ECZ-ID MCP Verifier
Terms
These terms apply to the ECZ-ID MCP Verifier agent plugin — the package eczid-mcp-verifier, version 0.1.1.
They are product-specific terms. They sit under the EcoCitizenz Terms of Service, which is the agreement between you and EcoCitizenz Ltd and which governs everything not addressed here.
- Applies to:
eczid-mcp-verifier0.1.1- Effective date:
- 3 September 2026
In short
- The plugin is free to install and use. There is no fee, no subscription and no account.
- The package is open source under the MITlicence. You may read, copy, modify and redistribute it on that licence's terms.
- It reads a public record. A result is evidence about public proof, never a verdict about safety, and no public proof found is neutral.
- It writes no truth. Running a check creates no ECZ-ID, no credential, no binding and no public proof, and changes nothing in the Resolver.
- The ECZ-ID name, branding and the wider service remain ours; the MIT licence covers the plugin code, not the trade marks.
- Governing law and the limits on our liability come from the EcoCitizenz Terms of Service. This page does not restate them differently.
How these terms fit together
The EcoCitizenz Terms of Service (last updated 31 August 2026) govern access to and use of EcoCitizenz websites, ECZ-ID products, TrustOps, the Resolver, developer tools, software, APIs and machine-facing interfaces. They expressly contemplate product-specific terms, and provide that where there is a conflict, the more specific agreed terms govern that particular service to the extent of the conflict.
This page is that more specific layer for this plugin. Read the two together. Where this page is silent — governing law, acceptable use in full, warranties, limitation of liability, changes, termination, contact — the EcoCitizenz Terms of Service applies unchanged, and nothing here is intended to broaden or narrow it.
Separately, the MIT licence granted with the source code governs your rights to copy, modify and distribute that code. Where the licence grants you a right, that right is not restricted by this page.
What the plugin is
ECZ-ID MCP Verifier is a free, read-only Agent Plugins 1.0.0 package. It contains a manifest, one skill document named ecz-id-verify, one MCP server declaration and its icons. It ships no review script and no server of its own.
Where your agent host runs local stdio MCP servers, the declaration launches the separately published ECZ-ID Verifier, @ecocitizenz/ecz-id-mcp-verifier@0.9.0, which offers three read-only tools: classify and check a target against the public ECZ-ID Resolver, explain a result, and re-read the Resolver before reliance.
Where your host does not run local MCP servers — including where only the skill directory is distributed — no server runs and no check is possible. In that case the plugin explains the vocabulary and routes you to the public record, and it is instructed never to simulate a result it did not obtain. Its behaviour on both routes is described on the Privacy page, and the source is public.
What you may do with it
You may install and run the plugin on your own machine and in your own agent host, for personal or business purposes, at no cost. You may check any target you are entitled to check, and you may share, publish or submit a result as you see fit — the result is yours.
Because the package is licensed under MIT, you may also read, copy, modify, merge, publish, distribute, sublicense and sell copies of it, subject to the licence conditions — principally that the copyright notice and permission notice are retained. The full text is in the repository licence file.
The ECZ-ID Verifier package the declaration launches is published separately, in its own repository, under the licence stated there. This page does not license that package, and does not restate its terms.
No account, registration, activation key or entitlement is needed, and none is created by using the plugin.
Your responsibility
You choose what to check, and you are responsible for the decision you take on the strength of a result. A check is an input to your judgement, not a substitute for it. In particular:
- a ResultState reports what the public record held at the moment it was read. It is not a statement that a target is safe, competent, solvent or fit for your purpose;
- no public proof found is neutral. It means nothing was found in the public record. It does not mean the target is unsafe, and your local policy decides what to do about it;
- public state changes. Re-check before reliance — that is what
ecz_recheck_resolverexists for — and do not present a historical result as current; - the policy mode you choose (OPEN, PREFER or REQUIRE) is your decision, not ours. ECZ-ID imposes no universal allow-or-block outcome;
- where your host offers no Verifier tools, the plugin cannot check anything. Treat any confident-sounding verification claim in that setting as a defect and report it.
No certification, approval or advice
This is the most important clause on the page, and it is not boilerplate. Consistent with the EcoCitizenz Terms of Service, the plugin and its results do not:
- certify that any MCP server, agent, API, package, domain or business is safe or secure;
- certify compliance with any law, regulation, standard or scheme, or constitute regulatory approval or approval by any authority, marketplace or platform;
- constitute an audit, an audit opinion, or an assurance engagement;
- constitute legal, regulatory, financial, insurance or other professional advice;
- establish the identity, authority, ownership or good standing of anyone beyond what the public record it read actually says;
- guarantee that a counterparty, platform or regulator will accept a result;
- replace your own due diligence.
