Available components
How this component scores in each security and reliability category. Every signal is checked automatically against the live server, and we only credit what we can confirm. How we score → Why this is hard to score →
Endpoint Security83
- The endpoint's TLS certificate is valid, in date, and uses a strong key. View diagnostics → Pass
- No authorisation is required to call this server. Every tool declares its destructiveHint and none is destructive, so open access doesn't expose one. See how to fix → View diagnostics → Partial
- HTTPS is enforced; there's no plaintext access path. View diagnostics → Pass
- The HSTS (Strict-Transport-Security) header is present. View diagnostics → Pass
- DNSSEC is configured correctly; the domain's records validate against the full chain to the root. View diagnostics → Pass
Transport & Reachability100
- Verified streamable-http transport via a live MCP handshake. View diagnostics → Pass
Schema Quality & AI Usability90
- 100% of prompts and resources have a non-trivial description (not blank, and not just the item's name).Pass
- AI-judged instruction clarity (excellent).Pass
- Tool/resource definitions use about 3162 tokens (~46/item across 68 items; 3 tools + 65 resources), lean.Pass
- Usage-examples check failed: none of the tools include examples. See how to fix → Fail
Stability & Change Management17
- Stability observed for 5 of 30 days with no destabilising changes; credit accrues until the full window elapses.Partial
Tool Coverage100
- 100% of tools have a non-trivial description (not blank, and not just the tool's name).Pass
- 100% of tool parameters carry a description.Pass
- Structured output schemas are declared (100% of tools); any adoption earns full credit.Pass
Tool Safety100
- No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.Pass
- We read all 3 captured tool definition(s), and no name or description among them implies an irreversible operation.Pass
- An AI judge read all 5 captured unit(s) of tool text and found none that tries to manipulate the model reading it.Pass
Capabilities100
- Implements a supported MCP spec version (2025-11-25); the latest is 2026-07-28.Pass
How do I install the cheap.doc/mcp server?
cheap.doc/mcp is a hosted endpoint at https://mcp.doc.cheap/mcp, so there is nothing to install locally. Ready-made configuration for Claude, Cursor, VS Code, Codex and 5 more is on this page, copied from each client's own documentation.

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 ~513
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 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_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… |

| 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.
