## Trust breakdown

How this component scores in each security and reliability category. Every signal is checked automatically from public evidence about the published package, including repeated runs of it in an isolated sandbox, and we only credit what we can confirm. Scores are 0–100 per category. Scoring method: https://verifymcp.io/docs/scoring (what has changed: https://verifymcp.io/docs/scoring/changelog)

Scored 2026-09-28.

- **Supply Chain Security**: 23/100
  - No malware scan is available for this kind of package: the supply-chain vendors we use do not cover it. This is a permanent gap in our coverage, not a finding about the package.
  - Known CVEs were checked across the 111 of 111 dependencies we could resolve, so this covers what we could see, not the whole tree.
  - No install/post-install scripts declared.
  - 31 of 111 dependencies flagged as unhealthy.
- **Provenance & Transparency**: 39/100
  - Source repository is publicly reachable at the declared URL.
  - Provenance check failed: no build-provenance attestation is published.
  - Clear OSI-approved license (MIT).
  - Maintenance history not yet determined.
  - Security-disclosure policy not yet verified: we couldn't inspect the source repository.
- **Schema Quality & AI Usability**: 90/100
  - 100% of prompts and resources have a non-trivial description (not blank, and not just the item's name).
  - AI-judged instruction clarity (excellent).
  - Tool/resource definitions use about 3225 tokens (~47/item across 68 items; 3 tools + 65 resources), lean.
  - Usage-examples check failed: none of the tools include examples.
- **Stability & Change Management**: 0/100
  - Stability not yet verified: not enough scan history yet (needs a 30-day window).
- **Tool Coverage**: 100/100
  - 100% of tools have a non-trivial description (not blank, and not just the tool's name).
  - 100% of tool parameters carry a description.
  - Structured output schemas are declared (100% of tools); any adoption earns full credit.
- **Tool Safety**: 100/100
  - No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.
  - We read all 3 captured tool definition(s), and no name or description among them implies an irreversible operation.
  - An AI judge read all 5 captured unit(s) of tool text and found none that tries to manipulate the model reading it.
- **Capabilities**: 100/100
  - Implements a supported MCP spec version (2025-11-25); the latest is 2026-07-28.

**Unverified: 1 category.** A category scored 0 because we could not verify it: a data source with nothing on this package, evidence we could not reach, or a check we could not run. We only credit what we can confirm.

## Install

### How do I install the cheap.doc/mcp server?

cheap.doc/mcp ships as an MCPB bundle, a single file you download and open in an MCP host that supports MCPB bundles, such as Claude Desktop. The host reads the launch command from the bundle's own manifest, so there is no command to copy. The MCP registry declares no SHA-256 for this bundle, so there is no published digest to check the download against.

### `scan_document` (~576 tokens)

Recognise a passport or ID document

Recognise a passport, national ID card or driver's licence from a photo or scan and return what is printed on it as structured JSON. Inputs: the image as image_base64 (always available), image_path (a local file, and only inside the directory DOC_CHEAP_IMAGE_ROOT names) or image_url (https, on a public address); plus the optional expect_country, return_portrait, retain_hours, reference and idempotency_key. Output: a Scan object – meta (id, status, billed, confidence, timing), document (kind, issuing country, number, series, date of issue, date of expiry, whether it has expired and how many days are left), holder (given names, surname, date of birth, sex, nationality), fields (every field read off the printed page, each with its own confidence), mrz (whether the machine-readable zone checks out, why not when it does not, and its lines exactly as read), images, quality and authenticity – plus a one-line summary of the same result. Calls POST /v1/scans. Cost: it bills one credit ($0.01) only when a document is recognised; an unreadable image, an empty frame or an unsupported type costs nothing, and meta.billed says which happened. Without a key, the public sandbox key is used. It gives 10 free recognised documents per address in all, and at most 10 requests per address an hour, whatever their answer. Registering gives 100 free documents every month. Use it whenever someone hands over an identity document and wants it read, transcribed, or checked against what they claim – a name, a document number, a date of birth or an expiry date.

