**4 tools: 1 do something that can't be undone and 3 only read.**

| Group | Class | Tools | Claude Code |
| --- | --- | --- | --- |
| Deletes or cancels | destructive | 0 | deny |
| Can't be undone | irreversible | 1 | ask |
| Changes things | write | 0 | ask |
| Only reads | read | 3 | allow |

## 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__radar__get_server_capabilities` |
| untrusted-input | Brings in text someone else can write: web pages, inbound email, messages, issues and comments. | `mcp__radar__get_server_capabilities` |
| 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 `get_server_capabilities` ([annotation-conflict](https://anlyon.dev/methodology#annotation-conflict))

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

annotations: {"readOnlyHint":true,"destructiveHint":false,"idempotentHint":true,"openWorldHint":false}; The name "get_server_capabilities" says "get": a word for reading.
```


## Can't be undone (1)

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

### `get_server_capabilities`

- The name "get_server_capabilities" says "get": a word for reading.
- The description says "cannot be undone".
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.
- Tag private-data: The description's first sentence says "message": it reads messages.
- Tag untrusted-input: The description's first sentence says "message": it reads messages, which other people can write.
- Findings: warn annotation-conflict

Description, as the server wrote it:

```untrusted-server-text
Gives the tool names on one tracked vendor MCP server, grouped by the most serious thing each tool is counted as able to do: money (move or spend money), destructive (changes that cannot be undone, such as deleting), send (send messages or publish to other people), write (create or change things), unclear, or read (labelled as only reading). Labels come from Stackduke's open-source scanner: the server's own annotations where it sends them, otherwise a guess from the tool's name that leans to the more serious kind. They are not verified by calling the tools, and they do not mean a server is safe. Tool descriptions are never included. A server the tracker does not follow gets a 'not covered' answer.
```

## Only reads (3)

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

### `find_tool`

- The name "find_tool" says "find": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Finds which tracked vendor MCP servers list a tool with a given name, and the kind each is counted as. By default it matches the whole name, ignoring case; with match set to 'contains' it finds names containing the text (at least 3 characters). Searches only the servers the tracker follows, at their latest listing.
```

### `get_recent_changes`

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

Description, as the server wrote it:

```untrusted-server-text
Gives the changes seen to one tracked vendor MCP server's tool list in the last 1 to 30 days (default 7): tools added and removed, tools changed with the fields that changed (title, description, input or output schema, annotations), and tools now counted as able to do more than before. Each change is dated as seen between two checks, because the tracker compares one listing with the next. The answer also says how many checks were made in the period, which ones failed, and any stretch that was not watched. A change made and undone between two checks is not seen. Changed text is never quoted. A server the tracker does not follow gets a 'not covered' answer.
```

### `list_tracked_servers`

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

Description, as the server wrote it:

```untrusted-server-text
Lists the official vendor MCP servers that Stackduke's public tracker follows. For each: its tool count, its tools counted by kind (money, destructive, send, write, unclear, read), when it was last checked and when its tools were last listed. Only these servers are covered. The tracker data is published about once a day. Read-only: answers come from Stackduke's published tracker data, and no vendor's server is contacted.
```

## Claude Code permissions

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

```json
{
  "permissions": {
    "allow": [
      "mcp__radar__list_tracked_servers",
      "mcp__radar__get_recent_changes",
      "mcp__radar__find_tool"
    ],
    "ask": [
      "mcp__radar__get_server_capabilities"
    ],
    "deny": []
  }
}
```

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

- `mcp__radar__get_server_capabilities`: private-data, untrusted-input
