Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00082 | $0.01692 |
| Opus 5 | $0.00041 | $0.00846 |
| Sonnet 5 | $0.00016 | $0.00338 |
| Haiku 4.5 | $0.00008 | $0.00169 |
Grade A, and why
pt-visual-mcp scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 9d ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
How it starts
The opening of the file, as written. The whole thing — 136 lines — stays where its author put it; the contents beside it link to each section on GitHub.
PT Visual MCP
This skill drives the original packet-tracer-visual-mcp toolchain: a local MCP server plus a Packet Tracer extension bridge. It is optimized for Packet Tracer lab generation, IOS automation, course-design topologies, and optional visual topology building.
Default local checkout on this machine: E:\mc\packet-tracer-visual-mcp.
Before Acting
- Check whether the MCP tool list contains
ptv_bridgeStatus. - If it is missing, tell the user the PT Visual MCP tools are not loaded and ask them to restart Codex after adding the MCP config.
- If it is loaded, call
ptv_bridgeStatusfirst. - If the bridge is not connected, ask the user to open Packet Tracer and choose
Extensions > PT Visual MCP. - If the Packet Tracer menu is missing, tell the user to import and run
extension\packet-tracer-visual-mcp-script-engine.jsfrom this project.
Main Workflow
For IOS automation:
- Use
ptv_generateIosTemplatefor reusable static route, RIP, OSPF, EIGRP, DHCP pool, ACL, or NAT/PAT command blocks. - Use
ptv_generateCampusIosConfigto preview a complete campus config set. - Use
ptv_applyCampusIosConfigonly after the topology exists and the bridge is connected. - Use
ptv_applyIosConfigSetwhen applying a custom config set.
For validation:
- Use
ptv_validateCampusFastby default. It keeps validation quick by checking plan shape, build/apply results, one optional canvas snapshot, key devices, and link count. - Use
ptv_generateCampusValidationPlanwithvalidationMode: "standard"or"strict"only when the user explicitly wants slower IOS command checks. - Use
ptv_runShowCommandsandptv_getCommandLogfor targeted deep checks; do not claim full show-output parsing unless Packet Tracer exposes it. - For Server-PT DNS/Web/FTP graphical service toggles, call
ptv_probeServerServicesfirst if the user wants automation. Treat services as manual unless the probe reveals stable DNS/HTTP/FTP setter APIs.
For fault demos:
- Call
ptv_getFaultLibraryto list supported faults. - Call
ptv_injectFaultwithapply: falsefirst if the user wants to preview commands. - Call
ptv_injectFaultwithapply: trueto break the lab intentionally. - Call
ptv_repairFaultwithapply: trueto restore the lab.
What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

pt-visual-mcp is a skill published in the GitHub repository lyf94697-droid/packet-tracer-visual-mcp (1 stars, last pushed 2mo ago), licensed MIT. It adds 82 tokens to every session and 1,692 once invoked, about $0.0004 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
