## 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__research__get_product_terms` `mcp__research__get_sec_filing_bundle` |
| 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 `how_to_pay_x402` ([annotation-conflict](https://anlyon.dev/methodology#annotation-conflict))

```untrusted-server-text
The server marks "how_to_pay_x402" read-only (readOnlyHint: true), and its own name, description or input give the class "irreversible".

annotations: {"readOnlyHint":true}; The name "how_to_pay_x402" says "pay": 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.

### `how_to_pay_x402`

- The name "how_to_pay_x402" says "pay": 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
The x402 payment flow for these products, the client libraries that automate it, and where the authoritative terms live.
```

## Changes things (1)

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

### `check_10q_coverage`

- 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
Free coverage check against SEC EDGAR for any U.S. ticker: confirms whether 10-Q Highlights can serve it, lists available fiscal periods (newest first), and returns the payable URLs. No charge; the paid product is the extraction itself.
```

## Only reads (5)

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

### `get_line_item_trajectory`

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

Description, as the server wrote it:

```untrusted-server-text
Three fiscal years of income statement, balance sheet and cash flow lines for one company, in one standard layout, scaled to revenue, with per-year slopes where computed. Levels and slopes only. AMD and AVGO return the COMPLETE sheet free, in the exact schema every paid sheet uses. Any other covered ticker returns its payable URL and x402 terms ($0.05 per call). Tickers outside the covered list return not_covered.
```

### `get_product_terms`

- The name "get_product_terms" says "get": a word for reading.
- Tag untrusted-input: The description's first sentence says "url": it reads web pages, which anyone can write.

Description, as the server wrote it:

```untrusted-server-text
Exact x402 payment terms for one payable URL or product path (price, asset, network, payTo, scheme). The live 402 response's PAYMENT-REQUIRED header remains the authoritative terms document; this tool mirrors the same constants the gates are built from.
```

### `get_sample_card`

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

Description, as the server wrote it:

```untrusted-server-text
One COMPLETE quarterly card, free — the identical payload the paid route returns for that card, not a trimmed preview. Two company-quarters (AMD fy2026-q2, MRVL fy2027-q2) are published free in both the quantitative and qualitative families, in the exact schema and field names every paid card uses, so a parser written against a sample works unchanged against any card you buy. Use it as a zero-cost integration test before paying for coverage. Any other ticker returns not_a_sample.
```

### `get_sec_filing_bundle`

- The name "get_sec_filing_bundle" says "get": a word for reading.
- Tag untrusted-input: The description's first sentence says "html": it reads web pages, which anyone can write.

Description, as the server wrote it:

```untrusted-server-text
One company's SEC 10-K or 10-Q as a ZIP: the filing HTML as filed, the SEC-rendered consolidated statements in a workbook (IS, BS, CF where present; the manifest names the sheets, and a two-sheet workbook is disclosed on the bundle), a manifest naming the accession, and a pointer to the quarterly cards for the same filing. Source material only; nothing inferred. Lists every bundle held for the ticker with its free manifest URL; AMD, MRVL, AVGO and MRCY are free in full. Other bundles return their payable URL and x402 terms ($0.05 each). Tickers with no bundle return not_covered. The ZIP bytes themselves are only served over the HTTP routes.
```

### `list_research`

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

Description, as the server wrote it:

```untrusted-server-text
The full alpha402x catalog: every payable research product (empirical multibagger profiles, fiscal-year-end WACC builds, 10-Q highlight extractions, quarterly quantitative and qualitative cards) with prices, payable URLs, and free guide pages. All prices are USDC per call over x402.
```

## Claude Code permissions

For `.claude/settings.json`, assuming the server is installed as `research`:

```json
{
  "permissions": {
    "allow": [
      "mcp__research__list_research",
      "mcp__research__get_product_terms",
      "mcp__research__get_sample_card",
      "mcp__research__get_line_item_trajectory",
      "mcp__research__get_sec_filing_bundle"
    ],
    "ask": [
      "mcp__research__check_10q_coverage",
      "mcp__research__how_to_pay_x402"
    ],
    "deny": []
  }
}
```

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

- `mcp__research__get_product_terms`: untrusted-input
- `mcp__research__get_sec_filing_bundle`: untrusted-input

## Remote posture

What an anonymous client saw at the remote endpoint, last 2026-10-22T14:27:22.778Z, unchanged since 2026-10-22T14:27:22.778Z. 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 | `2` |

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

https://alpha402x.com/mcp: tools/list returned 7 tools to an anonymous client, including how_to_pay_x402 (irreversible), check_10q_coverage (write)
```
