cisco-pt-mcp

Let AI clients control a running Cisco Packet Tracer instance. Open source.

Demo

Install

Two components. Five minutes.

1. MCP Server

Install uv if you don't have it, then register with your client:

Claude Code

claude mcp add cisco-pt-mcp --scope user -- uvx cisco-pt-mcp

Cursor (~/.cursor/mcp.json or .cursor/mcp.json per project)

{
  "mcpServers": {
    "cisco-pt-mcp": { "command": "uvx", "args": ["cisco-pt-mcp"] }
  }
}

VS Code (.vscode/mcp.json)

{
  "servers": {
    "cisco-pt-mcp": {
      "type": "stdio",
      "command": "uvx",
      "args": ["cisco-pt-mcp"]
    }
  }
}

Codex CLI (~/.codex/config.toml)

[mcp_servers.cisco-pt-mcp]
command = "uvx"
args = ["cisco-pt-mcp"]

2. Packet Tracer Extension

Open Packet Tracer.
Go to Extensions → Scripting → Configure PT Script Modules…
Click Add and select cisco-pt-mcp.pts.
Restart Packet Tracer.

3. Run

Click Extensions → Packet Tracer MCP to open the bridge window, then start your MCP client. The status pill flips to connected within a second. Start prompting.
