Packet Tracer MCP
Server Configuration
Describes the environment variables required to run the server.
| Name | Required | Description | Default |
|---|---|---|---|
| PT_MCP_HOST | No | IPC host; defaults to 127.0.0.1 | 127.0.0.1 |
| PT_MCP_PORT | No | IPC port; defaults to 39000 | 39000 |
| PT_MCP_APP_ID | No | Override ExApp credentials (application ID). | |
| PT_MCP_CONFIG | No | Path to local connection.json. If setup used --output-dir, set PT_MCP_CONFIG to that directory's connection.json before starting the server. | |
| PT_MCP_SECRET | No | Override ExApp credentials (secret). | |
| PT_MCP_TIMEOUT | No | Per-IPC-call timeout in seconds; defaults to 30 | 30 |
Instructions
Guidance the server publishes about itself, which clients place ahead of the tool catalog so the model reads it before choosing anything.
This server publishes no instructions, or was last inspected before Glama recorded them.

Scored across 14 tools
Each tool targets a distinct resource or action: topology export, IPC status, device listing, network lifecycle, device creation/connection, PC IPv4, IOS configuration, show output, ipconfig, ping, and time advancement. The only near-overlap is pt_ping versus pt_fast_forward, but their purposes are clearly separated by the descriptions.
All tools use a consistent pt_ prefix and snake_case, making the namespace predictable. There is minor variation between verb-led names (list_devices, create_device, configure_ios) and noun/state names (status, topology_png, pc_ipconfig), but the pattern remains readable.
Fourteen tools is well-scoped for a Packet Tracer automation server, covering connection, topology, device, configuration, and simulation operations without excessive fragmentation. Each tool appears to earn its place.
The surface covers network creation/open/save, device creation, connecting devices, configuration, and verification. However, there is no tool to delete devices or disconnect links, and no tool to list available ports/interfaces, which is a notable gap because pt_connect_devices requires knowing free ports.
