## 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__chinaapi__chinaapi_get_model` |
| 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.


## Changes things (1)

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

### `chinaapi_estimate_cost`

- 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
Estimate the USD cost of a workload on one model from its published per-meter prices: Standard, and Paid where it is lower. Pass quantities in the model's own units — tokens for text models, characters for speech synthesis, audio seconds for transcription, requests, images or video seconds for per-call and per-second models; a quantity the model does not price is refused. Tiered models are estimated tier by tier. The result is an estimate, not a quote.
```

## Only reads (3)

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

### `chinaapi_get_model`

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

Description, as the server wrote it:

```untrusted-server-text
Get one model by its exact ID: base URL and endpoints, the Standard and Paid price snapshot per meter with the time it was read and the price-book versions, context window and modalities, capability contract, limits, and ChinaAPI links (model page, a start link to try it, the agents guide). The live price on the model page is authoritative.
```

### `chinaapi_get_recipe`

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

Description, as the server wrote it:

```untrusted-server-text
Get a runnable request for one model — endpoint, headers, JSON body or multipart form, a curl command, and for video the polling step — exactly as ChinaAPI's /agents page shows it. Optionally include the configuration that points a coding agent (Claude Code, Codex, Cursor, …) at ChinaAPI. The request uses $CHINAAPI_KEY; never put a real key into it.
```

### `chinaapi_list_models`

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

Description, as the server wrote it:

```untrusted-server-text
List the models ChinaAPI serves, optionally filtered by capability, task, maker or a model-ID substring. Each entry has the exact model ID, maker, capabilities and tasks, context window, headline Standard prices (and Paid prices where they are lower) and the model's ChinaAPI page. Sorted by maker, then model ID; page with cursor. Use chinaapi_get_model for one model's endpoints, full prices and limits.
```

## Claude Code permissions

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

```json
{
  "permissions": {
    "allow": [
      "mcp__chinaapi__chinaapi_get_model",
      "mcp__chinaapi__chinaapi_get_recipe",
      "mcp__chinaapi__chinaapi_list_models"
    ],
    "ask": [
      "mcp__chinaapi__chinaapi_estimate_cost"
    ],
    "deny": []
  }
}
```

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

- `mcp__chinaapi__chinaapi_get_model`: untrusted-input

## Remote posture

What an anonymous client saw at the remote endpoint, last 2026-10-22T14:19:24.519Z, unchanged since 2026-10-22T14:19:24.519Z. 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 | `1` |
| 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` |

- **warn** 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 1 tool that changes things (1 write). Whether a call also works without credentials was not tested: tools are never called.

https://api.chinaapi.ai/mcp: tools/list returned 4 tools to an anonymous client, including chinaapi_estimate_cost (write)
