ワットク(Wattoku) is a Model Context Protocol (MCP) server: Compare Japan's household fixed costs: electricity, city gas and fiber plans, and simulate bundles. In practice that means any MCP-compatible AI assistant can call ワットク(Wattoku)'s tools directly — the model decides when to use them in a conversation or agent run.
It's a hosted (remote) server — point your client at https://wattoku.meliorra.co/api/mcp and you're connected, with nothing to install locally. The current release is v1.2.0.
ワットク(Wattoku) is listed under Development on mcp.site and works with any MCP client — Claude Desktop, Claude Code, Cursor, VS Code, Windsurf, Zed and the rest of the ecosystem — using the install snippets below.
