Custom integrations and MCP servers

We build connections between business software and AI assistants, and between business systems. This site is our own work: 455 hosted MCP servers, each with its tools, a secure sign-in, usage limits and billing, built and run by us.

What we build

How it works

  1. Email us what you want to connect, and what the AI assistant or the system must do. Include the systems involved, an example workflow with its inputs and outputs, the API access you have, your target date, and any hosting or data requirements.
  2. We reply with our questions. Then we send a written scope and a price, before any work starts.
  3. We build and test it, and deliver it to you. If you want, we also maintain it.

Before we build on a vendor's API, we check the vendor's API terms.

Contact

Email [email protected] with the subject "Custom work".

For paid custom work, email us. For a suggestion about one of our hosted servers, ask your AI assistant to use the server's request_feature tool (for example rotacloud_request_feature). We read every suggestion, but a suggestion does not order work and does not guarantee that we build it.
