Security Report
This is a well-designed finance MCP server for e-invoice validation with appropriate security controls. The codebase properly handles authentication via environment variables, validates inputs, and avoids sensitive data leakage. The server correctly requires an API key for the main validation tool while keeping offline reference features available. A minor code quality improvement regarding error message truncation is noted but does not impact security. Supply chain analysis found 3 known vulnerabilities in dependencies (0 critical, 3 high severity). Package verification found 1 issue.

eleata e-invoice MCP server
Validate EU electronic invoices and explain validation error codes directly from your AI coding agent (Claude, Cursor, Copilot, …). It wraps the hosted eleata validation API plus a bundled offline error-code reference.
Never ship a broken invoice. When you ask your agent "is this FatturaPA / XRechnung / Peppol file valid?", it runs the official Schematron rules and gets back the rule id and the fix — before a rejection (an SdI scarto, a Chorus Pro refusal, a KSeF error) ever happens.
Tools
| Tool | What it does | API key |
|---|---|---|
validate_einvoice | Validate one invoice (Peppol BIS 3.0, EN 16931 UBL/CII, XRechnung 3.0.x, Factur-X/ZUGFeRD, UBL, CII). Returns valid/invalid + each rule id, explanation and fix. | required |
list_formats | List the formats eleata validates today + roadmap. | none |
explain_error_code | Explain one error code (e.g. 00400, BR-DE-21) in plain English, with the fix. Works offline. | none |
Setup
- Get a free API key (200 validations/month, no card) at https://eleata.io/signup/.
