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

## Findings

- **warn** Annotations that disagree with the tool in `run_signal` ([annotation-conflict](https://anlyon.dev/methodology#annotation-conflict))

```untrusted-server-text
The server marks "run_signal" read-only (readOnlyHint: true), and its own name, description or input give the class "write".

annotations: {"readOnlyHint":true,"destructiveHint":false,"idempotentHint":true,"openWorldHint":true}; The name "run_signal" says "run": a word for a change.
```


## Changes things (3)

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

### `check_parcel`

- 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
One parcel's stored record and its checks: the county value, last sale, years held, lot, zoning line, water, outbuildings, the recorded signs an owner may sell, and (Colorado) every stored check such as tax delinquency, estate records, code cases, permits, wildfire and flood. Find it by shinnslist key, by street address (with ZIP when you have it), or by latitude and longitude.
```

### `run_signal`

- The name "run_signal" says "run": a word for a change.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.
- Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data.
- Findings: warn annotation-conflict

Description, as the server wrote it:

```untrusted-server-text
Run one proven signal adapter live at a point in Colorado or Virginia (see list_signals for the ids). Needs an API key (x-api-key; a free key from POST /api/keys) and counts against its daily quota; the aggregate tools above do not.
```

### `town_stats`

- 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
How many parcels shinnslist tracks in a county, town or ZIP, with the count behind each buyer's trade (wholesaler, flipper, STR investor, developer, cash investor, land, family compound, realtor) and the as-of date. Counts come from county records, never estimates.
```

## Only reads (4)

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

### `explain_grading`

- The name "explain_grading" says "explain": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
How shinnslist grades itself, in plain words: personas open only after a hand check against county records, signals proven only by a test against their live source, the daily ranking graded against what actually sells, and how close the value estimate comes to real sale prices (the buyer-price floor is the bar). Returns the current numbers and the page to cite.
```

### `find_parcels`

- The name "find_parcels" says "find": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Find off-market parcels in a Colorado or Virginia county, town or ZIP from county records: who is likely to sell and why. Pick a trade for a buyer's list: wholesaler (absentee owners, held 10+ years, bought for under half of today's value), flipper (dated homes next to updated sales), str_investor (mountain-town homes with absentee owners), developer (land is most of the value), cash_investor and brrr (rent against value), land (empty lots), two_households (a family compound: room for two households), realtor (estate, tax lien, code case or stalled permit). Returns parcels with address, county value, last sale, years held and a shinnslist link; never owner names.
```

### `list_coverage`

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

Description, as the server wrote it:

```untrusted-server-text
Which counties and cities shinnslist covers, how many parcels each holds, how fresh they are, which buyer's trades are open, and how many signals are proven. Call it first when unsure whether an area is covered.
```

### `list_signals`

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

Description, as the server wrote it:

```untrusted-server-text
The signals shinnslist has proven against their live public source, with the date, precision and recall of each proof. Only proven signals are listed; run one with run_signal. Nothing pending or planned appears here.
```

## Claude Code permissions
