The MCP server is live

6 October 2026. The public MCP server for the next Ethereum hardfork is open — the same day Glamsterdam reaches Sepolia. Agents connect to mcp.feelyourprotocol.org and run exact simulations under Glamsterdam rules: a program, a transaction, or a small block, before those rules are on mainnet.

The same changes are on feelyourprotocol.org, for a person to try by hand. The tool catalogue is on mcp-docs.

Open

No API key, no payment

Glamsterdam

The upcoming hardfork, plus mainnet forks back to Berlin

Hosted

Try it

Connect is one URL. Then ask something plain, for example: send 1 wei to an empty account under Amsterdam and read the gas a wallet would need. More prompts are on What you can ask.

What you can do

Six tools. An agent calls them by name.

Tool	What it does
describe_capabilities	Ask what this server can run: forks, EIPs, and which tool to call.
run_bytecode	Run a program under a named fork. Read the gas, the return value, and the trace.
run_transaction	Run a paid transaction and read the receipt.
run_block	Run a small lab block of one to eight transactions.
generate_artifact	Build a block access list from that same kind of block.
inspect_artifact	Check a structure you already have, such as a block access list, without chain state.

The catalogue on mcp-docs names which EIPs are runnable today. The explorations are the same changes, written for a person.

After this opening

The open server covers Glamsterdam and the forks already on mainnet. EIPs that are still ahead of that hardfork start on a paid tier a few weeks later, paid with x402 (USDC on Base). The first expected one is frame transactions (EIP-8141). Those EIPs join the open server when the next hardfork comes into view. The cycle is on Pricing.

You supply the accounts, the code, and the transactions. The server runs them in a fresh lab world. It does not read mainnet, compile Solidity, or replay history.

Where to go

• Connect: mcp-docs.feelyourprotocol.org/use/connect
• What you can ask: capabilities
• Explorations: feelyourprotocol.org
• Updates: X @FeelEthereum

The roadmap and the timeline are the longer view.
