What it does
Provides prebuilt integrations so an assistant can work with Gmail, Slack, GitHub and a hundred-plus other services, including the OAuth plumbing, instead of you writing each connection yourself. This hands an AI real permissions on real accounts: grant read-only access first and understand exactly what is enabled before allowing it to send mail or delete files. A paid hosted tier exists alongside the open-source pieces.
Summary based on the project's own description. The Japanese page has a fuller beginner guide: setup difficulty, what to prepare, and a step-by-step start.

klavis FAQ
- Is klavis free?
- klavis itself is free, but it needs an API key for an external AI service. That service charges separately, though some have a free tier.
- Do I need to install anything or write code to use klavis?
- It connects to an MCP-capable AI app such as Claude. It does not run on its own.
- Does klavis work on a phone?
- No. It needs a computer.
- Can I use klavis commercially?
- The licence is Apache-2.0, which permits commercial use. Conditions such as keeping the copyright notice still apply, so read the licence text before shipping it inside something.
