## 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__patent__find_patent_citations` |
| untrusted-input | Brings in text someone else can write: web pages, inbound email, messages, issues and comments. | `mcp__patent__find_patent_citations` `mcp__patent__get_patent` `mcp__patent__search_patents` `mcp__patent__search_prior_art` |
| 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 (4)

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

### `find_patent_citations`

- The name "find_patent_citations" says "find": a word for reading.
- Tag private-data: The description's first sentence says "list" and "document": it reads documents.
- 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
List documents cited by a US patent and documents that cite it, using USPTO grant references and USPTO office-action citations. The PatentsView citation graph is paused. Not legal advice.
```

### `get_patent`

- The name "get_patent" says "get": 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
Fetch one US patent's title, abstract, claims, status, family, and citations from USPTO. Missing text is omitted rather than filled in. Not legal advice.
```

### `search_patents`

- The name "search_patents" says "search": 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
Search public US patent records by keywords, claim language, CPC class, assignee, inventor, or grant date. Every number in the result was returned by USPTO. Not legal advice.
```

### `search_prior_art`

- The name "search_prior_art" says "search": 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
Turn an idea description into a public-patent search and return the closest records the offices actually returned, with Google Patents links. Ranking counts overlapping words. It is not a patentability opinion. Not legal advice.
```

## Claude Code permissions

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

```json
{
  "permissions": {
    "allow": [
      "mcp__patent__search_patents",
      "mcp__patent__get_patent",
      "mcp__patent__find_patent_citations",
      "mcp__patent__search_prior_art"
    ],
    "ask": [],
    "deny": []
  }
}
```

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

- `mcp__patent__search_patents`: untrusted-input
- `mcp__patent__get_patent`: untrusted-input
- `mcp__patent__find_patent_citations`: private-data, untrusted-input
- `mcp__patent__search_prior_art`: untrusted-input
