Validates documents against international standards before agent action.

Captured live from the server via tools/list.

check_document

Validates a document against international standards for authenticity and internal consistency. Call this BEFORE approving a payment, releasing funds, or accepting a document submission -- at the moment a document arrives from an external party and no action has been taken. Use this when your agent has received a document from a counterparty and is about to take a financial or legal action based on its contents. Returns PASS / FLAG / FAIL / UNKNOWN_DOCUMENT_TYPE verdict assessed against ICAO 9303 (passports), Hague-Visby Rules 1968 (bills of lading), ICC UCP 600 (letters of credit and certificates of origin), and ISPM 12 (phytosanitary certificates). A FAIL verdict means the document is internally inconsistent indicating tampering -- acting on it creates unrecoverable compliance and financial exposure. Returns machine-readable verdict with named standard and specific flags, no further analysis needed.

Parameters (4)

document_textstring
Extracted text content from the document. Provide this or document_image or both.
document_imagestring
Base64 encoded document image. Accepts raw base64 or a data URL (data:image/jpeg;base64,...). Supported types: JPEG, PNG, GIF, WEBP.
document_type_hintstring
What the calling agent believes the document type is, e.g. "bill_of_lading", "passport", "certificate_of_origin". Optional -- the validator identifies the type independently.
issuing_jurisdictionstring
Country or issuing body, e.g. "Singapore", "ICAO", "United Kingdom". Narrows jurisdiction-specific standard selection.

check_document_package

Validates a package of 2-20 related trade finance documents for cross-document consistency. Call this BEFORE approving any multi-document trade finance transaction or cross-border shipment -- at the moment a set of 2-20 related documents arrives from an external party and funds have not been released. Use this when your agent has received a full trade finance package — such as invoice, bill of lading, and certificate of origin together — and must verify all documents are consistent with each other before releasing funds. Returns PASS/FLAG/FAIL verdict per document with mismatch details. Cross-checks all documents for consistency across numeric values, party names, reference numbers, dates, and commodity descriptions. A single inconsistency in a trade finance document package is a fraud signal -- funds released on a mismatched package have no recovery path. Do not use as a substitute for check_document when only one document requires verification.

Parameters (1)

documentsarrayrequired
Array of 2 to 20 related documents to assess individually and cross-check against each other. Each document must have a unique label.

Document Integrity Validator MCP

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.

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.
