Contract Information Extractor

App Name: Contract Information Extractor
App Slug: contract-information-extractor
Version: 1.0.0
Support Email: sidcraigau@gmail.com

Contract Information Extractor is a read-only, stateless Cloudflare Workers MCP server for organizing explicitly stated information from user-supplied contract text. It does not store contract text, does not use login, OAuth, a database, external APIs, model APIs, file upload, OCR, PDF parsing, or external write operations.

Tools

• extract_contract_metadata: extracts explicitly stated contract type, parties, effective date, expiration date, contract value, payment terms, and governing law.
• extract_contract_clauses: extracts explicitly present payment, termination, confidentiality, liability, intellectual property, and delivery clauses.
• extract_contract_obligations: organizes explicitly stated parties, obligations, deliverables, deadlines, and dependencies.

All tools share the same input shape:

{
  "contract_text": "The complete or partial contract text supplied by the user.",
  "request_intent": "Optional requested action description."
}

contract_text is required and must be a non-empty string at runtime. request_intent is optional and is used only to reject requests outside the extraction scope.

Each tool returns structuredContent matching its outputSchema. Successful partial extraction is still status: "success"; unavailable fields are empty strings or empty arrays and are listed in missing_fields.

Scope Boundaries

This app only extracts information directly supported by the supplied plain text. It does not provide legal advice and does not judge contract legality, validity, enforceability, breach, fairness, risk, or which party has greater responsibility. It does not recommend, modify, rewrite, draft, submit, send, save, or negotiate contract terms.

The current version accepts only plain text in contract_text.
