Quick Start

Run Standalone Server

# Stdio mode (for MCP clients like Claude Desktop, Cursor)
npx @agntor/mcp --stdio

# HTTP mode (for remote/hosted usage)
AGNTOR_API_KEY=your-api-key AGNTOR_SECRET_KEY=your-secret npm start

Hosted MCP

Endpoint: https://mcp.agntor.com/mcp

If authentication is enabled, include:

X-AGNTOR-API-KEY: <your_key>

Integrate with Your Application

import { createAgntorMcpServer } from '@agntor/mcp';
import { TicketIssuer } from '@agntor/sdk';

const issuer = new TicketIssuer({
  signingKey: process.env.AGNTOR_SECRET_KEY!,
  issuer: 'agntor.com',
});

const mcpServer = createAgntorMcpServer(issuer);
// Connect your transport (HTTP, stdio, WebSocket, etc.)
