## Exfil surface

36 private-data -> untrusted-input -> outbound paths in this server alone. Denying 2 outbound tools breaks every one: `mcp__agentlair__delegate_task`, `mcp__agentlair__send_email`.

| Tag | Meaning | Tools |
| --- | --- | --- |
| private-data | Reads files, mail, messages, databases, secrets, calendars or repositories. | `mcp__agentlair__calendar_get_feed` `mcp__agentlair__calendar_list_events` `mcp__agentlair__list_addresses` `mcp__agentlair__read_message` `mcp__agentlair__vault_get` `mcp__agentlair__vault_list` |
| untrusted-input | Brings in text someone else can write: web pages, inbound email, messages, issues and comments. | `mcp__agentlair__calendar_get_feed` `mcp__agentlair__list_addresses` `mcp__agentlair__read_message` |
| outbound | Can carry data to people or systems: it sends, posts or publishes, or takes a recipient, channel or URL. | `mcp__agentlair__delegate_task` `mcp__agentlair__send_email` |

- Tag outbound: The input takes a destination (input.to): what the tool writes goes there.

Description, as the server wrote it:

```untrusted-server-text
Delegate a task to another AgentLair agent. The task is delivered to the agent's inbox and picked up asynchronously. Use this when you need another agent to do something — send an email, run a deployment, do research, etc.
```

### `send_email`

- The name "send_email" says "send": a word for sending, and what is sent cannot be taken back.
- The input addresses people (input.to): what it sends cannot be taken back.

Description, as the server wrote it:

```untrusted-server-text
Send an email from your AgentLair address (@agentlair.dev) to any recipient. No SMTP or DNS setup needed.

```

### `check_inbox`

- Nothing in its name or description says what it does, so it is counted as a write.

Description, as the server wrote it:

```untrusted-server-text
Check the inbox for an @agentlair.dev email address. Returns recent messages with sender, subject, and received time.
```

### `claim_address`

- Nothing in its name or description says what it does, so it is counted as a write.

Description, as the server wrote it:

```untrusted-server-text
Check trust readiness before engaging with an agent. Returns a ReadinessCard: trust score, behavioral maturity level, whether it's safe to engage, and any caveats.

```

### `vault_put`

- The name "vault_put" says "put": a word for a change.

Description, as the server wrote it:

```untrusted-server-text

## Remote posture

What an anonymous client saw at the remote endpoint, last 2026-11-05T03:19:51.135Z, unchanged since 2026-11-05T03:19:51.135Z. No credentials were sent and no tool was called. Values are shown as the endpoint returned them. Method: https://anlyon.dev/methodology#remote-posture

| HTTP status of an anonymous initialize | `200` |
| tools/list served without credentials | `yes` |

- **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 9 tools that change things (2 destructive, 2 irreversible, 5 write). Whether a call also works without credentials was not tested: tools are never called.

https://agentlair-mcp-server.amdal-dev.workers.dev/mcp: tools/list returned 15 tools to an anonymous client, including vault_delete (destructive), calendar_delete_event (destructive), send_email (irreversible), delegate_task (irreversible), check_inbox (write) and 4 more