Input parameters:

- `expect_country` (string): ISO 3166-1 alpha-3 country you expect, or omit for any.
- `idempotency_key` (string): Makes a retried scan return the first result instead of charging again.
- `image_base64` (string): The document image as base64 (a data: URL is also accepted).
- `image_path` (string): Path to a local image file, inside the directory named by DOC_CHEAP_IMAGE_ROOT. Disabled unless that variable is set; send image_base64 instead.
- `image_url` (string): https: URL of an image on a public internet address, which the server fetches (25 MB maximum).
- `reference` (string): Your own correlation string, echoed back in the result.
- `retain_hours` (integer): Hours the result stays readable via GET /v1/scans/{id} (0 = store nothing). Omit it to use the account's own history-retention setting.
- `return_portrait` (boolean): Whether to include the holder photograph crop, images.main_photo (default true).

Output parameters:

- `authenticity`
- `document`
- `fields` (array): Every field the engine extracted off the printed document, re-keyed to our vocabulary – the open set. Always present; empty when nothing was extracted. A field read in more than one language appears…
- `holder`
- `images`
- `meta`
- `mrz`
- `quality`

### `check_balance` (~175 tokens)

Check remaining credits

Return how many credits are left on the account and what the current period has used: the balance, split into this month's free credits (100 every month, drawn first) and the paid credits, the credits spent, and the scan counters broken down by status (recognized, unreadable, no document found, unsupported document, rejected). Takes no arguments and calls GET /v1/usage; under the public sandbox key it answers without calling anything. One recognised document draws one credit, at $0.01; scans that recognised nothing are counted and never charged. Needs a real API key – under the public sandbox key there is no account behind the call, and the answer says so instead of reporting zeros that read like a balance. Use it before working through a batch of documents, or when a scan is refused for lack of credit.

Output parameters:

- `balance_credits`: Credits currently available to the account: this month's free credits plus the paid credits; null for a key with no account (the public sandbox key).
- `credits_spent` (integer): Credits charged within the period.
- `credits_spent_by_kind` (object): Credits charged within the period, by the kind that paid.
- `free_allowance`: This month's free credits, drawn before paid credits; null when the account may not draw free credits (its email address is not confirmed, or its free credits were withdrawn) and for a key with no ac…
- `paid_balance_credits`: Paid credits: bought or granted to the account, drawn once this month's free credits are used up, and never reset; null only for a key with no account (the public sandbox key).
- `period` (object): Bounds of the current usage period (UTC calendar month).
- `scans` (object)

### `search_docs` (~164 tokens)

Search the doc.cheap API documentation

Full-text search over the doc.cheap API documentation – endpoints, request options, every response field, the error codes and what to do about each, MRZ rules, retention and pricing. Takes a query and an optional limit (1 to 20, default 5), and answers with the matching sections: title, a snippet, and a link to the page. It reads a copy of the documentation shipped beside this server, so it makes no network call and works offline. Use it before guessing at a field name, an error code or a scan option – what it returns is the published contract rather than a recollection of it.

Input parameters:

- `limit` (integer): Maximum number of results (default 5).
- `query` (string, required): What to search the documentation for.

Output parameters:

- `results` (array): Matching sections, best first; empty when nothing matched.

### Is the cheap.doc/mcp server safe to use?

cheap.doc/mcp scores 49 out of 100 on VerifyMCP. 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 cheap.doc/mcp server expose?

cheap.doc/mcp exposes 3 tools: scan_document, check_balance, search_docs. Their descriptions and schemas cost roughly 915 tokens of context every time the server is loaded.

### What licence is the cheap.doc/mcp server under?

cheap.doc/mcp declares the MIT licence, which is OSI-approved. That covers the source only, and says nothing about the cost of any service it calls.
