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}"
}
}
}
