## 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.

### `request_contact`

- The name "request_contact" says "request": a word for a change.
- The description's first verb is "send": a word for sending, and what is sent cannot be taken back.

Description, as the server wrote it:

```untrusted-server-text
Sends the person's question to Mike Olson, a licensed South Carolina real estate agent with eXp Realty, LLC. Only call this when the person asked you to. It never carries consent to calls or texts — Mike emails the person himself to confirm before anything else.
```

## Changes things (7)

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

### `estimate_range`

- 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
Arithmetic, not a price opinion: the middle half of closed-sale price per square foot (25th–75th percentile) for a complex, or for attached or detached homes island-wide, times the given heated square feet. For a real CMA, send the person to request_contact.
```

### `fees`

- 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
The fee ledger for Kiawah, Seabrook or Johns Island: each buyer, owner and rental charge with its amount, who charges it, how sure it is (confirmed / secondary / conflicting / not published), its source and the date it was checked.
```

### `flood_zone`

- 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 street address in Charleston County: FEMA's flood zone and base flood elevation at the point the Census geocoder places it, the map panel and its date, whether it is inside a town or the City of Charleston, the county tax district, and the ground's height from USGS lidar. Live calls to the government services named in sources. A geocoded point, not a survey — the person confirms on the parcel's elevation certificate.
```

### `happenings`

- 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
What's happening on the islands and across Charleston, as one list cut on the islands' clock: the Towns' and the library's calendars, the music venues' own feeds (the Charleston Pour House, the Royal American), the year's big dates, the special events, what venues posted and a person approved, and a weekly sweep of the venues with no feed. Every item carries its organizer's page; the door price is as the venue lists it. Use when = today, tomorrow, weekend, week (next 7 days) or all (next 3 weeks); tag = Music for live music.
```

### `island_market`

- 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
Kiawah, Seabrook or Johns Island: the last 12 months of residential sales island-wide from the MLS's own statistics (every island). Kiawah and Seabrook add home sales from 2021-01-01 to the last pull (2026-10-14), checked month by month against the MLS's own statistics: the last 12 months, each year's price per square foot and price-cut share, each price band's days on market and months of supply, and what cutting the price has meant for sellers.
```

### `places`

- 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
The island directory: 193 real places on Kiawah, Seabrook, Johns Island, Wadmalaw and the Charleston area — restaurants, coffee, groceries, golf, beaches and parks, charters, fishing, places to stay, vacation rentals, health care, pets, home services, home watch and the towns — each with what it is, its address, phone and website, from its own site. Listed, never ranked; no one pays to be here. Search by words, island or category.
```

### `true_cost`

- 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
The site's true-cost calculator: for a price on Kiawah, Seabrook or Johns Island, the buyer's closing costs, the first year of owning (property tax, association dues, base utilities), what comes later and the seller's side — each line from the fee ledger with how sure it is. An estimate from published fees, not a closing statement or tax advice.
```

## Only reads (2)

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

### `get_neighborhood`

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

Description, as the server wrote it:

```untrusted-server-text
One neighborhood's record. Kiawah and Seabrook: sourced facts (each with who published it), regime manager, the county's homes and lots, its MLS sales by year, the living-CMA price-per-square-foot range, what it costs to own (fee ledger lines) and the page URL.
```

### `list_neighborhoods`

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

Description, as the server wrote it:

```untrusted-server-text
Every neighborhood on Kiawah, Seabrook or Johns Island. Kiawah and Seabrook: every neighborhood and villa regime — type, area, regime manager, MLS sales since 2021 and the median price per square foot over the last 24 months where five or more sales allow. Facts about places only.
```
