How to use
  • Install
git clone https://github.com/upa/mcp-netmiko-server
cd mcp-netmiko-server

# Write your toml file that lists your devices
vim my-devices.network.toml

# Run via stdio
uv run --with "mcp[cli]" --with netmiko main.py my-devices.network.toml

# Run as an SSE server: URL is http://localhost:10000/sse in this case
uv run --with "mcp[cli]" --with netmiko main.py my-devices.network.toml --sse
  • Configuration

List your network devices in a toml file like sample.network.toml:

[default]

username = "rouser"
password = "rouserpassword"

[qfx1]

hostname = "172.16.0.40"
device_type = "juniper_junos"

[nexus1]

hostname = "nexus1.lab"
device_type = "cisco_nxos"

[default] is a special section that defines the default values such as username and password. Devices inherit the default values if not defined on their sections.

For device_type values, see netmiko Supported Platforms.
