## 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 (2)

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

### `bank_cre_exposure`

- 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
Quarterly credit quality of U.S. bank commercial real estate loans: the Federal Reserve's seasonally adjusted delinquency and net charge-off rates (all commercial banks, CRE excluding farmland, up to 12 quarters) and FDIC call-report noncurrent rates split into nonresidential, multifamily and construction and land loans (up to 5 quarters), with quarter-over-quarter changes and the dollar size of the book.
```

### `rate_series`

- 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
Latest value, observation date, week-ago and month-ago readings and freshness status for 1 to 8 rate series (Treasury par curve 1-month to 30-year, SOFR and its 30/90/180-day averages, effective Fed funds, bank prime, Freddie Mac 30- and 15-year mortgage), read from the publishers' feeds the site refreshes daily. Optionally adds up to 365 days of daily history.
```

## Only reads (1)

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

### `market_snapshot`

- The name "market_snapshot" says "snapshot": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
The commercialproperty.today dashboard as data: 2- and 10-year Treasury, SOFR, 30-year mortgage and the Fed funds target; bank CRE delinquency, charge-off and noncurrent rates; KBRA CMBS delinquency and issuance; Green Street property prices, CBRE cap-rate direction and CMBS-implied cap rates; MBA originations, CBRE loan spreads and Fed lending standards. Each figure comes with its period, release date, stale flag and source link. Pick one section or all.
```

- **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 2 tools that change things (2 write). Whether a call also works without credentials was not tested: tools are never called.

https://commercialproperty.today/mcp: tools/list returned 3 tools to an anonymous client, including bank_cre_exposure (write), rate_series (write)
