## 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__streamlivr__public_posts` |

## Findings

- **warn** Base64 strings in `creator_listings` ([base64-blob](https://anlyon.dev/methodology#base64-blob))

```untrusted-server-text
The input schema at properties.cursor.examples[0] contains a 47-character base64 string. It decodes to text: "{"id":"cmmggbtik0000qrqbzontvsy38"}".

inputSchema.properties.cursor.examples[0]: "eyJpZCI6ImNtbWdnYnRpazAwMDBxcnFiem9udHZzeTM4In0"
```

- **warn** Base64 strings in `public_posts` ([base64-blob](https://anlyon.dev/methodology#base64-blob))

```untrusted-server-text
The input schema at properties.cursor.examples[0] contains a 47-character base64 string. It decodes to text: "{"id":"cmmggbtik0000qrqbzontvsy38"}".

inputSchema.properties.cursor.examples[0]: "eyJpZCI6ImNtbWdnYnRpazAwMDBxcnFiem9udHZzeTM4In0"
```

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

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

annotations: {"readOnlyHint":true,"destructiveHint":false,"idempotentHint":false,"openWorldHint":false}; The name "public_posts" says "post": a word for a change.
```

- **warn** Base64 strings in `music_catalog` ([base64-blob](https://anlyon.dev/methodology#base64-blob))

```untrusted-server-text
The input schema at properties.cursor.examples[0] contains a 47-character base64 string. It decodes to text: "{"id":"cmmggbtik0000qrqbzontvsy38"}".

## Changes things (4)

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

### `creator_listings`

- 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: warn base64-blob

Description, as the server wrote it:

```untrusted-server-text
Public creator and brand profiles: name, bio, avatar, country, follower counts, verification and account age. Searchable by name, bio, hashtag and country with ?q=. Combine with ?limit=, ?verified=, ?minFollowers= and ?sort=followers|newest. The response includes the total and nextCursor. Priced per creator credited. One cent in USDC per creator credited, with a one cent minimum per request. A page that credits 50 creators costs $0.50. The 402 invoice carries the exact amount before anything is signed. Paid route: USDC 0.01 per creator credited, one cent minimum and 2 maximum, settled over x402 on Celo. Without a payment the call returns the x402 payment requirements instead of data, and the requirements carry the exact amount for the call that was asked for.
```

### `creator_profile`

- 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 public creator or brand profile by id, with the counts of their published content and catalogued tracks. One creator, so one cent, which is the cheapest way to buy when the agent already knows which profile it needs. Paid route: USDC 0.01 per request, settled over x402 on Celo. Without a payment the call returns the x402 payment requirements instead of data, and the requirements carry the exact amount for the call that was asked for.
```

### `music_catalog`

- 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: warn base64-blob

Description, as the server wrote it:

```untrusted-server-text
Music and audio metadata for African and global repertoire: title, artist, ISRC, artwork, and a playable preview clip when the source provides one. Each row carries a "label" block that names its owner and how many public posts draw on it, and an "attribution" note. A recording is credited to the artist who owns it, never to the accounts whose posts used it; a recording with no Streamlivr owner is retained by the platform. Searchable by title or artist with ?q= and paginated. Matches how the Streamlivr app indexes audio for video, so agent results line up with in-app search. Priced per creator credited and attributed to each one when the payment settles. One cent in USDC per creator credited, with a one cent minimum per request. A page that credits 50 creators costs $0.50. The 402 invoice carries the exact amount before anything is signed. Paid route: USDC 0.01 per creator credited, one cent minimum and 2 maximum, settled over x402 on Celo. Without a payment the call returns the x402 payment requirements instead of data, and the requirements carry the exact amount for the call that was asked for.
```

### `public_posts`

- The name "public_posts" says "post": a word for a change.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.
- Tag outbound: The name "public_posts" says "post": it sends or publishes something to other people.
- Findings: warn base64-blob, warn annotation-conflict

Description, as the server wrote it:

```untrusted-server-text
Published public content from every public account: title, caption, hashtags, media type and length, engagement counts, and thumbnail. Each row labels the audio owner and attribution; borrowed sound credits its owner. Searchable by title, caption, tag or the public creator's country with ?q=. Combine with ?limit= and ?sort=newest|views, and follow nextCursor for more. Priced per creator credited. One cent in USDC per creator credited, with a one cent minimum per request. A page that credits 50 creators costs $0.50. The 402 invoice carries the exact amount before anything is signed. Paid route: USDC 0.01 per creator credited, one cent minimum and 2 maximum, settled over x402 on Celo. Without a payment the call returns the x402 payment requirements instead of data, and the requirements carry the exact amount for the call that was asked for.
```

## Only reads (1)

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

### `x402_ping`

- The name "x402_ping" says "ping": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Returns liveness and the settlement network the API is running on. Use it to confirm a buyer wallet, facilitator key, and x402 client all work before paying for data. Paid route: USDC 0.01 per request, settled over x402 on Celo. Without a payment the call returns the x402 payment requirements instead of data, and the requirements carry the exact amount for the call that was asked for.
```

## Claude Code permissions

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

```json
{
  "permissions": {
    "allow": [
      "mcp__streamlivr__x402_ping"
    ],
    "ask": [
      "mcp__streamlivr__creator_listings",
      "mcp__streamlivr__public_posts",
      "mcp__streamlivr__music_catalog",
      "mcp__streamlivr__creator_profile"
    ],
    "deny": []
  }
}
```

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

- `mcp__streamlivr__public_posts`: outbound

- **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 4 tools that change things (4 write). Whether a call also works without credentials was not tested: tools are never called.

https://api.streamlivr.com/mcp: tools/list returned 5 tools to an anonymous client, including creator_listings (write), public_posts (write), music_catalog (write), creator_profile (write)
