**7 tools: 1 do something that can't be undone, 2 change things and 4 only read.**

## 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__agent-commerce__get_discovery_urls` |
| 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 `build_purchase_request` ([annotation-conflict](https://anlyon.dev/methodology#annotation-conflict))

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

annotations: {"readOnlyHint":true,"destructiveHint":false,"idempotentHint":true,"openWorldHint":false}; The name "build_purchase_request" says "purchase": a word that usually means money moves, which cannot be taken back.
```


## Can't be undone (1)

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

### `build_purchase_request`

- The name "build_purchase_request" says "purchase": a word that usually means money moves, which cannot be taken back.
- 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
Build a ready-to-send InstaVeil x402 POST request for one paid product so an autonomous agent can purchase with minimal integration work.
```

## Changes things (2)

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

### `execute_paid_product`

- The name "execute_paid_product" says "execute": a word for a change.

Description, as the server wrote it:

```untrusted-server-text
Execute a real x402-protected InstaVeil Instagram data API via MCP. First call without payment returns a free x402 V2 PaymentRequired structuredContent quote (isError=true). After a buyer wallet authorizes the exact Solana USDC payment, retry tools/call with the same arguments and params._meta['x402/payment'] containing its signed PaymentPayload (or payment_signature for clients without x402-over-MCP support). Verified data and payment settlement receipt follow as structuredContent and _meta['x402/payment-response']. No keys, automatic charges or simulated sales.
```

### `recommend_paid_product`

- Nothing in its name or description says what it does, so it is counted as a write.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.

Description, as the server wrote it:

```untrusted-server-text
Recommend the lowest-friction InstaVeil paid x402 product for an agent task, with exact price and resource URL.
```

## Only reads (4)

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

### `get_discovery_urls`

- The name "get_discovery_urls" says "get": a word for reading.
- Tag untrusted-input: The name "get_discovery_urls" says "get" and "url": it reads web pages, which anyone can write.

Description, as the server wrote it:

```untrusted-server-text
Return canonical machine-readable URLs for InstaVeil x402, OpenAPI, llms.txt and human fallback.
```

### `get_product`

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

Description, as the server wrote it:

```untrusted-server-text
Get one InstaVeil x402 product in decision-ready form before an agent spends USDC.
```

### `get_purchase_instructions`

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

Description, as the server wrote it:

```untrusted-server-text
Return exact machine purchase steps for one InstaVeil product using x402 V2 and Solana USDC.
```

### `list_paid_products`

- The name "list_paid_products" says "list": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
List all InstaVeil x402 products with current prices, resource URLs, input schemas and examples.
```

## Claude Code permissions

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

```json
{
  "permissions": {
    "allow": [
      "mcp__agent-commerce__list_paid_products",
      "mcp__agent-commerce__get_product",
      "mcp__agent-commerce__get_purchase_instructions",
      "mcp__agent-commerce__get_discovery_urls"
    ],
    "ask": [
      "mcp__agent-commerce__recommend_paid_product",
      "mcp__agent-commerce__build_purchase_request",
      "mcp__agent-commerce__execute_paid_product"
    ],
    "deny": []
  }
}
```

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

- `mcp__agent-commerce__get_discovery_urls`: untrusted-input

## Remote posture

What an anonymous client saw at the remote endpoint, last 2026-10-22T14:34:17.307Z, unchanged since 2026-10-22T14:34:17.307Z. 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://instaveil.com/mcp: tools/list returned 7 tools to an anonymous client, including build_purchase_request (irreversible), recommend_paid_product (write), execute_paid_product (write)
