Installation

Prerequisites

• Node.js 18+ and npm

• Access to a Cisco APIC controller

• Valid APIC credentials (username/password or certificate)

Setup

1. Clone and Install:

   cd aci-mcp-server npm install

2. Configure Authentication:

   Option A: Environment Variables

   cp .env.example .env # Edit .env with your APIC details export ACI_APIC_URL="https://your-apic.domain.com" export ACI_USERNAME="admin" export ACI_PASSWORD="your_password"

   Option B: Configuration Files

   cp aci-config.json.example aci-config.json # Edit aci-config.json with your settings

   Option C: Certificate Authentication

   export ACI_APIC_URL="https://your-apic.domain.com" export ACI_USERNAME="admin" export ACI_CERT_NAME="your-cert-name" export ACI_PRIVATE_KEY_PATH="/path/to/private.key"

3. Build the Server:

   npm run build

4. Test Connection:

   npm start # Should connect to APIC and display available tools

Configuration

Authentication Methods

The server supports two authentication methods:

1. Username/Password: Standard APIC login
