Packet Tracer Mcp
Let your coding agent drive Cisco Packet Tracer 9 labs for routing, switching, and security scenarios instead of clicking through the GUI alone.
Overview
Packet Tracer MCP is a Build-phase MCP server that lets AI agents control Cisco Packet Tracer 9 labs over a local bridge for live IOS and routing-protocol scenarios.
What is this MCP server?
- stdio MCP server (npm package packet-tracer-mcp, runtime hint Bun) talking to Packet Tracer 9
- Internal HTTP bridge on BRIDGE_PORT (default 54321) to the Packet Tracer webview
- Live IOS-style configuration workflows across OSPF, BGP, NAT, VLAN, VoIP, QoS, IPv6, and wireless topics
- Suited to CCNA/CCNP-style practice and agent-assisted topology experiments
- Version 0.1.1 with GitHub source at Jcorderop02/packet-tracer-mcp
- Server version 0.1.1
- Default BRIDGE_PORT 54321
- Documented protocol areas: IOS, OSPF, BGP, NAT, VLAN, VoIP, QoS, IPv6, wireless
What problem does it solve?
Repeating Packet Tracer labs and CLI steps by hand slows learning and makes it hard for an agent to help you debug routing or VLAN mistakes in real time.
Who is it for?
Network learners, homelab builders, and indie educators who already use Packet Tracer 9 and want agent-assisted lab automation on a single machine.
Skip if: Teams that need production Cisco hardware automation, cloud IaC-only workflows, or builders without Packet Tracer 9 installed.
What do I get? / Deliverables
After you register the stdio server and bridge port, your agent can drive Packet Tracer 9 workflows while you focus on design decisions and documentation.
- Registered stdio MCP server wired to Packet Tracer 9 via BRIDGE_PORT
- Agent-accessible lab actions across listed routing, switching, and wireless topics
- Repeatable simulation sessions for documentation or coursework
Recommended MCP Servers
Journey fit
Network lab automation plugs into the build phase when you are wiring agent workflows to real tooling and validating infrastructure designs before production. It is an MCP bridge to Packet Tracer’s webview, which is classic agent-tooling integration rather than app feature code.
How it compares
MCP lab bridge for Packet Tracer 9, not a cloud deployment skill or generic browser scraper.
Common Questions / FAQ
Who is Packet Tracer MCP for?
It is for developers and students who run Cisco Packet Tracer 9 locally and want Claude Code, Cursor, or Codex to help configure simulated networks through MCP.
When should I use Packet Tracer MCP?
Use it during build and integration experiments when you are practicing or demonstrating OSPF, BGP, NAT, VLAN, VoIP, QoS, IPv6, or wireless topologies inside Packet Tracer.
How do I add Packet Tracer MCP to my agent?
Install the npm package packet-tracer-mcp, run it with stdio transport, set BRIDGE_PORT if needed (default 54321), start Packet Tracer 9’s webview, and add the server entry in your MCP client config.
