Terms
Last updated: 6 October 2026
Short version: this is a free lab for protocol experiments. Use it to learn and to check ideas. Verify anything you ship, because we do not guarantee that a result is correct.
These terms
These terms cover the hosted MCP server at https://mcp.feelyourprotocol.org/mcp and this documentation. By connecting your agent or client to the server, you accept them. The server is operated by Holger Drewes (see the imprint). The explorations website is a separate offer.
There is no account, and the lab is not an analytics product.
What you get
A deterministic lab run under a named Ethereum fork, using EthereumJS. The server does not read mainnet or any other chain, and it is not legal, financial, or security advice. See Limits for what it runs and what it does not.
What you send
You send bytecode, transactions, and demo accounts in each call. Do not send secrets, private keys, or anything you cannot share. Do not flood the server or use it to attack anyone.
The server is free. We may change, pause, or stop it. If a paid tier arrives (see Pricing), these terms will be updated before anyone is charged.
No warranty
The service is provided as is and as available. We build the lab with ordinary care: tests, pinned spec snapshots, and reviewed changes. That care does not guarantee a result is correct.
A result can be wrong or incomplete, and it can differ from another client or a later version of the spec. It applies to the inputs and the fork you sent. The same inputs give the same answer again, which is not a promise that the answer is the one to ship.
Liability
While the server is free, we are liable only for intent and gross negligence, as far as the law allows. Harm to life, body, or health is never excluded.
We are not liable for indirect or consequential loss from using a result. That includes lost funds, a wrong gas limit, a failed deploy, an audit conclusion, or what an agent tells you.
Decisions stay with you, including the ones your agent makes on your behalf. Check anything you rely on.
Changes and law
We may update this page. The date at the top is the version. German law applies, as far as the law lets us choose it. Questions go through the imprint.