A check produces evidence and reason codes, never a numeric safety, security or trust score, and never a grade or a pass mark. It also writes nothing: it cannot activate proof, mark anything bound, grant an entitlement or change any state in the Resolver, and no amount of checking creates a credential. The Resolver is read-only, and ECZ-ID Core remains the final authority on canonical state.
Acceptable use
The acceptable-use terms in the EcoCitizenz Terms of Service apply. In the specific context of this plugin, you must not:
- check targets you have no right to check, or make automated bulk requests against the Resolver or a third party's public surfaces beyond ordinary use;
- alter its output and present the altered version as the result of an ECZ-ID review;
- present a review as a certification, an audit, an approval or a statement of compliance, or otherwise misrepresent what it establishes;
- represent an expired, superseded or historical result as a current one;
- use the ECZ-ID name, logo or branding in a way that suggests endorsement, certification or a relationship that does not exist;
- imply that EcoCitizenz has verified, approved or is otherwise responsible for your product because you ran this plugin against it.
Intellectual property and licensing
The plugin package — its manifest, skill document, MCP server declaration and documentation — is released under the MIT licence, copyright EcoCitizenz Ltd. That licence, and not this page, is what grants you rights in the code.
The MIT licence covers the code. It does not transfer or license the ECZ-ID and EcoCitizenz names, logos, branding or product marks, which remain the property of EcoCitizenz Ltd, nor the wider ECZ-ID services, schemas, verification formats and infrastructure, which are governed by the EcoCitizenz Terms of Service. You may say truthfully that your project uses this plugin. You may not use our marks to suggest endorsement or certification.
The result of a check that you run is yours. We assert no ownership over it and receive no copy of it.
Availability, changes and updates
The plugin is provided as it is, when it is available. We may change, update, re-version, rename, deprecate or withdraw it, and we may change the skill, the version of the Verifier server it declares, or the routing guidance in a future version. We do not guarantee uninterrupted availability of any distribution channel, and no service level applies to it.
The plugin runs on your machine, so a version you have already installed keeps working whether or not it is still distributed. Because it is MIT-licensed, a copy you hold remains yours to use under that licence.
Distribution through a marketplace or agent-plugin directory does not guarantee continued listing, ranking, visibility or recommendation, and does not imply that the operator of that marketplace has endorsed, certified or reviewed the product.
Agent hosts, marketplaces and other third parties
You run this plugin inside an agent host operated by a third party, and you may have obtained it through a third-party marketplace or directory. Those platforms are not operated by EcoCitizenz. Your use of them is governed by their own terms and privacy policies, and they may impose requirements of their own; where a marketplace's mandatory terms govern a transaction on that marketplace, those terms apply to it.
EcoCitizenz is not responsible for the availability, behaviour, security or data handling of any agent host or marketplace, and nothing on these pages is a commitment made on their behalf. Naming a platform here identifies the software involved; it does not indicate affiliation, sponsorship or endorsement in either direction.
Links from a result to EcoCitizenz pages, or to public documentation elsewhere, are routing only. Setup, subscriptions and payment for paid ECZ-ID credentials happen in TrustOps under the EcoCitizenz Terms of Service. This plugin takes no payment and creates no entitlement.
Security research
EcoCitizenz supports good-faith security reporting. If you believe you have identified a vulnerability, report it through the route on the Support page rather than disclosing it publicly first.
When testing, you must not access customer data unnecessarily, destroy or alter data, disrupt production systems, perform denial-of-service testing, exploit a vulnerability beyond what is reasonably required to demonstrate it, or publicly disclose a vulnerability before reasonable coordinated disclosure where doing so would create material risk. These conditions are those set out in the EcoCitizenz Terms of Service.
Warranties and liability
The plugin package is distributed under the MIT licence, which provides the software as is and without warranty of any kind. That disclaimer applies to the code.
Beyond that, the warranty and liability terms in the EcoCitizenz Terms of Service apply, including the limits on liability and the exceptions to them. This page does not create a different liability position, and does not state a figure or a cap of its own — the Terms of Service is the place those are set.
Nothing on this page excludes or limits liability where it would be unlawful to do so, and nothing here affects rights you have under mandatory law, including consumer rights where they apply to you.
Governing law
The EcoCitizenz Terms of Service are governed by the laws of England and Wales, and set out the position on jurisdiction, including the protections that apply if you are a consumer. That governing-law position applies to these product terms as well. This page states no separate choice of law and no separate jurisdiction clause.

Plainly, so there is no doubt
- Running a check does not verify anyone. It reads a public record about a target you named, and reports what that record held.
- EcoCitizenz has not certified, approved or audited any target you check, and a result must not be presented as though we had.
- In a host with no Verifier tools configured, this plugin executes nothing. It must never appear to have checked something it could not check.
- No ECZ-ID product on this page is endorsed by, affiliated with or approved by any regulator, standards body, marketplace operator or AI platform.
