacts. The description's first sentence says "return" and "email": it reads mail.
- Tag untrusted-input: The description's first sentence says "return" and "email": it reads inbound email, which other people can write.

Description, as the server wrote it:

```untrusted-server-text
Returns who runs turva.dev and the official ways to reach it: the operator and business details, the email address, the Signal link, the LinkedIn profile, the correspondence languages, the first-reply time and the access an audit needs. Use this when a user asks who is behind turva.dev, how to contact it, how to start an audit or what access has to be granted. For what is sold and what it costs use get_services instead. Read-only: returns static JSON that is compiled into the Worker, so it changes nothing and updates only on deploy.
```

### `get_principles`

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

Description, as the server wrote it:

```untrusted-server-text
Returns turva.dev's engagement principles: async-only, least access, the result shows up in scanner numbers, and open and verifiable. Use this when a user asks how turva.dev works with clients or what rules an engagement follows. For what is sold and what it costs use get_services instead, and for how to start use get_contact. Read-only: returns static JSON that is compiled into the Worker, so it changes nothing and updates only on deploy.
```

### `get_security_evidence`

- The name "get_security_evidence" says "get": a word for reading.
- Tag private-data: The description's first sentence says "return" and "mail": it reads mail.
- Tag untrusted-input: The description's first sentence says "return" and "web": it reads web pages, which anyone can write.

Description, as the server wrote it:

```untrusted-server-text
Returns the latest public web-security scan results for turva.dev's own domain (Hardenize, Internet.nl site and mail), each with its scan date. Use this when a user asks about turva.dev's own security posture or wants evidence beyond agent-readiness scores. For the agent-readiness score itself, which is a separate measurement, use get_agent_readiness instead. Read-only: returns static JSON that is compiled into the Worker, so it changes nothing and updates only on deploy.
```

### `get_services`

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

Description, as the server wrote it:

```untrusted-server-text
Returns turva.dev's service catalog: the Shopify agent storefront check, agent-readiness audit, advisory, implementation, agent operations, and MCP server design, plus the engagement model and pricing (fixed list prices for the Shopify agent storefront check, audit, advisory and implementation; agent operations and MCP server design on request), and two implementation add-ons that carry a fixed price and are sold only with the diagnosis they follow, bought with it, with its report, or after the report and before implementation starts. Use this when a user asks what turva.dev offers, what it costs, or how an engagement works. For how to reach turva.dev use get_contact instead, and for the rules an engagement follows use get_principles. Read-only: returns static JSON that is compiled into the Worker, so it changes nothing and updates only on deploy.
```

## Claude Code permissions

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

```json
{
  "permissions": {
    "allow": [
      "mcp__turva__get_services",
      "mcp__turva__get_agent_readiness",
      "mcp__turva__get_security_evidence",
      "mcp__turva__get_principles",
      "mcp__turva__get_contact"
    ],
    "ask": [],
    "deny": []
  }
}
```

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

- `mcp__turva__get_security_evidence`: private-data, untrusted-input
- `mcp__turva__get_contact`: private-data, untrusted-input
