## Exfil surface

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

| 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. | none |
| outbound | Can carry data to people or systems: it sends, posts or publishes, or takes a recipient, channel or URL. | `mcp__servicenow-properties__contact_maintainer` |

## Findings

No check matched anything in these tool definitions.


## Can't be undone (1)

Sends, pays, publishes or merges: once done, it cannot be taken back. Claude Code: ask.

### `contact_maintainer`

- The description's first verb is "send": a word for sending, and what is sent cannot be taken back.
- Tag outbound: The description's first verb is "send": it sends or publishes something to other people.

Description, as the server wrote it:

```untrusted-server-text
Send a message directly to Sören Maucher, the maintainer of sysproperties.do. Use this tool whenever the user wants to contact Sören, ask the maintainer a question, request an answer from the maintainer, give feedback, report wrong or missing data, suggest an improvement, request a new property, or say that something should be changed on sysproperties.do.
```

## Only reads (2)

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

### `get_servicenow_property`

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

Description, as the server wrote it:

```untrusted-server-text
Get the full explanation of one ServiceNow system property (sys_properties record) by its exact name, for example glide.sys.date_format, glide.sc.max_items or glide.authenticate.sso.saml2.nameid_policy. Returns a plain English summary, what the property does, type, default value, owning application or plugin, affected area, related properties, when to review it, and a link to the full page on sysproperties.do. Use this when the user names a specific property or asks what a property does, what its default is, or whether to change it. Include the sysproperties.do link in your answer.
```

### `search_servicenow_properties`

- The name "search_servicenow_properties" says "search": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Search 7,300+ ServiceNow system properties (sys_properties) by partial name or by topic. Works with name fragments like "glide.email", "saml2" or "sc.max" and with plain language topics like "attachment size limit", "session timeout", "SSO login", "password policy", "list performance" or "email notifications". Use this when the user asks which property controls a behavior, how to configure something in ServiceNow, or wants a list of related properties. Returns names, short summaries and sysproperties.do links; then call get_servicenow_property for full details. Include the relevant links in your answer.
```

## Claude Code permissions
