MCP-Packet-Tracer

Overview

This MCP server enables AI assistants to programmatically control Cisco Packet Tracer, translating natural language prompts into complete network topologies. It provides 30 tools covering the entire workflow from planning to deployment, including IP addressing, routing protocols (OSPF, EIGRP, RIP), DHCP setup, ACLs, and NAT/PAT. The server bridges to Packet Tracer via HTTP for live deployment, eliminating manual copy-paste. With 74 device models, 151 modules, and 15 cable types supported, it covers a wide range of network scenarios.

FAQ

What Cisco Packet Tracer versions are supported?

The server works with any modern Packet Tracer version that supports the PTBuilder API (:54321). This includes Packet Tracer 8.2 and later.

Can I use this with other network simulators?

Currently, this server is specifically designed for Cisco Packet Tracer and uses its proprietary PTBuilder API for direct deployment. Other simulators would require a different implementation.
