## 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__crosodo__lookup_county` |
| untrusted-input | Brings in text someone else can write: web pages, inbound email, messages, issues and comments. | `mcp__crosodo__list_products` `mcp__crosodo__lookup_county` `mcp__crosodo__lookup_state_law` `mcp__crosodo__start_checkout` `mcp__crosodo__verify_certification` |
| outbound | Can carry data to people or systems: it sends, posts or publishes, or takes a recipient, channel or URL. | none |

```

- **info** The word "credentials" in `verify_certification` ([credentials-mention](https://anlyon.dev/methodology#credentials-mention))

```untrusted-server-text
The input schema at properties.certId.description mentions "Credential".

```


## Changes things (2)

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

### `start_checkout`

- The name "start_checkout" says "start": a word for a change.
- Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data.

Description, as the server wrote it:

```untrusted-server-text
Creates a Stripe Checkout session server-side and returns { checkoutUrl, product, sessionId }. Hand the URL to the user; payment completes on Stripe's hosted page. This never charges. product: permit_guide | certified_exam | unlimited_pass. permit_guide and unlimited_pass are county-specific (state + county required). Pass idempotencyKey so agent retries cannot double-create sessions.
```

### `verify_certification`

- 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.
- Findings: info credentials-mention, info credentials-mention, info credentials-mention

Description, as the server wrote it:

```untrusted-server-text
Public lookup of a Crosodo Certified credential (format CC-{ST}-{YY}-{XXXX}, e.g. CC-VA-26-1042). Returns public fields only (holder display name, dates, status). Unknown, expired, or revoked credentials return an error. No auth.
```

## Only reads (3)

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

### `list_products`

- The name "list_products" says "list": a word for reading.
- Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data.

Description, as the server wrote it:

```untrusted-server-text
The Menu Frame catalog: free state-law report ($0) plus agent checkout SKUs. The public site sells Cottage Pro ($15 one time, lifetime access) at /cottage-pro. Notes the reusable 50%-off promotion code. Does not create a checkout session.
```

### `lookup_county`

- The name "lookup_county" says "lookup": a word for reading.
- Tag private-data: The description's first sentence says "contact": it reads contacts.
- Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data.

Description, as the server wrote it:

```untrusted-server-text
County-level cottage-food requirements for a US state + county from Crosodo's structured county dataset (contacts, verification status, local URLs, state summaries). Unknown states or counties return an error — never invented data. Cottage food laws change. This summary is generated from Crosodo's hand-maintained dataset — it is not legal advice. Verify with your county before selling.
```

### `lookup_state_law`

- The name "lookup_state_law" says "lookup": a word for reading.
- Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data.

Description, as the server wrote it:

```untrusted-server-text
Cottage-food / home-bakery requirements for a US state from Crosodo's hand-maintained dataset: sales cap, registration, allowed products, statute, and agency links. Accepts a 2-letter abbrev (VA) or slug (virginia). Unknown states return an error — never invented data. Cottage food laws change. This summary is generated from Crosodo's hand-maintained dataset — it is not legal advice. Verify with your county before selling.
```

## Claude Code permissions

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

```json
{
  "permissions": {
    "allow": [
      "mcp__crosodo__lookup_state_law",
      "mcp__crosodo__lookup_county",
      "mcp__crosodo__list_products"
    ],
    "ask": [
      "mcp__crosodo__start_checkout",
      "mcp__crosodo__verify_certification"
    ],
    "deny": []
  }
}
```

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

- `mcp__crosodo__lookup_state_law`: untrusted-input
- `mcp__crosodo__lookup_county`: private-data, untrusted-input
- `mcp__crosodo__list_products`: untrusted-input
- `mcp__crosodo__start_checkout`: untrusted-input
- `mcp__crosodo__verify_certification`: untrusted-input
