io.github.Kotaro-Studio/curanz-sounds

io.github.Kotaro-Studio/curanz-sounds in the official MCP registry. Endpoint https://curanzsounds.com/mcp. Source: github.com/Kotaro-Studio/curanz-sounds.

The registry describes it as: 生年月日から占いを計算して答える。星座・九星気学の本命星と年盤・四柱推命の日干と流年・天中殺・数秘術の個人年。出生時刻は不要。古典の暦法による計算。

We read its 1 tool on 2026-10-28. Nothing in it matched our tool-poisoning rules. It also sets server instructions, text a client puts in front of the model on connect; those were read too.

A clean read means these rules found nothing, not that the server is harmless. A server can change its tools at any time, which is why the index reads it again every week.

Connect it

The endpoint answers MCP over HTTP; that is how we read it. Add it to your client:

Claude Code

claude mcp add --transport http curanz-sounds https://curanzsounds.com/mcp

Cursor: ~/.cursor/mcp.json

{
  "mcpServers": {
    "curanz-sounds": {
      "url": "https://curanzsounds.com/mcp"
    }
  }
}

VS Code

code --add-mcp '{"name":"curanz-sounds","type":"http","url":"https://curanzsounds.com/mcp"}'

Some servers ask you to sign in the first time a client connects, or want a key from the people who run them; the server's own docs say which. The free lazaretto-guard plugin reads a server's tools the moment Claude Code adds it and asks you if one of our rules matches.

How this was checked

Lazaretto connects to the endpoint the way any MCP client does, asks the server to introduce itself and list its tools, and reads every name, description, parameter schema and server instruction for tool poisoning: hidden directive blocks, orders to read local secrets, parameters built to carry secrets or the conversation out, orders that redirect another server's tools, and invisible characters. It never calls a tool. What we found across the registry.
