NPM package @agntor/mcp
Claude Code 
claude mcp add trust -e 'AGNTOR_API_KEY=<your agntor_api_key>' -e 'AGNTOR_SECRET_KEY=<your agntor_secret_key>' -- npx -y @agntor/mcp@0.1.0
JSON configuration (Claude Desktop, Cursor, VS Code)

Cline (VSCode Extension)

Edit ~/.cline/mcp.json:

{
  "mcpServers": {
    "agntor": {
      "command": "npx",
      "args": ["-y", "@agntor/mcp"]
    }

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.)
