## MCP tools (4)

### `customs_check` (~312 tokens)

Check a declaration ledger for internal inconsistency

Run the customs declaration rule pack over a declaration ledger and return the findings as a Markdown report. The input is a JSON or YAML table: one row per document line, with columns such as 品名 (description), 商品编号 (HS code), 币制 (currency), 毛重/净重 (gross/net weight), 申报日期 (declaration date) and 总价 (total value). Call customs_schema for the exact field names and their aliases. The report lists only literal differences from the declared checks — an HS code that is not ten digits, a currency that is not a 3-letter code, gross weight below net weight, a duplicated document number, a date that does not parse or is in the future, an unfilled placeholder. Each finding carries the clause it rests on, or states that the clause text was not obtained. It does NOT decide whether a declaration is correct, whether goods are misclassified, or whether duty is owed. It performs no writes and needs no credentials. Read the "未执行的检查" (checks not executed) section at the end: it names every rule that did not run and why, and a report is only as complete as that list allows.

Input parameters:

- `material` (string, required): The ledger as JSON or YAML text. Either an object with a `rows` array, or a bare array of row objects.
- `onlyRules` (array): Run only these rule ids, e.g. ["CD-002"]. Omit to run the whole pack.

### `customs_read_docx` (~220 tokens)

Extract readable text from a .docx

Extract text from a .docx file so it can be turned into a ledger for customs_check. Paragraphs come out one per line; table rows come out as "| a | b | c |" lines. Merged cells are marked "↔", meaning "this cell is merged with the one to its left and holds no value of its own" — do not read it as a missing value. A vertically merged cell repeats the value above it, which is what a reader of the document sees. Reads exactly the one path given, opens it read-only, and refuses anything larger than 20 MB. No other file is touched, no network is used, nothing is written. Only a path ending in .docx is accepted: legacy .doc/.wps are a different binary format and PDF is not parsed on purpose — a PDF table loses its cell structure, and guessing it produces a ledger that is wrong in ways the check cannot detect.

Input parameters:

- `path` (string, required): Absolute or working-directory-relative path to the .docx file.

### `customs_schema` (~88 tokens)

Show the ledger column contract

Return the column contract for customs_check: the accepted field names, every alias each field answers to (for example 品名 / goodsName, 币制 / currency), and the header-level fields. Call this first when assembling a ledger, because a column name the reader does not recognise is silently dropped and the corresponding rule then reports nothing. Read-only, no parameters, no network, no writes.

### `customs_rulebook` (~134 tokens)

List the rules and how many can quote their source

Return every rule in the pack: id, title, severity, the basis kind (direct clause / derived from principle / local configuration), the document and clause it cites, and whether the pack actually holds the verbatim clause text. The `coverage` object states how many rules carry a verbatim clause and how many record that the clause was not obtained, so a reader can weigh the report instead of trusting it. This is the answer to "how much of this is actually backed by a quoted regulation" — the number is computed from the pack, not asserted. Read-only, no parameters, no network, no writes.

## Common questions

### What is the Customs Declaration Consistency MCP server?

Customs Declaration Consistency is an MCP server listed in the public MCP registry as io.github.PerryLink/dsh-customs. Read-only MCP server that checks a Chinese customs declaration ledger for internal inconsistency. This page covers its npm package (dsh-customs-mcp).

### Is the Customs Declaration Consistency MCP server safe to use?

Customs Declaration Consistency scores 69 out of 100 on VerifyMCP. We found no known CVEs affecting it as of 5 November 2026. It declares no install or post-install scripts. That is a record of what we were able to check automatically, not an endorsement. The category breakdown on this page shows every signal behind the number, including the ones we could not confirm.

### What tools does the Customs Declaration Consistency MCP server expose?

Customs Declaration Consistency exposes 4 tools: customs_check, customs_read_docx, customs_schema, customs_rulebook. Their descriptions and schemas cost roughly 754 tokens of context every time the server is loaded.

### Is the Customs Declaration Consistency MCP server still maintained?

Customs Declaration Consistency is still listed as active in the MCP registry. We last reached this channel on 5 November 2026. Those dates come from our own scans of the registry and the channel itself, not from anything the publisher announced.

### What licence is the Customs Declaration Consistency MCP server under?

Customs Declaration Consistency declares the Apache-2.0 licence, which is OSI-approved. That covers the source only, and says nothing about the cost of any service it calls.

### What did VerifyMCP test on the Customs Declaration Consistency MCP server?

VerifyMCP ran 16 checks on Customs Declaration Consistency, covering Malware scan, Known CVEs, Install scripts, Dependency health and 12 more. Endpoint Security and Transport & Reachability do not apply to an npm package, so they were not tested. The score does not measure everything, and the scoring documentation lists what it leaves out.
