**5 tools: 1 can delete or cancel things, 2 change things and 2 only read.**

## 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__file-relay__get_file_info` `mcp__file-relay__read_file` |
| untrusted-input | Brings in text someone else can write: web pages, inbound email, messages, issues and comments. | `mcp__file-relay__create_upload_link` `mcp__file-relay__get_file_info` `mcp__file-relay__relay_attached_file` |
| outbound | Can carry data to people or systems: it sends, posts or publishes, or takes a recipient, channel or URL. | none |

## Findings

No check matched anything in these tool definitions.


## Deletes or cancels (1)

Removes, cancels or revokes something. Claude Code: deny.

### `delete_file`

- The name "delete_file" says "delete": a word for removing or ending something.
- The server marks it destructive (destructiveHint: true).

Description, as the server wrote it:

```untrusted-server-text
Delete a relayed file before it expires. Requires the delete_token returned at upload.
```

## Changes things (2)

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

### `create_upload_link`

- The name "create_upload_link" says "create": a word for a change.
- Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data.

Description, as the server wrote it:

```untrusted-server-text
Relay a file of any size up to 100 MB. Save the file to local disk first, call this with its path, then run the returned curl command in your shell to upload it. The download link works as soon as the upload finishes. Requires outbound network access to code.easyllms.com; if curl is blocked, ask the user to allow that domain in their sandbox network settings (on claude.ai: Settings > Capabilities > Code execution).
```

### `relay_attached_file`

- Nothing in its name or description says what it does, so it is counted as a write.
- Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data.

Description, as the server wrote it:

```untrusted-server-text
ChatGPT only: relay a file from the conversation (the host passes it as a file reference) and get a temporary download link.
```

## Only reads (2)

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

### `get_file_info`

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

Description, as the server wrote it:

```untrusted-server-text
Look up a relayed file by id or download URL: name, size, type, expiry and download link.
```

### `read_file`

- The name "read_file" says "read": a word for reading.
- Tag private-data: The name "read_file" says "read" and "file": it reads files. The description's first sentence says "read" and "file": it reads files.

Description, as the server wrote it:

```untrusted-server-text
Read a relayed file's content (up to 1 MB) so an agent can pick up a file someone else relayed. Text comes back as text, images as images, other files as base64.
```

## Claude Code permissions

For `.claude/settings.json`, assuming the server is installed as `file-relay`:

```json
{
  "permissions": {
    "allow": [
      "mcp__file-relay__get_file_info",
      "mcp__file-relay__read_file"
    ],
    "ask": [
      "mcp__file-relay__create_upload_link",
      "mcp__file-relay__relay_attached_file"
    ],
    "deny": [
      "mcp__file-relay__delete_file"
    ]
  }
}
```

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

- `mcp__file-relay__create_upload_link`: untrusted-input
- `mcp__file-relay__relay_attached_file`: untrusted-input
- `mcp__file-relay__get_file_info`: private-data, untrusted-input
- `mcp__file-relay__read_file`: private-data
