Let an autonomous AI agent diagnose and fix your Cisco Packet Tracer networks in real-time. Build labs, inject faults, and watch AI find the root cause — all through MCP.
npx -y @ankitrajput07/packet-tracer-mcp
From building topologies to diagnosing multi-fault scenarios — all through natural language.
AI inspects live topology, reads device configs, checks VLANs, pings endpoints, and identifies the exact root cause — all autonomously.
Add routers, switches, PCs. Create links. Configure IPs. All through natural language commands to AI.
AI makes the minimum necessary change. No rebuilding. No guesswork. Evidence-based repair with verification.
VLAN config, OSPF/EIGRP/BGP routing, ACLs, NAT, VoIP, QoS, IPv6, Wireless — everything Cisco, all via AI.
Introduce controlled faults (wrong gateway, VLAN mismatch) and test your AI agent's troubleshooting ability.
Three components connected through the Model Context Protocol (MCP).

Simulates Hardware"PC1 cannot communicate with PC2" — just tell the AI in natural language what's wrong.
The AI calls MCP tools like pt_inspect_ports, pt_read_vlans, pt_ping to gather real evidence from Packet Tracer.
By analyzing the evidence (not guessing), AI determines the exact fault — wrong VLAN, bad gateway, missing route.
One precise configuration change. No rebuilding. AI uses pt_apply_switching, pt_set_pc, or pt_run_cli_bulk to repair.
Ping tests confirm connectivity. AI doesn't claim success without proof. 100% evidence-based.
Three prerequisites. One config line. That's it.
