About this server

Buyer-side fair-price checks for Japanese renovation quotes; cost data is on a separate server.

Install horizon-shield

The server’s own address, for the clients that take one directly. Or connect ahel once and every client you use reads it from one address, with the account kept on ahel rather than in each client’s config.

Claude Code
claude mcp add --transport http --scope user horizon-shield 'https://mcp.horizonshield.dev/mcp'
Run it once in your project, then open /mcp to approve any sign-in the server asks for.
Claude Desktop
https://mcp.horizonshield.dev/mcp
Add a custom connector in Settings, paste this address, and approve the sign-in.
Cursor
cursor://anysphere.cursor-deeplink/mcp/install?name=horizon-shield&config=eyJ1cmwiOiJodHRwczovL21jcC5ob3Jpem9uc2hpZWxkLmRldi9tY3AifQ==
Open the link and Cursor adds the server at that address.
ChatGPT
https://mcp.horizonshield.dev/mcp
In Settings, enable Developer mode, create an MCP app, and paste this address. Your plan and workspace must allow custom apps.
Codex
codex mcp add horizon-shield --url 'https://mcp.horizonshield.dev/mcp'
Run it once, then sign in with codex mcp login horizon-shield if the server asks for an account.
