## 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.

### `coverage`

- 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 Vancouver streets, blocks and directory years AddressLore covers, with each street's page.
```

### `house_history`

- 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
When a covered Vancouver house was built and what stood there: the building permit (1901–1930) and the City's year built, what the 1912 fire insurance map draws on the lot and whether today's building is very likely that one, what stands today, and who lived there in each directory year with each listing's source page. Residents' names through 1945 only; later years show a household and job without names. Anything inferred is marked inferred.
```

## Only reads (1)

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

### `find_house`

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

Description, as the server wrote it:

```untrusted-server-text
Look up a Vancouver address, or a resident's surname from 1945 or earlier, in AddressLore's coverage. Returns the matching house's path for house_history, or says plainly that the address isn't covered (never a nearby house in its place), with the covered streets.
```

## Claude Code permissions

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

```json
{
  "permissions": {
    "allow": [
      "mcp__addresslore__find_house"
    ],
    "ask": [
      "mcp__addresslore__house_history",
      "mcp__addresslore__coverage"
    ],
    "deny": []
  }
}
```

- **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://addresslore.com/mcp: tools/list returned 3 tools to an anonymous client, including house_history (write), coverage (write)
