The tools this component advertises to a client, with an estimated token cost for each. Expand a tool to see its parameters and schema. The per-tool counts are indicative and are not scored directly; the schema's total context footprint is one signal in Schema Quality & AI Usability. A tool's description is untrusted text the model reads on every call, which is what makes this list a security surface and not just an inventory: how tool poisoning works →
check_balance Check remaining credits ~175
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.
Input schema present but exposes no named parameters.
| Name | Type | Req | Description |
|---|---|---|---|
| balance_credits | – | yes | 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 | yes | Credits charged within the period. |
| credits_spent_by_kind | object | yes | Credits charged within the period, by the kind that paid. |
| free_allowance | – | yes | 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credits; null when the account may not draw free credits (its email address is not confirmed, or its free credits were withdrawn) and for a key with no ac… |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 | – | yes | 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 | yes | Bounds of the current usage period (UTC calendar month). |
| scans | object | yes | – |
No examples provided.
scan_document Recognise a passport or ID document ~576
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.
| Name | Type | Req | Description |
|---|---|---|---|
| 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). |
| Name | Type | Req | Description |
|---|---|---|---|
| authenticity | – | yes | – |
| document | – | yes | – |
| fields | array | yes | 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 | – | yes | – |
| images | – | yes | – |
| meta | – | yes | – |
| mrz | – | yes | – |
| quality | – | yes | – |
No examples provided.
search_docs Search the doc.cheap API documentation ~164
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.
| Name | Type | Req | Description |
|---|---|---|---|
| limit | integer | – | Maximum number of results (default 5). |
| query | string | yes | What to search the documentation for. |
| Name | Type | Req | Description |
|---|---|---|---|
| results | array | yes | Matching sections, best first; empty when nothing matched. |
No examples provided.

Is the cheap.doc/mcp server safe to use?
cheap.doc/mcp scores 87 out of 100 on VerifyMCP. We found no known CVEs affecting it as of 28 September 2026. It declares no install or post-install scripts. Its build provenance is signed and verified. 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.
Is the cheap.doc/mcp server still maintained?
cheap.doc/mcp is still listed as active in the MCP registry. We last reached this channel on 28 September 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 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.
