Cisco Catalyst SD WAN Server

Model Context Protocol (MCP) server for Cisco Catalyst SD-WAN Manager (vManage). It exposes vManage REST API capabilities as MCP tools, allowing AI assistants to query and manage SD-WAN fabric through vManage. SD-WAN routers are accessed only via vManage—no direct router communication.

Features

• 39 MCP tools covering device management, real-time monitoring, templates, policies, CloudExpress, and administration
• Dual authentication: JWT (recommended for vManage 20.18.1+) and session-based (JSESSIONID) fallback
• Docker support for containerized deployment
• HTTPS on port 443 by default for vManage communication

Prerequisites

• Node.js 18+
• Access to a Cisco Catalyst SD-WAN Manager (vManage) instance
• vManage credentials with appropriate API permissions

Configuration

Environment Variables

Variable	Required	Default	Description
VMANAGE_HOST	Yes	-	vManage hostname or IP address
VMANAGE_USERNAME	Yes	-	vManage username
VMANAGE_PASSWORD	Yes	-	vManage password
VMANAGE_PORT	No	443	vManage HTTPS port
VMANAGE_USE_JWT	No	true	Use JWT auth (set false for session-based)

Cursor MCP Configuration

Add to your Cursor MCP settings (e.g. ~/.cursor/mcp.json or project .cursor/mcp.json):

Using Docker:

{
  "mcpServers": {
    "catalyst-sdwan": {
      "command": "docker",
      "args": [
        "run",
        "-i",
        "--rm",
        "-e", "VMANAGE_HOST=your-vmanage.example.com",
        "-e", "VMANAGE_PORT=443",
        "-e", "VMANAGE_USERNAME=admin",
        "-e", "VMANAGE_PASSWORD=your_password",
        "catalyst-sdwan-mcp:latest"
      ]
    }
  }
}

Using Node.js directly:

{
  "mcpServers": {
    "catalyst-sdwan": {
      "command": "node",
      "args": ["/path/to/catalyst-sdwan-mcp/build/index.js"],
      "env": {
        "VMANAGE_HOST": "your-vmanage.example.com",
        "VMANAGE_PORT": "443",
        "VMANAGE_USERNAME": "admin",
        "VMANAGE_PASSWORD": "your_password"
      }
    }
  }
}

Docker

Build

cd catalyst-sdwan-mcp
docker build -t catalyst-sdwan-mcp:latest .

Run with docker-compose

docker run -i --rm \
  -e VMANAGE_HOST=10.1.1.1 \
  -e VMANAGE_PORT=443 \
  -e VMANAGE_USERNAME=admin \
  -e VMANAGE_PASSWORD=secret \
  catalyst-sdwan-mcp:latest

Authentication

The server supports two authentication methods per Cisco Catalyst SD-WAN Manager API docs:

1. JWT (recommended) - For vManage 20.18.1+. Single login returns access token and XSRF token. Set VMANAGE_USE_JWT=true (default).

2. Session-based - Legacy method. POST to /j_security_check for JSESSIONID, then GET /dataservice/client/token for XSRF. Set VMANAGE_USE_JWT=false.

All API requests use HTTPS. Self-signed certificates (common in lab environments) are accepted; for production, use properly signed certificates.
