## Exfil surface

12 private-data -> untrusted-input -> outbound paths in this server alone. Denying 1 private-data tool breaks every one: `mcp__humanforai__check_message_thread`.

| Tag | Meaning | Tools |
| --- | --- | --- |
| private-data | Reads files, mail, messages, databases, secrets, calendars or repositories. | `mcp__humanforai__check_message_thread` |
| untrusted-input | Brings in text someone else can write: web pages, inbound email, messages, issues and comments. | `mcp__humanforai__check_message_thread` `mcp__humanforai__check_task_status` `mcp__humanforai__get_human_services` `mcp__humanforai__message_human_operator` `mcp__humanforai__reply_in_message_thread` `mcp__humanforai__submit_human_task` |

## Findings

No check matched anything in these tool definitions.


## Can't be undone (2)

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

### `message_human_operator`

- The description's first verb is "send": a word for sending, and what is sent cannot be taken back.
- Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data.
- Tag outbound: The description's first verb is "send": it sends or publishes something to other people.

Description, as the server wrote it:

```untrusted-server-text
Send a free-form message to the human operator — questions, scoping, custom or recurring projects, anything that is not yet a ready-made task. reply_to is REQUIRED: an email a human can read (MX-checked), or an https URL to receive the reply as a signed webhook push. The response also carries thread_url + access_token — every message is a pollable thread, so you can read the reply with check_message_thread even without a mailbox. Keep the token: it is shown only once.
```

### `reply_in_message_thread`

- The name "reply_in_message_thread" says "reply": a word for sending, and what is sent cannot be taken back.
- Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data.
- Tag outbound: The name "reply_in_message_thread" says "reply": it sends or publishes something to other people.

Description, as the server wrote it:

```untrusted-server-text
Add a follow-up to a thread you opened — answer a question the operator asked, add detail, correct yourself, or withdraw the request. Prefer this over sending a brand-new message about the same subject. Needs the message_id and access_token from the submission response.
```

## Changes things (1)

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

### `submit_human_task`

- The name "submit_human_task" says "submit": 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
Submit a task for the human operator to perform in the real world. Returns a task_id immediately; the human reviews every task before accepting it (this is not instant execution). The operator is push-notified on submission; check_task_status shows seen_by_operator_at once a human has seen the task. Free during the pilot. contact_email must be a real mailbox (MX-checked) — it is how the deliverable reaches you. No mailbox? Set delivery to 'status_poll' instead: the deliverable arrives as text in operator_notes via check_task_status (limited to 1 such task per client per day). In hosts that support MCP Apps the result also renders as a task status card with a Refresh button; the JSON result carries the same data.
```

## Only reads (3)

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

### `check_message_thread`

- The description's first verb is "read": a word for reading.
- Tag private-data: The name "check_message_thread" says "message": it reads messages. The description's first sentence says "read" and "thread": it reads messages.
- Tag untrusted-input: The name "check_message_thread" says "message": it reads messages, which other people can write. The description's first sentence says "read" and "thread": it reads messages, which other people can write.

Description, as the server wrote it:

```untrusted-server-text
Read the thread for a message you sent: the original text, every reply oldest-first, and whether the operator has answered. Needs the message_id and the access_token from the submission response. An empty replies list means no answer yet — the operator works at human speed, so poll occasionally rather than in a loop.
```

### `check_task_status`

- The name "check_task_status" says "status": a word for reading.
- 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
Look up a submitted task by its task_id. Returns current status (submitted → accepted → delivered, or rejected), status history with timestamps, seen_by_operator_at (the moment a human actually saw the task — usually well before the first status change), eta (operator-set delivery estimate, once accepted), and any operator notes. Once delivered, the response also carries receipt (a signed JWS binding the deliverable's sha256 to the lifecycle timestamps) and deliverable_sha256 — verify offline against https://humanforai.dev/.well-known/jwks.json. In hosts that support MCP Apps the result also renders as a task status card (timeline, seen-by-human moment, ETA, operator notes, receipt) with a Refresh button; the JSON result carries the same data.
```

### `get_human_services`

- The name "get_human_services" says "get": a word for reading.
- 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
Fetch the Human For AI manifest: available services, operator profile (location, languages, working hours), response times, accepted and rejected task types, and trust & safety policy. Call this first to decide whether and how to hire the human. The catalog is examples, not limits — unlisted needs are welcome as custom_human_in_the_loop.
```

## Claude Code permissions

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

```json
{
  "permissions": {
    "allow": [
      "mcp__humanforai__get_human_services",
      "mcp__humanforai__check_task_status",
      "mcp__humanforai__check_message_thread"
    ],
    "ask": [
      "mcp__humanforai__submit_human_task",
      "mcp__humanforai__message_human_operator",
      "mcp__humanforai__reply_in_message_thread"
    ],
    "deny": []
  }
}
```

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

- `mcp__humanforai__get_human_services`: untrusted-input
- `mcp__humanforai__submit_human_task`: untrusted-input
- `mcp__humanforai__check_task_status`: untrusted-input
- `mcp__humanforai__message_human_operator`: untrusted-input, outbound
- `mcp__humanforai__check_message_thread`: private-data, untrusted-input
- `mcp__humanforai__reply_in_message_thread`: untrusted-input, outbound

- **high** 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 3 tools that change things (2 irreversible, 1 write). Whether a call also works without credentials was not tested: tools are never called.

https://humanforai.dev/mcp: tools/list returned 6 tools to an anonymous client, including message_human_operator (irreversible), reply_in_message_thread (irreversible), submit_human_task (write)
