Use Cyphrex with your AI

The MCP server is https://mcp.cyphrex.io/mcp. Send your own API key as Authorization: Bearer ${CYPHREX_API_KEY}. Do not put the key in tool arguments, chat, or git.

Accounts come only from a paid plan or the free 2-week trial on Plans. The trial ends with a day-14 risk report. There is no open sign-up.

Cursor

Install the Cyphrex Cursor plugin from https://github.com/getcyphrex/cyphrex-cursor-plugin. Then open Plugins, Configure, and set CYPHREX_API_KEY. The plugin sends that value as the Bearer token.

Plain ~/.cursor/mcp.json, if you are not using the plugin:

{
  "mcpServers": {
    "cyphrex": {
      "url": "https://mcp.cyphrex.io/mcp",
      "headers": {
        "Authorization": "Bearer ${CYPHREX_API_KEY}"
      }
    }
  }
}

Claude

Claude Desktop and Claude Code use the same mcpServers entry:

{
  "mcpServers": {
    "cyphrex": {
      "url": "https://mcp.cyphrex.io/mcp",
      "headers": {
        "Authorization": "Bearer ${CYPHREX_API_KEY}"
      }
    }
  }
}

ChatGPT

Add a custom MCP connector. Server URL: https://mcp.cyphrex.io/mcp. Header: Authorization: Bearer ${CYPHREX_API_KEY}.
