## Exfil surface

No private-data -> untrusted-input -> outbound path in this server alone: no tool is tagged outbound.

| Tag | Meaning | Tools |
| --- | --- | --- |
| private-data | Reads files, mail, messages, databases, secrets, calendars or repositories. | `mcp__familylore__get_reading` `mcp__familylore__read_letter` |
| untrusted-input | Brings in text someone else can write: web pages, inbound email, messages, issues and comments. | `mcp__familylore__read_letter` |
| 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 `real_letters` ([annotation-conflict](https://anlyon.dev/methodology#annotation-conflict))

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

annotations: {"readOnlyHint":true,"destructiveHint":false,"idempotentHint":true,"openWorldHint":false}; The input takes a statement or command to run (input.script), which can change anything it can reach.
```

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

```untrusted-server-text
The server marks "read_letter" as not read-only (readOnlyHint: false), and its words say it reads.

annotations: {"readOnlyHint":false,"destructiveHint":false,"idempotentHint":false,"openWorldHint":true}; The name "read_letter" says "read": a word for reading.
```


## Changes things (7)

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

### `ask_letter`

- 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
Ask FamilyLore a question about one page in the person's account: what a phrase meant then, who someone was, what the letter says about something. The answer comes with the letter's lines it rests on, or says that the letter doesn't say. Use it with a page id from read_letter, my_letters or get_reading, once the page has been read. Questions the reading already answers (who is named, what the translation says) need no call.
```

### `my_allowance`

- 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 pages the person's FamilyLore account has left to read: today for a free account, this month otherwise, and when more come. Reading a page in the chat uses the same allowance as on the site.
```

### `my_letters`

- 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 pages in the person's FamilyLore account, newest first: each letter's title, language, the date it was added, whether it has been read, and its page id. Use it when the person asks about letters they have read on FamilyLore; pass a page id to get_reading for that letter's reading.
```

### `read_letter`

- The name "read_letter" says "read": a word for reading.
- The server marks it as not read-only (readOnlyHint: false).
- Tag private-data: The description's first sentence says "read" and "document": it reads documents.
- 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
Read a photo of an old handwritten letter, postcard or document with FamilyLore: the transcription in its own script, a translation and notes on what it meant then. Use it when the person attaches a photo of a handwritten page and asks what it says. It reads pre-1918 Russian and Ukrainian cursive, German Kurrent and Sütterlin, and Yiddish. It needs the person's FamilyLore account and uses one page of the account's allowance. It starts the reading and answers at once with the page id; a reading takes about a minute and a half. If the photo can't be attached here, call it without one: it answers with a one-time link where the person sends the photo to FamilyLore, and the page id to pass to get_reading once they have.
```

### `real_letters`

- The input takes a statement or command to run (input.script), which can change anything it can reach.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.
- Findings: warn annotation-conflict

Description, as the server wrote it:

```untrusted-server-text
FamilyLore's shelf of 16 real handwritten letters from 1758 to 1943, each with FamilyLore's reading: the transcription in the original script, an English translation, and notes on what the letter meant at the time. Use this when someone wants to see a real historical letter: one written in a given script (such as Kurrent, Sütterlin or old Russian cursive), in a given language, from a period or near a year, or the full reading of one of these letters. Without a letter id it lists the matching letters; with one it returns that letter's reading. Do not use it to read a letter or photo the person has: these are fixed example letters only.
```

### `script_guide`

- 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
FamilyLore's guide to the 137 letters of five old handwriting styles: Russian cursive, German Kurrent, Sütterlin, Hebrew cursive, American cursive. For one letter: how it was written (its forms, with images), what to look for, the letters it is mistaken for and how to tell them apart, and printed copybook plates where FamilyLore has them. Use this when someone asks how a letter was written in one of these hands, what an old letter shape is, or why two letters look alike; give the letter as written ("ѣ", "G"), by its name ("yat") or as transliterated, and the hand if known. With only a hand it returns that hand's alphabet. Do not use it to read a letter or photo the person has: it explains the alphabets only.
```

### `upload_slot`

- The name "upload_slot" says "upload": a word for a change.

Description, as the server wrote it:

```untrusted-server-text
A one-time link where the person sends FamilyLore the photo of a page, for FamilyLore's card.
```

## Only reads (2)

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

### `get_reading`

- The name "get_reading" says "get": a word for reading.
- Tag private-data: The description's first sentence says "note": it reads notes.

Description, as the server wrote it:

```untrusted-server-text
The reading of a page in the person's FamilyLore account: the transcription in its own script with the words FamilyLore was unsure of marked, the translation, notes on what it meant, how sure the reading is, and the page's link. Use it with the page id read_letter answered, to show the reading once it is done or to see whether it is still being read.
```

### `reading_status`

- The name "reading_status" says "status": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Where a page's reading is, for FamilyLore's card while the page is read.
```

## Claude Code permissions

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

```json
{
  "permissions": {
    "allow": [
      "mcp__familylore__get_reading",
      "mcp__familylore__reading_status"
    ],
    "ask": [
      "mcp__familylore__real_letters",
      "mcp__familylore__script_guide",
      "mcp__familylore__read_letter",
      "mcp__familylore__my_letters",
      "mcp__familylore__ask_letter",
      "mcp__familylore__my_allowance",
      "mcp__familylore__upload_slot"
    ],
    "deny": []
  }
}
```

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

- `mcp__familylore__read_letter`: private-data, untrusted-input
- `mcp__familylore__get_reading`: private-data

```untrusted-server-text
The endpoint served tools/list without credentials, and the list has 7 tools that change things (7 write). Whether a call also works without credentials was not tested: tools are never called.

https://familylore.ai/mcp: tools/list returned 9 tools to an anonymous client, including real_letters (write), script_guide (write), read_letter (write), my_letters (write), ask_letter (write) and 2 more
