リモート Model Context Protocol (MCP) サーバー for kintone via OAuth on Cloudflare Workers

What is リモート Model Context Protocol (MCP) サーバー for kintone via OAuth on Cloudflare Workers?

This server allows AI assistants like Claude to securely access kintone (Cybozu’s cloud database service) through the Model Context Protocol (MCP). Deployed on Cloudflare Workers, it uses OAuth authentication—no local credential storage is needed. It is designed for users of a single cybozu.com domain who want to share a single MCP server instance without local setup.

How to use リモート Model Context Protocol (MCP) サーバー for kintone via OAuth on Cloudflare Workers?
