Leash Index

Terms of Use

The Leash Index is published by Media Yard LLC. By using it, or by submitting a server to it, you agree to these terms.

What the index is

The index classifies MCP servers by what their tools/list manifests declare, using the method published on the methodology page. Scores, bands and findings are the output of that method applied to a manifest on the date shown. They are opinions derived from disclosed rules and disclosed inputs.

They are not statements about how any product behaves, whether it is secure, or whether it provides controls outside MCP. A product can offer revocation, expiry, audit logs or spending limits that a manifest has no way to declare and the index cannot see. Nothing here is a certification, a security audit, a penetration test, or professional, legal or security advice.

No reliance, no warranty

The index is provided as is and as available, without warranties of any kind, express or implied, including accuracy, completeness, fitness for a particular purpose and non-infringement. Classifications are made by rules that are known to misread some tools, as the methodology discloses. Do not rely on the index as the sole basis for any decision.

Limitation of liability

To the fullest extent permitted by law, Media Yard LLC is not liable for any indirect, incidental, special, consequential or punitive damages, or any loss of profits, revenue, data or goodwill, arising from the index or from reliance on it. Where liability cannot be excluded, it is limited to the greater of the amount you paid Media Yard LLC for use of the index in the prior twelve months or one hundred US dollars. Some jurisdictions do not allow these limits, so they may not apply to you.

Names and marks

Product and company names identify the servers described and belong to their owners. Their use does not imply affiliation with, sponsorship by or endorsement of Media Yard LLC or the index. The index does not display third-party logos.

Corrections

A maintainer can correct a listing by submitting the current manifest and proving control of the origin the listing was verified from. Corrections are published alongside the record they correct, never over it. Anyone who believes a listing is inaccurate may also write to support@leashkit.com.

Submission Terms

These additional terms apply when you submit a server.

  1. Authority. You confirm that you maintain the server, that you are authorised by its owner to submit it, and that the manifest is the server's genuine tools/list response.
  2. Licence. You grant Media Yard LLC a worldwide, non-exclusive, royalty-free, perpetual licence to store, reproduce and publish the manifest, and to publish the scores, classifications and findings derived from it, including in the record history of the listing.
  3. Accuracy. You will not submit a manifest that is false, altered to mislead, or that belongs to a server you do not maintain. You are responsible for losses caused by a submission that breaches these terms.
  4. Discretion. Media Yard LLC may decline, delay or remove any submission or listing. Submitting does not guarantee a listing, a particular score, or any change to an existing one.
  5. Your contact details are handled as described in the Privacy Notice.

Changes

These terms may change. The version in force is the one published here, with the date below.

Governing law

These terms are governed by the laws of the State of New Jersey, without regard to conflict-of-laws rules.
