Containerlab MCP Server

What is Containerlab MCP Server?

Containerlab MCP Server is an experimental Model Context Protocol server that enables AI assistants (such as Claude) to interact with containerlab network topologies. It is tailored for use with Claude Desktop and requires a running containerlab API server.

How to use Containerlab MCP Server?

Build the MCP server binary for your platform (Windows, Mac, or Linux) using go build, then configure Claude Desktop by placing the executable and adding a claude_desktop_config.json that sets the API_SERVER_URL environment variable (default http://localhost:8080). Ensure the containerlab API server is running.

FAQ from Containerlab MCP Server

What dependencies are required?

You need a running containerlab API server and the latest build of containerlab from the main branch. The MCP server is a compiled Go binary.

What transport does the server use?

The server communicates with the containerlab API server via HTTP, using the API_SERVER_URL environment variable (default http://localhost:8080).

Where do lab configurations and data live?

Lab topologies and state are managed by containerlab itself. The MCP server acts only as a proxy to the API server; no lab data is stored by the MCP server.

Is authentication supported?

The README does not mention any authentication mechanism. The server is intended for local use.

Is this ready for production?

No. The README describes this as a "quick and dirty trial" for exploring MCP with containerlab. It is experimental.
