AI agent and MCP registries
MCP registries and AI assistant directories are how people find tools to plug into Claude, ChatGPT, Cursor and other agents. Start with the Official MCP Registry, which several directories read from, then add the assistant directories whose users you want. Those review submissions closely, especially tool annotations and authentication.
How to use AI agent and MCP registries
- Publish the package and its entry in the Official MCP Registry first, then submit to directories.
- Give every tool a clear title and the right read-only or destructive annotation before any directory review.
- Prepare a test account a reviewer can use end to end, without MFA or email codes.
