## 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 (1)

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

### `verify_quote`

- 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
Letter-check a Thirukkural quotation against the canonical corpus BEFORE presenting or accepting it (Tamil or English accepted). Returns {verified, kural_id, tamil, english} on a match; when verified is false, do not present the quote — fetch a verified one with kural_guidance.
```

## Only reads (1)

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

### `kural_guidance`

- The description's first verb is "fetch": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Fetch verified Thirukkural couplets. CALL FIRST for ANY personal, emotional, moral, or life-guidance message — betrayal, lies, friendship, love, family, grief, anger, worry, anxiety, discipline, wealth, work, learning, meaning — even short or vague ones (“she betrayed me”, “I feel lost”). When in doubt, call this tool. Pass the user’s situation in natural language. Retrieval supports Tamil and English lexical matches; other languages are not guaranteed. Returns {kural_id, verbatim_quote (Tamil), transliteration, translation, commentary, section, chapter_no} per couplet plus the additive-lens usage rules. Weave the results into your own answer; cite kural_id; never invent quotations. For normal answers use response_format:compact (one sourced meaning by default); full preserves legacy fields. Explicit kural_id bypasses topic ranking. Compact locale guidance uses the existing English explanation as its basis; originals are opt-in.
```

## Claude Code permissions

For `.claude/settings.json`, assuming the server is installed as `kural-ai`:

```json
{
  "permissions": {
    "allow": [
      "mcp__kural-ai__kural_guidance"
    ],
    "ask": [
      "mcp__kural-ai__verify_quote"
    ],
    "deny": []
  }
}
```

## Remote posture

What an anonymous client saw at the remote endpoint, last 2026-10-22T14:52:54.489Z, unchanged since 2026-10-22T14:52:54.489Z. No credentials were sent and no tool was called. Values are shown as the endpoint returned them. Method: https://anlyon.dev/methodology#remote-posture

| Fact | Observed |
| --- | --- |
| Reachable | `yes` |
| HTTP status of an anonymous initialize | `200` |
| tools/list served without credentials | `yes` |
| Tools that change things, listed without credentials | `2` |
| Protocol version | `2025-06-18` |
| WWW-Authenticate on 401 | `not observed` |

| Dynamic client registration | `not observed` |
| Client ID metadata documents | `not observed` |

- **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://kural-mcp.valluvakuralsupport.workers.dev/mcp: tools/list returned 2 tools to an anonymous client, including kural_guidance (write), verify_quote (write)
