# ECZ-ID MCP Verifier — Proprietary Limited-Use License Copyright (c) 2026 EcoCitizenZ. All rights reserved. ECZ-ID, ECZ-ID MCP Verifier, the ECZ-ID Resolver, and the related names, marks, schemas, output formats, reason codes, result states, and workflows are proprietary to EcoCitizenZ. This is a proprietary license. It is **not** an open-source or "free software" license. No open-source rights are granted. Your rights are limited to exactly what Section 1 states. ## 1. Limited grant Subject to your full and continuing compliance with this license, EcoCitizenZ grants you a personal, non-exclusive, non-transferable, non-sublicensable, revocable license, at no charge, to: (a) install the official, unmodified ECZ-ID MCP Verifier as distributed by EcoCitizenZ; and (b) operate it — at no charge, for personal, organisational, development, CI/CD, and internal business purposes — to check the public posture of the ECZ-ID Resolver and to read public, machine-readable ECZ-ID Resolver output. "Installation" includes only the technical copying strictly required to download, cache, and run the official package on systems you control. ## 2. Prohibited uses Except for the limited grant in Section 1, you may **not**, in whole or in part, directly or indirectly: - copy the software beyond the technical copying required to install and run the official package; - modify, adapt, translate, or create derivative works of the software; - redistribute, publish, host, mirror, or otherwise make the software available to any third party; - sublicense, sell, rent, lease, lend, or otherwise commercialize the software or access to it; - wrap, embed, bundle, white-label, rebrand, or re-package the software, or offer it as part of another product or service; - create, or assist any party in creating, a product or service that competes with the software or with any EcoCitizenZ product; - clone, re-implement, or reproduce — whether or not using the software's source — the resolver, proof, trust, Know-Your-Agent (KYA), or MCP assurance functionality of the software or of any EcoCitizenZ system; - remove, obscure, alter, or replace any ECZ-ID branding, names, marks, notices, default routes, or endpoints; - use the ECZ-ID schemas, output formats, report structures, reason codes, result states, or workflows — in whole or in part — to design, train, build, or operate a same or similar product or service; or - reverse engineer, decompile, or disassemble the software, except to the limited extent this restriction is prohibited by applicable law. ## 3. No patent license No patent rights are granted under this license, whether expressly, by implication, by estoppel, or otherwise. All patent rights are expressly reserved by EcoCitizenZ. Nothing in this license grants you any right under any patent, patent application, or other intellectual-property right of EcoCitizenZ. ## 4. No trademark license No right to use any EcoCitizenZ name, logo, or mark is granted, except as strictly required to run the official, unmodified package without alteration of its branding or routes. ## 5. Reservation of rights All rights not expressly granted in Section 1 are reserved by EcoCitizenZ. The software is licensed, not sold. ## 6. No warranty THE SOFTWARE IS PROVIDED "AS IS", WITHOUT WARRANTY OF ANY KIND, EXPRESS OR IMPLIED, INCLUDING BUT NOT LIMITED TO THE WARRANTIES OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, AND NONINFRINGEMENT. The software performs local checks and reporting only. It does not certify safety, approve any target, or write truth. Local policy decides. Re-check before reliance. ## 7. Limitation of liability TO THE MAXIMUM EXTENT PERMITTED BY LAW, IN NO EVENT SHALL ECOCITIZENZ BE LIABLE FOR ANY CLAIM, DAMAGES, OR OTHER LIABILITY ARISING FROM OR IN CONNECTION WITH THE SOFTWARE OR ITS USE. ## 8. Termination This license terminates automatically if you breach any term. On termination you must stop using and remove all copies of the software, except cached copies deleted in the ordinary course of operation. ## 9. Free-forever distribution posture The official, unmodified ECZ-ID MCP Verifier and its bundled GitHub Action are offered free of charge — now and in the future ("free forever") — under this Proprietary Limited-Use License, for the purposes described in Section 1. "Free forever" refers to price only. It grants no open-source rights, no redistribution rights, and no right beyond Section 1. EcoCitizenZ may publish the official package and Action through public distribution channels, including the npm registry and the GitHub Action Marketplace. Public visibility of the source — for transparency or installation — does not place the software in the public domain, does not make it open source, and does not grant any right beyond Section 1. All prohibitions in Sections 2–5 continue to apply.
