A setup guide for connecting a running Petri Net Sim application to coding tools through MCP, a standard way for apps to share actions with AI agents.

It is for registering Petri Net Sim with Claude Code, Claude Desktop, Cursor, or another MCP client so an agent can build, edit, or simulate Petri nets.

It removes the manual connection work and helps investigate access errors such as 401 or 403 responses.

Token cost

What it costs to keep this loaded

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	$0.00067	$0.00715
Opus 5.5	$0.00027	$0.00286
Sonnet 5.5	$0.00013	$0.00143
Haiku 4.5	$0.00007	$0.00072

Security

Grade A, and why

connect-mcp scanned grade A with 1 finding 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 2mo 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.

Not a fault in itself. Listed so you know the mod talks to something, and to what.

The source is not reproduced here

A licence we could not identify

The repository carries a LICENSE file, but it is custom or dual enough that GitHub cannot name it and neither can this catalogue. Unknown terms are not permission, so the body is not copied here. Read the licence at the source and decide for yourself.

Changes

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.
