**Effective date: 2025-09-02**

## Overview

These terms (“Terms”) govern your access to and use of the official MCP Registry (the service hosted at [https://registry.modelcontextprotocol.io/](https://registry.modelcontextprotocol.io/) or a successor location) (“Registry”), including submissions or publications of MCP servers, references to MCP servers or to data about such servers and/or their developers (“Registry Data”), and related conduct. The Registry is intended to be a centralized repository of MCP servers developed by community members to facilitate easy access by AI applications.

These terms are governed by the laws of the State of California.

## For All Users

1. No Warranties. The Registry is provided “as is” with no warranties of any kind. That means we don't guarantee the accuracy, completeness, safety, durability, or availability of the Registry, servers included in the registry, or Registry Data. In short, we’re also not responsible for any MCP servers or Registry Data, and we highly recommend that you evaluate each MCP server and its suitability for your intended use case(s) before deciding whether to use it.

2. Access and Use Requirements. To access or use the Registry, you must:
   1. Be at least 18 years old.
   2. Use the Registry, MCP servers in the Registry, and Registry Data only in ways that are legal under the applicable laws of the United States or other countries including the country in which you are a resident or from which you access and use the Registry, and not be barred from accessing or using the Registry under such laws. You will comply with all applicable law, regulation, and third party rights (including, without limitation, laws regarding the import or export of data or software, privacy, intellectual property, and local laws). You will not use the Registry, MCP servers, or Registry Data to encourage or promote illegal activity or the violation of third party rights or terms of service.
   3. Log in via method(s) approved by the Registry maintainers, which may involve using applications or other software owned by third parties.

3. Entity Use. If you are accessing or using the Registry on behalf of an entity, you represent and warrant that you have authority to bind that entity to these Terms. By accepting these Terms, you are doing so on behalf of that entity (and all references to “you” in these Terms refer to that entity).

4. Account Information. In order to access or use the Registry, you may be required to provide certain information (such as identification or contact details) as part of a registration process or in connection with your access or use of the Registry or MCP servers therein. Any information you give must be accurate and up-to-date, and you agree to inform us promptly of any updates. You understand that your use of the Registry may be monitored to ensure quality and verify your compliance with these Terms.

5. Feedback. You are under no obligation to provide feedback or suggestions. If you provide feedback or suggestions about the Registry or the Model Context Protocol, then we (and those we allow) may use such information without obligation to you.

6. Branding. Only use the term “Official MCP Registry” where it is clear it refers to the Registry, and does not imply affiliation, endorsement, or sponsorship. For example, you can permissibly say “Acme Inc. keeps its data up to date by automatically pulling data from the Official MCP Registry” or “This data comes from the Official MCP Registry,” but cannot say “This is the website for the Official MCP Registry,” “We’re the premier destination to view Official MCP Registry data,” or “We’ve partnered with the Official MCP Registry to provide this data.”

7. Modification. We may modify the Terms or any portion to, for example, reflect changes to the law or changes to the Model Context Protocol. We’ll post notice of modifications to the Terms to this website or a successor location. If you do not agree to the modified Terms, you should discontinue your access to and/or use of the Registry. Your continued access to and/or use of the Registry constitutes your acceptance of any modified Terms.

8. Additional Terms. Depending on your intended use case(s), you must also abide by applicable terms below.

## For MCP Developers

9. Prohibitions. By accessing and using the Registry, including by submitting MCP servers and/or Registry Data, you agree not to:
   1. Share malicious or harmful content, such as malware, even in good faith or for research purposes, or perform any action with the intent of introducing any viruses, worms, defects, Trojan horses, malware, or any items of a destructive nature;
   2. Defame, abuse, harass, stalk, or threaten others;
   3. Interfere with or disrupt the Registry or any associated servers or networks;
   4. Submit data with the intent of confusing or misleading others, including but not limited to via spam, posting off-topic marketing content, posting MCP servers in a way that falsely implies affiliation with or endorsement by a third party, or repeatedly posting the same or similar MCP servers under different names;
   5. Promote or facilitate unlawful online gambling or disruptive commercial messages or advertisements;
   6. Use the Registry for any activities where the use or failure of the Registry could lead to death, personal injury, or environmental damage;
   7. Use the Registry to process or store any data that is subject to the International Traffic in Arms Regulations maintained by the U.S. Department of State.

10. License. You agree that metadata about MCP servers you submit (e.g., schema name and description, URLs, identifiers) and other Registry Data is intended to be public, and will be dedicated to the public domain under [CC0 1.0 Universal](https://creativecommons.org/publicdomain/zero/1.0/). By submitting such data, you agree that you have the legal right to make this dedication (i.e., you own the copyright to these submissions or have permission from the copyright owner(s) to do so) and intend to do so. You understand that this dedication is perpetual, irrevocable, and worldwide, and you waive any moral rights you may have in your contributions to the fullest extent permitted by law. This dedication applies only to Registry Data and not to packages in third party registries that you might point to.

11. Privacy and Publicity. You understand that any MCP server metadata you publish may be made public. This includes personal data such as your GitHub username, domain name, or details from your server description. Moreover, you understand that others may process personal information included in your MCP server metadata. For example, subregistries might enrich this data by adding how many stars your GitHub repository has, or perform automated security scanning on your code. By publishing a server, you agree that others may engage in this sort of processing, and you waive rights you might have in some jurisdictions to access, rectify, erase, restrict, or object to such processing.
