Claude Code & Cursor

Add RedReplier as an HTTP MCP server. Paste the config into your client's MCP settings and replace the placeholder with your API key.

MCP config

{
  "mcpServers": {
    "redreplier": {
      "type": "http",
      "url": "https://mcp.redreplier.com/mcp",
      "headers": {
        "Authorization": "Bearer redreplier_your_api_key_here"
      }
    }
  }
}

Create an API key in API tokens. Keys start with redreplier_.

Claude Code CLI

claude mcp add --transport http --scope project --header "Authorization: Bearer redreplier_your_api_key_here" -- redreplier https://mcp.redreplier.com/mcp
