## Exfil surface

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

| 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. | `mcp__muhabbit__muhabbit_record_verify` |

## Findings

- **info** The word "credentials" in `muhabbit_alerts` ([credentials-mention](https://anlyon.dev/methodology#credentials-mention))

```untrusted-server-text
The description mentions "credentials".

description: "...firmed, the default; that feed needs no credentials and returns at most 20. Otherwise paid:..."
```

- **info** The word "credentials" in `muhabbit_events` ([credentials-mention](https://anlyon.dev/methodology#credentials-mention))

```untrusted-server-text
The description mentions "credentials".

description: "...erts). Page with next_cursor. (Free: no credentials needed.)"
```

- **info** The word "credentials" in `muhabbit_record_head` ([credentials-mention](https://anlyon.dev/methodology#credentials-mention))

```untrusted-server-text
The description mentions "credentials".

description: "...ten. null on an empty record. (Free: no credentials needed.)"
```

- **info** The word "credentials" in `muhabbit_record_entries` ([credentials-mention](https://anlyon.dev/methodology#credentials-mention))

description: "...5 calls a minute per client. (Free: no credentials needed.)"
```

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

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

annotations: {"readOnlyHint":true,"openWorldHint":false}; The input addresses people (input.to): what it sends cannot be taken back.
```


## Can't be undone (1)

Sends, pays, publishes or merges: once done, it cannot be taken back. Claude Code: ask.

### `muhabbit_record_verify`

- The input addresses people (input.to): what it sends cannot be taken back.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.
- Tag outbound: The input takes a destination (input.to): what the tool writes goes there.
- Findings: info credentials-mention, warn annotation-conflict

Description, as the server wrote it:

```untrusted-server-text
Recompute the public record's hash chain server-side over [from, to], at most 1000 entries (no bounds: the latest 1000). Returns ok, checked and head_hash, or the first broken id and the reason (prev_hash_mismatch, hash_mismatch, endpoint_missing). Limited to 5 calls a minute per client. (Free: no credentials needed.)
```

## Changes things (15)

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

### `muhabbit_alert`

- 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 exchange security alert with its evidence signals, sources and timeline. Takes the id from muhabbit_alerts, or the article_id of an alert headline seen in muhabbit_events. A confirmed alert is free; an unconfirmed (suspected) one answers 403 alert_unconfirmed unless include_unconfirmed is true, which reads the paid route. (Free when include_unconfirmed is false, the default, and the alert is confirmed. Otherwise paid: x402 payment, or an API key or wallet token on a paid plan.)
```

### `muhabbit_alerts`

- 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.
- Findings: info credentials-mention

Description, as the server wrote it:

```untrusted-server-text
Exchange hack and drain alerts from Muhabbit's incident engine (large outflows to unlabelled wallets, withdrawal halts, security-researcher posts, exchange statements). One item per incident: tier (suspected = unconfirmed, confirmed), exchange, headline, USD at risk, assets, evidence signals and sources, a timeline with named clocks, and links to its hash-chained public record entries. Newest update first. Use for 'is an exchange being hacked right now?' or 'any exchange incidents since T?'. Informational, not advice. (Free when tier is confirmed, the default; that feed needs no credentials and returns at most 20. Otherwise paid: x402 payment, or an API key or wallet token on a paid plan.)
```

### `muhabbit_categories`

- 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.

```

### `muhabbit_confidence`

- 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.

```

### `muhabbit_cross_reference`

- 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.

Use when asked 'is this confirmed?' or 'who else is reporting this?' — multi-source validation of an article's claims with entity correlation. (Needs an API key or wallet token: X-API-Key or Authorization: Bearer.)
```

### `muhabbit_events`

- Nothing in its name or description says what it does, so it is counted as a write.

Description, as the server wrote it:

```untrusted-server-text
The public market-event feed: every headline Muhabbit's wire published, newest first. Each item is an entry of the hash-chained public record with three clocks in UTC ms (source_at = publisher, detected_at = our ingest, published_at = our publication), focus tags, a category and impact 0-100. Covers exchange listings, US CPI, jobs and Fed, crypto, macro and tech. Exchange security alert headlines appear here too (suspected ones start with 'Unconfirmed:'; their evidence is in muhabbit_alerts). Page with next_cursor. (Free: no credentials needed.)
```

### `muhabbit_narrative_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
Time series for ONE narrative (15-min captures of phase, velocity, article and source counts). Use after muhabbit_narratives to see how a story's lifecycle evolved — is it accelerating or rolling over? (Needs an API key or wallet token: X-API-Key or Authorization: Bearer.)
```

### `muhabbit_narratives`

- 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:

- Findings: info credentials-mention

Description, as the server wrote it:

```untrusted-server-text
Raw public record entries in chain order from an id: each entry's frozen fields, prev_hash and hash, for offline verification. hash = sha256 over the canonical JSON bytes followed by prev_hash; the exact recipe is in /public/events/{id}/proof. Page with next_from. (Free: no credentials needed.)
```

- Findings: info credentials-mention

Description, as the server wrote it:

```untrusted-server-text
Latest entry id and hash of Muhabbit's public record: an append-only sha256 hash chain (hash_v1) over every published event. Pin the head now; muhabbit_record_verify later proves nothing up to it was rewritten. null on an empty record. (Free: no credentials needed.)
```
