Claude Code

Run this once in a terminal. It registers a Streamable HTTP server. Use --scope project to write .mcp.json for the repo.

Claude Code configuration

claude mcp add --transport http registercheck-mcp https://mcp.registercheck.de/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 registercheck-mcp --url https://mcp.registercheck.de/mcp

Cursor

Merge this server into .cursor/mcp.json in your project, then enable registercheck-mcp in your MCP settings.

Cursor configuration

{
  "mcpServers": {
    "registercheck-mcp": {
      "url": "https://mcp.registercheck.de/mcp"
    }
  }
}

Cline

Merge this into cline_mcp_settings.json (Cline → MCP Servers → Configure). The type must be streamableHttp for a remote HTTP server.
