Introduction
Status: MCP server — not publicly launched. This docs site is live;
mcp.feelyourprotocol.orgis planned. Until then, use the website explorations.
For most visitors
If you heard about Feel Your Protocol from the community or Bankr and want to explore Ethereum protocol changes interactively, start on the main site:
feelyourprotocol.org — browser explorations (textbook). No install, no MCP config.
This MCP docs site describes the lab equipment we are building: a headless server so agents can run the same problem sets with arbitrary inputs. That product is in progress — not something you connect to from the web today.
| What | Status | Who it is for |
|---|---|---|
| Website explorations | Live | Everyone — curiosity, learning, feeling the protocol |
Public MCP endpoint (mcp.feelyourprotocol.org) | Not launched | Agents and integrators — Connect when it ships |
What the MCP server will do (when launched)
Feel Your Protocol will provide a headless MCP server wrapping the EthereumJS stack so AI agents can run exact, deterministic simulations of the future Ethereum protocol — upcoming forks, EIPs, and research — and receive rich JSON traces they can reason over.
At launch the hosted server will expose four MCP tools — describe_capabilities, run_bytecode, run_transaction, and run_block. EIP catalogue pages describe how each exploration maps to agent prompts once you can connect.
Payments (x402) and additional tools (BAL generate) come with or shortly after the public endpoint.
Mental model
From the two-legs vision: the explorations website is the textbook; the MCP server is the lab equipment. The textbook is live; the hosted lab is not open yet.
For architecture, repositories, and build procedures, see Internals. For vision and draft concepts, see the roadmap site.
