## Only reads (3)

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

### `fetch`

- The name "fetch" says "fetch": a word for reading.
- Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data.

Description, as the server wrote it:

```untrusted-server-text
Get one building’s record from Umarelli: building permits, assessed value and property tax bill, tax breaks, zoning, and news coverage. The id is a New York City BBL (ten digits), a Jersey City id such as jc:14106:39, or an Umarelli building URL.
```

### `recent_permits`

- The description's first verb is "list": a word for reading.
- Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data. The description's first sentence says "list" and "issue": it reads issues, which other people can write.

Description, as the server wrote it:

```untrusted-server-text
List new-building and major-renovation permits near a street address in New York City (dated by filing) or Jersey City (dated by issue), newest first, each with a link to its building on Umarelli.
```

### `search`

- The name "search" says "search": a word for reading.
- Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data.

Description, as the server wrote it:

```untrusted-server-text
Find buildings in New York City or Jersey City by street address. Returns ids, names and Umarelli page URLs; pass an id to fetch for the full record. New York City is assumed; include "Jersey City" to search there.
```

## Claude Code permissions

For `.claude/settings.json`, assuming the server is installed as `umarelli`:

```json
{
  "permissions": {
    "allow": [
      "mcp__umarelli__search",
      "mcp__umarelli__fetch",
      "mcp__umarelli__recent_permits"
    ],
    "ask": [],
    "deny": []
  }
}
```

Capability tags behind the rules (a read tagged outbound is asked about):

- `mcp__umarelli__search`: untrusted-input
- `mcp__umarelli__fetch`: untrusted-input
- `mcp__umarelli__recent_permits`: untrusted-input
