Agent Passport System MCP Server

MCP server for the Agent Passport System — cryptographic identity, delegation, governance, and commerce for AI agents.

61 tools across all 17 protocol modules. Works with any MCP client: Claude Desktop, Cursor, Windsurf, and more.

Quick Start

Remote (no install)

Connect directly via SSE — works with any MCP client:

{
  "mcpServers": {
    "agent-passport": {
      "type": "sse",
      "url": "https://mcp.aeoess.com/sse"
    }
  }
}

Claude Desktop (local)

Add to ~/Library/Application Support/Claude/claude_desktop_config.json:

{
  "mcpServers": {
    "agent-passport": {
      "command": "npx",
      "args": ["agent-passport-system-mcp"]
    }
  }
}

Cursor / Windsurf

Add to your MCP config:

{
  "mcpServers": {
    "agent-passport": {
      "command": "npx",
      "args": ["agent-passport-system-mcp"]
    }
  }
}
