Experiment with the Claude Connector Directory

PreVibe has had an MCP server almost from the start because MCP is a good interface for AI agents. Treat it like a modern REST API, made specifically for agents.

This week I submitted PreVibe MCP to the Claude Connector Directory, and I'd like to share my results.

1. Some stats first... During the first 2 days after approval, I got ~60 site registrations (with Google), at least half of them connected to the MCP, ~10 performed research at least one time (1 is free), 3 bought credit packs.

2. I've improved MCP tool declarations to comply with the directory, added intro instructions for agents and created a validate-idea prompt to simplify the onboarding.

3. The number of new registrations went down in two days after publication. I heard the same from other publishers too. It can mean that Anthropic has a list of New connectors which they somehow somewhere promote, and as time passes, other new connectors just push you down the list and people stop seeing you.

4. I've realized that I need to keep spreading the word about the MCP, so I added it to the official MCP registry, which is used by other MCP directories as a source. I've also submitted PreVibe MCP to a bunch of other free directories, some of them have already approved it and made the MCP page public. Most of them add rel=nofollow for your links until you sign up for a paid plan though, but it's better than nothing, right?

5. To be able to maintain the Claude directory listing, I think I have to keep the Team plan active (-$50/mo). I haven't yet broken even, but I think the experiment went very well. Some people paid right after they tried the service, which could mean that they were satisfied with the reports they got.

That's it for now. Hope you find my experience useful.
