Overview

AI-generated overview

Remote MCP server with 15 deterministic business-validation tools for tax IDs, VAT, IBAN, LEI, bank accounts, phone, FX rates, holidays and customs codes.

What you can do
  • Validate company and tax identifiers: tax IDs for 15 countries, EU VAT via VIES, IBANs, LEIs and bank accounts (CLABE, ABA, SWIFT/BIC)
  • Look up reference data: postal codes, industry codes (NAICS, NACE, CPV, SCIAN), HS/HTS tariff codes and VAT/GST rates
  • Check contact details: normalize phone numbers to E.164 and test whether an e-mail domain receives mail
  • Get official figures: exchange rates for a date, business-day arithmetic and public holidays
  • Compute Mexican payroll: ISR withholding, IMSS, Infonavit and net pay, plus SAT CFDI 4.0 catalog values
When to use it
Useful when an assistant must verify supplier, customer or payment details instead of guessing, for example before paying an invoice or onboarding a company. Also fits finance, tax and trade workflows needing official rates, holidays, tariff codes or Mexican payroll figures.
Requirements
Remote Streamable HTTP endpoint hosted on Apify; no local install. Requires an Apify API token sent as a Bearer token in the Authorization header, or an x402 prepaid token. Network access to the endpoint.
Before you install
Paid per call: $0.005 per single call and $0.002 per item in batches, so usage spends money on the Apify account or prepaid balance. The Authorization header carries a secret API token. Validation inputs (tax IDs, IBANs, e-mails, phone numbers) are sent to a third-party hosted service.

Installation

In SourceWeft

  1. Open Hexadata Tools in the dashboard and add it to a workspace.
  2. Connect Authorization token credentials. They are stored privately and never shown on public pages.
  3. Enable the server for the chats that should use its tools.

Web executable via Streamable HTTP. Remote servers run from the web runtime once configured in a workspace.

Use with an agent

Paste this prompt into Claude Code, Codex, Cursor or another agent — or into SourceWeft chat. The agent reads this server's install guide, shows you its publisher, endpoint and sign-in, and adds it to your client once you agree. Keys never go into a command.

Read https://sourceweft.com/mcp/io.github.4robot%2Fhexadata-tools/install.md and connect the MCP server it describes to my client. Before changing any config, show me its publisher, endpoint and sign-in method and wait for my OK. Never put an API key in a command or in a file I would commit; ask me where it should come from.

Read the install guide the agent follows

README

Hexadata Tools — business validation MCP server for AI agents

Hexadata Tools is a remote MCP server (Streamable HTTP, hosted on Apify) with 15 deterministic tools that an AI agent should call instead of guessing: check digits, official tables and official calculations. No LLM inside: the same input always gives the same answer, nothing is stored, and you pay per call ($0.005 per single call, $0.002 per item in batches; invalid input is free).
