## Exfil surface

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

| private-data | Reads files, mail, messages, databases, secrets, calendars or repositories. | `mcp__sapo__sapo_list_customers` `mcp__sapo__sapo_list_locations` |
| untrusted-input | Brings in text someone else can write: web pages, inbound email, messages, issues and comments. | `mcp__sapo__sapo_count_customers` `mcp__sapo__sapo_count_orders` `mcp__sapo__sapo_count_products` `mcp__sapo__sapo_get_customer` `mcp__sapo__sapo_get_order` `mcp__sapo__sapo_get_product` `mcp__sapo__sapo_get_product_variant` `mcp__sapo__sapo_get_store` `mcp__sapo__sapo_list_custom_collections` `mcp__sapo__sapo_list_customers` `mcp__sapo__sapo_list_inventory_items` `mcp__sapo__sapo_list_inventory_levels` `mcp__sapo__sapo_list_locations` `mcp__sapo__sapo_list_order_transactions` `mcp__sapo__sapo_list_orders` `mcp__sapo__sapo_list_price_rules` `mcp__sapo__sapo_list_product_variants` `mcp__sapo__sapo_list_products` `mcp__sapo__sapo_set_inventory_level` `mcp__sapo__sapo_update_order` |

## Findings

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

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

annotations: {"readOnlyHint":true,"destructiveHint":false,"openWorldHint":true}; The name "sapo_list_order_transactions" says "list": a word for reading.
```


## Deletes or cancels (2)

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

### `sapo_set_inventory_level`

- The name "sapo_set_inventory_level" says "set": a word for a change.
- 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: set the physical stock (on_hand) of one inventory item at one location to an exact quantity, with a reason. This OVERWRITES the current number and is recorded as a stock adjustment: read the level first (sapo_list_inventory_levels). PUT /admin/inventory_levels/set.json.
```

### `sapo_update_order`

- The name "sapo_update_order" says "update": a word for a change.
- 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: set the note and/or the tags of an order (Sapo only lets an order's items and quantities stay fixed after creation). The value REPLACES the existing note or tags: read the order first to keep what is there. PUT /admin/orders/{id}.json.
