Nornir FAQs

Question 1

What is Nornir MCP Server?

Accepted Answer

Nornir MCP Server is a Model Context Protocol (MCP) server that acts as a bridge, enabling AI assistants (LLMs) to directly interact with network devices. It uses Nornir, NAPALM, and Netmiko to query inventory, retrieve real-time operational data, and execute commands through a standardized interface.

Question 2

Is Nornir MCP Server safe for network changes?

Accepted Answer

The `run_napalm_getter` tool is strictly read-only. The `run_netmiko_command` tool can execute configuration commands, offering powerful capabilities but requiring careful usage. Security of Nornir inventory credentials is paramount, and testing in a lab environment is recommended.

Question 3

Which network automation technologies does it integrate with?

Accepted Answer

The server is built upon Nornir for inventory management and concurrency, NAPALM for vendor-agnostic data retrieval, and Netmiko for robust CLI command execution. It provides a standardized MCP interface for AI consumption.

Question 4

How do I configure Nornir MCP Server?

Accepted Answer

Configuration requires a standard Nornir `config.yaml` file, which can be specified via the `NORNIR_CONFIG_FILE` environment variable or placed in the current working directory. For AI assistant integration, such as with Claude, you configure the server command and environment variables in your `.claude.json` or `.mcp.json` file.

Question 5

What capabilities does Nornir MCP Server provide?

Accepted Answer

It allows AI assistants to list and filter network inventory, fetch deep device insights (like facts, interfaces, ARP tables) using NAPALM getters, and execute any raw CLI command on devices with Netmiko. You can target specific devices or entire groups for these operations.
