Summary

Enables AI assistants to interact with Cisco Modeling Labs (CML) using natural language, allowing creation, management, and automation of network labs.

Connect from your MCP client

One-click install

Add this server to your editor with a single click. Fill in any required credentials afterward.

Claude Code

Run this once and Claude Code registers the server for you:

claude mcp add cml -- uvx cml-mcp

Claude Desktop

Add this to claude_desktop_config.json under Settings → Developer → Edit Config:

{
  "mcpServers": {
    "cml": {
      "command": "uvx",
      "args": [
        "cml-mcp"
      ],
      "env": {
        "CML_URL": "<CML_URL>",
        "CML_USERNAME": "<CML_USERNAME>",
        "CML_PASSWORD": "<CML_PASSWORD>",
        "PYATS_USERNAME": "<PYATS_USERNAME>",
        "PYATS_PASSWORD": "<PYATS_PASSWORD>",
        "PYATS_AUTH_PASS": "<PYATS_AUTH_PASS>"
      }
    }
  }
}

Cursor

Add this to .cursor/mcp.json in your project (or ~/.cursor/mcp.json for all projects):

{
  "mcpServers": {
    "cml": {
      "command": "uvx",
      "args": [
        "cml-mcp"
      ],
      "env": {
        "CML_URL": "<CML_URL>",
        "CML_USERNAME": "<CML_USERNAME>",
        "CML_PASSWORD": "<CML_PASSWORD>",
        "PYATS_USERNAME": "<PYATS_USERNAME>",
        "PYATS_PASSWORD": "<PYATS_PASSWORD>",
        "PYATS_AUTH_PASS": "<PYATS_AUTH_PASS>"
      }
    }
  }
}

Cline and other MCP clients

Most MCP clients accept the standard mcpServers JSON block:

{
  "mcpServers": {
    "cml": {
      "command": "uvx",
      "args": [
        "cml-mcp"
      ],
      "env": {
        "CML_URL": "<CML_URL>",
        "CML_USERNAME": "<CML_USERNAME>",
        "CML_PASSWORD": "<CML_PASSWORD>",
        "PYATS_USERNAME": "<PYATS_USERNAME>",
        "PYATS_PASSWORD": "<PYATS_PASSWORD>",
        "PYATS_AUTH_PASS": "<PYATS_AUTH_PASS>"
      }
    }
  }
}

Codex CLI

Register the server with OpenAI's Codex CLI — run this once, or add the equivalent block to ~/.codex/config.toml:

codex mcp add cml --env CML_URL=<CML_URL> --env CML_USERNAME=<CML_USERNAME> --env CML_PASSWORD=<CML_PASSWORD> --env PYATS_USERNAME=<PYATS_USERNAME> --env PYATS_PASSWORD=<PYATS_PASSWORD> --env PYATS_AUTH_PASS=<PYATS_AUTH_PASS> -- uvx cml-mcp

# or add to ~/.codex/config.toml:
[mcp_servers.cml]
command = "uvx"
args = ["cml-mcp"]
[mcp_servers.cml.env]
CML_URL = "<CML_URL>"
CML_USERNAME = "<CML_USERNAME>"
CML_PASSWORD = "<CML_PASSWORD>"
PYATS_USERNAME = "<PYATS_USERNAME>"
PYATS_PASSWORD = "<PYATS_PASSWORD>"
PYATS_AUTH_PASS = "<PYATS_AUTH_PASS>"

OpenClaw

OpenClaw reads MCP servers from the mcp.servers section of ~/.openclaw/openclaw.json (managed via `openclaw mcp add` or the mcporter skill):

{
  "mcp": {
    "servers": {
      "cml": {
        "command": "uvx",
        "args": [
          "cml-mcp"
        ],
        "env": {
          "CML_URL": "<CML_URL>",
          "CML_USERNAME": "<CML_USERNAME>",
          "CML_PASSWORD": "<CML_PASSWORD>",
          "PYATS_USERNAME": "<PYATS_USERNAME>",
          "PYATS_PASSWORD": "<PYATS_PASSWORD>",
          "PYATS_AUTH_PASS": "<PYATS_AUTH_PASS>"
        }
      }
    }
  }
}

Replace the <PLACEHOLDER> values with your own credentials — see the configuration table below.
