npm install node-fetch@2

rm -rf dist

npm run build



## Install mcp packet tracer - continue

cd ~/MCP-PT

source mcp-pkt/bin/activate

pip install -e . => install using local python file

python -m packet_tracer_mcp --stdio

**if working, no error message. Control-C to exit


## 5)Install Packet Tracer

Download from Cisco Netacad

cd ~/Downloads

sudo apt install ./CiscoPacketTracer_901_Ubuntu_64bit.deb



# If import given OVA, OVA comes with all the above installed

Start claude-desktop and login for claude to generate the claude_desktop_config.json.

Shutdown claude-desktop before doing the steps below.


cd MCP-PT

source mcp-pkt/bin/activate



nano /home/analyst/.config/Claude/claude_desktop_config.json
```
  "mcpServers": {
    "ollama": {
      "command": "node",
      "args": ["/home/analyst/mcp-ollama/dist/index.js"],
      "env": {
        "OLLAMA_BASE_URL": "http://< VM_IP_ADDRESS>:11434"
      }
    }
  },
```
**When using claude-desktop, no way to choose the model, must specify in the prompt such as

"Use the Ollama MCP server to list the available Ollama models.

Use qwen2.5:3b through Ollama to answer my next networking question."


or

"Use the Ollama MCP server and ask qwen2.5:3b:

Explain how to configure a VLAN on a Cisco IOS switch."


nano /home/analyst/.config/Claude/claude_desktop_config.json

Do this on the Ubuntu machine where you run packet_tracer_mcp:

cd MCP-PT

source mcp-pkt/bin/activate


echo "$PT_MCP_BRIDGE_TOKEN"

If it is empty, generate one:

export PT_MCP_BRIDGE_TOKEN=$(python3 -c "import secrets; print(secrets.token_urlsafe(32))")


Need to ask the prompt

"Use the Packet Tracer MCP tool pt_bridge_status and tell me the connection status."

To allow the connection from claude desktop


# How to start the system

cd MCP-PT

source mcp-pkt/bin/activate

export PT_MCP_BRIDGE_TOKEN=$(python3 -c "import secrets; print(secrets.token_urlsafe(32))")

python -m packet_tracer_mcp --stdio

open another terminal (don’t start claude from menu)

claude-desktop

import packet tracer skill into claude

start packet tracer

if MCP control center still not connected,

send a prompt in claude-desktop

“Use the ollama MCP and Packet Tracer MCP tool pt_bridge_status and tell me the connection status.”

Restart packet
