## Exfil surface

No private-data -> untrusted-input -> outbound path in this server alone: no tool is tagged private-data 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. | `mcp__zensched__account_recover_start` `mcp__zensched__account_signin_start` `mcp__zensched__account_signup_start` `mcp__zensched__feedback_submit` |
| 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 `zensched_guide` ([annotation-conflict](https://anlyon.dev/methodology#annotation-conflict))

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

annotations: {"readOnlyHint":true,"destructiveHint":false,"openWorldHint":false}; The description's first verb is "start": a word for a change.
```


## Deletes or cancels (1)

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

### `account_recover_verify`

- The input takes a statement or command to run (input.code), which can change anything it can reach.
- The server marks it destructive (destructiveHint: true).

Description, as the server wrote it:

```untrusted-server-text
Lost API key (step 2 of 2): verify the code. Issues a fresh key and revokes ALL previous keys.
```

## Changes things (9)

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

### `account_create`

- The name "account_create" says "create": a word for a change.

Description, as the server wrote it:

```untrusted-server-text
Create a ZenSched org without email (MCP-only agents). No OTP — returns org_id + zsc_ key immediately. Store the key securely. To attach a contact email later for human recovery, call account_set_contact. Rate-limited aggressively.
```

### `account_recover_start`

- The name "account_recover_start" says "start": 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
Lost API key (step 1 of 2): sends a verification code to the org owner email. Then call account_recover_verify. Prefer account_signin_start if you only need to reconnect — Recover revokes ALL keys.
```

### `account_signin_start`

- The name "account_signin_start" says "start": 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
Reconnect an existing org without rotating keys (step 1 of 2): emails a 6-digit code to the owner. Then account_signin_verify. Prefer this over Recover.
```

### `account_signin_verify`

- The input takes a statement or command to run (input.code), which can change anything it can reach.

Description, as the server wrote it:

```untrusted-server-text
Reconnect an existing org without rotating keys (step 2 of 2): verify the emailed code. Call this after account_signin_start. If later org tools fail, call account_signin_verify again or account_use_key.
```

### `account_signup_start`

- The name "account_signup_start" says "start": 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
Create a ZenSched org (step 1 of 2): sends a 6-digit verification code to the email. Unauthenticated; rate-limited. Then call account_signup_verify.
```

### `account_signup_verify`

- The description's first verb is "create": a word for a change.
- The input takes a statement or command to run (input.code), which can change anything it can reach.

Description, as the server wrote it:

```untrusted-server-text
Create a ZenSched org (step 2 of 2): verify the emailed code. Returns org_id and your zsc_ API key (shown once). Claude.ai must then Connect → Sign in with the same email — do not keep calling org tools until Connect succeeds.
```

### `account_use_key`

- 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
Authenticate this connector with an existing zsc_ API key. Prefer this when the key is already in the conversation. If the connector shows Connected but org tools fail, call this or account_signin_start — do not look for a Connect button.
```

### `feedback_submit`

- The name "feedback_submit" 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
File a grievance or product recommendation. Free. Works even before you have an account. Categories: bug, friction, missing_capability, docs, billing, feature, other. Severity: low, medium, high, blocker. Include related_tool and paste error text in context when reporting a bug. A human reads every submission.
```

### `zensched_guide`

- The description's first verb is "start": a word for a change.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.
- Findings: warn annotation-conflict

Description, as the server wrote it:

```untrusted-server-text
START HERE. The ZenSched agent guide: how to Connect (Claude.ai) or use a zsc_ key, then fund → locations → workers → shifts → timesheets. Also covers the suggestion box (feedback_submit).
```

## Only reads (1)

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

### `account_auth_status`

- The name "account_auth_status" says "status": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Check whether this connector is signed in as a ZenSched org. Call this before account_get in a new session. Unauthenticated; never errors.
```

## Claude Code permissions

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

```json
{
  "permissions": {
    "allow": [
      "mcp__zensched__account_auth_status"
    ],
    "ask": [
      "mcp__zensched__zensched_guide",
      "mcp__zensched__feedback_submit",
      "mcp__zensched__account_create",
      "mcp__zensched__account_signup_start",
      "mcp__zensched__account_signup_verify",
      "mcp__zensched__account_recover_start",
      "mcp__zensched__account_signin_start",
      "mcp__zensched__account_signin_verify",
      "mcp__zensched__account_use_key"
    ],
    "deny": [
      "mcp__zensched__account_recover_verify"
    ]
  }
}
```

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

- `mcp__zensched__feedback_submit`: untrusted-input
- `mcp__zensched__account_signup_start`: untrusted-input
- `mcp__zensched__account_recover_start`: untrusted-input
- `mcp__zensched__account_signin_start`: untrusted-input

## Remote posture

What an anonymous client saw at the remote endpoint, last 2026-10-22T14:44:46.568Z, unchanged since 2026-10-22T14:44:46.568Z. No credentials were sent and no tool was called. Values are shown as the endpoint returned them. Method: https://anlyon.dev/methodology#remote-posture

| Fact | Observed |

| HTTP status of an anonymous initialize | `200` |

| Tools that change things, listed without credentials | `10` |
| Protocol version | `2025-06-18` |

- **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 10 tools that change things (1 destructive, 9 write). Whether a call also works without credentials was not tested: tools are never called.

https://mcp.zensched.com/mcp: tools/list returned 11 tools to an anonymous client, including account_recover_verify (destructive), zensched_guide (write), feedback_submit (write), account_create (write), account_signup_start (write) and 5 more
