## Findings

No check matched anything in these tool definitions.


## Changes things (2)

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

### `check_visa_free_eligibility`

- 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
Use when someone asks whether a passport holder can enter mainland China without a visa, and for how long. Inputs: "nationality" (English country name, e.g. "Germany"). Output: JSON with visa_free_for_ordinary_passports, max_days, and every applicable route (30-day unilateral exemption, mutual agreements, 240-hour transit, Hainan 30-day) with conditions, validity dates and official NIA/MFA/embassy source links; dataset last checked 2026-10-18. Not legal advice. Cost: 1 prepaid credit per call with "Authorization: Bearer <key>"; without credits it returns a 402 payment_required result with buy links (see get_pricing).
```

### `latest_regulation_changes`

- 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
Use to brief a foreign business on recent official Chinese regulations and policy releases (State Council English releases, MOFCOM). Inputs: optional "limit" (1-20, default 5), "topic" (tag/keyword, e.g. "trade", "export control"), "since" (YYYY-MM-DD). Output: JSON list of items with date, source, title, summary, tags and a link to the original. Cost: 1 prepaid credit per call with "Authorization: Bearer <key>"; without credits it returns a 402 payment_required result with buy links (see get_pricing).
```

## Only reads (3)

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

### `get_pricing`

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

Description, as the server wrote it:

```untrusted-server-text
Use when the user asks about cost, hits the free limit, or needs more calls. Inputs: none. Output: JSON with the free-tool limit, prepaid credit packs and their Stripe Payment Links, the USDC-on-Base endpoint and steps, and the cost of each tool. Cost: free, no key, 50 free-tool calls per IP per day in total.
```

### `list_capabilities`

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

Description, as the server wrote it:

```untrusted-server-text
Use first to see what this server covers and which tools are free. Inputs: none. Output: JSON with each tool, its cost, data coverage (visa-free routes for mainland China; official regulation releases), dataset dates and auth method. Cost: free, no key, 50 free-tool calls per IP per day in total.
```

### `sample_eligibility`

- The description's first verb is "preview": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Use to preview the shape and quality of eligibility data before paying. Inputs: optional "nationality" (English country name; default "Germany"). Output: a short sample: whether ordinary passports are visa-free, max days, route names and one source link. For full routes, conditions, dates and all sources use check_visa_free_eligibility. Cost: free, no key, 50 free-tool calls per IP per day in total.
```
