## 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__localschema__get_location` `mcp__localschema__list_locations` `mcp__localschema__run_health_check` `mcp__localschema__validate_page` |
| outbound | Can carry data to people or systems: it sends, posts or publishes, or takes a recipient, channel or URL. | `mcp__localschema__generate_schema` `mcp__localschema__validate_page` |

## Findings

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

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

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

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

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

annotations: {"readOnlyHint":true,"idempotentHint":true,"openWorldHint":false}; The name "validate_schema" says "validate": a word for reading.
```


## Changes things (5)

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

### `generate_schema`

- The name "generate_schema" says "generate": a word for a change.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.
- 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
Generate LocalBusiness JSON-LD (schema.org) from business details and validate it against Google's rich result rules. Returns the JSON-LD, a ready-to-paste <script> tag and issues to fix. No API key needed.
```

### `run_health_check`

- The name "run_health_check" says "run": 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
Run a schema health check for a saved location: validates its markup, scans its website for the embed and conflicting hard-coded schema, detects unpublished changes and records the result in the dashboard and client reports. Needs a LocalSchema Pro API key in the request headers.
```

### `save_client`

- The name "save_client" says "save": a word for a change.

Description, as the server wrote it:

```untrusted-server-text
Create a client (brand) or update one by client_id, and optionally turn its white-label health report link on or off. Needs a LocalSchema Pro API key in the request headers.
```

### `save_location`

- The name "save_location" says "save": a word for a change.

Description, as the server wrote it:

```untrusted-server-text
Save a business location to the LocalSchema account — create one, or update one by location_id (only the business fields you send change) — and optionally publish it to its hosted embed so the client's site updates without code changes. Needs a LocalSchema Pro API key in the request headers.
```

### `validate_schema`

- The name "validate_schema" says "validate": a word for reading.
- The input takes a statement or command to run (input.code), which can change anything it can reach.
- 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
Validate existing LocalBusiness structured data: paste JSON-LD, a <script type="application/ld+json"> tag or a whole HTML page. Reports errors, missing recommended fields and best-practice warnings. No API key needed.
```

## Only reads (6)

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

### `get_embed_snippet`

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

Description, as the server wrote it:

```untrusted-server-text
Get the install snippet and live status for a LocalSchema hosted embed key (loc_… for one location, org_… for a client with several). Paste the script tag once; published updates reach the site automatically.
```

### `get_location`

- The name "get_location" says "get": a word for reading.
- Tag untrusted-input: The description's first sentence says "get" and "issue": it reads issues, which other people can write.

Description, as the server wrote it:

```untrusted-server-text
Get one saved location: its business fields (in the same shape save_location accepts), the current JSON-LD, the published JSON-LD, validation issues and embed details. Needs a LocalSchema Pro API key in the request headers.
```

### `list_business_types`

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

Description, as the server wrote it:

```untrusted-server-text
List the schema.org LocalBusiness subtypes LocalSchema supports (Dentist, Plumber, Restaurant, …). Use the most specific one as businessType.
```

### `list_clients`

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

Description, as the server wrote it:

```untrusted-server-text
List the agency's clients (brands) with their location counts, client-wide embed script and white-label report link. Needs a LocalSchema Pro API key in the request headers.
```

### `list_locations`

- The name "list_locations" says "list": a word for reading.
- Tag untrusted-input: The description's first sentence says "list" and "website": it reads web pages, which anyone can write.

Description, as the server wrote it:

```untrusted-server-text
List the business locations saved in the LocalSchema account: publish state, hosted embed script, website and latest health check score. Needs a LocalSchema Pro API key in the request headers.
```

### `validate_page`

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

- Claude Code: ask, because it is tagged outbound.

Description, as the server wrote it:

```untrusted-server-text
Fetch a public web page and audit its structured data: every JSON-LD block and type, the LocalBusiness markup's errors and warnings, LocalSchema embeds on the page and concrete recommendations. No API key needed.
```

## Claude Code permissions

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

```json
{
  "permissions": {
    "allow": [
      "mcp__localschema__list_business_types",
      "mcp__localschema__get_embed_snippet",
      "mcp__localschema__list_clients",
      "mcp__localschema__list_locations",
      "mcp__localschema__get_location"
    ],
    "ask": [
      "mcp__localschema__generate_schema",
      "mcp__localschema__validate_schema",
      "mcp__localschema__validate_page",
      "mcp__localschema__save_client",
      "mcp__localschema__save_location",
      "mcp__localschema__run_health_check"
    ],
    "deny": []
  }
}
```

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

- `mcp__localschema__generate_schema`: outbound
- `mcp__localschema__validate_page`: untrusted-input, outbound
- `mcp__localschema__list_locations`: untrusted-input
- `mcp__localschema__get_location`: untrusted-input
