Connect from your client

Each snippet registers the same endpoint; pick the client you use.

This server is operated by the named third party. Listing and endpoint checks are not an endorsement or a security audit. Review the operator's permissions, terms, and data handling before connecting. How listings are checked and corrected.

Claude Code

Run this once in a terminal. It registers the remote server. Use --scope project to write .mcp.json for the repo.
Claude Code configuration
claude mcp add --transport http koekatsu-mcp-yomitasu https://mcp.yomitasu.jp/s/datasetsearch-jp/mcp

Codex

Run this once. Codex stores MCP servers in ~/.codex/config.toml (or .codex/config.toml in a trusted project).
Codex configuration
codex mcp add koekatsu-mcp-yomitasu --url https://mcp.yomitasu.jp/s/datasetsearch-jp/mcp

Cursor

Merge this server into .cursor/mcp.json in your project, then enable koekatsu-mcp-yomitasu in your MCP settings.
Cursor configuration
{
  "mcpServers": {
    "koekatsu-mcp-yomitasu": {
      "url": "https://mcp.yomitasu.jp/s/datasetsearch-jp/mcp"
    }
  }
