## Exfil surface

No private-data -> untrusted-input -> outbound path in this server alone: no tool is tagged untrusted-input.

| Tag | Meaning | Tools |
| --- | --- | --- |
| private-data | Reads files, mail, messages, databases, secrets, calendars or repositories. | `mcp__merchant-api__connect_status` `mcp__merchant-api__get_docs` |
| untrusted-input | Brings in text someone else can write: web pages, inbound email, messages, issues and comments. | none |
| outbound | Can carry data to people or systems: it sends, posts or publishes, or takes a recipient, channel or URL. | `mcp__merchant-api__updateApp` |

## Findings

- **high** References to secrets on disk in `connect_status` ([sensitive-path](https://anlyon.dev/methodology#sensitive-path))

```untrusted-server-text
The description refers to ".env".

description: "...exactly once: save it to the project's .env immediately, never print it in logs). T..."
```

- **warn** Annotations that disagree with the tool in `connect_status` ([annotation-conflict](https://anlyon.dev/methodology#annotation-conflict))

```untrusted-server-text
The server marks "connect_status" as not read-only (readOnlyHint: false), and its words say it reads.

annotations: {"readOnlyHint":false,"destructiveHint":false}; The name "connect_status" says "status": a word for reading.
```

- **warn** Annotations that disagree with the tool in `archiveSubscriptionPlan` ([annotation-conflict](https://anlyon.dev/methodology#annotation-conflict))

```untrusted-server-text
The server marks "archiveSubscriptionPlan" not destructive (destructiveHint: false), and its own name, description or input give the class "destructive".

annotations: {"readOnlyHint":false,"destructiveHint":false}; The name "archiveSubscriptionPlan" says "archive": a word for removing or ending something.
```


## Deletes or cancels (4)

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

### `archiveSubscriptionPlan`

- The name "archiveSubscriptionPlan" says "archive": a word for removing or ending something.
- The server marks it not destructive (destructiveHint: false), but an annotation never lowers a class.
- Findings: warn annotation-conflict

Description, as the server wrote it:

```untrusted-server-text
Stop new signups for a plan (live subscriptions keep renewing).
```

### `cancelSubscription`

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

Description, as the server wrote it:

```untrusted-server-text
Stop future charges for one subscription (paid time runs out).
```

### `deleteCheck`

- The name "deleteCheck" 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 an unclaimed check (refunds the hold).
```

### `deleteInvoice`

- The name "deleteInvoice" 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 an unpaid invoice.
```

## Changes things (5)

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

### `connect`

- The description's first verb is "start": a word for a change.

Description, as the server wrote it:

```untrusted-server-text
Start token issuance WITHOUT the Mini App UI: creates a merchant-app request and returns a t.me approve link plus a poll_secret. Show the link to the human — they approve with one button in the @tgpaycryptobot bot — then call connect_status with the poll_secret. Use only when no API token is configured yet.
```

### `connect_status`

- The name "connect_status" says "status": a word for reading.
- The server marks it as not read-only (readOnlyHint: false).
- Tag private-data: The input names a secret (input.poll_secret), and the tool reads: it reads secrets.
- Findings: high sensitive-path, warn annotation-conflict

Description, as the server wrote it:

```untrusted-server-text
Poll a connect request. Returns pending | denied | expired, or — once approved — the app id and the API TOKEN (returned exactly once: save it to the project's .env immediately, never print it in logs). The token is SCOPED (read, invoices, subscriptions, webhooks) — it cannot move money out of the app; transfers/refunds/checks need the primary token the human holds in the Mini App. Poll every 3-5 seconds while pending.
```

### `createInvoice`

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

Description, as the server wrote it:

```untrusted-server-text
Create a one-off payment invoice; the payer opens result.mini_app_invoice_url. See the invoices doc.
```

### `createSubscriptionPlan`

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

Description, as the server wrote it:

```untrusted-server-text
Create an IMMUTABLE recurring-billing plan; send payers to result.mini_app_subscribe_url. See the subscriptions doc.
```

### `updateApp`

- The name "updateApp" says "update": a word for a change.
- Tag outbound: The input takes a URL (input.webhook_url): a request to a URL can carry data to whoever runs it.

Description, as the server wrote it:

```untrusted-server-text
Update app name / webhook_url (https) / webhook_events opt-in list. Needs the 'webhooks' scope (the connect-issued token has it) or the primary token. See the webhooks doc for the event types and signature verification.
```

### `get_docs`

```untrusted-server-text
The endpoint served tools/list without credentials, and the list has 9 tools that change things (4 destructive, 5 write). Whether a call also works without credentials was not tested: tools are never called.

https://app.tgpaycrypto.com/mcp: tools/list returned 20 tools to an anonymous client, including deleteInvoice (destructive), deleteCheck (destructive), archiveSubscriptionPlan (destructive), cancelSubscription (destructive), connect (write) and 4 more
