## Exfil surface

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

| 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__instamojo__instamojo_create_payment_request` `mcp__instamojo__instamojo_create_refund` `mcp__instamojo__instamojo_disable_payment_request` `mcp__instamojo__instamojo_enable_payment_request` `mcp__instamojo__instamojo_get_payment` `mcp__instamojo__instamojo_get_payment_request` `mcp__instamojo__instamojo_get_refund` `mcp__instamojo__instamojo_list_payment_requests` `mcp__instamojo__instamojo_list_refunds` |

### `instamojo_create_refund`

- The name "instamojo_create_refund" says "create": a word for a change.
- The name "instamojo_create_refund" also says "refund": a word that usually means money moves, which cannot be taken back.
- The server marks it destructive (destructiveHint: true).
- 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
WRITE (moves money): refund a payment, in full or in part. Instamojo allows only ONE refund per payment, so a partial refund cannot be topped up later. Without confirm: true nothing is sent and the call returns a preview of the refund; ask the user to confirm, then call again with confirm: true. Reason types: RFD = duplicate/delayed payment, TNR = product/service no longer available, QFL = customer not satisfied, QNR = product lost/damaged, EWN = digital download issue, TAN = event was canceled/changed, PTH = problem not described above. POST /refunds/.
```

### `instamojo_disable_payment_request`

- The name "instamojo_disable_payment_request" says "disable": a word for a change.
- The name "instamojo_disable_payment_request" also says "payment": a word that usually means money moves, which cannot be taken back.
- The server marks it destructive (destructiveHint: true).
- 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
WRITE: disable a payment request so its link no longer accepts payments (instamojo_enable_payment_request undoes it). Existing payments are not touched. POST /payment-requests/{id}/disable/.
```

### `instamojo_create_payment_request`

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

```

### `instamojo_enable_payment_request`

- The name "instamojo_enable_payment_request" says "enable": a word for a change.
