## Exfil surface

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

| 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__lightray__check_company` |
| 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.


## Changes things (1)

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

### `check_company`

- Nothing in its name or description says what it does, so it is counted as a write.
- 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
Use this when someone asks about a company or wants one checked. Give the company's name and, if known, its city or country. If a recent report on the company is stored, it comes back at once; otherwise a new report starts and the answer says when it will be ready. A new report uses one of the reader's reports; asking again for the same company does not. When several companies match the name, the answer lists them: ask the reader which one they mean, then call this again with that company's choice token. LightRay checks companies, not people.
```

## Only reads (2)

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

### `get_report`

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

Description, as the server wrote it:

```untrusted-server-text
Use this to see how far a report has got and what has been found so far, or to read a ready report: its date, the main point, any questions to ask, what was found, the next steps, the companies worth a look next and its link. LightRay writes each report: the main point, questions, findings and next steps are LightRay's. Give the report_id that check_company or list_reports returned, or the report's link. Reading a report uses none of the reader's reports.
```

### `list_reports`

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

Description, as the server wrote it:

```untrusted-server-text
Use this to see the reader's recent reports from here, newest first, each with whether it is ready and its link. It uses none of the reader's reports.
```

## Claude Code permissions

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

```json
{
  "permissions": {
    "allow": [
      "mcp__lightray__get_report",
      "mcp__lightray__list_reports"
    ],
    "ask": [
      "mcp__lightray__check_company"
    ],
    "deny": []
  }
}
```

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

- `mcp__lightray__check_company`: untrusted-input
