## Exfil surface

No private-data -> untrusted-input -> outbound path in this server alone: no tool is tagged private-data or untrusted-input 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. | none |
| 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_wage_locations`

- 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.

Description, as the server wrote it:

```untrusted-server-text
Checks the binding minimum-wage rate for up to 50 US locations in one call (city/county rate when it applies, else state, else federal). Each location may be a place name ("Spokane, WA", "Texas", "TX") or a jurisdiction slug. A city with no rule of its own on file returns its state's rate with noLocalRule:true. An unmatched location returns found:false with a reason instead of being omitted. 113 known jurisdictions, e.g.: federal, alaska, alabama, arkansas.
```

## Only reads (5)

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

### `get_answer`

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

Description, as the server wrote it:

```untrusted-server-text

Known slugs (14): how-to-set-pay-ranges, what-should-we-pay-for-a-role, is-our-pay-competitive, how-to-tie-executive-pay-to-performance, executive-compensation-components, how-much-executive-pay-at-risk, business-case-for-changing-rewards, make-financial-case-for-compensation, ….
```

### `get_library_work`

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

Description, as the server wrote it:

```untrusted-server-text
Returns one compensation library work's bibliographic record and (when profiled) its thesis.
```

### `get_wage_jurisdiction`

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

Description, as the server wrote it:

```untrusted-server-text
Returns one tracked jurisdiction's current minimum-wage rate, effective date, validation status, and next scheduled step. 113 known jurisdictions, e.g.: federal, alaska, alabama, arkansas.
```

### `list_compensationprofessional_feeds`

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

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

Description, as the server wrote it:

```untrusted-server-text

```

- **warn** Tools that change things, listed to anyone ([unauth-remote-writes](https://anlyon.dev/methodology#unauth-remote-writes))

```untrusted-server-text
The endpoint served tools/list without credentials, and the list has 1 tool that changes things (1 write). Whether a call also works without credentials was not tested: tools are never called.

https://compensationprofessional.com/api/mcp: tools/list returned 6 tools to an anonymous client, including check_wage_locations (write)
