Document Integrity Validator MCP

![ToolRank](https://toolrank.dev/ranking)

Before your agent accepts, processes, or acts on any document received from an external party -- verify it is internally consistent and matches the known standard for its type. One call. Any document. Machine-readable verdict.

What it does

Checks any document for internal consistency, completeness, and anomalies against the known international standard for that document type. Accepts base64 image or extracted text. Returns a structured verdict with a machine-readable agent_action field.

Supported standards include: ICAO Document 9303 (passports), Hague-Visby Rules 1968 (bills of lading), UCP 600 (trade finance documents), ISPM 12/IPPC/FAO (phytosanitary certificates), Vienna Convention on Road Traffic 1968 (driving licences), and more.

Returns UNKNOWN_DOCUMENT_TYPE rather than guessing on unfamiliar documents -- refusal is correct behaviour, not a failure.

AI-powered reasoning -- NOT a database lookup.

Tools

check_document (Free tier: 10 calls/month)

Checks a single document against its international standard.

Input:

document_text (string, optional) -- extracted text from the document
document_image (string, optional) -- base64 encoded image (raw base64 or data URL)
document_type_hint (string, optional) -- agent belief about document type
issuing_jurisdiction (string, optional) -- country or issuing body

At least one of document_text or document_image is required.

Response: ``json { "agent_action": "PROCEED", "verdict": "PASS", "confidence": "HIGH", "document_type_identified": "Bill of Lading", "assessed_against": "Hague-Visby Rules 1968", "known_issuing_standard": "IMO", "flags": [], "reason": "Document is internally consistent and compliant with Hague-Visby Rules 1968.", "analysis_type": "AI-powered reasoning -- NOT a database lookup", "checked_at": "2026-05-06T10:00:00.000Z", "_disclaimer": "..." } ``

agent_action values:

PROCEED -- document passed
VERIFY_MANUALLY -- flags found, agent should flag for human review
HOLD -- document failed, do not proceed
REFER_TO_HUMAN -- document type unknown, refer for manual assessment

check_document_package (Paid tier only)

Checks 2-20 related documents individually then cross-checks all for consistency conflicts.

Input:

documents (array, min 2, max 20) -- each item has: label (required), document_text, document_image, document_type_hint, issuing_jurisdiction

Cross-checks performed: weights/quantities/amounts, party names, reference numbers, dates, commodity descriptions, port references.
