These terms cover pflow.xyz, its API and its MCP connector at https://pflow.xyz/mcp, run by Matt York (stackdump). By using them you agree to these terms.
pflow.xyz is free. It lets you build, check, simulate and share Petri nets. Features may change, and the service may be paused or stopped. The source code is open at github.com/pflow-xyz/pflow-xyz under its own license.
Saving needs you to sign in: with GitHub in the editor, or with GitHub or Google from an MCP client. You are responsible for what is saved from your account, including saves made by an app you have signed in, such as Claude. You can revoke an app's access in your GitHub or Google account settings.
Saved nets are public and are recorded as saved by your account. You keep whatever rights you have in what you save. By saving it, you let pflow.xyz store it, show it and serve it to anyone with its link, for as long as the service runs. Only save what you have the right to share, and nothing private or confidential.
Don't use pflow.xyz to break the law, to store material that infringes others' rights or is harmful, or to disrupt the service, for example by flooding it with requests or trying to get around its limits or sign-in. We may remove content or block access that breaks these terms.
pflow.xyz is provided as is, without warranties of any kind. Results from its simulations and analyses can be wrong or incomplete; check anything that matters before relying on it.
To the extent the law allows, the operator of pflow.xyz is not liable for any loss or damage arising from your use of the service.
How we handle data is described in the privacy policy.
If these terms change, the new version will be posted here with a new date. Questions go to github.com/pflow-xyz/pflow-xyz/issues.
