## 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

- **high** References to secrets on disk in `check_stack_drift` ([sensitive-path](https://anlyon.dev/methodology#sensitive-path))

```untrusted-server-text
The description refers to ".mcp.json".

```

- **high** References to secrets on disk in `check_stack_drift` ([sensitive-path](https://anlyon.dev/methodology#sensitive-path))

```untrusted-server-text

```


## Changes things (1)

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

### `check_stack_drift`

- Nothing in its name or description says what it does, so it is counted as a write.
- Findings: high sensitive-path, high sensitive-path

Description, as the server wrote it:

```untrusted-server-text
Audit a package.json, requirements.txt, or .mcp.json configuration string against 256 live AI Agent SDKs and MCP servers. Flags breaking major version deltas, unpinned @latest MCP servers, and outdated dependencies with exact pin commands.
```

## Only reads (3)

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

### `get_archived_mcp_replacements`

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

Description, as the server wrote it:

```untrusted-server-text
Get the migration matrix for archived or frozen @modelcontextprotocol/server-* reference packages and their official 2026 vendor-maintained replacements.
```

### `get_package_stability`

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

Description, as the server wrote it:

```untrusted-server-text
Look up live npm or PyPI version, publish timestamp, 90-day release velocity, stability score (0-100), MCP tools/list schema drift risk, and before/after migration code for a specific AI Agent SDK or MCP server.
```

### `list_volatile_packages`

- The name "list_volatile_packages" says "list": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
List the fastest-changing or highest schema-drift-risk AI Agent SDKs and MCP servers from the live AgentBreakWatch telemetry index.
```

## Claude Code permissions

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

```json
{
  "permissions": {
    "allow": [
      "mcp__agentbreakwatch__get_package_stability",
      "mcp__agentbreakwatch__list_volatile_packages",
      "mcp__agentbreakwatch__get_archived_mcp_replacements"
    ],
    "ask": [
      "mcp__agentbreakwatch__check_stack_drift"
    ],
    "deny": []
  }
