## 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__ai__list-webhook-events` |
| untrusted-input | Brings in text someone else can write: web pages, inbound email, messages, issues and comments. | `mcp__ai__list-endpoints` `mcp__ai__search` |
| 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 `list-webhook-events` ([annotation-conflict](https://anlyon.dev/methodology#annotation-conflict))

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

annotations: {"readOnlyHint":true,"destructiveHint":false,"openWorldHint":false}; The name "list-webhook-events" says "list": a word for reading.
```

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

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

annotations: {"readOnlyHint":true,"destructiveHint":false,"openWorldHint":false}; The description's first verb is "call": a word for a change.
```


## Changes things (2)

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

### `branch-overview`

- The description's first verb is "call": a word for a change.
- 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
Call this when the user is new to Branch or is asking what Branch is, what it does, how its core objects relate (organizations, workers, wallets, payment profiles, disbursements), or where to begin an integration. Returns a one-page orientation: the object model, the worker lifecycle from onboarding through payment, the two integration approaches, and the sandbox and production environments. For specific procedures or API details, use search, fetch, and get-endpoint instead — this tool is orientation only.
```

### `list-webhook-events`

- The name "list-webhook-events" says "list": a word for reading.
- The description's first verb is "call": a word for a change.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.
- Tag private-data: The description's first sentence says "branch": it reads repositories.
- Findings: warn annotation-conflict

Description, as the server wrote it:

```untrusted-server-text
Call this when the user asks about Branch webhooks, events, notifications, or callbacks — including which events exist, what data an event contains, or which event fires at a given point in worker onboarding or payment. Returns the complete catalog of all 22 Branch webhook events with their payload fields. Use the fetch tool with a listed doc id to get full details and a JSON example for a specific event.
```

## Only reads (6)

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

### `fetch`

- The name "fetch" says "fetch": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Gets detailed content for documentation by ID returned from the `search` tool.
```

### `get-endpoint`

- The name "get-endpoint" says "get": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Gets detailed information about a specific API endpoint, including security schemes and servers
```

### `get-server-variables`

- The name "get-server-variables" says "get": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Gets the server variables for each server within a specific OpenAPI spec.
```

### `list-endpoints`

- The name "list-endpoints" says "list": a word for reading.
- Tag untrusted-input: The description's first sentence says "list" and "http": it reads web pages, which anyone can write.

Description, as the server wrote it:

```untrusted-server-text
Lists all API paths and their HTTP methods with summaries, organized by path. Results can be passed directly into 'get-endpoint'.
```

### `search`

- The name "search" says "search": a word for reading.
- Tag untrusted-input: The description's first sentence says "search" and "url": it reads web pages, which anyone can write.

Description, as the server wrote it:

```untrusted-server-text
Searches through documentation with the given search query, returning a list of results with ID, title, and URL.
```

### `search-endpoints`

- The name "search-endpoints" says "search": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Performs a deep search through paths, operations, and parameters to discover relevant API endpoints. Use this tool to find specific API capabilities, required parameters, or data models based on search keywords. Results can be passed directly into 'get-endpoint'.
```

## Claude Code permissions

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

```json
{
  "permissions": {
    "allow": [
      "mcp__ai__list-endpoints",
      "mcp__ai__get-endpoint",
      "mcp__ai__search-endpoints",
      "mcp__ai__get-server-variables",
      "mcp__ai__search",
      "mcp__ai__fetch"
    ],
    "ask": [
      "mcp__ai__list-webhook-events",
      "mcp__ai__branch-overview"
    ],
    "deny": []
  }
}
```

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

- `mcp__ai__list-endpoints`: untrusted-input
- `mcp__ai__search`: untrusted-input
- `mcp__ai__list-webhook-events`: private-data
