**5 tools: 1 do something that can't be undone, 2 change things and 2 only read.**

| --- | --- | --- | --- |

## Exfil surface

No private-data -> untrusted-input -> outbound path in this server alone: no tool is tagged private-data or untrusted-input 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. | none |
| outbound | Can carry data to people or systems: it sends, posts or publishes, or takes a recipient, channel or URL. | none |

## Findings

No check matched anything in these tool definitions.


## Can't be undone (1)

Sends, pays, publishes or merges: once done, it cannot be taken back. Claude Code: ask.

### `confirm_payment`

- The name "confirm_payment" says "payment": a word that usually means money moves, which cannot be taken back.

Description, as the server wrote it:

```untrusted-server-text
Confirm payment using a payment_token from checkout and a cc_token (credit card token).
Completes the TitanStore purchase and returns an order confirmation.
```

## Changes things (2)

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

### `add_to_cart`

- The name "add_to_cart" says "add": a word for a change.

Description, as the server wrote it:

```untrusted-server-text
Add a TitanStore product to your cart and receive a cart token.
Requires a valid SKU. Returns cart_token needed for checkout.
```

### `checkout`

- The name "checkout" says "checkout": a word for a change.

Description, as the server wrote it:

```untrusted-server-text
Initiate checkout for a cart. Provide cart_token from add_to_cart and a billing email.
Returns a payment_token required to complete the purchase.
```

## Only reads (2)

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

### `get_product`

- The name "get_product" says "get": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Retrieve full details for a TitanStore product by SKU.
Example SKUs: TS-001, TS-002, TS-003, TS-004, TS-005.
```

### `search_products`

- The name "search_products" says "search": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Search TitanStore product catalog.
Returns matching compute credits, API keys, storage, GPU instances, and support plans.
Filter by category: compute, api_access, storage, gpu, support.
```

## Claude Code permissions

For `.claude/settings.json`, assuming the server is installed as `titan-store`:

```json
{
  "permissions": {
    "allow": [
      "mcp__titan-store__search_products",
      "mcp__titan-store__get_product"
    ],
    "ask": [
      "mcp__titan-store__add_to_cart",
      "mcp__titan-store__checkout",
      "mcp__titan-store__confirm_payment"
    ],
    "deny": []
  }
}
```

## Remote posture

What an anonymous client saw at the remote endpoint, last 2026-10-22T14:51:59.694Z, unchanged since 2026-10-22T14:51:59.694Z. 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 |
| --- | --- |
| Reachable | `yes` |
| HTTP status of an anonymous initialize | `200` |
| tools/list served without credentials | `yes` |
| Tools that change things, listed without credentials | `3` |
| Protocol version | `2025-06-18` |
| WWW-Authenticate on 401 | `not observed` |
| resource_metadata in WWW-Authenticate | `none` |
| RFC 9728 protected resource metadata | `none` |
| Authorization servers | `none` |
| Legacy HTTP+SSE transport | `no` |
| Dynamic client registration | `not observed` |
| Client ID metadata documents | `not observed` |

- **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 3 tools that change things (1 irreversible, 2 write). Whether a call also works without credentials was not tested: tools are never called.

https://sati-search.fly.dev/mcp: tools/list returned 5 tools to an anonymous client, including confirm_payment (irreversible), add_to_cart (write), checkout (write)
```
