Cubeshell gives Claude and Codex the superpowers to run your sales, outreach and GTM motion through one MCP connection. Connect it, and let your agent research companies, find and verify contacts, track job changes, discover open roles and handle your sales research in one place. No separate API accounts or monthly subscriptions for every tool. Connect once, use what you need and only pay when a tool runs.

To run my business, I need a lot of different tools. But I rarely use most of them enough to justify paying for a full subscription every month. Some months I’m focused on implementation, so I barely use tools for sales, marketing, research, or outreach. Then my focus changes and I need them again. Paying for everything all the time just doesn’t make sense. So I built cubeshell.com. Right now, Cubeshell can find and verify emails, mobile numbers, people, company contacts, similar companies and job listings. It can also research people and companies, look up technologies, check job changes and scrape web pages. I’ll keep adding more tools over time. You connect Cubeshell once to Claude, Codex, or any other AI agent that supports MCP. Then you use the tools when you need them and only pay for what you use. It solves a real problem for me, and it will solve it for many of you too.

Finally! This is exactly what I needed. I run a lot of B2B automation work, and the subscription bloat is ridiculous. I've got all these tools sitting idle most months, just eating into margins. Having everything accessible through one MCP connection to Claude is such a breath of fresh air. Just tried the job tracking feature and it's solid. Definitely signing up. This feels like it was built for people who actually do this work, not just another tool trying to be everything.
