Netmiko

An MCP (Model Context Protocol) server for managing network devices via SSH using Netmiko. Features connection pooling, multi-vendor support, and concurrent operations.

Features

• Command Execution: Run CLI commands on single or multiple devices
• Configuration Management: Push configuration changes with optional save/rollback
• Device Inventory: YAML-based device inventory with groups and tags
• Connection Pooling: Efficient connection reuse with health checks
• Multi-Vendor Support: Works with any device type supported by Netmiko
• Concurrent Operations: Execute commands on multiple devices in parallel
• TextFSM Parsing: Optional structured output parsing

Installation

From Source

git clone https://github.com/ntunes/netmiko-mcp-server.git
cd netmiko-mcp-server
pip install -e .

With Docker

docker build -t netmiko-mcp .

Configuration

Device Inventory

Create a config/devices.yaml file with your device inventory:

defaults:
  timeout: 30
  fast_cli: true

credentials:
  production:
    username: "${NETMIKO_USERNAME}"
    password: "${NETMIKO_PASSWORD}"
    secret: "${NETMIKO_SECRET}"

groups:
  core_routers:
    - core-rtr-01
    - core-rtr-02

devices:
  core-rtr-01:
    host: "192.168.1.1"
    device_type: "cisco_ios"
    credential_profile: "production"
    tags:
      - core
      - production

  core-rtr-02:
    host: "192.168.1.2"
    device_type: "cisco_ios"
    credential_profile: "production"
    tags:
      - core
      - production

pool_settings:
  max_connections_per_device: 3
  connection_timeout: 300
  health_check_interval: 60

Environment Variables

Set credentials via environment variables:

export NETMIKO_USERNAME="admin"
export NETMIKO_PASSWORD="your_password"
export NETMIKO_SECRET="enable_secret"

Optionally set config file location:

export NETMIKO_MCP_CONFIG="/path/to/devices.yaml"

Usage

Running the Server

Stdio transport (for Claude Desktop):

python -m netmiko_mcp

Streamable HTTP transport:

python -m netmiko_mcp --transport streamable-http --port 8339

With Docker:

docker run -p 8339:8339 \
  -e NETMIKO_USERNAME=admin \
  -e NETMIKO_PASSWORD=secret \
  -v ./config/devices.yaml:/app/config/devices.yaml:ro \
  netmiko-mcp

With Docker Compose:

# Set credentials in .env or environment
export NETMIKO_USERNAME=admin
export NETMIKO_PASSWORD=secret

docker-compose up -d

Claude Desktop Configuration

Add to your Claude Desktop configuration:

For stdio transport:

{
  "mcpServers": {
    "netmiko": {
      "command": "python",
      "args": ["-m", "netmiko_mcp", "--config", "/path/to/devices.yaml"]
    }
  }
}

For HTTP transport:

{
  "mcpServers": {
    "netmiko": {
      "url": "http://localhost:8339/mcp"
    }
  }
}

MCP Tools

Command Execution

send_commands_sequence	Execute multiple commands sequentially on one device

Configuration

Tool	Description
send_config	Push configuration commands to one device
send_config_parallel	Push configuration to multiple devices concurrently

Inventory & Discovery

Tool	Description

Examples

Execute a command:

Use send_command on device "core-rtr-01" with command "show version"

Execute on multiple devices:

Use send_command_parallel on devices ["@core_routers"] with command "show ip interface brief"

Push configuration:
