Terms of Service

Last updated: 21 June 2026

These Terms of Service (the “Terms”) are a binding agreement between Comis d.o.o. (“Comis”, “we”, “us”, “our”) and you (“you”, “your”), and govern your download, installation and use of the MCP Peek desktop application (the “Software”) and the mcppeek.com website (together, the “Services”). By downloading, installing, activating or using the Software, you agree to these Terms. If you do not agree, do not download or use the Software.

1. The Software

MCP Peek is a local-first desktop application for developers that connects to Model Context Protocol (“MCP”) servers to inspect their catalog, run their tools, and act as a local proxy that captures requests and responses for debugging. It runs on macOS, Windows and Linux. A free tier is available; additional features are unlocked with a one-time paid “Pro” licence.

2. Licence grant

Subject to these Terms, Comis grants you a limited, non-exclusive, non-transferable, non-sublicensable and revocable licence to install and use the Software for your own personal or internal business purposes.

3. Licence keys & activation

After purchase, your licence key is delivered by email through Lemon Squeezy. The key is activated and validated through our own licensing service using a cryptographically signed grant that the app verifies offline, and a licence may be activated on one device at a time (you can deactivate a device to move it). Keep your key confidential; you are responsible for activity under it. Do not publish, share, resell or distribute licence keys. We may deactivate keys that are shared in breach of these Terms or obtained fraudulently.

4. Restrictions

You agree not to, and not to permit anyone else to:

5. Acceptable & lawful use of inspection and proxy features

MCP Peek connects to servers you configure and can act as a local proxy that captures requests and responses. You are solely responsible for ensuring you are authorised to connect to, inspect, intercept and capture traffic for the servers, endpoints and systems you use it with. Use these features only on systems you own or are explicitly authorised to test. You must comply with all applicable laws, including computer-misuse, interception, confidentiality and data-protection laws, and with any third-party terms. You are responsible for the MCP servers, endpoints and credentials you configure and for any data you process through them.

6. Third-party services & non-affiliation

The Software connects to third-party MCP servers and services that you choose. We do not control and are not responsible for those servers or services, their availability, or their content. MCP Peek is an independent product. “Model Context Protocol” and “MCP” are used descriptively to describe compatibility; MCP Peek is not affiliated with, sponsored by, or endorsed by Anthropic or any MCP server provider. All other trademarks are the property of their respective owners.

7. Purchases, pricing & taxes

MCP Peek Pro is sold through Lemon Squeezy, which acts as our Merchant of Record and is the seller of record for your purchase. Your purchase is therefore also subject to Lemon Squeezy’s buyer terms. Lemon Squeezy collects payment and calculates and remits any applicable VAT or sales tax. Prices may be shown excluding tax. Refunds are governed by our Refund Policy.

8. Intellectual property & feedback

The Software and all intellectual-property rights in it remain the exclusive property of Comis and its licensors. Except for the licence expressly granted in these Terms, no rights are transferred to you.

If you send us feedback, suggestions, feature requests, bug reports or other ideas — for example through our feedback board or by email — you grant Comis a perpetual, irrevocable, worldwide, royalty-free and transferable licence to use, modify and incorporate that feedback into the Software and our business for any purpose, without any obligation, attribution, confidentiality or compensation to you.

9. Privacy

Your use of the Services is also governed by our Privacy Policy, which explains the limited data we process. The Software is local-first: your server configurations and the traffic you inspect stay on your machine, and the app’s UI makes no network calls of its own.

10. Warranty & disclaimers

We warrant that, at the time of your download, the Software is free of malware and will perform substantially as described in its documentation. Please report any defect to support@mcppeek.com without undue delay after you discover it. No warranty applies where the Software has been modified, mishandled, or combined with unsuitable hardware or software, or where a fault is outside our control.

Except for the limited warranty above and to the maximum extent permitted by applicable law, the Software is provided “as is” and “as available” without further warranties of any kind, whether express or implied, including implied warranties of merchantability, fitness for a particular purpose and non-infringement, and we do not warrant that the Software will be uninterrupted or error-free. If you are a consumer, this section does not affect your mandatory statutory rights and guarantees (including conformity rights for digital content under applicable EU law), which continue to apply.

11. Limitation of liability

To the maximum extent permitted by applicable law, Comis, together with its owners, suppliers and licensors, will not be liable for any loss or damage arising out of or in connection with the Software, the Services or these Terms — including any indirect, incidental, special or consequential damage, or any loss of profits, business, data, goodwill or anticipated savings — whether based on contract, tort (including negligence) or any other legal theory, and whether or not we were advised of the possibility of such damage.

Nothing in these Terms excludes or limits our liability where the law does not allow it to be excluded or limited. The exclusion above therefore does not apply to: death or personal injury caused by our negligence; damage caused by our intent or gross negligence; liability under mandatory product-liability law; any guarantee we have expressly given; or any other liability that cannot lawfully be excluded. Where, in a case of slight negligence, we are liable for breach of an essential contractual obligation (one whose fulfilment is necessary to achieve the purpose of the contract and on which you may reasonably rely), our liability is limited to the foreseeable, contract-typical damage.

Subject to the foregoing and to the maximum extent permitted by law, our total aggregate liability arising out of or in connection with the Software and these Terms is limited to the total amount you actually paid for the Software (for free-tier users, who have paid nothing, our liability is limited to the fullest extent the law permits). You are responsible for maintaining backups of your data. If you are a consumer, your mandatory statutory rights are not affected by this section.

12. Indemnity

To the extent permitted by law, you will indemnify and hold Comis harmless from third-party claims, damages and costs arising from your unlawful use of the Software, your breach of these Terms, or your use of the inspection or proxy features on systems you were not authorised to access. This section does not apply to the extent a claim results from our own intentional or grossly negligent conduct, and, for consumers, applies only as far as permitted by mandatory law.

13. Term & termination

These Terms apply until terminated. Your rights under them end automatically if you materially breach them, and we may suspend or terminate your licence for breach or unlawful use. A Pro licence is otherwise perpetual. On termination you must stop using the Software and delete all copies. If a purchase is refunded, the associated licence ends and must be deactivated.

14. Changes to the Software and these Terms

We may update the Software and these Terms from time to time. We will post the current version here with an updated date and, for material changes, provide reasonable notice (for example on the website or within the app). Your continued use after changes take effect constitutes acceptance; if you do not agree, stop using the Software.

15. Governing law & jurisdiction

These Terms are governed by the laws of the Republic of Slovenia, excluding its conflict-of-laws rules and the UN Convention on Contracts for the International Sale of Goods (CISG). The courts of Ljubljana, Slovenia have jurisdiction. If you are a consumer, you also enjoy the protection of the mandatory provisions of the law of your country of residence, and nothing here deprives you of the right to bring proceedings as permitted by those mandatory rules. The European Commission’s online dispute-resolution platform is available at ec.europa.eu/consumers/odr.

16. Miscellaneous

These Terms, together with the Privacy Policy and Refund Policy, are the entire agreement between you and Comis regarding the Software. If any provision is held invalid, the remaining provisions stay in effect. Our failure to enforce a provision is not a waiver. We may assign these Terms in connection with a merger, acquisition or sale of assets; you may not assign them without our consent. We are not liable for delays or failures caused by events beyond our reasonable control. These Terms are written in English, which is the controlling language.
